Bluetooth is now seen as legitimate for air travel

There is a strong question about how you should be using Bluetooth headsets and the Bluetooth functionality of your smartphones, laptops and tablets when you are flying.

The key drivers for Bluetooth in the airliner cabin are:

• Bluetooth headsets and earbuds with active noise cancelling functionality being increasingly popular
• Bluetooth earbuds and an increasing number of mobile devices not supporting wired audio connectivity
• A significant number of travel-friendly Bluetooth transmit adaptors appearing on the market with a use case being to use Bluetooth ANC earbuds with in-flight entertainment systems
• An increasing number of avionics (aviation-use electronics) manufacturers like Panasonic are offering in-flight entertainment systems that are designed to work with passenger-supplied Bluetooth headsets. This allows for passengers to enjoy in-flight entertainment content with their favourite headsets, especially as they have a wide choice of good-quality active-noise-cancelling headsets and earbuds at good value for money.

As well, aeroplane and avionics-system manufacturers are designing their aircraft and equipment for Bluetooth / Wi-Fi resilience so this technology doesn’t cause problems with aeronautical navigation or aviation safety.

The questions that will still remain are whether you can use your Bluetooth headphones in flight and whether you can use them through all of the flight or just when the plane is cruising at altitude. But the consensus that seems to have been worked out amongst civil aviation authorities, IATA (who represent airlines) and most airlines is to limit Bluetooth use to when the plane is cruising. Some airlines may permit the use of Bluetooth setups during take-off and landing.

You also may know that the aeroplane mode or flight mode for your smartphone, tablet or laptop may be primarily about disabling the cellular modem functionality for devices so equipped. This is so the cellular modem doesn’t “hunt” for mobile base stations which are on the ground while you are flying, thus interfering with radio-based air-navigation setups.

Here, if your device is in that mode, you may have the option to selectively enable Bluetooth or Wi-Fi depending on the circumstances such as to use Wi-Fi-based in-flight connectivity. These modes are primarily about short-range radio connectivity rather than long-range connectivity.

.. especially in the context of ANC-capable Bluetooth headsets like the Sony WH-1000XM4 headset

As well, if your phone and your headset has a wired-audio connection, typically a 3.5mm audio jack or audio via USB-C or MFi Lightning typically facilitated by an adaptor of some sort, this would be your fallback if you aren’t sure. It would apply to the traditional-designed over-ear headsets like the Bose or Sony ones because these would have an audio input jack that works with a cable for wired-audio connections.

If you are unsure about this, it may be worth asking the cabin crew about the policy that is in place for Bluetooth-capable headset setups in the plane. They may advise you on information that may pertain to the aircraft you are flying on.

What to watch out for

A technology to watch out for is Bluetooth LE Audio and Auracast being implemented within the aircraft cabin. This is a “next-generation” Bluetooth audio standard which supports efficient audio streaming which leads to battery efficiency for mobile devices and headsets while yielding high-quality sound; as well as Auracast which is about broadcasting audio content using Bluetooth LE technology.

Bluetooth LE Audio and Auracast will be driven by the use of bearing-assistance devices (hearing aids and cochlear implants), along with true-wireless-stereo earbuds. This is because of the efficiency that is part of the design and the ability to implement true wireless stereo from the source in a heterogenous manner.

Airlines will need to be aware of Bluetooth LE Audio as an upcoming passenger infotainment technology. This is expected to become ubiquitous over the next few years with headsets and audio-capable devices to be equipped with chipsets offering dual-mode (Bluetooth Classic Audio and Bluetooth LE Audio) operation for best-case operation.

A key feature that will benefit this industry is Auracast broadcast audio. Here, this could be about support for multilingual flight-safety briefings where you only hear your language, audio environments where you hear your device’s multimedia entertainment but not miss the announcements as they come through the PA system nor lose out on the active-noise-cancelling your headset would offer.

In the case of flight-safety briefings augmented with audio or video content, there could be the ability to have concurrent multilingual audio where the passenger has the choice of which language they hear. This would avoid that repetition of the same message in different languages which can be a bane for frequent travellers.

As well, Bluetooth LE Audio and Auracast, with its relevance for people who are hard-of-hearing may increase the legitimacy of Bluetooth audio usage during all phases of a flight. Here, this would be about raising the technology to the level of an accessibility measure thus considering its increased use during flights.

Conclusion

What is being realised is that Bluetooth in the context of headsets is being seen as a legitimate in-flight connectivity technology especially when it comes to entertainment whether from your device or the in-flight entertainment setup.

Marantz’s new streaming CD player and stereo amplifier are TV and turntable-friendly | What Hi-Fi? (whathifi.com)

From the horse’s mouth

Marantz

CD-50n Network CD player (Product Page)

My Comments

The last decade has seen the traditional vinyl record gaining a revival as a preferred physical medium to collect recorded music on. But the CD, which has just turned 40 this year, has been simmering along as a collectable music format over this same period and is gaining a similar kind of recognition and acceptability to vinyl.

Some of us still use CD as our preferred physical music medium due to it being cheap on the new or secondhand market or easy to have in a mobile or portable form such as through ripping to hard disk and syncing to our smartphones. As well, the small size of these discs appeals to those of us who want to build or maintain large collections without it taking up much space. Even the record labels have exploited this further by justifying CD as a medium to offer collectable album editions that hold more musical content than the standard album editions, perhaps due to a disc holding extra material or multi-disc compilations stored in a case that is the same size as the standard CD jewel case.

Are we still playing CDs nowadays

This has been more so due to CDs being a cheaper format to replicate and sell than vinyl although able to yield a very-high-quality sound. As well, more of the premium hi-fi brands of respect are giving CD as much developmental and promotional space as vinyl, with this manifesting in component-type CD players that you connect to your hi-fi system appearing in more audio product lineups. Even Yamaha has reintroduced the 5-disc CD changer where all the discs are loaded on to a carousel that is part of a large drawer, in the form of the CD-C603 changer. As well, some consumer-electronics manufacturers are still persisting with CD receivers or stereo systems that play CDs with the former being a component that has radio, CD and, perhaps, network / Internet audio sources which you just connect to a set of speakers of your choice.

I have covered on this site some of the “network CD players” that Yamaha, Marantz and Technics have launched over the years. These combine a CD player and a network-audio streamer in one box, only requiring you to use one input on your amplifier or receiver to play CDs or content held on online sources or your home network.

Marantz have solidified  their position in the network-CD-player space in two ways. Firstly they have released a network SACD player in the form of the SACD-30n with similar features but omitting the HDMI ARC connection. But this time they have released the CD-50n network CD player which follows on from the ND-8006 network CD player that I covered previously.

The Marantz  CD-50n is a CD player with the expectations of a current premium full-width component-type CD player. This includes a mechanism and signal path that is engineered for high-quality CD reproduction and the same kind of advanced CD play functions associated with that format for a long time.

This unit even underscores the “single input on the amplifier” advantage associated with network CD players further by being equipped with an HDMI-ARC connection for TV audio. Here, you would connect the Marantz CD-50n to your TV’s HDMI-ARC connection so you can have the TV’s sound play through your hi-fi system.

Of course, there are the coaxial and optical SP/DIF inputs and outputs that make this unit work as a digital-analogue converter for TVs, MiniDisc decks or other digital-audio equipment; or pass the sound in a digital-audio manner to a digital amplifier or DAC. You can use this network CD player to stream audio content from smartphones and similar Bluetooth-capable devices through it to the connected sound system.

The Marantz CD-50n works as a sound card for computers that are connected to it via USB but some Windows computers will need to run a Marantz-supplied driver to work properly with it. As well, there is a USB Type-A connection for a Mass-Storage device that is full of music held in the common audio file formats.

As mentioned previously, this Marantz network CD player can connect to a digital amplifier or DAC via an SP/DIF optical or coaxial connection. There are two line-level outputs, represented as two sets of RCA sockets on the back. One of these is a fixed-level output typically used with most stereo systems where you have an amplifier that you regulate the sound level with while the other is a variable-level output that can he used with a power amplifier or active speakers. This also comes in to its own in other use cases where you expect the Marantz unit and its remote to be the point of control for the sound level.

There is a built-in headphone amplifier so you can connect a pair of wired headphones to the Marantz CD-50n. But it can serve as a Bluetooth source device where you use a pair of Bluetooth headphones or a Bluetooth speaker as the audio output device. In this case, you have to use the Bluetooth device’s volume control to adjust the sound volume to your tastes. The Bluetooth functionality for both source and target device roles works according to the Bluetooth Classic specification.

As far as your home network is concerned, you can connected to it via Ethernet or Wi-Fi. This leads you to it being part of the DLNA Home Media Network where you can play content held on a media server or NAS. Or through the Denon/Marantz HEOS platform, you can stream a variety of online services like Spotify, Deezer or Tidal, managing them from your smartphone with the HEOS app. For Internet radio, the HEOS platform has support for the TuneIn Internet radio platform so you can listen to a wide range of radio stations including from overseas through the Marantz CD-50n.

Being part of the Denon/Marantz HEOS ecosystem also means that the Marantz CD-50n can work as part of a network multiroom system using other HEOS-capable wireless speakers or hi-fi / AV components made by brands in the Denon-Marantz group. As well, it can be part of the Apple AirPlay 2 or Roon network-audio ecosystems, especially the latter which is seen as the “audiophile network multiroom audio” standard.

If you have a recent Marantz amplifier with the appropriate connections, the CD-50n can be connected using Marantz’s proprietary inter-component control arrangement. This will open up the possibility of single-remote-control operation, one-touch start-up and one-touch shut-down operation.

This player costs AUD$3200 in Australia, but you have a highly-strung CD player and network-audio streamer in one box which may seem to justify the price when you are in to premium hi-fi. Personally, I would like to see more hi-fi companies keep at least one of these network CD players in their product range for those of us who want that single-box solution to a digital audio source in our audio systems.

LG SoundPop 360 Bluetooth speakers
– an example of the popular Bluetooth speakers

A very popular accessory for smartphones, tablets and laptops is the Bluetooth speaker. These speakers connect to your mobile device via Bluetooth and work as an audio output device for it.

The typical design for most of these speakers is to be a highly portable battery-operated unit that can fill a small area with sound in a manner equivalent to the typical portable radio. These appear in many different sizes from something that fits in your palm to larger tube-shaped units that can be carried using a strap or shoved in your coat pocket. Add to this an increasing number of larger cube-shaped speakers that put out a bass rich sound.

Add to this larger mains-powered bookshelf active speakers that have Bluetooth audio functionality in them along with a variety of inputs like analogue line-level and phono inputs or USB, SP/DIF and HDMI digital-audio inputs. These are being pitched as a way to set up a stereo for an office or small apartment.

In a lot of cases especially with portable speakers, these have a built-in microphone so they can become a speakerphone for your mobile device, something that can come in handy for conference calling including Zoom calls. But some Bluetooth speakers like the B&O Beosound A1 2nd Generation speaker even have this function set up so they work with your smartphone or tablet as a voice-activated smart speaker.

hese exist in a universe of Bluetooth audio endpoints like audio adaptors that work between a line-level audio connection and Bluetooth Classic audio as either a transmitter or receiver. This is in addition to home audio equipment receiving Bluetooth audio as an input and/or transmitting content available to it as a Bluetooth audio stream.

An example of this is in the form of portable and mantel radios that work as Bluetooth speakers. This device class has capitalised on the interest over the last 15 years in premium radios thanks to the likes of Bose and Tivoli offering radios that look and perform “above average”; the nostalgia for vintage-styled radios, along with broadcast radio being delivered via digital-broadcast technology or Internet technology and yielding programming exclusive to those technologies.

It includes companies offering audio source devices like turntables or CD players that stream to Bluetooth speakers. This is because the Bluetooth audio specifications are in fact “application-level” specifications that have been pre-determined for a long time, so there as surety that their source devices can work with any Bluetooth audio endpoint device. Here, it could allow someone to create an elementary sound system around that device and a pair of Bluetooth speakers.

Some of these speakers come with other features like LED-driven “party lights” or very large batteries that work as powerbanks for charging mobile devices. As well, a lot of larger portable Bluetooth speakers make use of passive radiators as a way to increase their bass response while others rely on an app-driven approach to allow you to adjust their sound quality from your smartphone.

Multi-speaker operation

But, thanks to Bluetooth 5, there has been an interest in multi-speaker Bluetooth audio approaches. This comes in the form of two operating modes:

Party Mode: Multiple speakers play the same programme content from the same source device with speakers that are stereo-designed playing the content in stereo across the speakers in that same box. This is to provide more sound coverage, typically for entertaining people at a party. Most such setups can handle a relatively large number of speakers due to latency not being considered important for this use case.

Stereo Mode: A pair of like speakers are set up so that one plays the left channel of a stereo programme source from one source device while the other plays the right channel of that same source. This is to improve the channel separation for the stereo content.

Typically manufacturers are limiting this functionality to a subset of their Bluetooth-speaker product range, more so the products in the “value” and “premium” market positionings.

These operating modes may work in one of two arrangements;

Source-to-speakers / hub-and-spoke: The source device streams the audio content to the speakers at once. This is typically implemented for stereo-mode operation so as to reduce latency by making sure the data gets to each speaker without any middleman device processing it.

Speaker-to-speaker / daisy-chain: The source device streams the audio content to one speaker which passes it on to other speakers down the line. This appeals to party-mode operation so as to permit large numbers of speakers to be in the setup. It may allow speakers to introduce some latency but this isn’t an issue for party-mode operation due to the goal of covering a large area with sound.

What to watch

Bluetooth LE Audio and its impact on Bluetooth speakers

Bluetooth LE Audio has been cemented in stone as the next-generation Bluetooth multimedia audio standard and is expected to provide a raft of improvements for this device class.

This implements the Bluetooth LC3 audio codec which is about efficient audio data transfer and even improve sound quality, operational stability and battery runtime. Here it also allows mobile-technology designers to avoid reinventing the wheel for audio-codec improvements when it comes to baseline audio performance for Bluetooth audio.

For portable Bluetooth speakers, this could be about allowing you to move around more freely with your mobile device without fear of losing the music as well as being able to run for a long time before needing to be charged up. As well, there will be the ability for these speakers and similar devices to cope with congested 2.4GHx wireless environments like in a city centre because of the robustness that the LC3 audio codec will offer.

This could impact how they are designed such as to have portable speakers that are lighter because of not needing to design around large battery packs. There will also be the chance to design higher-quality portable Bluetooth speakers that take advantage of higher quality sound that the new codec offers. Multi-speaker setups, especially based on Auracast, could be benefitting if the setup permits meshed or daisy-chained operation because of reduced latency in such setups and less impact on battery runtime for the actual sound reproduction.

Auracast broadcast audio will come in to its own with Bluetooth speakers that implement the Bluetooth LE Audio standard. Firstly, this could be about multiple-speaker party-mode operation without a requirement to use particular speakers from the same manufacturer. It may even allow the use of multichannel setups within the same Auracast multi-speaker setup rather than having “party mode” or “stereo mode” being mutually exclusive. Here, you would be using “audio sharing” on your phone, tablet or laptop to facilitate this mode with the device being enabled for Bluetooth LE Audio and Auracast.

As well, Auracast-based broadcast audio and Bluetooth speakers can be a perfect partner here. For example, a small Bluetooth speaker used in this context could be about close listening to an alternative soundtrack for video or other content or following an event going on in a nieghbouring area from another small room where you might be engaging in activity relating to that event.

Similarly, Auracast with Bluetooth speakers could be a logical follow-on to FM radio where listenership using BYO audio devices is desired for an event hosted in an area with a small footprint.

Previously, radio broadcasters were often collaborating with event organisers to broadcast the musical soundtrack to a large public event like a fireworks display, street parade or motorcade. Then you would have to bring a portable radio to that event and tune in to that station to follow the soundtrack using that radio to get the best value from that event. This approach may be seen as irrelevant for a radio station with a large broadcast area like a major city’s metropolitan area unless the event has a large footprint that takes in more of that broadcast area such as a fireworks display encompassing a waterway that passes through the city.

Similarly, there were the drive-in cinemas where you tuned your car radio to a particular frequency to hear the film’s soundtrack. Here, this was limited to what the FM band was about and issues like destructive multipath that could ruin your listening experience.

Here, Auracast could lead towards a license-free wireless audio distribution approach centred around Bluetooth speakers that implement Bluetooth LE Audio technology. It would also be about increased flexibility within the setup like multichannel speaker clusters (think stereo pairs or speakers plus subwoofer setups).

The Bluetooth LE Audio specification will also impact multiple-input operation for Bluetooth speakers. This could be about seamless multipoint operation when you want to use a speaker with a smartphone and laptop or allowing your party guests to contribute to the music at your party using their devices. It could also be about party speakers that work with Bluetooth LE Audio microphones for karaoke and PA usage.

How Bluetooth LE Audio will come in to play for devices like Bluetooth headsets and speakers is the availability of dual-mode system-on-chip circuitry for this class of device. This will allow devices to work in a Bluetooth LE Audio or Bluetooth Classic Audio mode depending on what Bluetooth device they are working with, so as to assure maximum compatibility.

What could be done

There could be an emphasis towards optimising for and promoting mesh operation within multiple-speaker setups. Here, it can be used to make these setups more robust including allowing you to position your smartphone or other source device near any of the member speakers to assure audio continuity.

Multi-speaker setups could also be about bass improvement such as to add a subwoofer in to a party-mode or stereo-mode setup to pump up the bass. This also includes use of speakers that implement separately-amplified bass drivers being capable of working as part of these setups, especially “stereo-mode” setups.

There could be less reliance on “app-cessory” operation for common advanced functionality like tone control or lighting control. This could be facilitated with application-level functionality in Bluetooth LE Audio for these functions and avoid the need to create buggy apps for mobile and desktop platforms.

Manufacturers could look towards offering a variant of their Bluetooth speaker designs that has a broadcast-band radio tuner built in. Here, if you had already bought a particular speaker and then know there is one of the same design as what you already bought but has the radio functionality as well, you could justify buying the one with the radio so you can have a pair of speakers for party-mode or stereo-mode operation. It could also incentivise the manufacturer to design the speakers to work in multi-speaker mode for radio broadcasts as well as your phone’s audio.

It could extend to Bluetooth speakers that have line-input connections being able to stream the device connected to that input across a multi-speaker setup. This would extend the utility of that connection for multi-channel setups or party-mode setups.

Other complementary standards could be worked on to bring more utility out of the Bluetooth speaker class. For example, the HDMI-ARC standard could be worked on in a manner to support delivery of multiple soundtracks for the same video content. Here, this could incentivise the development of soundbars and AV receivers that allow streaming of different soundtracks to Bluetooth audio endpoints associated with the same device. That could allow a viewer to hear an alternate-language or audio-described soundtrack for video content using a Bluetooth headset or speaker paired to the soundbar or AV receiver while others hear the main soundtrack for that same content through that soundbar.

What I see that will affect Bluetooth speakers is the next few model cycles is to have Bluetooth LE Audio support as a heavily-marketed feature that will improve how they operate in many ways. It is something that I would see drip through a manufacturer’s Bluetooth audio product range.

Introduction

I am reviewing the Brother PT-P910BT Bluetooth label printer that uses USB-C or Bluetooth host-device connectivity to print out labels using Brother’s TZe family of label tapes. This means it doesn’t use your home network for this purpose, rather it uses local peripheral connectivity approaches.

The Brother PT-P910BT Bluetooth label printer

The Brother PT-P910BT Bluetooth label printer is similar to the PT-P710BT label printer that I have previously reviewed. Here, these devices work on an USB power or a user-replaceable battery pack installed within the unit. They talk to the host computing device via a USB or Bluetooth connection working in a similar vein to a direct-connected printer.

They are dependent on Brother’s P-Touch software for regular Windows or Mac computers or the iPrint&Label for iOS and Android mobile-platform devices. As well, the use Brother’s TZe cartridge-based direct-thermal tape platform.

This can use the 36mm TZe label tapes that are wider

But the similarities stop here. The PT-P910BT which is finished in white is capable of working with TZe label cartridges that use 36mm-wide tape in addition to the narrower label tapes. That is compared to the PT-P710BT using label tapes with a maximum width of 24mm. Even if it appears to be thicker to accommodate wider tape, the Brother PT-P910BT label printer can be laid flat or be stood upright.

Uses a USB-C socket for data connectivity or power charging

The PT-P710BT label printer used a USB micro-B port as the equipment-side connection. But the PT-P910BT label printer implements the USB-C port as the equipment-side connector and is furnished with a USB-C to USB-A cable so you can connect it to regular computers or USB chargers using the traditional USB-A fitting.

Here, it has become the first Brother label printer that I have had for review that uses a USB-C connection for charging or wired connection to host computing devices.

Setup

Setting the Brother PT-P910BT label printer up with a mobile-platform device was simple. Here, you held down the power switch until the light flashed to make the printer discoverable by the mobile device, then you had to use iOS or Android to pair the printer to your smartphone or tablet.

This can connect directly to your USB-C-equipped Android smartphone using a USB-C cable. You have to select USB as the connection type on iPrint&Scan in this case.

After that, I had to make sure that Brother’s iPrint&Label Android software was downloaded from Google’s Play Store and installed on my Android smartphone. I also tried connecting the Brother PT-P910BT Bluetooth label printer to my Samsung Galaxy S8 Plus Android smartphone using a USB-C to USB-C cable and used the same iPrint&Label app to make a label using this connection. This was feasible once I tapped on the device name and then selected USB as the connection type to use within the same app.

For your Windows computer, you had to download then install the Brother P-Touch software, with an installation step having you connect the printer to your computer via USB. The Bluetooth setup process became awkward at some point because the Brother software invoked Windows and failed to discover even when the printer was in Bluetooth-discovery mode and the computer could “hunt” for Bluetooth devices.

Use

Once set up, the Brother PT-P910BT Bluetooth label printer was able to turn out labels very quickly and clearly. It

But it still works as a Bluetooth labeller

didn’t matter whether were working with the P-Touch Editor on Windows or iPrint&Label on Android.

The printer can work with two Bluetooth-connected host devices concurrently but you will need to wait until it has finished printing before you can submit your label job from the other device.

The single light can be very confusing when it comes to knowing whether the unit is on an active Bluetooth connection or not, or if there is enough power in the battery. There is a second light near the USB socket to indicate whether it is charging or not. Personally, I would like to see a steady blue light glow during a Bluetooth connection and flash while it is in discoverable (pairing) mode as a way to make Bluetooth setup easier.

Limitations and Points of improvement

The Windows driver software needs to adopt a simplified setup approach that is agnostic of whether the device is connected to the host computer via USB or Bluetooth. It could allow you to install all the software then begin the Bluetooth pair-up process using the Find New Device option in Windows 10’s Settings menu.

As well, it will also be of concern for those of us who switch between USB wired and Bluetooth wireless connectivity on a whim. This may be to allow a user who forgot to charge the Brother P-Touch Bluetooth label printer up before doing a labelling run to connect to the host computer via USB for that job with that computer powering the labeller. This is even though the user uses Bluetooth as a preferred connection for their setup.

Brother could also set a good example for USB-C peripheral devices like labellers by fully implementing USB Power Delivery for charging or powering these devices. This could allow for fast-charging using ordinary USB PD hardware, like what is being expected for Android phones.

Conclusion – Is it a tool or toy?

This is an example of Brother offering an incremental update for a P-Touch labelling product and offering it as an updated variant that works with the largest of the TZe tape sizes. Again, this Brother PT-P910BT labeller comes across as a tool especially when you are wanting to do any labelling “on the go” while you are using

It is more about taking an incremental approach to improving and updating products rather than taking a radical new design approach. But the Brother PT-P910BT underscores the idea of using your smartphone or tablet and its Bluetooth connectivity or USB connectivity in the case of recent Android USB-C-equipped smartphones to turn out labels.

Google Fast Play could open up an improved point-to-point data transfer experience to Android smartphones

Google working on ‘Fast Share,’ Android Beam replacement and AirDrop competitor [Gallery] | 9To5Google.com

Fast Share is Google’s Android Beam replacement: Here’s what you should know | Android Authority

My Comments

Google is to provide as part of the Android platform a new “open-frame” point-to-point data-transfer solution. This solution, known as Fast Share, implements Bluetooth and peer-to-peer Wi-Fi to transfer text, pictures, Weblinks and other resources.

The Android platform had two different peer-to-peer data-transfer solutions previously. The first of these was the Bluetooth profile that was implemented by Symbian, Microsoft and others to transfer pictures, contact details and the like since the rise of the feature phone. The second of these was the Android Beam which used NFC “touch-and-go” as a discovery method and initially used Bluetooth but moved towards peer-to-peer Wi-Fi as a transfer method.

This was while Apple was using AirDrop across their ecosystem which included iPhones and iPads. In Apple’s true style, it was part of keeping as many users on the iOS platform and you couldn’t do things like transfer to other mobile or desktop platforms.

Google is intending to have Fast Share as part of their Play Services software package rather than being “baked in” to a particular version of the Android operating system. Here, Fast Share can be run with Android devices running older versions of the operating system which is a reality with a significant number of phones where the manufacturer won’t provide support for newer Android versions on particular models.

Advance images of this concept shown on the Web are underscoring a tentative plan to port it to their own ChromeOS and Apple’s iOS operating systems. If Microsoft and Apple are interested, it may be seen as a way for Windows or MacOS regular-computer users to share resources across the room on an ad-hoc basis. As well, Google could look at how Fast Share can be implemented in a “headless” form whether for sending or receiving the data.

You will have the ability to share file-based resources like photos, videos, PDFs or vCard-based contact-information files along with URLs pointing to Web-hosted resources or snippets of text. This will satisfy most usage requirements like sharing family snapshots, contact details or Weblinks.

There will be the option to give a sender “preferred visibility” status so they can discover your phone when you are near them. This status means that they will see your device if you aren’t running the Fast Share app. Of course, users can turn Fast Share on and off as required, preferably with the idea of turning it off when using the phone in a public place unless they expect to receive something. You also have the ability to decline or accept incoming files so you have some control over what you receive.

The core issue with Google Fast Share and similar point-to-point across-the-room file-transfer platforms is that they have to work in a truly cross-platform manner so you don’t have to worry whether your friend sitting in that armchair across from you is using an iPhone or Android device when you intend to send that photo to them or share your contact details.

Pure Sensia 200D Connect Internet radio – a representative of the current trend towards the “hybrid radio” concept

Previously, I have covered the concept of “hybrid radio” which is being put forward by RadioDNS. This is about integrating the reception of audio-based radio content from a radio station either through the traditional analogue or digital broadcast technologies or through the Internet.

It is based on the common Internet-radio application where traditional radio stations transmit a simulcast of their broadcast output as an Internet stream. You would experience this with an app like TuneIn Radio or by using an Internet radio, of which I have reviewed many. This has been used to listen to overseas radio stations by those of us who like the “vibe” of a particular country or to learn a new language, but has been used as a way to hear a national radio station that isn’t received in one’s local area, a situation that is common in rural Australia.

It is intended to provide automatic switching to an Internet-based simulcast of the radio station if you are out of the reception area for a broadcast transmitter and you can’t be “handed over” to a better transmitter’s output of the same station. It is also underscored by the concept of a “single-dial” tuning approach to select stations without worrying which broadcast methodology they are using, whether traditional or Internet-based. here is also the availability of richer metadata that can be shown on screens that support rich graphic displays along with an electronic programme guide for radio broadcasts.

This functionality is dependent on the radio having Internet connectivity of some sort. It is typically with the set being equipped with Wi-Fi or Ethernet connectivity for use on a small network, or a car radio being equipped with a mobile-broadband modem provisioned with mobile-broadband service.

This may not work properly with enterprise or public-access networks that require authentication beyond a Wi-Fi passphrase or WPS-PBC setup or we have to make sure the mobile-broadband service is provisioned for the car radio that we are using in the way the radio expects. This was something I had come across when someone posted a question about attempting to use the Internet capabilities of the Sony CMT-MX750Ni Internet-capable bookshelf music stereo system with a “headline” public-access Wi-Fi network in the place they were living in.

As well, the Internet connectivity is offered by consumer-electronics manufacturers as a product differentiator with it typically ending up on the premium products in the range. Similarly, some manufacturers want to steer clear of Internet-connectivity as a feature for their consumer-electronics product ranges.

But an increasing number of radio sets and audio equipment are implementing Bluetooth technology typically to allow streaming of audio content from mobile devices paired with the set. In the car-audio scene, this is to facilitate a safe hands-free telephone setup that allows the driver to keep their hands on the wheel and eyes on the road.

Smartphones or tablets could be used to provide “hybrid-radio” functionality

The RadioDNS hybrid-radio concept could be extended to the Bluetooth link by a standard application-level class or profile for the Bluetooth specification. Here, this would work in conjunction with a computing device that runs companion “hybrid-radio” software and is linked to the radio via Bluetooth in order to enable full “hybrid-radio” functionality.

This could allow for broadcast station selection using the companion device or the display of rich metadata for the currently-listened-to station on the companion device’s display irrespective of the source of the metadata. This would be of benefit to those sets that can’t show rich graphic metadata such as what DAB+ or Digital Radio Mondiale are capable of.

The concept cam make use of the voice-driven home assistants like Amazon Echo or Google Home for many options. Here, it would exploit the idea of having a device like Amazon Echo or Google Home provide the Bluetooth – Internet bridge to your small Wi-Fi network and play network-hosted or Internet-hosted audio content through the radio’s speaker. It would be important where the radio’s amplifier and speaker does a better job at reproducing music compared to what the Amazon Echo or Google Home device.

… as could devices like the Lenovo Smart Display

For example, you could ask Alexa or Google Assistant to select a station and the local broadcast signal will then play. Or if you use something like Google Home Hub, you could have the station’s audio coming through the radio while a graphically-rich interface for that station appears on the Home Hub’s screen.

What RadioDNS needs to look towards is the idea of using Bluetooth or similar peripheral-level connections as a way of allowing a companion computing device to facilitate hybrid radio functionality for equipment or use environments that don’t support integrated Internet connectivity.

Emergency-alert buttons like this Ekahau Wi-Fi name-tag panic-button setup will be influencing network architecture for the Internet Of Things

The Hotel Panic Button Could Redefine Hospitality Networking | IoT World Today

My Comments

In some workplaces where staff work alone at night or other times where they are in danger, portable emergency-call buttons are often used. Initially they were the same size as an older garage-door opener but they are becoming the size of a pendant, badge or fob. As well, rather than these devices lighting up a separate alert panel, they light up a message or “throw up” a map with an indicator on a regular computer running building-security software to show where the danger is.

Initially, they were being positioned for very-high-risk workplaces like psychiatric care or the justice and allied settings. But other workplaces where staff work alone are seeing these devices as an important safety measure, usually due to various occupational health-and-safety requirements.

For example, hotels in the USA are moving towards having Housekeeping staff use these devices in response to workplace agreements, industry safe-work safe-premises initiatives or city-based legal requirements. But these systems are being required to work in conjunction with the Wi-Fi networks used by staff and guests for business and personal data transfer.

A device of the kind that I had covered previously on HomeNetworking01.info was the Ekahau Real Time Location System. This was a pendant-style “panic-button” device, known as the T301BD Pager Tag which had an integrated display and call button. It also had a setup that if the tag was pulled at the nexkstrap, it would initiate an emergency response.  I also wrote an article about these Ekahau devices being deployed in a psychiatric hospital as a staff emergency-alert setup in order to describe Wi-Fi serving a security/safety use case with the home network.

This application is being seen as a driver for other “Internet-of-Things” and smart-building technologies in this usage case, such as online access-control systems, energy management or custom experiences for guests. As I have said before when talking about what the smart lock will offer, the hotel may be seen as a place where most of us may deal with or experience one or more of the smart-building technologies. Also I see these places existing as a proving ground for these technologies in front of many householders or small-business owners who will be managing their own IT setups.

One of the issues being drummed up in this article is quality-of-service for the Internet Of Things whereupon the device must be able to send a signal from anywhere on the premises with receiving endpoints receiving this signal with no delay. It will become an issue as the packet-driven technologies like the Internet replace traditional circuit-based technologies like telephone or 2-way radio for signalling or machine-to-machine communication.

The hotel application is based around the use of multiple access points, typically to provide consistent Wi-Fi service for staff and guests. Such a setup is about making sure that staff and guests aren’t out of range of the property’s Wi-Fi network and the same quality of service for all network and Internet use cases is consistent throughout the building. Here, concepts like mesh-driven Wi-Fi, adaptive-antenna approaches, load-balancing and smart smooth roaming are effectively rolled in to the design of these networks.

Wi-Fi access points in the smart-building network will also be expected to serve as bridges between IP-based networks and non-IP “Internet-of-Things” networks like Bluetooth Low Energy (Bluetooth Smart), Zigbee, Z-Wave or DECT-ULE. These latter networks are pushed towards this application class due to the fact that they are designed to support very long battery runtimes on commodity batteries like AA Duracells or coin-style watch batteries. There will be an emphasis on localised bridging and the IP-network-as-backbone to provide better localisation and efficient operation.

These systems are being driven towards single-screen property-specific dashboards where you can see the information regarding the premises “at a glance”. I would reckon that operating-system-native applications and, perhaps, Progressive Web App versions will also be required to use operating-system-specific features like notification-panels to improve their utility factor in this context.

As far as the home network is concerned, I do see most of these technological concepts being rolled out to the smart home with an expectation to provide a similar service for householders and small businesses. This is more important as ISPs in competitive markets see the “Internet of Things” and improved Wi-Fi as a product differentiator.

The use of multiple Wi-Fi access points to cover an average home being made real for a home network thanks to HomePlug wireless access points, Wi-Fi range extenders and distributed-Wi-Fi systems that will bring this kind of localised Wi-Fi to the smart home. Typically this is to rectify Wi-Fi coverage shortcomings that crop up in particular architecture scenarios like multi-storey / split-level premises and use of building materials and furniture that limit RF throughput. It is also brought about thanks to the use of higher-frequency wavebands like 5GHz as Wi-Fi network wavebands.

There will be an industry expectation to require access points and similar devices to provide this kind of “open-bridging” for Internet-of-Things networks. This is more so where battery-operated sensor or controller devices like thermostatic radiator valves and smart locks will rely on “low-power” approaches including the use of Zigbee, Z-Wave or similar network technology.

It will also be driven typically by carrier-supplied routers that have home-automation controller functionality which would work with the carrier’s or ISP’s home-automation and security services.

To the same extent, it may require “smart-home / building-automation” networks to support the use of IP-based transports like Wi-Fi, HomePlug and Ethernet as an alternative backhaul in addition to their meshing or similar approaches these technologies offer to extend their coverage.

In some cases, it may be about Zigbee / Z-Wave setups with very few devices located at each end of the house or with devices that can’t always be “in the mesh” for these systems due to them entering a “sleep mode” due to inactivity, or there could be the usual RF difficulties that can plague Wi-Fi networks affecting these technologies.

DECT-ULE, based on the DECT cordless-phone technology and is being championed by some European technology names, doesn’t support meshing at all and IP-based bridging and backhauls could work as a way to extend its coverage.

Such situation may be rectified by access points that use a wired backbone like Ethernet or HomePlug powerline.

In the context of the staff panic button use-case, it will roll out to the home network as part of a variety of applications. The common application that will come about will be to allow the elderly, disabled people, convalescents and the like who need continual medical care to live at home independently or with support from people assuming a carer role.

This will be driven by the “ageing at home” principle and similar agendas that are being driven by the fact that people born during the post-war baby boom are becoming older as well as the rise of increased personal lifespans.

Similarly, this application may also be underscored as a security measure for those of us who are concerned about our loved ones being home alone in a high-risk environment. This is more so in neighbourhoods where the risk of a violent crime being committed is very strong.

But I would see this concept work beyond these use cases. For example, a UK / European central-heating system that is set up with each radiator equipped with a “smart” thermostatic radiator valve that is tied in with the smart-home system. Or the use of many different control surfaces to manage lighting, comfort and home-entertainment through the connected home. This is something that will rise up as most of us take on the concept of the smart home as the technology standardises and becomes more affordable.

What is being highlighted is the requirement for high quality-of-service when it comes to sending “Internet-of-Things” signalling or control data as our networks become more congested with more gadgets. Similarly, it is about being able to use IP-based network technology as a backhaul for non-IP network data that is part of the Internet-of-Things but providing the right kind of routing to assure proper coverage and quality-of-service.
