R&S Technical Explainer on 3GPP 5G Non Terrestrial Networks (NTN)

I have explained Non Terrestrial Networks (NTN) earlier here and have written a detailed article here. The initial 3GPP Release-15 version of 3GPP TS 22.261 added the initial requirement that the 5G system will be able to provide services using satellite access. A study was carried out by 3GPP as a part of 3GPP Release-16 and the results of the study on using satellite access in 5G networks have been documented in 3GPP TR 22.822. The document details the use cases, pre and post conditions, service flows, potential impacts / interactions with existing services / features and potential requirements based on the use case. The results from this technical report (TR) were then reflected in 3GPP Release-16 version of 3GPP TS 22.261. The document details the need for the 5G system to support service continuity between terrestrial 5G access and satellite based 5G access networks, owned by either the same operator or by an agreement between operators.

3GPP Release 17 will bring some interesting changes in the 5G NR standardization. The R&S explainer focuses on the future of non-terrestrial networks (NTN) and possible applications. In addition, it explores some NTN deployment scenarios and technology challenges.


I liked this NTN in one slide picture. Anyway, the talk is embedded below.

High-level Architecture Introduction of Mobile Cellular Networks from 2G to 5G

Here is an old tutorial explaining high level mobile network architecture, starting from GSM and then looking at GPRS, UMTS, LTE & 5G.

IEEE 802.11be Extremely High Throughput (EHT), a.k.a. Wi-Fi 7

We have been writing about Wi-Fi for a long time, weather it's to do with indoor connectivity , competition with 5G or just a name change to something simpler. When we last wrote about WiFi 6, a.k.a. 802.11ax, we were expecting a quick adoption of the technology in the industry. We are still not there yet.  You know what's strange? None of the new @madebygoogle gadgets from yesterday support Wi-Fi 6. Not the Pixel 5, not the Pixel 4a 5G, not the Nest Audio, and not the new Chromecast. pic.twitter.com/QtJ8iB9FeO — Ry Crist (@rycrist) October 1, 2020 Take for instance the new iPhone 12 supports Wi-Fi 6 in all their models as one would expect but none of the new Google Pixel phones (4a, 4a 5G and 5) support it. In fact none of the new Google devices support it. Which is rather bizarre. While we are still looking forward to Wi-Fi 6 becoming widespread, IEEE has already started working on the successor of 802.11ax, 802.11be - Standard for Information technology--Telecommunicati

CSI-RS vs SRS Beamforming

In an issue of Signals Flash by Signals Research Group (SRG), they talked about 2 different types of MIMO. Quoting from their journal, "CSI-RS versus SRS. Those operators that have tested or made token use of MU-MIMO leverage a flavor of MU-MIMO that is based on CSI-RS. The MU-MIMO network we tested was based on SRS, which makes it far more likely to observe sixteen spatial layers (versus eight)." I reached out to Emil Bj√∂rnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Link√∂ping University to see if he has explained this in any of his videos. Here is what he said: " I'm not talking about 3GPP terminology in any of my videos. But you can listen to the slides that starts around 12:40 in this video (embedded below) . If you are looking for CSI-RS vs SRS based MU-MIMO, then jump to around 12:40 in this video where you can see CSI-RS being referred to as "grid of beams" and SRS is similar to the other option, which is t
