5G and Electromagnetic energy (EME)

Every time a new generation of mobile technology is being rolled out, there are scare stories about the radiation, cancer, etc. I last wrote a post on this topic back in 2011 and also in 2009. The main thing that has changed since is that 5G is being rolled out today as 4G was being rolled out then.

The Australian operator Telstra recently completed extensive testing of their 5G network infrastructure in real-world settings using commercially available 5G devices, and their data confirms two things. Firstly, the 5G technology produces electromagnetic energy (EME) levels at around 1000 times below the safety limits in many cases. Secondly, all the testing has found 5G EME levels to be similar to 3G, 4G and Wi-Fi. You can read the details and complete report here.

Last month I went to a seminar titled 'Update on Current Knowledge of RF Safety', organised by CW Radio Technology Group and National Register of RF Workers. Richard Hargrave from BT explained the challenge with compliance when a 5G carrier is added.

The implications as he said are:

• Some sites in urban areas become increasingly difficult to provide required capacity while maintaining compliance using standard designs
• Significant time and cost can be associated with works necessary to ensure compliance – new planning permissions, physical structures, new site acquisition etc
• As 5G is deployed further, particularly as additional spectrum is auctioned in 700MHz and 3.6-3.8GHz bands these problems will be exacerbated

His presentation is available here. Another presentation from Moray Rumney, asking some tough question on 5G safety is available here. Simon Rockman has written a summary of this seminar on Forbes, here.

I heard the Swiss operator Sunrise mentioning in a presentation at 5G World 2019 that the EMF limit in Switzerland is 10 times stricter than the rest of the world. This implies that 5G in Switzerland is extremely safe. The slide from the presentation can be seen in the pic above.

We also have couple of related videos on this topic, maybe of interest:

3GPP 5G Standardization Update post RAN#84 (July 2019)

3GPP recently conducted a webinar with Balazs Bertenyi, Chairman of 3GPP RAN in which he goes through some of the key features for 5G Phase 2. The webinar also goes through the details of 5G Release-15 completion, status of Release-16 and a preview of some of Release-17 features.

Slides & video embedded below. Slides can be downloaded from 3GPP website here.

Looks like all presentations were not shared but the ones shared have lots of useful information.

Finland: A country with only Unlimited Data Plans

I was listening to Elisa couple of weeks back, at 5G World Summit. One of the things that surprised me was that Elisa offered unlimited data plans but the price varied based on the maximum speeds possible. The same approach was going to continue with 5G. When 5G data speeds would improve, new packages will be added with the improved speeds.

"There's no revenue upside with unlimited mobile data", say operators with bucket plans. Funny then that the all-unlimited Finnish MNOs @ElisaOyj @teliafinland @DNA_fi all had increasing ARPU in 2018 - in contrast to almost all mature market operators solely offering buckets.

— tefficient 🚥 (@tefficient) March 4, 2019

Tefficient has pointed out multiple times that even though all operators in Finland offer unlimited data plans, their ARPU has increased in 2018. This is in contrast to the other mature markets, even though they may not be offering unlimited data plans.

"Finnish operators that executed ‘unlimited everything’ strategies were the undisputed champions of the 4G era" #Rewheel https://t.co/APZXMXj7EH

— Pal Zarandy (@PZarandy) May 23, 2019

Same thing was pointed out by Rewheel research that highlighted in their May 2019 report that, "Finnish operators that executed ‘unlimited everything’ strategies were the undisputed champions of the 4G era"

A mashable article pointed out that "5G will be crazy fast, but it'll be worthless without unlimited data". This is very true.

When people talk about 8K video over 5G, most of them don't realise that it would consume roughly 7-10 GB data per hour on 8K video.

This article from @howtogeek - https://t.co/xSxvaMwKY4 shows some good calculations of up to 4K video pic.twitter.com/anJhNfUMtV

— Zahid Ghadialy (@zahidtg) June 15, 2019

Mobile operators should start thinking about how they can offer unlimited data plans, especially if they keep touting applications that are going to use loads of data. As you can see from the tweet above, a 1 hour 8K video streaming would roughly use between 7 - 10 GB of data.

Let me know your thoughts.

3GPP Release-16, Release-17 & Beyond...

6G Summit featured quite a few talks from people looking at evolution beyond Release-16. The future releases will still be 5G, maybe become 5.5G, like 3GPP Release-13 which was known as LTE-Advanced Pro officially was unofficially known as 4.5G.

Back at the 6G Summit in Finland, Dr. Peiying Zhu from Huawei looked at the topics being discussed for Release-17 and beyond.

Thanks to Mika Klemettinen for sharing the pictures on Twitter, as the presentation was not shared.

3GPP is working towards defining Release-16. TS 21.916 - Release description; Release 16 is still not yet available on the 3GPP reflector. Once that is available, we will know for sure about all the Rel-16 changes. Release-17 is long way away. Having said that, there is no shortage of discussions as some of these Rel-17 features were discussed in the recent RAN Plenary.

Jungwon Lee, VP, Samsung also shared a summary of 3GPP Release-16 and Rel-17 features at IEEE 5G Summit in San Diego recently. Quite a few interesting features in all the pictures above that we will no doubt look at in the future posts.

3GPP also shared a presentation recently (embedded below), looking at not only Release-15 & 16 but also looking at focus areas for Release-17

Couple of talks by NTT Docomo on 5G and Beyond (pre-6G)

The Japanese operator, NTT Docomo is a very bold MNO. Not only do they do interesting research but they are very open about what they have been doing and share it publicly. For example, last month they announced development of a safe, blade-free drone propelled by Ultrasonic Vibrations (tweet). This was just amazing as it has a potential to use drones in many new areas where the conventional drones are deemed too dangerous. This is why I was very pleased to see couple of talks by Docomo available online.

The first one is by Takehiro Nakamura, SVP and General Manager of the 5G Laboratories in NTT DOCOMO, Inc. at the 6G Summit in Finland. Slides available here. Video embedded below




The next one is by Seizo Onoe, Chief Technology Architect, NTT DOCOMO, INC. and President, DOCOMO Technology, Inc. from Brooklyn 5G Summit. Unfortunately the slides are not shared but the video is worth a watch below.
