Press Release (German – Deutsch)

My Comments

Devolo have become the first manufacture to exploit G.Hn HomeGrid “no-new-wires” technology in a retail setting. Here, they have exploited this in their Magic range of powerline-network devices that use this technology rather than HomePlug AV2 technology which their dLAN range of powerline network devices support.

Why is this so? There is continued development of G.Hn HomeGrid technology with on-premises powerline technology moving towards 2.4GHz bandwidth as well as improved operation for “simple yet secure” network setup. This includes improved performance for powerline-network setups within apartments and similar single-building many-premises developments. Another factor is that G.Hn HomeGrid technology isn’t dependent on a particular wired physical connection medium – it can work with traditional phone-line cabling or TV coaxial cabling.

This was thanks to the HomePNA phone-line-based home-network technology being absorbed by the HomeGrid Alliance and brought in to the ITU G.Hn standards.

But Devolo are taking this further by offering a G.Hn HomeGrid kit that uses either TV coaxial cabling or phone-line cabling to establish a Gigabit point-to-point link using no new wires. But who are they pitching this kit to?

In Germany at least, a significant number of fibre-to-the-premises installations for single-family homes or terrace-style (townhouse-style) homes have the optical-network terminal installed in the house’s basement. The householders then end up installing the home-network Wi-Fi broadband router downstairs in that basement. But they lose out on Wi-Fi performance thanks to the ground floor being made of dense materials that absorb radio waves associated with the Wi-Fi network segment.

A very similar installation scenario affecting some single-family houses with an attached garage is to have the optical network terminal for a fibre-to-the-premises setup installed in that garage. Some of these dwellings may have the wall between the garage and the house proper heavily insulated or thickened because the garage isn’t seen as living space and that wall may be built out of or insulated with material that attenuates radio waves.

The household then has to consider using a Wi-Fi range extender, a powerline-based Wi-Fi access point kit or a mesh network setup to improve the Wi-Fi reception in their living spaces upstairs. This may be good enough if the basement is being purposed as some form of living space like a games room or young adult child’s bedroom.

But this device is designed to connect to the Ethernet WAN connection between the ONT and the Wi-Fi broadband router and “extend” that so the router is installed in the living areas. As well, it is meant to use the telephone cabling or the coaxial cabling associated with a TV aerial, cable TV service or satellite dish.

Here, it is built on the assumption that a lot of the telephone wiring or the TV-aerial wiring is consolidated and exposed within the basement or garage, typically for the convenience of the installers. This will usually be the sign of a properly-installed TV or telephony setup where these spaces were taken advantage of rather than a series of splitters or junction boxes installed downstream to cater for ad-hoc installation of extra phone or TV points.

They offer a similar device that uses G.Hn HomeGrid powerline connectivity for this same purpose. This device, known as the Fiber Connect, isn’t compatible with the HomePlug powerline connectivity standards and is focused as a point-to-point device

At the moment, the Devolo Giga Bridge device is focused on a point-to-point setup primarily for extending the Ethernet (WAN) connection further out. As Devolo works on implementing the G.Hn HomeGrid standard further for home networks, it could be about developing it to work with their Magic G.Hn powerline implementation or implementing it as a multipoint setup for phone-line or TV coaxial setups.

What is showing up here is that Devolo are putting their faith in the G.Hn HomeGrid home-network approach especially in the retail and direct-to-consumer marketspace. This is compared to only marketing devices based on that technology to ISPs, telco and professional installers who supply and install these devices.

The Spotify disinformation podcast saga could give other music streaming services a chance

Spotify dabbling in podcasts and strengthening its ties with podcasters is placing it at risk of carrying anti-vaxx and similar disinformation

Nils Lofgren Pulls Music From Spotify – Billboard

My Comments

Spotify has over the last two years jumping on the podcast-hosting wagon even though they were originally providing music on demand.

But just lately they were hosting the podcast output of Joe Rogan who is known for disinformation about COVID vaccines. They even strengthened their business relationship with Joe Rogan using the various content monetisation options they offer and giving it platform-exclusive treatment.

There has been social disdain about Spotify’s business relationship with Joe Rogan due to social responsibility issues relating to disinformation about essential issues such as vaccination. Neil Young and Joni Mitchell had pulled their music from this online music service and an increasing number of their fans are discontinuing business with Spotify. Now Nils Lofgren, the guitarist from the E Street Band associated with Bruce Springsteen is intending to pull music he has “clout” over from Spotify and encourages more musicians to do so.

Tim Burrowes, who founded Mumbrella, even said in his Unmade blog about the possibility of Spotify being subject to what happened with Sky News and Radio 2GB during the Alan Jones days. That was where one or more collective actions took place to drive advertisers to remove their business from these stations. This could be more so where companies have to be aware of brand safety and social responsibility when they advertise their wares.

In some cases, Apple, Google and Amazon could gain traction with their music-on-demand services. But on the other hand, Deezer, Qobuz and Tidal could gain an increased subscriber base especially where there is a desire to focus towards European business or to deal with music-focused media-on-demand services rather than someone who is running video or podcast services in addition.

There are questions about whether a music-streaming service like Spotify should be dabbling in podcasts and spoken-word content. That includes any form of “personalised-radio” services where music, advertising and spoken-word content presented in a manner akin to a local radio station’s output.

Then the other question that will come about is the expectation for online-audio-playback devices like network speakers, hi-fi network streamers and Internet radios. This would extend to other online-media devices like smart TVs or set-top boxes. Here, it is about allowing different audio-streaming services to be associated with these devices and assuring a simplified consistent user experience out of these services for the duration of the device’s lifespan.

That includes operation-by-reference setups like Spotify Connect where you can manage the music from the online music service via your mobile device, regular computer or similar device. But the music plays through your preferred set of speakers or audio device and isn’t interrupted if you make or take a call, receive a message or play games on your mobile device.

What has come about is the content hosted on an online-media platform or the content creators that the platform gives special treatment to may end up affecting that platform’s reputation. This is especially where the content creator is involved in fake news or disinformation.

What is Wi-Fi 7 to provide for your Wi-Fi wireless network?

Wi-Fi 7 is coming, and Intel makes it sound great | Network World

My Comments

Wi-Fi 6 is already established as a wireless network standard and this is being taken to  Wave 2 with some incremental improvements.

But Wi-Fi 7, is to be coming soon and is actually the IEEE 802.11be wireless-network standard which is expected to be the follow-on to Wi-Fi 6.

It is expected to offer 320MHz bandwidth for each RF channel and provide a theoretical link-layer throughput of 96.1Gbps. As well, a Wi-Fi 7 wireless network segment is expected to be able to work on the 2.4 GHz, 5GHz and 6GHz radio bands.

This will support multi-link operation where network devices can work on multiple channels across multiple wavebands at once. This allows for a “fat pipe” that carries more data along with reduced latency (important for games or videocalls) and increased operational robustness. This latter benefit is provided by allowing particular data to use particular channels.

Wi-Fi 7 is to lead wireless network segments towards multiple-gigabit networking. As well, Wi-Fi 7 will have integrated support for Wireless Time-Sensitive Networking which assures synchronous delivery of data to multiple endpoints with use cases being multichannel sound, multi-camera setups or robotics and industrial automation.

This technology will take time to come to fruition even if it is “cemented in stone” by the IEEE now. There will be the need to see the necessary silicon being made available to client-device and network-infrastructure manufacturers so they cam implement it in their own products. This will also include the requirement to to see power-efficient Wi-Fi 7 client-device silicon implementations before a significant number of portable devices come with this technology.

Then the client and network infrastructure devices will appear but be at that price point and marketing position that only appeals to early-adopters who will pay a premium to have the latest and the greatest. But a few years later will see Wi-Fi 7 be a mature wireless-network technology.

But this will come in to its own with ubiquitous ultra-high-definition TV, augmented and virtual reality along with computing environments pitched towards gamers, creators and mobile-workstation users.

My Comments

As part of the ongoing effort to tackle the COVID-19 coronavirus plague, many a jurisdiction is setting up COVID-19 testing facilities around their cities and towns. These are to identify who has and hasn’t caught this virus so proper measures can be taken.

In most situations the tests being done are PCR-based tests that require a mucus sample to be taken from the patient’s nose and throat for analysis, with the results coming through by at the most 24 hours. An increasing number of these facilities are of the “drive-through” kind where the patients drive up to the facilities and the nurses take the swabs from the patients while they sit in their cars.

But staff at one such “pop-up” facility in Melbourne noticed that most of the patients coming through that site had a dog with them in their car. Typically patients did this due to the pet being a security blanket or simply to take the dog out in the car with them. As well the staff, who were working long days in full PPE clothing, found that the presence of these furry companions in the patients’ cars as something to lift their spirits.

One of the staff noticed this and asked patients if they can take photos of their canine companions then, when the patient agreed, they took the photos. These ended up on a special Instagram account which was effectively a “photo reel” of these dog and other animal pictures.

This has started to come popular with more staff at other drive-through COVID testing clinics contributing these images to the account’s photo roll especially as pop-up testing clinics relocated around the city. Even other drive-through testing sites around Australia and the rest of the world were contributing the pictures of their patients’ furry companions to this reel. Of course, being started in Australia, the “SwabDogsOfInsta” account features a few kelpies and Australian Cattle Dogs (Blue Heelers) as part of the montage.

The “SwabDogsOfInsta” ended up as a popular Instagram account to follow around the world with significant media coverage about it. People would leave various lovely comments about these dogs with some referencing the animal in the photo being similar to one they had at some point in their life journey. As well, these pictures come in to their own to cheer everyone up during these difficult times.

Even with the newer COVID Omicron variant doing the rounds and these drive-through testing clinics being “bogged” with many people seeking PCR-based swab tests, this reel is being built out with more of the dogs that are accompanying the many patients at the facilities.

If Instagram had the ability to work with screen-saver / automatic-wallpaper-changer software or electronic picture frames and has the ability to show particular accounts’ images on that kind of software or hardware, this could be the kind of account that would work well with such a setup.

But simply, it’s a good account to add to your Instagram “follow” collection if you are wanting something that takes your mind off difficult times.

Boeing to launch LEO satellite network

FCC Authorizes Boeing V-Band LEO Broadband Constellation – Via Satellite – (satellitetoday.com)

My Comments

The Puget Sound area of Washington State in the USA now has two actors in the low-earth-orbit satellite broadband game.

This was initially Jeff Bezon’s Project Kuiper effort that is starting to pick up steam, but Boeing, associated with the likes of some well-known airliners which you most likely have flown on many times, is now getting the go-ahead to build a constellation of these satellites.

The initial FCC permit will allow Boeing to launch 147 LEO satellites which will be for civil-use cases like residential, commercial and institutional use initially within the USA then globally. The wavebands they will be licensed to work in are part of the V-band radio spectrum for both space-to-ground and inter-satellite communications. They have six years to develop the constellation and launch half of the satellites as part of the licence.

Here, it will be about Boeing joining a relatively-crowded market for LEO satellite broadband which will be a boon for use cases like real broadband in rural and remote areas; alongside broadband Internet within transport services.

But how will Boeing join this market? Could this be through offering a retail service like SpaceX’s Starlink or to offer it as a wholesale service in a similar manner to OneWeb. That is where retail ISPs could resell Boeing’s service to local customers.

There will be the issues of having a retail service licensed for operation in multiple countries especially where some countries are particular about preferring companies chartered in their jurisdiction offer telecommunications and allied services. A wholesale approach can allow a country’s own telcos and ISPs to resell satellite broadband to all user classes.

There is also the question about Boeing being tempted to vertically integrate this service with their lineup of civil aircraft. This could mean that they could get more airlines who fly the likes of the 737 or the 787 Dreamliner to offer a high-bandwidth Internet service provided by their LEO satellite constellation as a passenger amenity.

If Boeing can get these low-earth-orbit broadband satellites off the ground and yielding a viable service, this could be a viably competitive market when it comes to satellite broadband.

Wi-Fi CERTIFIED HaLow™ delivers long range, low power Wi-Fi® | Wi-Fi Alliance

Wi-Fi CERTIFIED HaLow (Product Page)

My Comments

A Wi-Fi network technology that is being put on the map at the moment is Wi-Fi CERTIFIED HaLow a.k.a Wi-Fi Halow.

This network technology is based on IEEE 802.11ah wireless network technology and works on the 900MHz waveband. It is about long-range operation of approximately 1 kilometre from the access point and very low power operation that allows devices to run for a year on commodity batteries like a single 3V coin-size cell or a pair of AA-size Duracells.

The power requirement may be a non-issue for devices like HVAC thermostats that are wired to the heating system they control. But they may be an issue with devices like movement sensors or smart locks that are dependent on their own battery power. As well, the low power requirements that Wi-Fi HaLow offer could be of benefit towards devices that implement energy-harvesting technology like solar power or kinetic energy.

Wi-Fi HaLow feature list courtesy of Wi-Fi Alliance

This low-bandwidth Wi-Fi specification is intended to complement the other Wi-Fi specifications used with your home or business network. But it is focused towards the Internet of Everything especially where the devices are to be operated across a wide radius like a farm or campus.

The network topography for a Wi-Fi HaLow network segment will be very similar to the standard Wi-Fi network. That is where multiple client devices link to an access point, but there should be the ability for a mobile device to roam between access points associated with the same Wi-Fi network.

Compared to the likes of 802.15 Zigbee, Z-Wave, DECT-ULE, Bluetooth LE and similar Internet-of-Things wireless technologies, this is meant to avoid the need for special routers when there is a desire to link them to IP-based networks.

This is because this technology effectively uses the same protocol stack as our Wi-Fi networks save for the layers associated with the radio medium. It also means that the same security, connectivity and quality-of-service protocols that are part of Wi-Fi nowadays like EasyConnect and WPA3 can be implemented in Wi-Fi HaLow devices.

At the moment, you would need to use a Wi-Fi HaLow access point to get any Internet-of-Things devices on to your network and the Internet. It may be a small device that plugs in to your existing home network router or network infrastructure. But a subsequent Wi-Fi access point or router design could have built-in support for this standard thus making it more ubiquitous.

The use cases being positioned for Wi-Fi HaLow technology would encompass the smart home, the smart building and the smart city where all sorts of “Internet-of-Things” devices are acting as controllers or sensors. It is also encompassing vertical use cases like agriculture, industry and medicine where sensors come in to play here.

At the moment, this kind of connectivity will exist as an alternative to Zigbee, Z-Wave and similar technologies especially where IP-level connectivity and functionality is wanted at the device. It may not have ready appeal in use cases where a direct connection to Internet-based technology may not be required.

On the other hand, a use case could allow for a “hub and spoke” approach to the Internet of Things where a device can connect to accessory peripheral devices using Zigbee or Bluetooth but link to the home network and Internet via WI-Fi HaLow. An example of this could be a retrofit-install smart lock which supports the use of accessory input devices like keypads, NFC card/fob readers and contact sensors.

Wi-Fi HaLow could be seen as a direction towards capable low-power long-distance wireless networking for Internet of Things, especially where direct Internet / LAN network connectivity is desired out of the application.

My Comments

Qobuz is a music service that was founded in France in 2007. This service offers sobscription-based music streaming and transactional download-to-own music purchasing but offers these services with Hi-Fi-grade sound. It had existed in Europe for a long time and since 2020, Australians and New Zealanders can use this service to stream or purchase high-quality music.

Here, the music is available using lossless streaming and file formats with CD-quality audio as a baseline and the option for master-grade audio. There is also the ability to download a PDF copy of the album’s liner notes which typically will have lyrics for an album’s songs or a biography and discography in the case of a artist-specific compilation.

The Studio Premium subscription costs AUD$24.99 per month or AUD$229.99 per year which offers up to “master-grade” streaming quality. There is also a more expensive Studio Sublime+ subscription tier costing AUD$299.99 per year which gives you a discounts for “download-to-own” music tracks that you purchase.

There are native clients for Windows, Mac OS, Android and iOS along with the ability to interact with Qobuz through the Web. The Android and iOS apps allow streaming of Qobuz audio through the Apple AirPlay or Google Cast (Chromecast) to endpoint devices compatible with these protocols. Issues that were raised include the desktop apps for Windows and Mac OS regular computers not being available through the operating systems’ native app stores. This may be of issue where the app stores are preferred by some users as a software update path.

Qobuz can work with Naim equipment

As far as other devices are concerned, there is support for Sonos speakers and some network-capable hi-fi equipment, usually some of the premium hi-fi brands like Sony, Yamaha, Linn or Naim. But none of the popular games consoles, smart speakers or smart TVs don’t support Qobuz yet in a native manner.

But the omission of synchronous lyrics or music videos on Qobuz is more about focusing this service to music listening.  This is similar to how most of us would be listening to our music whether on packaged media like vinyl or CD; or as file-based audio and we either want it in the background or to concentrate on the actual music.

There will still be calls for interlinking Qobuz, Deezer and Tidal with music-recognition services or the Shazam or Soundhound kind so people who hear songs on the radio for example can bring them up on these high-quality services. Similarly, there will be the need to make curated playlists available across multiple platforms through the use of a standard datatype and export / import abilities.

At least Qobuz is coming to the fore as a high-quality file-based audio service that offers both a subscription-based streaming approach and a transactional download-to-own approach for your music.

How could CD-quality lossless audio be marketed when it comes to streaming

Sony MAP-S1 network CD receiver

A strong direction for music streaming services is to offer CD-quality sound for all of their library at least

Apple, Amazon and Spotify are lining up or have lined up hi-fi-grade service tiers as part of their audio-streaming services. It is in response to Tidal and Deezer already offering this kind of sound quality for a long time along with the fear of other boutique audio-streaming services setting up shop and focusing on high-quality audio.

Now there is something interesting happening here regarding hi-fi-grade streaming. Here, Apple is having a CD-grade lossless-audio service as part of their standard premium subscription while making sure all music available to their Apple Music streaming service is CD-quality.

So how could these streaming music services compete effectively yet serve those of us who value high quality sound from those online music jukebox services that we use?

What are these hi-fi-grade digital audio services about?

Spotify Windows 10 Store port

This will be something that is expected of Spotify at least

The hi-fi-grade service tiers typically offer a sound quality similar to that of a standard audio CD that you are playing on your CD player, with the same digital-audio specifications i.e. 44.1 kHz sampling rate and 16-bit samples representing stereo sound. Some of these services may offer some content at 48 kHz sampling rate that was specified for the original DAT audio tapes and may be used as a workflow standard for digital radio and TV.

In the same way that a regular audio CD stores the audio content in the original uncompressed PCM form, these hi-fi-grade streaming services use a lossless data-compression form similar to the FLAC audio filetype to transmit the sound while preserving the sound quality. That is equivalent to how a ZIP “file-of-files” works in compressing and binding together data from multiple files.

CD-grade digital audio was adopted during the late 1980s as the benchmark for high-quality sound reproduction in the consumer space. As well, the DAT tapes that recorded 16-bit PCM audio at 44.1 or 48 kHz sampling rates were considered the two-channel recording standard for project studios and similar professional audio content-creation workflows. It is although MiniDisc which used a lossy audio codec caught on in the UK and Japan for personal audio applications.

Some of these services offer extras like surround-sound or object-based audio soundmixes or supply the audio at “master-grade” specifications like 96 or 192 kHz sampling rates or 24 or more bits per sample. But these are best enjoyed on equipment that would properly reproduce the sound held therein to expectations. This is while most good audio equipment engineered since the 1970s was engineered to work capably with the audio CD as its pinnacle.

The provision of these hi-fi-grade services is having appeal thanks to telcos and ISPs offering increased bandwidth and data allowances for fixed and mobile broadband Internet services. This is more so in markets where there is increased competition for the customer’s fixed or mobile Internet service dollar.

As well, there is a highly-competitive market war going on between Bose, Apple and Sony at least for high-quality active-noise-cancelling Bluetooth headsets with the possibility of other headset manufacturers joining in this market war. This is something very close to the late-1970s Receiver Wars where hi-fi companies were vying with each other for the best hi-fi stereo receivers for one’s hi-fi system and increasing value for money in that product class.

Here, a streaming music service that befits these high-quality in-ear or over-the-head headsets could show what they are capable of when it comes to sound reproduction while on the road.

Let’s not forget that Apple and others are working on power-efficient hi-fi-grade digital-analogue-converter circuitry for laptops, tablets, smartphones and other portable audio endpoint devices. Then hi-fi-grade digital-analogue-conversion circuitry that connects to USB or Apple devices is being offered by nearly every hi-fi name under the sun whether as a separate box or as part of the functionality set that a hi-fi component or stereo system would offer.

Current limitations with enjoying hi-fi-grade audio on the move

There are limitations with this kind of service offering, especially with the use of Bluetooth Classic streaming to headphones or automotive infotainment setups from mobile devices. At the moment, it is being preferred that a wired connection, whether via a traditional analogue headphone cable or via an external digital-analogue converter box, is used to run the sound to a pair of good-quality headphones while “on the road”.

Similarly, Apple’s and Google’s smartphone-automotive-integration platforms need to be able to support use of these hi-fi-grade audio services properly so you can benefit from this class of sound when you are at the wheel of your car.

What could be done?

One step that can be taken by many music-streaming services is to create a service-level distinction between CD-quality stereo lossless audio service and create a higher-grade extra-cost audio services that focus on “master-grade” or multichannel soundmixes.  Here, most of us like our music in stereo sound and see CD quality sound as the pinnacle with equipment engineered to that calibre. This is while the esoteric audiophiles would invest in equipment and services that can handle master-grade audio or multichannel soundmixes.

The music services could them move towards offering the CD-quality stereo lossless sound as the audio quality for the standard paid service subscription. That includes moving the service’s music library towards that kind of quality. The user would need to have the ability to enable and disable the CD-quality lossless stereo sound on a device-by-device basis perhaps to cater for smartphone use or limited bandwidth.

Where a music service offers transactional “download-to-own” music, the recordings could be offered at CD quality stereo as lossless files. There could be the ability to provide a complementary download of previously-purchased material as the CD-quality stereo lossless files.

At the moment, there are a number of open-frame and proprietary paths that are able to use a home network to transmit CD-quality or master-quality lossless digital audio from a computing device or streaming audio service to audio endpoint devices within the home. But there needs to be more done to support mobile and portable setups where one is likely to hear audio files while out and about.

The Bluetooth SIG could investigate how CD-quality lossless audio can be sent wirelessly between devices using the various audio profiles that they oversee. This is more so as Bluetooth is used primarily to send multimedia audio from a smartphone or tablet to speakers, headphones or home and car audio equipment. Here, it could be based on their Bluetooth LE Audio specification which is being used to revise the Bluetooth multimedia audio use case effectively.

Similarly, the use of USB-C as a “digital audio path” from a computing device to an audio-output device needs to be encouraged. This would come in to its own with connecting to audio devices or systems that have highly-strung digital-analogue conversion circuitry which can come in to its own with high-quality audio streaming services.

In the automotive context, Apple CarPlay and Android Auto which are used to provide integrated smartphone-dashboard functionality could be improved to provide lossless audio transfer between the smartphone and the car’s infotainment system. This may be valued as a differentiator that can be applied to premium car-audio setups.

Once there are a list of standard protocols adopted for streaming lossless hi-fi grade stereo sound to headsets and automotive setups and that support wired and wireless connectivity, this could make proper CD-quality stereo sound more relevant on the road.

IKEA introduces new SYMFONISK picture frame WiFi speaker (Press Release)

My Comments

IKEA have added another speaker to their Sonos-based SYMFONISK multi-room speaker lineup, continuing their idea of an affordable path to the Sonos network multi-room audio platform. These work in the same way as Sonos speakers and you can establish a Sonos-based multi-room audio setup based on a mix of Sonos or IKEA SYMFONISK speakers and use your home network’s Wi-Fi segment to transmit the sound.

The previous SYMFONISK speakers came in the form of a traditional bookshelf speaker and a table lamp. But this latest product has been described as appearing in the form of a picture frame but you have to use IKEA’s decorative art panels for these speakers. Here, it is more about the front of these speakers serving as the speaker grille that allows the sound to come out.

These speakers are able to be mounted on a wall or can stand on a table. But the framework and legs that allows them to stand on a table is designed to allow them to reproduce sound without adding extra vibration or noise to that sound as what is expected for a speaker enclosure.

There are hardware buttons on the IKEA SYMFONISK wall-art speakers to adjust the volume and start or stop the music with. But you use the Sonos mobile-platform apps or desktop software to choose what you want to hear through these speaker.

It is expected for IKEA to sell the SYMFONISK wall-art speakers for US$199 each with replacement wall-art fronts for US$20 each. But it will be interesting to hear whether these speakers can displace the SONOS One when it comes to sound quality

From what I have seen, it seems like IKEA have bothered to stay on with the Sonos-driven SYMFONISK network multiroom audio platform if they have bothered to design and market another SYMFONISK speaker. But it could mean that people who use the Sonos multiroom audio platform could be buying these IKEA speakers to build out their setup in a cost-effective manner.
