Multiple wireless-broadband devices – could a MiFi, tethered smartphone or similar device be the answer?

Should mobile carriers charge a premium for tethering your mobile phone to your computer

My Comments

Verizon have started work on heading towards making shared / family data plans available to consumers and small-business owners who buy wireless-broadband service in their markets in the USA. They would appeal to people who run multiple devices that benefit from wireless-broadband service, such as the typical user who runs a smartphone and a tablet like an iPad. They will typically have a larger data allowance which is shared amongst the multiple devices in a similar way that voice-call minutes or text-message units are shared amongst mobile phones that are part of a family plan.

This may be offered as an alternative to tethering a laptop or tablet to a smartphone and may place their business model centred around the “tethering premiums” in jeopardy. But this can still lead to the goal of increased revenue per customer by them offering larger data allowances for the shared plans, especially as most of us buy data allowances in a way to provide some sort of “buffer” for usage peaks. But, for these plans to work well, they need to support sufficiently large allowances and allow a user to connect a maximum of between five to ten devices to the service; or 15-20 for a family / household plan. This can cater for different usage patterns including newer device classes such as cameras or vehicle infotainment systems with integrated wireless-broadband modems; as well as families that are very “switched-on” when it comes to technology.

The same “shared data plan” can be implemented by fixed-broadband Internet providers that implement data allowances in their business models like most of the ISPs serving the Australian market. Here, they could cater for users who maintain two or more Internet services like a service set up at their holiday house, city apartment or business premises as well as the service that is used at their main home. The service providers could then allow for a larger data allowance to be used between the locations with minimal allowance wastage due to underused locations. In some ways, it could allow those service providers who sell fixed and mobile Internet service, like most telcos to run service plans with larger aggregate data allowances that cover fixed and mobile use.

Any telecommunications carrier or Internet service provider who runs or intends to run a data-allowance model should then keep an eye on Verizon’s shared-data-plan model and assess whether to run it with their current business model. Similarly, the carriers could examine ways of taking this further with “virtual LANs” that exist across the devices on the same plan and consistent security / “clean-feed” parental-control parameters across all devices associated with an account.

Product Review–Nokia BH-111 Bluetooth Audio Adaptor

Introduction

You have a pair of good-sounding B&O, Bose or Sennheiser headphones but want to use them as a full-blown headset with your smartphone. You may also want to try them with your laptop or desktop computer when you are playing a game or using a softphone app like Skype.

The only solution would be to buy a wired or Bluetooth headset that connects to the computer or phone. But these would make your good headphones redundant. Therefore you would need to look for an audio adaptor with an integrated microphone so you benefit from full handsfree communication.

The only problem with a lot of the wired audio adaptors supplied by the phone manufacturers and third-party accessories suppliers is that you may not be sure that they will work properly with your phone. This is more so if you jump mobile platform every time the contract expires. Similarly, wired audio adaptors can be hard to find because the only device to be seen using with your mobile phone is a Bluetooth headset.

There is also a greater risk of failure with wired audio adaptors as they are used in that the wiring at the device plug can be easily damaged through regular use and storage, thus impairing the quality of phone calls with these devices as I have experienced.

The Nokia BH-111 Bluetooth Audio Adaptor itself

But wait, I have come across the Nokia BH-111 Bluetooth Audio Adaptor which connects to a set of regular headphones, comverting them in to a Bluetooth stereo headset. It comes with a set of in-ear earphones but these may come in handy as “emergency spares” or for compact-use requirements. It is available in three different colours – black, white and a “hot-pink” colour and retails for AUD$50, making it fit within gift-pricing range.

This kit is centred around a small fob that houses a microphone, control buttons, rechargeable battery and Bluetooth transceiver. You can connect the supplied earphones or a pair of headphones to a 3.5mm stereo jack on the end of the fob’s “hinge pin” and this fob can clip on one’s shirt or tie like a lapel microphone.

The operation buttons are each edge of the face of the fob, with one “multifunction” button that is used primarily to make or take calls, a previous-track button, a next-track button and a play-pause button that can mute the microphone during calls as well as start and stop the music. The hinge pin on this fob has a knob for adjusting the sound volume opposite to where the headphones are plugged in to.

When you charge this Bluetooth audio adaptor, you plug the supplied battery charger or a USB-2.5mm DC cord in to the side of the “hinge pin”; and it doesn’t take long to charge this adaptor.

The Nokia BH-111 complies to the following Bluetooth device classes: Hands-Free Profile, Headset Profile, A2DP audio playback profile and AVRCP audio controller profile. It can store pairings for up to five physical devices at a time and can only connect to one Hands-free or Headset Profile device and one A2DP / AVRCP audio-player device at a time. This could allow you to work it with a Bluetooth smartphone and a separate Bluetooth-capable MP3 player at the same time.

Now these good headphones work as a stereo Bluetooth headset for your smartphone

The clip can be very stiff and hard to attach to a thick tie or suit coat but can work with most shirts. But it doesn’t look like something that could break easily after regular usage.

Setup and Usage

You have to use the “multifunction” button to turn the unit on and off as well as make it open for pairing. Here, you have to turn the audio adaptor off, then hold the multifunction button down until you hear a five-beep sequence, followed by a silence then a distinct beep. Then you start your device in “Bluetooth-device-scan” mode and it will show up as “Nokia BH-111” on the device’s user interface.

On the other hand, you hold the multifunction button down until you hear the five-beep sequence complete, then release this button in order to turn the audio adaptor on.

The Nokia BH-111 can act in a very confused manner if two or more devices that are paired with it are in the vicinity. This can happen more so if it is still connected to a mobile phone while a computer associated with it is nearby.

When the phone rings, you hear the Nokia ringtone rather than your handset’s ringtone, which can be confusing when you take a call through the audio adaptor for the first time and your phone plays its own ringtone through its speaker. I would rather that the phone’s ringtone plays through the headphones when a call comes in.

Battery Runtime and Sound Quality

For battery life, the Nokia BH-111 audio adaptor can complete a day of music-playback use with a Bluetooth mobile phone and longer in a quiescent state. It works properly and clearly when making and taking calls – the caller can hear and understand my voice properly and I can hear their properly as if I was using the phone handheld. I noticed this more with quieter environments but the intelligibility for the sound degrades if I was in a noisier environment.

The audio quality for music playback doesn’t change from what is offered by a wired connection to the phone, although there may be jitter occurring if the phone is “overloaded” with other tasks.

Limitations and Points Of Improvement

The clip could be improved on with a lever-type action similar to a clothes peg so it can easily clip to thicker material such as winter clothing or formal wear. The functions could also be marked in a colour inverse to the finish so it is easier to discover them.

It could be beneficial for a device like the Nokia BH-111 to have a 3.5mm input jack so you can connect other personal-audio devices to this adaptor, with the call audio from the Bluetooth phone cutting over sound from the connected personal-audio device. This could benefit people who use a high-capacity iPod Classic or similar device as their music library, listen to broadcast content from a personal radio or play content on legacy formats like cassettes or CDs using a device like a Walkman or Discman.

Similarly I would like to see a function that allows the audio adaptor to work as a speakerphone when connected to other audio equipment that uses speakers rather than a set of headphones. This may appeal to those of us who want to connect it to a car sound system via the AUX-IN jack or cassette adaptor for cassette-based equipment and use Blu-Tack to secure the fob to the dashboard for a high-quality reliable Bluetooth handsfree / music-player setup in a borrowed or hired vehicle.

An improved unit could implement a microphone array as a way of focusing the sound on the user’s voice in a phone conversation, and could place this leagues ahead of the typical Bluetooth headset.

Conclusion

The Nokia BH-111 headphone adaptor is infact the first product of its kind on the market that permits one to use their favourite headphones as a reliable calls-and-music Bluetooth headset for their smartphone especially if they use it for more than just phone calls.

The idea of the convertible ultrabook becomes real with ASUS

Asustek to showcase swivel-screen notebook at 2012 Computex | DigiTimes

Un ultrabook convertible chez Asus ? | Le Journal Du Geek (France – French language)

My Comments

A question that many people will be pondering nowadays when they consider a secondary computing device is whether to get a small laptop computer like a netbook or Ultrabook or a tablet computer like the iPad along with an accessory keyboard. There will be the tradeoffs of each platform such as software availability and user-interface requirements.

This will become more so when Windows 8 with its Metro touch user interface being part of the operating system and becoming another full-bore competition to the Apple iOS platform.

But ASUS have answered with an Ultrabook that can bridge between the notebook / laptop and tablet form factors in the cost-effective and power-efficient way that has been required of the Ultrabook. This machine will be the first “convertible” Ultrabook that has the “swivel-head” screen design like what I have experienced with the Fujitsu TH550M convertible notebook.

This will work tightly with the integrated touchscreen interface that Windows 8 provides rather than the previous practice where the manufacturers fabricated their own touch-optimised shell for these computers.

The ASUS convertible Ultrabook could offer a tablet-style user interface for casual computing needs yet have the full proper keyboard that would appeal to us when working on emails or documents; yet it will have the benefits that tablets like the iPad offer like quick start-up and long battery runtimes.

The main question is that whether other manufacturers would make the convertible Ultrabook form factor and make these computers cost-effective and widely available or will they be taken in by just supplying tablets as a distinct touchscreen product class?

Renault debuts in-dash Android system concept with app market

Renault debuts R-Link, an in-dash Android system with app market — Engadget

My Comments

The Android operating system isn’t just in your hands anymore with a tablet or smartphone. Renault has made sure it will be in the dashboard of the car, together with an app store to back the concept.

There is a main questions that I have about the concept at the moment. One is whether the system will use an updatable wireless-broadband link or a Wi-Fi network or both for data transfer to and from the network?

But what I see of the idea is the main use of the apps for driver and passenger entertainment, in the form of DLNA-based synchronisation of media with the home network, Internet radio (vTuner and similar Internet-radio directories, Last.FM, Pandora, etc) and similar applications. But there are other app ideas like advanced navigation including “book-ahead” functionality and roadside-telematics integration, and car statistics monitoring.

There could even be the ideas of using this Android platform to integrate the vehicle with home automation. The most obvious scenario that would come to mind would be looking at the dashboard to know whether the garage door that should be closed is infact closed and then touch a button to close it. This could avoid the need to look at the rear-view mirror as you drive out to check on the garage.

At least this effort by Renault with the Android platform could become a platform for developing in-vehicle infotainment and telematics systems and applications.

Setting up your smartphone or tablet for email

You may have your Web-based or client-based email system going strong on your regular computer but you have just joined the hordes and bought a new iPhone or Android smartphone or tablet.

One of the main advantages of these devices is that you can use them to check on your email and send simple email messages or replies. But you need to set up your email to work with these devices before you can use this benefit.

What you need to know

You will need to know the following details:

  • what kind of email setup you are using
    This could be your the name of your Web-based email service or one of the following kinds of client-driven email services (POP3 / SMTP – common in email services with residential Internet services, IMAP – used as a client-side access method for some Web services or an alternative to POP3 for some residential and small-business services and Microsoft Exchange – used in most larger business setups)
  • your full email address 
  • your password for that email service. For email services that are part of your Internet service, this will be the same as your login parameters for that email service.

POP3 (SMTP) email services

If you are using a POP3 email service, which most consumer and small-business email services are, you will need to go to the email client on your regular computer and make sure the option to “Keep messages on server” is selected. If you regularly work your email from your regular computer as well as your smartphone or tablet, you could set the option to clear messages from the server after a month.

Setting up the smartphone or tablet

You will need to open your email app on the smartphone or tablet and go to “Account” options. In the Android platform, this would be “Email” whereas the iOS devices would know it as “Mail” on the iPhone and iPad.

Touch the “Add Account” function and enter your email address and password. In the case of the Apple devices, you will have an option with the graphics that represent the Web mail services and Exchange service as well as an option for an “other” service. Android users would have to use the Gmail app to work their Gmail account. Where prompted, enter your full email address and password. At that point, enter your name in the “Name” field if you are setting up your Apple device.

Here, the smartphone or tablet will obtain the setup details for your email account and set itself up for that account if you entered in the correct email address and password. This is where Android users would be asked to enter their name, which will appear on the email others receive from them.

If you maintain multiple accounts, you can add these accounts to your device so you can monitor them. This is done using the same procedure.

I would still make sure that any taglines like “Sent from iPhone” or “Sent from Samsung smartphone” are kept so your recipients know that you were replying or sending that message from the smartphone. This may be of concern for people getting used to the touchscreen keyboard on these devices.

Your email application

Android users will find that the arrival of new email is marked by an “envelope” on the top of the screen. They then “draw down” the “blind” which shows a notification screen with any notifications still outstanding. Touch on the “new email” notification so you can see all the new mail that has arrived. As well, the email application will be visible on the first home-screen or the first screen of the “Applications” library screen.

For iOS users will see the email application always at the bottom of the screen alongside the phone application. This will have a red bubble indicating the number of new emails that have arrived.

Tips

What POP3 users need to know

People who use POP3 email services and want to keep a record of an email that they sent may need to send a BCC (blind carbon copy) to themselves of the message because the old POP3 protocol doesn’t allow for proper multi-terminal access to these accounts with a synchronous view.

Similarly, an email that is marked as read or deleted on your smartphone may not be marked as read or deleted on your regular computer and vice versa. This is also to do with the same “single-computer” mentality around this protocol.

Setting your phone up for your Wi-Fi network

It is also a good idea to set your phone or tablet up with your home’s or small-business’s Wi-Fi network so you can make use of the better wireline broadband access plans rather than relying totally on your 3G provider’s tight wireless-broadband tariffs for your email.

Conclusion

Once you have your email set up on your smartphone or tablet device, you can find yourself liberated from your desk when it comes to checking on the arrival of important email.

We can sell the Samsung Android tablets in Australia–for now

Article

Samsung tablet ban lifted | The Age IT (Australia)

My Comments

This latest development is part of the patent war taking place concerning mobile devices, with this round of legal action by Apple against Samsung being more of a “patent on style”. Here, the goal of the Apple lawsuit was to prevent the sale of the Samsung Galaxy tablets and smartphones because they were seen as valid competition to the iPhone and iPad and it has been known that Apple aren’t keen on licensing their patent portfolio to others.

Now the Full Federal Court in Australia overturned an injunction prohibiting the sale of the Galaxy Tab series of tablet devices in in that country; as long as the sales were accounted for. But Apple intends to go to the High Court to maintain an injunction against further sale of these devices

While the initial Federal Court injunction was in place, there were attempts to parallel-import the devices in to Australia but these were met with threatening letters from Apple’s legal team. This is even though it was feasible for people to buy or have others buy the Galaxy Tab devices in other countries that don’t have an injunction in place against them, then bringing them in or having them posted or shipped in to Australia.

This case may have the soundings of similar action that Apple took concerning GUIs and the Macintosh, with it being resolved in a more competitive manner thus allowing for a level playing field.

DLNA in the hotel room

An example of a hotel or serviced apartment block which would be relevant to DLNA

My comments

Why DLNA in the hotel room?

Increased availability of affordable DLNA-compliant entertainment equipment

Most manufacturers who sell consumer electronics are offering electronic entertainment devices that can be connected to a home network and can pull down content from that network or the Internet. When it comes to obtaining media from the home network, these manufacturers will use the established UPnP AV / DLNA technology rather than reinvent the wheel. This feature is being promoted as a distinct product differentiator and will soon end up being offered across all of a manufacturer’s lineup except, perhaps, the very-low-end models.

Some of this equipment is available in form factors that would suit the typical hotel room, suite or serviced apartment. Examples of this include the Sony CMT-MX750Ni / CMT-MX700Ni and the Rotel RCX-1500 music systems that I have reviewed on this site as well as the increasing number of “smart TVs” offered by LG, Samsung, Panasonic and Sony. In the same context, a DLNA-compliant network media adaptor could displace a solution-specific option as the gateway to premium content in the hotel as has been investigated for residential cable TV.

In the case of some of the network media adaptors and “smart TVs”, it could be feasible to integrate site-specific apps or Web links to facilitate interactive services like room-service ordering or in-room checkout that have been part of hotel-based video systems.

Access to online content through mobile computing devices

Most people are making use of online content services like Internet radio, Last.fm, YouTube and Netflix on the mobile computing devices that they take with them all around the world. This also includes use of the Social Web where Facebook and Twitter profiles and pages are replete with photo and video content hosted or referred to by the profile’s / page’s owners.

Multimedia content held on users’ mobile computing devices

Another fact is that guests want to be able to bring their own content. Examples of this include music that is held on a smartphone or reviewing just-taken digital images or footage held on a digital camera or laptop on the large-screen TV.

Acer Iconia Tab A500 tablet computer

Acer Iconia Tab A500 – an Android example of a platform tablet computer

This is being taken further by the fact that platform smartphones and tablets have DLNA controller abilities either with them or as a low-cost or free app; and that mid-range and premium cameras will be equipped with Wi-Fi and “show-on-DLNA” functionality as a product differentiator.

This concept can allow better use of site-specific media like the pay-per-view movies. For example, a movie that is started on the lounge TV in a suite or apartment could be completed on the bedroom TV or a guest could view one of those pay-per-view movies on their iPad or similar tablet.

Personally I also see this concept as part of the desire by the hospitality sector that your hotel room or apartment is your home away from home.

Requirements Of This Setup

Different Media Pools

There are three different media pools that one has to consider when implementing DLNA technology in the hotel environment.

“Own media pool”

This represents the media files that are owned and maintained by the guests. They would be held on secondary storage in a portable computer, mobile device or camera or held on a network-attached-storage device.

Examples of these include music and image collections held on a notebook computer or just-taken digital images and movies held on a camera, camcorder or mobile phone. This could encompass content that is offloaded to a compact NAS device like Thecus’s N0204 “pocket rocket” NAS.

Property-local media pool

This media pool represents all media available to the guests courtesy of the hotel. It would typically be held on servers located within the property and the most obvious application would be those pay-per-view movies that guests can buy and view on their room’s TV.

But it can encompass any “broadcast-to-network” feeds used for distributing regular, cable or satellite TV through the building via the LAN or line-level media feeds used to pipe audio or video content from cabarets, conference suites or similar locations around the hotel.

Global media pool

The global media pool is representative of media that is owned by third parties and held on servers accessible to the hotel via Internet. The guest would simply select the content from the service provider and have it appear on their TV.

Examples of this would include IPTV services; Internet radio; online-media services like catch-up TV,YouTube or Netflix; the Social Web or cloud-driven remote access to one’s home media pool like Skifta.

A distinct logical realm of control

The room or apartment where the guest stays has to be seen as a distinct realm of control for the guest. This also includes situations where two or more rooms or apartments are hired by the one guest to be used effectively as one room, such as the common “connecting rooms” setup.

This means that the guests have to be able to push the media they want to view to any of the DLNA-compliant devices in their room, whether they bring the devices themselves or use the hotel-supplied devices. It also means that they have access to all of the content they can use, whether it’s the media on their laptop, the pay-per-view movies in the hotel or content on their Netflix or YouTube subscription.

But they can’t push the content to neighbouring guests’ TVs without invitation nor can they gain access to content pools they aren’t normally entitled to.

Ericsson’s proof-of-concept solution

This is a “proof-of-concept” setup that works on the assumption that there is no Wi-Fi Internet service in the premises and the mobile device is using wireless-broadband i.e. a 3G data plan for its Internet.

The hotel will need computer equipment on its network that performs the following functions: a Residential Gateway which links the hotel network to the Internet; and a Residential Control Device which controls access to DLNA devices in the guest rooms or apartments.

The guest’s smartphone will need a handler app which is part of the process of establishing the relationship between the mobile devices and the room devices and is performed whether the Internet connection is via Wi-Fi or wireless broadband. This app maps the DLNA equipment in the hotel room to the “global media pool” available through the online media service based on a unique identifier which is generated when the guest checks in for their hotel stay.

This identifier could be obtained by the handler app through a QR or similar code that is shown on the room’s TV screen when the guest enters the room; or printed on the room keycard that the reception staff hand to the guest. A phone capable of working with near-field-communication setups could obtain the identifier through this path, again at checkin or when the guest lets themselves in to their room if the room lock uses NFC technology; such as some of the newer VingCard RFID setups.

Then the handler would list out the DLNA devices in that room as “content sinks” for the guest to enjoy their content on.

Missing Factors

In-house public Wi-Fi

There is a missing factor with the Ericsson proof-of-concept setup. Here, most hotels will want to provide Wi-Fi Internet service as a value-added or extra-cost amenity. As well, all smartphones and tablet computers have integrated Wi-Fi wireless functionality.

The typical way of provisioning Wi-Fi in the hospitality industry is to implement a site-wide public Wi-Fi extended-service-set covering the whole of the building. As well, if the public Wi-Fi network is properly setup, there isn’t the ability to link data between the Wi-Fi-enabled computing devices, so as to assure privacy and security for each computer user. I have raised on this site the idea of evolving this secure-network setup further to allow clusters of device

There hasn’t been work done on the idea of implementing a room-unique or guest-unique network setup for the hotel industry. This is although some hotels were trying out the use of “MiFi” routers to provide guest-unique network setups, which I learnt of in an article in the HotelChatter blog; as well as the many Wi-Fi routers that I had seen set up at the Australian Audio & AV Show in the Melbourne Marriott Hotel in order to provide DLNA media networks for demonstrating network-driven music distribution.

Access to local media

Another missing factor is the ability to provide content that is held in the guest’s own media pool to the room’s DLNA ecosystem. Here, we may want access to the media held on our devices, whether it is music held on a smartphone, videos held on a tablet or just-taken images held on our Ultrabook.

Here, there wasn’t any question about gaining access to media held on these devices via the hotel’s public-access network infrastructure either through “pull” (access through DLNA playback device’s controls) or “push” (source device’s control app) methods.

Multiple rooms

The last factor that wasn’t considered is the desire to pass media between rooms of a cluster such as guestrooms hired by a family or a conference room hired by a business alongside the guestrooms for the conference guests as part of a “block booking”.

These multi-room bookings may provide for arrangements like allowing users to shift the content to other rooms under limited circumstances. Similarly, it could be feasible to have content held on one device in one room viewable on devices in other rooms used by the group.

On the other hand, it would be desireable to prevent content being push-played by one group member to the room of another group member as a way to assure privacy and security for that member.

This situation can be catered for using the Residential Control Device software by allowing bridging between the unique IDs under certain circumstances.

What would be essential for successful DLNA setups in the hotel sector

Local logical network serving one or more physical networks

Here, you would need to create a local subnet (logical network) for each room / apartment or cluster or rooms. The physical Wi-Fi networks that are part of this local subnet would need to work with a unique SSID and stay-unique Primary Shared Key for their security. They would be served by a local Wi-Fi router that would be managed by the hotel’s “back end” software.

This software would bootstrap the router so that it is set up to the guest’s needs and allow guest-supplied equipment to simply and securely enter the subnet, linking it to the Internet and the hotel-supplied DLNA equipment. This would be set up with NFC or QR-Code technology or WPS-PBC setup when the guest enters their room.

Upon checkout, this router would be set up to a “ground-zero” mode which doesn’t provide casual access to the Internet or the DLNA devices until another guest subsequently checks in.

A consistent connection and discovery experience

When you connect your computer equipment to this network, the discovery experience for DLNA-compliant equipment must be the same as for when you use your computer at home.

The local logical network can make this feasible by exposing only the DLNA-compliant AV equipment that exists within the guest room / apartment at the exclusion of equipment and computers in neighbouring rooms. Yet the content-discovery experience is what would be expected for the class of equipment. This includes the use of control points to “push” content to playback devices.

IPv6 – a main facilitator

A major facilitator for this setup would be the use of IPv6 networks. The address pool offered by this standard is much bigger than the address pool offered by the legacy IPv4 technology and there is inherent support for secure tunnels between logical networks.

In this application, an IPv6 setup can comfortably create local logical networks for each and every guest room in a large Vegas-class resort or downtown (central business district) hotel. There is no need to implement network-address-translation to permit the local logical networks and the back-end systems aren’t destabilised. There is the ability for IPv6 routers to create v6-v4 links to legacy IPv4 devices which represent most DLNA media playback devices and this has to be supported and functioning properly in these devices.

Conclusion

What needs to happen to facilitate the concept of DLNA-based media management in the hotel environment is for further research and study to take place. Here, it would need to be based on technologies that are currently available to the hotelier and potential guests, such as in-house public Wi-Fi networks and near-field communications.

The functionality could also be implemented in network-infrastructure equipment through the use of software that is deployed to the equipment while it is in use, rather than through replacing or adding new hardware. Any DLNA-enablement setup should not preclude the use of media devices that are available to the consumer marketplace.

Bluetooth Smart–What does it mean for Bluetooth devices

Article – from the horse’s mouth

Bluetooth SIG – "Bluetooth Smart"

My Comments

Bluetooth 4.0 Low Power technology, formerly known as Wibree technology has been put on the market this year. This technology is pitched more for “sensor/controller” devices that primarily provide data to another device; and are required to run for a long time on two AA batteries or a “button-style” battery. Examples of these devices include watches, heart-rate monitors, shoe-attached pedometers, door-window security sensors and the like.

These devices are being marketed as Bluetooth Smart devices and Bluetooth terminals like smartphones and computers that can work with these devices are marketed as Bluetooth Smart Ready devices.

A Bluetooth Smart device like the heart-rate monitor or door security sensor has to be compliant to Bluetooth 4.0 Low Power as a single-mode device and support GATT functionality. These devices cannot work with legacy Bluetooth devices that don’t support this standard.

Bluetooth Smart Ready is used to describe a Bluetooth device, typically a “hub” device like a computer or smartphone that works with these Bluetooth Smart devices. The Bluetooth Smart Ready device must have Bluetooth 4.0 enablement with GATT support. It also has to have a dual-mode low-energy Bluetooth transceiver and updatable software. This would typically benefit regular and mobile/embedded computing devices that work to a “platform” like Windows, MacOS X, iOS or Android. These devices can connect to the Bluetooth Smart devices as well as regular Bluetooth devices.

At the moment Apple has the Smart Ready devices  in the form of the iPhone 4S and the latest iterations of the MacBook AIr and Mac Mini computers. But this technology will be rolled out in to newer computers and Bluetooth modules. The Bluetooth Smart technology will be a point of innovation as companies develop the sensor devices and software for this newer hardware platform.

I would also see this as an improvement for Bluetooth keyboards, mice and controllers due to the idea of having these devices run on a pair of AA batteries that assure reliable operation for a long time without needing to be charged frequently.

It will open up the Bluetooth universe to a larger collection of devices, services and applications that most of us wouldn’t have thought of.

Using your smartphone or tablet with your network-attached storage

Why use your smartphone or tablet with your NAS

There are times when you want to upload or download files from your network-attached storage device using your smartphone or tablet computer. Examples of this include offloading files from a low-capacity device, through making media that you took or acquired through your device available at all times from your DLNA-equipped NAS to simply backing up data held on your device.

Of course, you may simply treat that NAS simply as a network transfer point for your data. Examples of this may include working with documents that you start on an iPad and want to complete on your regular computer or conceptual “rough-shot” pictures that you take you your phone’s camera and want to work with further using Photoshop and other software on your computer.

How is it done

But how am I able to do this with my network-attached storage and my mobile devices? Some network-attached storage devices may use a Web front for the file collections where as others may implement certain extensions to DLNA for uploading and downloading some media files. This latter situation is infact a long-term goal for the DLNA Home Media Network, especially when it comes to shifting or syncing multimedia files like music or images.

These environments don’t necessarily provide a consistent or ideal user experience for the mobile device user. This can typically be due to a Web front that is optimised for desktop use only to DLNA server and client apps not offering the proper sync or file-transfer functionality.

SMB file-manager apps

The preferred method that I would use is SMB/CIFS network file handling which every network-attached storage device supports thanks to Linux’s SAMBA software. Even the USB-linked file servers that are an increasing part of high-end routers like the Freebox units do support SMB as well as the Internet HTTP and FTP file transfer protocols. This has been a standard for regular computing devices with the Microsoft Windows Platform since Windows For Workgroups 3.11, then was exposed to Linux regular computers through SAMBA and has been exposed to the Apple Macintosh platform since MacOS X.

The platform-based mobile devices now can join the SMB party through the use of SMB-enabled file-manager apps. These are typically low-cost or free apps that expose the mobile device’s file system and the SMB file shares (entry points) made available by computers or network-attached storages. Some of them have file-viewer functionality for file types not supported by your device’s file handlers.

The various app stores for the popular mobile-device platforms will list more of the file manager apps with SMB file transfer and you can find them using the terms “SMB file transfer” in your search query.

It is also worth noting that your NAS’s vendor may offer file-transfer apps for their device on the iOS and/or Android platforms so you can transfer the files to their device. These programs may also work with the remote-access functionality that some of the consumer and SMB NAS units provide, thus keeping login credentials for the devices and streamlining the remote-access experience.

Other issues worth highlighting

iTunes-purchased content

You may have problems copying content that you purchased with iTunes on your iPhone or iPad directly to the NAS due to Apple’s setup for these devices. But they have improved the iTunes and iOS setup to allow a user to download the purchased content to an instance of iTunes run on a regular computer even though they purchased it on the iOS device. This works best if the regular computer’s iTunes library is referencing the NAS in question.

People who use iOS platform devices that aren’t updated to iOS 5 will need to tether the device to their iTunes-enabled regular computer. Then they will need to use the “Transfer Purchased Content” option in iTunes to copy the content they bought on the device to the regular computer or NAS.

It will also be important to make sure that audio content is downloaded as MP3 files rather than protected M4A files.

One way that Apple can work this situation out better is to implement read-write ability to iTunes (DAAP) servers for the iPod media-management app in their iOS platform. Here, the software could then support improved “offload” functionality. This may not come about due to Apple’s investment in and their fanbois’ preference for the iCloud as a large-capacity storage service.  But practically-minded Apple enthusiasts could place more value on a NAS as an extra-capacity data store so they know where their iTunes content is all the time.

File-transfer operating conditions

When you transfer files between your mobile devices and the NAS, make sure that you have a strong Wi-Fi signal at your mobile device and that the device has sufficient battery strength. This could be achieved through having the device connected to its charger while the transfer goes ahead.

NAS setup conditions

If you are transferring media files to the NAS, you would need to transfer them to the media folders that are referenced by the media-server software on that device. This may be made easier by using the file manager software’s “bookmark” or “favourites” options to point to the start of the NAS’s media folder tree.

It is also worth keeping other personal and workgroup shares on the NAS simply for backup or transfer purposes and referencing these with your file-manager app.

Conclusion

Once you are able to know that you can use the SMB file transfer method for moving data between your NAS, tablet and smartphone, you can see more value out of these mobile-computing devices.

Apple iOS 5 to be updated without the need to tether your device

My Comments

Now the iOS 5 has been released, it will offer some major benefits for your iPhone or iPad. You will have to tether your iPhone, iPod Touch or iPad to your computer to update it to the new version but this will be the last time you need to tether the device according to Apple.

Here, you will have the operating-system updates able to be downloaded over the air using the same method as what is used for delivering and updating the apps for your device. Newly-deployed iOS devices will not need a computer to be present as part of their setup process anymore.

As well, if your iDevice is charging and the computer that hosts your device’s parent iTunes collection is on, the device will be synced over the home network. This is something that has been offered by competing mobile platforms with their desktop software.

There are some benefits like improved operation for some of the integrated apps. This also includes a “notifications” screen similar to what Android users have had; as well as an integrated Twitter client. Of course it supports an iP messaging service that works between Apple iOS devices and I am not sure if there are clients for the desktop operating systems.

As well, I detailed on a speech-driven agent app called Siri which interacts with the iOS 5 devices by responding to your spoken requests. This function has been promoted in relation to the iPhone 4S smartphone.

There are a few functions that the competing mobile platforms still have an advantage over the Apple iOS platform. One is the provision of always-displayed screen items that programmatically change or act as a user interface to a program. These are in the form of “widgets” and “live wallpaper” in the Android platform and “tiles” in the Windows Phone 7 platform; and could show running data like time, weather or stock-market data. The Apple platform only allows apps to attach a “bubble” to their screen icon that can show a number or a “traffic-light” colour to show certain events; and this has severe limitations. For example, you can’t control or monitor multiple devices or functions using a single monitor app. This could be something that could be rolled out in a subsequent major update for the iOS platform.

At least this operating system will be a major break for your iOS device by offering it a lot more.
