Virve 2.0 is becoming a broad-band service

We have looked at the Finnish public safety network on The 3G4G Blog here. State Security Networks Group Finland (Erillisverkot) safeguards the Finnish society by offering authorities and critical operators engaged in critical infrastructure and services secure and reliable ICT services. 

At the core of the Virve 2.0 project is the secure and seamless transition from the current Virve to new services. Critical communication and mission control between authorities and other mission critical operators will be safeguarded under all circumstances. A recent update stated:

The highly tuned current Virve network for authorities will continue to work seamlessly alongside new services during the migration phase between 2023-2025. At the same time, the development of Virve 2.0 will proceed strongly in the areas of radio networks, information systems, devices, and application services.

Our desire is to conduct the development, testing and piloting of new services in close collaboration with Virve users. Preparing users for the upcoming change will also commence early on. What can they expect and when?

This is how Virve 2.0 is progressing: 

  • 2018–2019 Erillisverkot were appointed as the service provider for authorities’ mobile broad-band services. A comprehensive survey of the needs of Virve users along with interviews and workshops was started.
  • 2020 Ericsson was chosen as the provider for core information systems and Elisa was chosen as the radio network provider. Erillisverkot and Airbus Defence and Space, the provider of the current Virve network, renewed their maintenance contract, which will ensure the maintenance and usability of the current Virve during 2021–2025 with an option for an extension if needed.
  • 2021 Mission critical data subscriptions available. Procurement of devices moving forward.
  • 2022 Virve 2.0 services approved for operative use and ready for deployment.
  • 2023–2025 Migration period ongoing: current Virve services and Virve 2.0 functioning side by side.
  • 2024 The public competitive tendering for new applications (talk, data, and video services) will start once most customers have already transitioned to using Virve 2.0 services.
  • 2025– Virve 2.0 services will continue to be developed based on customer needs. The current Virve service contracts will ensure technical support for Tetra networks until 2030.

Erillisverkot published an international request for information regarding devices in the autumn of 2020. 22 organizations from around the world sent in responses. The English summary of the request for information is available here.

A Virve 2.0 mobile strategy brochure from last year is available here

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
