White Paper

My Comments

Telstra has fronted up with their latest premium portable mobile broadband router for the 5G mobile-broadband infrastructure. But this “Mi-Fi” known as the Telstra 5G Wi-Fi Pro ticks all the boxes as far as being future-proof is concerned.

Here, on the WAN (Internet) side, this device supports 5G with mmWave technology while on the LAN (local network) side, it works on the latest Wi-Fi 6 standard for 2.4GHz and 5GHz bands thus bringing your mobile network up to date with the latest standards.Of course it can work with existing 4G LTE networks and exploits what Telstra has to offer in this context.  This has a 4500mAh battery that can be removed and can run for nine hours providing full data transfer. It can be charged via a USB-C connection according to the QC 3.0 protocol and the open-frame Power Delivery 2.0 protocol, meaning you can charge it with your brand-new Ultrabook’s charger or run it for a long time using a USB-C PD powerbank.

The Telstra 5G Wi-Fi Pro costs AUD$599 straight up. Or you could buy this device on a post-paid Telstra service plan for AUD$24.95 / month on 24-month plan plus mobile data plan the cost of the mobile-broadband data service.

What is this mmWave 5G mobile broadband all about?

The mmWave 5G mobile broadband technology is an extremely-high-frequency variant of 5G mobile broadband technology which works between 24GHz to 100GHz. Telstra’s initial trial run of this technology at Gold Coast worked on 26GHz. The same technology has been sued with various fixed point-to-point wireless links and satellite-Internet services but is use as a mobile broadband technology is what is being identified here.

Due to the very short wavelength, mmWave 5G technology will have a short operating range of a few hundred metres from the base station. This means that to cover a significant area, the service provider will need to install many “femtocell” base stations across the area and they will typically operate at a signal strength similar to a Wi-Fi access point or router. It means that the electromagnetic energy levels are 1000 times below the maximum energy level expected for safe operation.

Therefore mmWave 5G technology is pitched for operating environments where there is a high concentration of users so as to avoid “loading” very few base stations with many users, thus denying the users adequate bandwidth. This is a situation most of us will have experienced when attempting to benefit from an Internet resource on our mobile devices while on a packed commuter train.

Here, you will see this technology be used at busy public-transport interchanges including airports; event venues like convention centres or sports stadiums; or shopping centres. You may even find it being used in high-rise residential, commercial and hotel developments where there is expected to be many people within the development.

At the moment, Telstra has to license the necessary spectrum in order to set up a mmWave 5G service and will need to see other devices come on board prepared for this technology.

mmWave 5G mobile broadband will simply be pressed in to service as a complementary technology to the existing 5G mobile broadband technologies. In this case it is about highly-concentrated operating environments with many devices.

The two-box voice-driven home assistant setup is being made real with Bluetooth

Article

Bang & Olufsen Beosound A1 2nd Generation Bluetooth smart speaker that works with a smartphone or similar devicce to benefit from Amazon Alexa

B&O Beosound A1 (2nd Gen) Announced With Alexa Integration | Ubergizmo

My Comments

At the moment, there is the latest generation of the Bose QuietComfort 35 noise-cancelling Bluetooth headset that implements a software link with the Google Assistant voice driven personal assistants through its own app. Now Bang & Olufsen have come up with the Beosound A1 Second Generation battery-operated Bluetooth speaker that has integration with the Amazon Alexa voice-driven home assistant platform.

But what are these about?

Bluetooth smart speaker diagram

How the likes of the B&O Beosound A1 work with your smartphone, tablet or computer to be a smart speaker

These are purely Bluetooth audio peripherals that connect to your smartphone which links with the Internet via Wi-Fi or mobile broadband. This is usually facilitated with a manufacturer-supplied app for that device that you install on your smartphone or tablet. You will also have to install the client software for the voice-driven assistant platform if your smartphone or tablet doesn’t have inherent support for that platform.

The Bose solution primarily used their app to “map” a secondary function button on the headset to activate Google Assistant. Then the B&O approach had the Beosound A1 and your smartphone or similar mobile-platform device work together as if it is an Amazon Echo.

Why do I see this as a significant trend for “smart-speaker” and allied device use cases, especially as Google, Amazon and the Voice Interoperability Initiative want to extend their voice-driven assistant platforms to setups based around Bluetooth audio peripherals. Here it underscores the reality that the highly-capable host devices will have Internet connectivity via a mobile-broadband connection or a local-area network.

One is to allow manufacturers to provide a highly-portable approach towards using Alexa or Google Assistant while on the move. Similarly, this approach will appeal to those in the automotive and marine infotainment sector with the idea of end-users bringing their own Internet connection with them while in their car or boat but wanting to use their preferred voice-driven assistant platform there.

Some technology manufacturers may look at the idea of a two-piece setup with a specially-designed Bluetooth speaker that links with a device that is normally connected to the Internet like a set-top box or router and both devices working in a smart-speaker capacity. Here, it can be about a cost-effective smart-speaker platform or to enable the use of battery-operated devices that use battery-efficient technologies.

After what Bose and B&O are doing, it could be about bringing the idea of a two-box smart-speaker setup for voice-driven assistant platforms opening up some interesting pathways.

My Comments

Of late, the personal-IT press have identified a 13” ultraportable laptop computer that has set a benchmark when it comes to consumer-focused computers of that class. This computer is the Dell XPS 13 family of Ultrabooks which are a regular laptop computer family that runs Windows and is designed for portability.

What makes these computers special?

A key factor about the way Dell had worked on the XPS 13 family of Ultrabooks was to make sure the ultraportable laptops had the important functions necessary for this class of computer. They also factored in the durability aspect because if you are paying a pretty penny for a computer, you want to be sure it lasts.

As well, it was all part of assuring that the end-user got value for money when it came to purchasing an ultraportable laptop computer.

In a previous article that I wrote about the Dell XPS 13, I compared it to the National Panasonic mid-market VHS videocassette recorders offered since the mid 1980s to the PAL/SECAM (Europe, Australasia, Asia) market; and the Sony mid-market MiniDisc decks offered through the mid-late 1990s. Both these product ranges were worked with the focus on offering the features and performance that count for most users at a price that offers value for money and is “easy to stomach”.

Through the generations, Dell introduced the very narrow bezel for the screen but this required the typical camera module to be mounted under the screen. That earnt some criticism in the computing press due to it “looking up at the user’s nose”. For the latest generation, Dell developed a very small camera module that can exist at the top of the screen but maintain the XPS 13’s very narrow bezel.

The Dell XPS 13 Kaby Lake 2-in-1 convertible Ultrabook variant

The Dell XPS 13 is able to be specified with the three different Intel Core CPU grades (i3, i5 and i7) and users could specify it to be equipped with a 4K UHD display option. The ultraportable laptop will have Intel integrated graphics infrastructure but the past two generations of the Dell XPS 13 are equipped with two Thunderbolt 3 ports so you can use it with an external graphics module if you want improved graphics performance.

There was some doubt about Dell introducing a 2-in-1 convertible variant of the XPS 13 due to it being perceived as a gimmick rather than something that is of utility. But they introduced the convertible variant of this Ultrabook as part of the 2017 Kaby Lake generation. It placed Dell in a highly-competitive field of ultraportable convertible computers and could easily place a focus towards “value-focused” 2-in-1 ultraportables.

What will this mean for Dell and the personal computer industry?

The question that will come about is how far can Dell go towards improving this computer. At the moment, it could be about keeping each generation of the XPS 13 Ultrabook in step with the latest mobile-focused silicon and mobile-computing technologies. They could also be ending up with a 14” clamshell variant of this computer for those of us wanting a larger screen size for something that comfortably fits on the economy-class airline tray table.

For the 2-in-1 variant, Dell could even bring the XPS 13 to a point where it is simply about value for money compared to other 13” travel-friendly convertible ultraportables. Here, they would underscore the features that every user of that class of computer needs, especially when it comes to “on-the-road” use, along with preserving a durable design.

Other computer manufacturers will also be looking at the Dell XPS 13 as the computer to match, if not beat, when it comes to offering value for money in their 13” travel-friendly clamshell ultraportable range. This can include companies heavily present in particular market niches like enterprise computing who will use what Dell is offering and shoehorn it to their particular niche.

Best value configuration suggestions

Most users could get by with a Dell XPS 13 that uses an Intel Core i5 CPU, 8Gb RAM and at least 256Gb solid-state storage. You may want to pay more for an i7 CPU and/or 16Gb RAM if you are chasing more performance or to spend more on a higher storage capacity if you are storing more data while away.

If there is an expectation to use your XPS 13 on the road, it would be wise to avoid the 4K UHD screen option due to the fact that this resolution could make your Ultrabook more thirstier to run on its own battery.

The 2-in-1 convertible variant is worth considering if you are after this value-priced ultraportable in a “Yoga-style” convertible form.

Conclusion

What I have found through my experience with the Dell XPS 13 computers along with the computer-press write-ups about them is that Dell has effectively defined a benchmark when it comes to an Intel-powered travel-friendly ultraportable laptop computer.

Product Review–Brother DSMobile DS-940DW mobile scanner

Introduction

I am reviewing the Brother DSMobile DS-940DW Wi-Fi mobile scanner which is a highly-portable pure-play document scanner pitched towards the mobile office.

This battery-powered mobile scanner can scan to a regular computer via a USB connection or via a Wi-Fi link , whether you are using the one it creates or an existing small or home Wi-Fi network. As well, you can use it to scan documents to your iOS or Android mobile device using a Wi-Fi link, either one it creates or an extant small network.

As well, you can use it offline to scan documents to a removable microSD card so you can then download them as files to your computer at a later stage. In this case, you can remove the card and install it in your computer’s SD card reader to get at your documents or while you have the scanner connected to your regular computer you see that SD card as a removable storage device with all your scanned documents.

The clamshell design makes it easy to remove jammed paper.

The Brother DSMobile DS-940DW Wi-Fi mobile scanner is powered from an internal rechargeable battery or an external USB-based power supply which you have to provide. That could be through your computer, a USB charger or a USB powerbank. But the same USB power supply also charges the battery whether you are running the scanner or not.

Connectivity and Setup

The Brother DS-940DW mobile scanner has an easy-to-find slider switch on the right-hand side that selects between SD card operation, direct USB connection and Wi-Fi network connection. This makes it easier for the user to switch between the mode appropriate to their scanning needs, be it to scan to their laptop via USB or to their mobile device via Wi-Fi or simply to scan to the installed SD card.

Direct connection

If you intend to use the Brother DS-940DW scanner with your regular computer via USB, you connect it to the host computer using a USB 3.0 cable supplied with the scanner.

But if your computer is equipped only with USB-C connectors like some new Ultrabooks or you use a USB-C charger to power your scanner, you would need to purchase a USB Type-C to  USB 3.0 microB cable (OfficeWorks Australia, Office Depot USA, B&H Photo Video USA,Walmart, Amazon) rather than use the supplied USB Type-A cable.

In this case, if you did use the scanner offline and scanned documents to an SD card installed within the machine, the SD card will be presented to your computer’s operating system as another logical storage volume. This is similar to what happens when you are using a USB memory stick or an SD card reader.

Wi-Fi network connection

The scanner can be connected to the computer via a USB cable or via a Wi-Fi network, whether one that it creates or an existing small network. But setting it up to work with an existing Wi-Fi network requires you to work it as its own Wi-Fi access point then log in to a specified Web page which has a “Wireless Setup Wizard” to associate it with the existing network. You can use WPS-based push-button or PIN setup if your access point or router supports these methods. For this function, there is a hardware button located on the side of the scanner near the operation mode switch.

I am identifying the issue of having this mobile scanner on an existing small Wi-Fi network due to the idea of setting up these mobile devices as part of a mobile network where there are more than two devices to be on that network. It is in addition to having this same device work as part of your home or small-business network.

When the Brother DSMobile DS-940DW mobile scanner is connected to the host computer via USB, it exposes a Mass Storage device class for the internal microSD card reader. This is in conjunction to vendor-specific devices that depend on the host computer running a Brother-supplied driver and scan-monitor software.

There is a default arrangement that if you enable Wi-Fi mode on the scanner, it will check for previously-configured networks before it goes to own-access-point mode which is indicated by a steady Wi-Fi light. Successful connection to a previously-configured network is simply identified by a steady Wi-Fi light after a bit of flashing.

Software installation

If you are setting the Brother DS-940DW mobile scanner to work with your regular computer, you would need to install the drivers from the Brother support Website for this machine to work. You will also be supplied with the Brother iPront&Scan software which can do most of the essential scanning tasks.

Brother throws in complementary software like a business-card scanning app so you can scan your pile of customers’ or business partners’ business cards in to a contact-management database. This is software you can install when you download the driver and software package or install at a later date.

Mobile users will need to install the Brother iPrint&Scan app from their mobile platform’s app store. Here, they will need to use this simple software to scan the documents in to their device and “take them further” as they see fit.

Document Handling

Scanning a standard A4 or letter document page

The Brother DSMobile DS-940DW can only handle one page at at time but can scan both sides of that page at once. The double-sided scanning approach is similar to some of Brother’s multifunction printers that use single-pass duplex scanning.

When you scan a document, you need to make sure that the black paper guide is lined up against the original document’s edge before you start the scanning process. Here, you are making sure that the document isn’t skewing or likely to jam.

To deal with paper jams, you press the front of the scanner above the document-feed slot in order to expose the scanning heads to remove the misfed original. Here, the “clamshell approach” makes it easier to rectify any paper jams.

Ready to scan an ID card of standard “credit-card” thickness and with embossing – it can.

The Brother DS-940DW was able to scan ID cards, even those with embossed characters properly. I would see this as being important where users have to scan them to prove a customer’s identity during an “on-the-road” transaction.

Walk-up functions

The Brother DS-940DW has a built-in SDHC-compliant microSD card drive so you can scan documents offline to a microSD card. This is presented to the host computer as a standard USB Mass Storage Device and you use your operating system’s file manager to get at your scanned files which exist on that SD card.

I wouldn’t really expect this to work properly with the idea of showing your scanned photos through a smart TV or similar device that has its own USB port. It is because most of these dedicated-purpose devices don’t do a good job at handling multiple-function devices connected to their USB ports thanks to their firmware not supporting USB hubs as a device class.

Computer functions

I have used the scanner with the Brother iPrint&Scan software and found that it is competent as a basic scanning package whether to store the scan to your computer’s file system or to an online storage service.

At the moment, the Brother iPrint&Scan desktop scanning software works on a “pull-scan” approach where you have to start the scanning job from the software rather than a “push-scan” approach pressing the machine’s START/STOP button to initiate the scan job. This is due to the scan monitor software associated with the machine and providing this functionality not installing properly. I have addressed this issue previously on this site due to various scan-monitor programs taking time to respond properly when you start a scan job on the printer or scanner, with the idea of operating systems undertaking this role.

The Brother DSMobile DS-940DW network mobile scanner works with the Brother iPrint&Scan mobile app available on both the Apple and Google app stores. Here, it worked properly where you can simply save the scan to your mobile device or share it with other apps that handle the supported file types using the “share to” shortcut that iOS and Android provide.

Scan speed and quality

The machine can scan the pages you feed through it quickly and yields a high-quality reproduction of these pages. I had tried it with an ordinary A4 document, a snapshot photo, two till receipts and two ID cards and this was proven for each of them. With the photo, there wasn’t any difference with the colour saturation that was yielded.

If you are scanning till receipts with the scanner, it is a good idea to set the machine or your scanning software to scan the receipt single-sided. This will avoid problems with reverse-side text that may “come through” during the scan which may be a problem with receipts coming from devices that are loaded with “branded” paper that has advertising material printed on the back.

Limitations And Points Of Improvement

A key issue that I found with the Brother DS-940DW mobile scanner was a poor user experience when I enrolled it with an existing Wi-Fi home network from my smartphone. This could be improved upon through having a native mobile platform app for configuring this scanner’s network connectivity. It can include the ability to transfer a network’s connection details that are stored in your mobile device to the scanner as part of configuring that device.

For those of us who use a regular computer and the scanner’s Web user experience for configuring it to work with an existing Wi-Fi network, that user experience could be improved with an indicator that highlights successful connection to that network. As well, a hardware switch could be used to toggle between the scanner’s own network and an existing network, which may come in handy for troubleshooting or if you don’t want to use an existing network that you set up the scanner for.

It could also benefit from the full set of USB 3.1 specifications including the Type-C connection and USB Power Delivery for quick charging. Most likely I would see Brother offer this connection in a newer portable printing devices as the USB Type-C connection becomes the norm for portable computer equipment.

I also see the Brother DSMobile DS-940DW network mobile scanner being an ideal device to implement Mopria Scan driver-free scanning technology (Mopria Alliance press release PDF) which is currently implemented as an app for Android devices.

As well, it could support a transparency-scanning mode that capitalises on the single-pass auto-duplex scan method. Here, one of the scanning heads could simply be a white backlight while the other simply reads the image on the film. This would come in to its own with a wide range of applications like photographers with their negatives and slides, the medical profession with their film-based X-rays or businesses who have archived documents using microfilm and similar technologies.

Conclusion and Placement Notes

I do see the Brother DSMobile DS-940DW network mobile scanner as an agile highly portable pure-play document scanner that can answer many different needs. Here, it works well with anyone whose office is the driver’s seat of a car or the back of a van and can even answer the requirements to use mobile-platform devices as one’s primary workplace technology.

It is easy to consider a mobile scanner, especially a network-capable machine, to be a toy but I do see the Brother DSMobile DS-940DW mobile scanner as a tool. This is more so for mobile workers who need to scan receipts for work transactions incurred while travelling or to scan documents such as work authorisations and customer ID at the customer’s premises.

The fact that you can switch between scanning to an SD card, a USB-connected host or a Wi-Fi-connected host using a hardware switch makes the job of selecting the right mode for the job easier. For example, a mobile professional could switch the scanner over to “scan-to-card” mode and scan the fuel receipt to an SD card installed in the unit and serving as a “digital receipt shoebox”. Then they scan that work authorisation that their customer had signed when they visited and use the Wi-Fi link with their iPad running an email app to send the signed authorisation to their office.

Reverse image searching–a very useful tool for verifying the authenticity of content

Tineye reverse image search

Tineye – one of the most popular and useful reverse image search tools

Article

How To Do A Reverse Image Search From Your Phone | PCMag

My Comments and further information

Increasingly, most of us who regularly interact with the Internet will be encouraged to perform reverse-image searches.

This is where you use an image you supply or reference as a search term for the same or similar images on other Internet resources. It can also be about identifying a person or other object that is in the image.

Increasingly this is being used by people who engage in online dating to verify the authenticity of the person whom they “hit” on in an online-dating or social-media platform. It is due to romance scams where “catfishing” (pretending to be someone else in order to attract people of a particular kind) is part of the game. Here, part of the modus operandi is for the perpetrator to steal pictures of other people that match a particular look from photo-sharing or social-media sites and use these images in their profile.

It also is being used as a way to verify the authenticity of a product being offered for sale through an online second-hand-goods marketplace like eBay, Craigslist or Gumtree. It also extends to short-term house rentals including AirBnB where the potential tenant wants to verify the authenticity of the premises that is available to let.

As well, reverse image searching is being considered more relevant when it comes to checking the veracity of a news item that is posted online. This is very important in the era of fake news and disinformation where online images including doctored images are being used to corroborate questionable news articles.

How do you do a reverse image search?

At the moment, there are a few reverse-image-search engines that are available to use by the ordinary computer user. These include Tineye, Google Image Search, Bing Visual Search, Yandex’s image search function and Social Catfish’s reverse-image-search function.

Dell Inspiron 14 5000 2-in-1 at Rydges Melbourne (Locanda)

A regular computer like this Dell Inspiron 14 5000 2-in-1 makes it easier to do a reverse image search thanks to established operating system and browser code and its user interface.

The process of using these services involves you uploading the image to the service including using “copy-and-paste” techniques or passing the image’s URL to an address box in the search engine’s user interface. The latter method implies a “search-by-reference” method with the reverse-image-search site loading the image associated with that link into itself as its search term.

Using a regular desktop or laptop computer that runs the common desktop operating systems makes this job easier. This is because the browsers offered on these platforms implement tabs or allow multiple sessions so you can run the site in question in one tab or window and one or two reverse-image-search engines in other tabs or windows.

These operating systems also maintain well-developed file systems and copy-paste transfer algorithms that facilitate the transfer of URLs or image data to these reverse-image-search engines. That will also apply if you are dealing with a native app for that online service such as the client app offered by Facebook or LinkedIn for Windows. As well, Chrome and Firefox provide drag-and-drop support so you can drag the image from that Tinder or Facebook profile in one browser session to Tineye running in the other browser session.

But mobile users may find this process very daunting. Typically it requires the site to be opened and logged in to in Chrome or Safari then opened as a desktop version which is the equivalent of viewing it on a regular computer. For Chrome, you have to tap on the three-dot menu and select “Request Desktop Site”. For Safari, you have to tap the upward-facing arrow to show the “desktop view” option and select that option.

Then you open the image in a new tab and copy the image’s URL from the address bar. That is before you visit Google Image Search or Tineye to paste the URL in that app’s interface.

Google has built in to recent mobile versions of Chrome a shortcut to their reverse-image-search function. Here, you “dwell” on the image with your finger to expose a pop-up menu which has the “Search Google For This Image” option. The Bing app has the ability for you to upload images or screenshots for searching.

Share option in Google Chrome on Android

Share option in Google Chrome on Android

If you use an app like the Facebook, Instagram or Tinder mobile clients, you may have to take a screenshot of the image you want to search on. Recent iOS and Android versions also provide the ability to edit a screenshot before you save it thus cutting out the unnecessary user-interface stuff from what you want to submit. Then you open up Tineye or Google Image Search in your browser and upload the image to the reverse-image-search engine.

How can reverse image searching on the mobile platforms be improved

What can be done to facilitate reverse image searching on the mobile platforms is for reverse-image-search engines to create lightweight apps for each mobile platform. This app would make use of the mobile platform’s “Share” function for you to upload the image or its URL to the reverse-image-search engine as a search term. Then the app would show you the results of your search through a native interface or a view of the appropriate Web interface.

Share dialog on Android

A reverse-image-search tool like Tineye could be a share-to destination for mobile platforms like iOS or Android

Why have this app work as a “share to” destination? This is because most mobile-platform apps and Web browsers make use of the “share to” function as a way to take a local or online resource further. It doesn’t matter whether it is to send to someone else via a messaging platform including email; obtain a printout or, in some cases, stream it on the big screen via AirPlay or Chromecast.

The lightweight mobile app that works with a reverse-image-search engine answers the reality that most of us use smartphones or mobile-platform tablets for personal online activity. This is more so with social media, online dating and online news sources, thanks to the “personal” size of these devices.

Conclusion

What is becoming real is reverse image searching, whether of particular images or Webpages, is being seen as important for our security and privacy and for our society’s stability.

It is worth enquiring about the kind of Wi-Fi Internet service at your hotel or holiday rental you intend to stay at

Article

Harbourside Apartments - one of those serviced-apartment blocks that could benefit from DLNA

If you do value online connectivity, it is worth asking your hotel, motel, holiday rental or similar accommodation about that Wi-Fi Internet service they offer

Ask About A Hotel Or Airbnb’s WiFi Before You Book | Lifehacker

My Comments

When you book that hotel, motel or holiday-rental house like an AirBnB, it may be worth inquiring about the kind of Wi-Fi service the venue has. This is more so where they advertise the availability of Wi-Fi as a headline feature.

In some of these venues, you may come across situations that may impact your online life during your stay.

For example, you may come across a short-term holiday rental that is set up with an el-cheapo Internet-service plan where there isn’t much in the way of included data allowance and the use of multimedia content like Netflix, Internet radio or YouTube; or IP-based voice and video telephony by guests may chew through this allowance. Similarly, the facility may only be provided with a connection that doesn’t have much in the way of bandwidth, a reality with properties located out of major towns.

Hotels and similar locations can have their fair share of Wi-Fi Internet limitations. For example, they could include baseline Wi-Fi Internet for one device as part of the accommodation deal but charge extra for higher bandwidth or concurrent use of more devices. Or you may find that it is an optional extra that is charged for separately.

Similarly you may find that the hotel’s Internet service underperforms during peak occupancy especially when many guests are streaming online multimedia content like Netflix concurrently.

Some of us may see this as a deal-maker or deal-breaker when it comes to booking that accommodation facility depending on what level of priority we give to Internet access while on the road. It may be more important when we engage in videocalling as a way to “touch base”, upload photos to an online album or social media, or enjoy online video content during the evening. As well, it can be of concern where multiple people like a family are using the connection concurrently.

The venue may also see your interest in its guest-access Internet as a way to improve their offering especially when they are in a position to “re-contract” their Internet service to a better tariff. If they are in a truly-competitive market, they could easily end up placing the service on a tariff that offers a “better bang for the buck”. This is by offering more bandwidth and data usage (where applicable) for the same amount that they previously paid or for less.

As well, it may appeal to rental-premises owners who want to see value in renting out their short-let venue for longer periods at a time. It can also help them to court the business community who may use these places as a base to stay while doing business in the local area.

It is still worth it to raise questions about the Internet service you may end up with while on the road. This is because it can benefit both you and the venue owner in various ways.

My Comments

A feature that is asked for with smartphones and tablets is to support fast battery charging as well as the ability to operate the mobile device on external power while it charges.

Dell XPS 13 2-in-1 Ultrabook - USB-C power

… to have the same kind of USB-C power-supply connectivity as this Dell XPS 13 2-in-1 Ultrabook

Typically this was satisfied by USB battery chargers working up to 5V 2.4A and feeding the device from a USB Type-A socket to a USB Micro-B, USB-C or Apple Lightning (MFi) port. As well, chipset manufacturers like Qualcomm introduced proprietary fast-charge solutions that different phone manufacturers implemented. These required the use of chargers that had the corresponding chipset circuitry and often they were offered by the phone’s manufacturer as a supplied or “official” accessory.

But Google are now requiring that Android devices that have a USB-C connection are to fully support USB Power Delivery. This was initially a recommended feature but from September 2019 it will be a mandatory feature for new Android smartphones to gain full software support like Google Play Services and the Google Play Store.

USB Power Delivery is already implemented as the power source for laptops like recent iterations of the Dell XPS 13 or Apple MacBook Air or as a power-source option for USB-C-equipped laptops like the Dell Inspiron 14 5000 2-in-1 convertible laptop. This is augmented with the availability of power-supply devices working to this standard such as battery packs or USB-C monitors.

Here, Google wants to implement the USB-PD standard for the Android platform for a number of reasons. Here USB-PD implements a standard voltage-and-current ladder to supply power to the device according to what the power-supply device can offer and what the device can take. Therefore an Android device manufacturer can design a device to take the right power level to, perhaps, facilitate fast-charging or high-performance operation while connected to a USB-PD power source.

As well, the standard is a known common standard that is managed by USB Implementers Forum rather than a device or chipset vendor for the benefit of the industry. This puts less pressure on power-supply vendors to cater to different proprietary fast-charging requirements.

This standard will also accelerate the availability of USB-PD-compliant power-supply designs for every sort of application and at price points that appeal to everyone. It can also encourage innovation when it comes to power-supply design whether this is for one or more devices or to work from an internal battery, 100-250V AC mains power or 12-24V DC vehicle/marine/aircraft power.

Householders won’t even have to worry about the number of USB chargers available that will charge their mobile device quickly. As well, the environment will benefit because of the reduced number of useable chargers going to landfill but the reality with these chargers is that they are still kept available as “spare” or “convenience” chargers until they fail to function.

USB Power Delivery can also allow for a mobile device to be a power source for a peripheral like a portable hard disk or a USB digital noise-cancelling headset. This may require the mobile device to be equipped with two USB-C sockets if it is to be of use with people who need to be able to run their devices from external power.

Personally, I could see this happening that someone will engineer a cost-effective way to have a USB-PD-compliant power supply to simply be a general-purpose power supply. This will end up with this technology being used simply to power all sorts of lighting, novelties and other devices, like what is happening with the current USB specification.

Google’s approach with mandating the use of USB Power Delivery for all Android mobile devices equipped with USB-C connectors will keep up Android’s fame as the mobile platform built on common open standards.

Amazon and Leading Technology Companies Announce the Voice Interoperability Initiative (Press Release)

My Comments

Amazon have instigated the Voice Interoperability Initiative which, at the moment, allows a hardware or software device to work with multiple compatible voice-driven AI assistants. It also includes the ability for someone to develop a voice-driven assistant platform that can serve a niche yet have it run on commonly-available smart-speaker hardware alongside a broad-based voice-driven assistant platform.

An example they called out was to run the Salesforce Einstein voice-driven assistant that works with Salesforce’s customer-relationship-management software on the Amazon Echo smart speaker alongside the Alexa voice assistant. Similarly, a person who lives in France and is taking advantage of the highly-competitive telecommunications and Internet landscape there by buying the Freebox Delta smart speaker / router and have it use Free.fr’s voice assistant platform or Amazon Alexa on that same device.

Microsoft, BMW, Free.fr, Baidu, Bose, Harman and Sony are behind this initiative while Google, Apple and Samsung are definitely absent. This is most likely because Google, Apple and Samsung have their own broad-based voice-driven assistant platforms that are part of their hardware or operating-system platforms with Apple placing more emphasis on vertically-integrating some of their products. It is although Samsung’s Android phones are set up to be able to work with their Bixby voice assistant or Google’s Assistant service.

Intel and Qualcomm are also behind this effort by offering silicon that provides the power to effectively understand the different wake words and direct a session’s focus towards a particular voice assistant.

The same hardware device or software gateway can recognise assistant-specific wake words and react to them on a session-specific basis. There will be the ability to assure customer privacy through measures like encrypted tunnelling for each assistant session along with an effort to be power-efficient which is important for battery-operated devices.

Personally I see this as an ability for companies to place emphasis on niche voice-assistant platforms like what Salesforce is doing with their Einstein product or Microsoft with its refocused Cortana product.  It can even make the concept of these voice assistants more relevant to the enterprise market and business customers.

Similarly, telcos and ISPs could create their own voice-driven assistants for use by their customers, typically with functionality that answers what they want out of the telco’s offerings. It can also extend to the hotel and allied sectors that wants to use voice-driven assistants for providing access to functions of benefit to hotel guests like room service, facility booking and knowledge about the local area. Let’s not forget vehicle builders who implement voice-driven assistants as part of their infotainment technology so that the drive has both hands on the wheel and eyes on the road.

This kind of offering can open up a market for the creation of “white-label” voice-assistant platforms that can be “branded” by their customers. As well, some of these assistants can be developed with a focus towards a local market’s needs like high proficiency in a local language and support for local values.

For hardware, the Amazon Voice Interoperability Initiative can open up paths for innovative devices. This can lead towards ideas like automotive applications, smart TVs, build-in use cases like intercom / entryphone or thermostat setups, software-only assistant gateways that work with computers or telephone systems amongst other things.

With the Amazon Voice Interoperability Alliance, there will be increased room for innovation in the voice-driven assistant sector.

My Comments

More of the Thunderbolt-3 external graphics modules are appearing on the scene but most of these units are primarily heavy units with plenty of connectivity on them. This is good if you wish to have this external graphics module as part of your main workspace / gaming space rather than something you will be likely to take with you as you travel with that Dell XPS 13 Ultrabook or MacBook Pro.

Dell XPS 13 9360 8th Generation clamshell Ultrabook

Dell XPS 13 9360 8th Generation clamshell Ultrabook – an example of an ultraportable computer that can benefit from one of the portable external graphics modules

Windows Central have called out a selection of these units that are particularly portable in design to allow for ease of transport. This will appeal to gamers and the like who have access to a large-screen TV in another room that they can plug video peripherals in to such as university students living in campus accommodation or a sharehouse. It can also appeal to those of us who want to use the laptop’s screen with a dedicated graphics processor such as to edit and render video footage they have captured or play a game with best video performance.

Most of the portable external graphics modules will be embedded with a particular graphics chipset and a known amount of display memory. In most cases this will be a high-end mobile GPU which may be considered low-spec by desktop (gaming-rig) standards. There will also be reduced connectivity options especially with the smaller units but they will have enough power output to power most Thunderbolt-3-equipped Ultrabooks.

An exception that the article called out was the Akitio Node Pro which is a “card cage” that is similar in size to one of the new low-profile desktop computers. This unit also has a handle and a Thunderbolt-3 downstream connection for other peripherals based on this standard. It would need an active DisplayPort-HDMI adaptor or a display card equipped with at least one HDMI port to connect to the typical large-screen TV set.

Most of the very small units or units positioned at the cheap end of the market would excel at 1080p (Full HD) graphics work. This would be realistic for most flatscreen TVs that are in use as secondary TVs or to use the laptop’s own screen if you stick the the advice to specify Full HD (1080p) as a way to conserve battery power on your laptop.

The exception in this roundup of portable external graphics modules was the AORUS Gaming Box which is kitted out with the NVIDIA GeForce GTX 1070 graphics chipset. This would be consided a high-performance unit.

Here, these portable external graphics modules are being identified as being something of use where you are likely to take them between locations but don’t mind compromising when it comes to functionality or capability.

It can also appeal to first-time buyers who don’t want to spend much on their first external graphics module to put a bit of “pep” in to their suitably-equipped laptop’s or all-in-one’s graphics performance. Then if you are thinking of using a better external graphics module, perhaps a “card-cage” variety that can work with high-performance “gaming-rig” or “desktop-workstation” cards, you can then keep one of these external graphics modules as something to use on the road for example.

Major improvements expected to come to Bluetooth audio

Article

The Bluetooth connectivity that the Creative Labs Stage Air desktop soundbar benefits from will be improved in an evolutionary way

The future of Bluetooth audio: Major changes coming later this year | Android Authority

My Comments

One of Bluetooth’s killer applications, especially for smartphones and tablets, is a wireless link between a headset, speaker or sound system to reproduce audio content held on the host computing device.

At the moment, the high-end for this use case is being fought strongly by some very determined companies. Firstly, Bose, Sony and Bang & Olufsen are competing with each other for the best active-noise-cancelling over-the-ear Bluetooth headset that you can use while travelling. This is while Apple and Sony are vying for top place when it comes to the “true-wireless” in-ear Bluetooth headset. It is showing that the Bluetooth wireless-audio feature is infact part of a desirable feature set for headphones intended to be used with smartphones, tablets or laptops.

Let’s not forget that recently-built cars and recently-made aftermarket car-stereo head units are equipped with Bluetooth for communications and multimedia audio content. This is part of assuring drivers can concentrate on the road while they are driving.

JBL E45BT Bluetooth wireless headset

.. just like headsets like this JBL one

But this technology is to evolve over the second half of 2019 with products based on the improved technology expected to appear realistically by mid 2020. Like with Bluetooth Low Energy and similar technologies, the host and accessory devices will be dual-mode devices that support current-generation and next-generation Bluetooth Audio. This will lead to backward compatibility and “best-case” operation for both classes of device.

There is an expectation that they will be offered at a price premium for early adopters but the provision of a single chipset for both modes could lead towards more affordable devices. A question that can easily be raised is whether the improvements offered by next-generation Bluetooth audio can be provided to current-generation Bluetooth hosts or accessory devices through a software upgrade especially where a software-defined architecture is in place.

What will it offer?

USB-C connector on Samsung Galaxy S8 Plus smartphone

… like with the upcoming generation of smartphones

The first major feature to be offered by next-generation Bluetooth audio technology is a Bluetooth-designed high-quality audio codec to repackage the audio content for transmission between the host and accessory.

This is intended to replace the need for a smartphone or headset to implement third-party audio codecs like aptX or LDAC if the goal is to assure sound quality that is CD-grade or better. It means that the device designers don’t need to end up licensing these codecs from third parties which will lead to higher-quality products at affordable prices along with removing the balkanisation associated with implementing the different codecs at source and endpoint.

A question that will be raised is what will be the maximum audio quality standard available to the new codec – whether this will be CD-quality sound working up to 16-bit 48kHz sampling rate or master-quality sound working up to 24-bit 192kHz sampling rate. Similarly, could these technologies be implemented in communications audio especially where wide-bandwidth FM-grade audio is being added to voice and video communications technologies for better voice quality and intelligibility thanks to wider bandwidth being available for this purpose.

Another key improvement that will be expected is reduced latency to a point where it isn’t noticeable. This will appeal to the gaming headset market where latency is important because sound effects within games are very important as audio cues for what is happening in a game. It may also be of benefit if you are making or taking videocalls and use your Bluetooth headset to converse with the caller. Here, it will open up the market for Bluetooth-based wireless gaming headsets.

It will also open up Bluetooth audio towards the “many-endpoint” sound-reproduction applications where multiple endpoints like headsets or speakers receive the same audio stream from the same audio source. In these use cases, you can’t have any endpoint receiving the program material reproducing the material later than others receiving the same material.

A key application that will come about is to implement Bluetooth in a multiple-channel speaker setup including a surround-sound setup. This will be a very critical application due to the requirement to reproduce each channel of the audio content stream concurrently and in phase.

It will also legitimise Bluetooth as an alternative wireless link to Wi-Fi wireless networks for multiroom audio setups. As well, the support for “many-endpoint” sound-reproduction will appeal to headsets and hearing-aid applications where there is the desire to send content to many of these devices using a high-quality wireless digital approach rather than RF or induction-loop setups that may be limited in sound quality (in the case of induction-loop setups) or device compatibility (in the case of RF setups). There could even be the ability to support multiple audio-content channels in this setup such as supporting alternative languages or audio description. In some cases, it may open up a use case where transport announcements heard in an airport or rail station can “punch through” over music, video or game sound-effects heard over a Bluetooth headset in a similar way to European car radios can be set up to allow traffic bulletins to override other audio sources.

A question that can be raised with the “many-endpoint” approach that this next-generation Bluetooth-audio technology is to support is whether this can support different connection topologies. This includes “daisy-chaining” speakers so that they are paired to each other for, perhaps a multi-channel setup; using a “hub-and-spoke” approach with multiple headsets or speakers connected to the same source endpoint; or a combination of both topologies including exploiting mesh abilities being introduced to Bluetooth.

Conclusion

From next year, as the newer generations of smartphones, laptops, headsets and other Bluetooth-audio-capable equipment are released, there will be a gradual improvement in the quality and utility of these devices’ audio functions.
