'5G Ready' OneWeb Megaconstellation is Getting Ready for Commercial Launch

Last week, OneWeb announced that they have successfully launched another 36 Low Earth Orbit (LEO) satellites thereby bringing its total in-orbit constellation to 146 satellites. These will form part of OneWeb’s 648 LEO satellite fleet that will deliver high-speed, low-latency global connectivity.

In a written evidence submitted to the UK parliament back in May 2020, it said:

OneWeb is deploying the first satellite communication network with 5G features capable to deliver fibre-like connectivity to people around the world, especially in rural and hard to reach areas, powered by a constellation of Low Earth Orbit satellites.

5G ready, at low latency and providing global coverage, OneWeb will be the first telecommunication operator to bring high speed internet everywhere. Its communications network will offer game-changing Mobility solutions to industries that rely on global connectivity, such as Aviation, Maritime, Automotive and create solutions for Broadband, Government and Cellular Backhaul.

Deploying a 5G Ready Global Core network establishing an architecture which will enable a plug and play model for integration of the satellite system with terrestrial (5G) networks, OneWeb is uniquely positioned to provide a unique perspective on how telecommunications domestic capability can be built in the UK.


Satellite constellations are uniquely positioned to provide ubiquitous services and complement mobile network operators’ 5G services offloading their terrestrial networks with satellite connectivity.

With 5G, the satellite network will be developed to interoperate within a 5G architecture, offering functionalities for new use cases, such as connected cars, emergency services, dispersed manufacturing plants and remote sensors for IoT applications, while preserving high-value spectrum for low-latency- services.

Although 5G roll out is happening in urban areas, complete coverage will only be possible via the inclusion of non-terrestrial networks and, in particular, LEO satellite constellations.

The inclusion of the 5G ecosystem is key to the success of these new markets. The fundamental expertise and skills in 5G and small satellites resides in the UK and developing integrated systems represents an opportunity to leverage these into new business creation for such systems in 2020-30. The pathway to full 5G coverage and the realization of its real wealth creation is via satellite extension. Thanks to satellite constellations, like OneWeb, the UK has the exceptional opportunity of recovering an important part of the infrastructural and technological gap by harnessing the world leading expertise in 5G technology and the small satellites constellations to demonstrate extended roll out via low earth orbit (LEO) satellites, complementing the terrestrial 5G system and provide 100% coverage through seamless transition between the two and from a user point of view enjoying ubiquitous 5G services irrespective of geography.

5G will bring many new capabilities compared to previous generations of mobile networks. As well as providing higher throughputs, 5G will enable newer types of applications and services in the domains of health, transport, entertainment, machine-to-machine communications, and security, to name just a few. And Satellite communications will be an essential part of this 5G infrastructure. The satellite transport conduit will be integrated into the overall available communication map. Service providers will need to provide seamless connectivity between terrestrial and satellite. Traffic will be dynamically steered to the best transport options available according to bandwidth, latency, network conditions and other application-specific requirements. Several key changes introduced by 5G provide the scenario of using the service through satellite backhaul.


You can read the complete evidence here. Some of their claims of 5G ready from their website have been removed, though you can still watch the video here. In that video, Ruth Pritchard-Kelly, VP Regulatory Affairs, OneWeb is talking about the 5G Non-Terrestrial Networks. You can see our old tutorial here. We have also explained the different orbits of satellites, etc. in our other tutorial about connectivity on planes here.

Anyway, last year OneWeb had to enter chapter 11 bankruptcy filing and then successfully came out of it. We wrote about Starlink a few weeks back. If you are wondering how does Starlink & Oneweb compare, you can head to this excellent article here. The picture below shows the altitude comparison.

Here is a very recent video explaining how the OneWeb system works:

A slightly older version is quite interesting to watch too is here

We wrote a post on ITU Satellite webinars here. Embedded below is a talk from Ruth Pritchard-Kelly, ​Vice President,  Regulatory Affairs, OneWeb. As that is part of a bigger talk, if the video doesn't automatically jump to her talk, move to 1 hour 11 minutes 31 seconds.

As we mentioned, another 36 satellites were just launched. Details in press release here.

OneWeb network capabilities were also demonstrated to the US government. The video below provides the details including the speedtests, latency, etc.

Back in December, I wrote 21 predictions for 2021. Two of my predictions were related to LEO satellites. The first was that they will become commercial reality. The progress from Starlink can be shows this is true while my other prediction said that, "First Open RAN site with LEO satellite for backhaul is trialed with a commercial MNO". Still 9 months for that prophecy to be fulfilled 😉.

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation. The

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 Björnson, Visiting Professor at KTH Royal Institute of Technology and Associate Professor at Linköping 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

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. — 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
