OneWeb presents their Vision for LEO Satellites and 6G Connectivity

In previous posts we looked at how OneWeb is trying to implement 5G in their satellite networks from the start. In a recent talk at 5G Forum Korea, Massimiliano Ladovaz, CTO of OneWeb presented their Vision for LEO Satellites and 6G connectivity

Any issues OneWeb was facing, are past problems, and in the last year they have not only sorted that out but also managed to make good progress with their launches. 

Back in December, OneWeb successfully launched 36 satellites, bringing total in-orbit constellation to 394 satellites. They have now launched over 60 percent of their LEO satellite fleet that has been promised to deliver high-speed, low-latency global connectivity. They ended 2021 with nine launches completed since December 2020, and several partnerships and agreements signed.

During the talk, Massimiliano highlighted many features and progress of OW (OneWeb) satellite constellation, including that even though the architecture was based on LTE standards, they expect eventual migration to 5G and 6G. 

OW's Gen2 is expected to be 6G ready by 2026. While they are expecting the standards to fully define interoperability with 5G (and 4G), all development will focus on newer standards going forward. 

The video of the talk is embedded below:

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

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.

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
