Fibre-to-the-room (FTTR / FTTRoom)

Fibre-to-the-room (FTTR) is a new kind of in-premises networking technology which is based on optical fibre communication. With the benefit of optical fibre, FTTR will provide high-bandwidth and reliable transmission. It is envisaged that the topology and functionalities of FTTR technologies may be different from the current fibre-based technologies in transport and access network, and consequently it is necessary to understand the use cases of FTTR and derive the corresponding network requirements for subsequently developing specifications.

Earlier this year, I blogged about the ETSI ISG F5G that aims to study the fixed-network evolution required to match and further enhance the benefits that 5G has brought to mobile networks and communications. The intention of F5G is that it will define improvements with respect to previous solutions and the new characteristics of the fifth-generation fixed network. This will open up new opportunities by comprehensively applying fiber technology to various scenarios, turning the Fiber to the Home paradigm into Fiber to Everything Everywhere.

ITU-T recently published Technical Paper on "Use cases and requirements of fibre-to-the-room". It collects the use cases (including in-home Wi-Fi backhauling, broadband deployment for dense apartment building, network infrastructure for smart office, Internet of things (IoT) support of smart home, low latency service in home networks, fibre deployment for FTTR for residential scenarios, network slicing, eastwest data transmission in home network), where FTTR can be used. Each use case is introduced by a scenario of fibre-based network in home domain and analyses the new demand on network capability.

There was also a Joint ETSI ISG F5G, BBF, CCSA TC6 and ITU-T SG15 Workshop on "FTTR" (Fibre to the room) back in June. The presentations and recording of the event are all 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
