The move to 10G PON from GPON and other PON


A passive optical network (PON) is a fiber-optic telecommunications technology for delivering broadband network access to end-customers. Its architecture implements a point-to-multipoint topology, in which a single optical fiber serves multiple endpoints by using unpowered (passive) fiber optic splitters to divide the fiber bandwidth between multiple access points. Passive optical networks are often referred to as the "last mile" between an Internet service provider (ISP) and its customers.

GPON stands for Gigabit Passive Optical Networks. GPON is a point-to-multi point access mechanism. Its main characteristic is the use of passive splitters in the fibre distribution network, enabling one single feeding fibre from the provider’s central office to serve multiple homes and small businesses.

I first wrote about the GPON standard 12 years back, in 2007. Since then it has evolved and has different flavours.


So while we are still using GPON heavily today, there is already a case being made by vendors like Huawei about why operators need to start investing in 10G PON. This video from Huawei is making case for GPON by showing 10 scenarios where it's needed.



IHS Markit Technology hosted a webinar with Huawei on this very topic.


This slide above makes a case for when 10G PON is needed. Based on the calculations (with caveats of course), if a SP is looking to offer anything above 200 Mbps consistently at home (Fixed Wireless Access) then 10G PON would be required.

Nielsen's Law of Internet Bandwidth is also quoted a few times in the webinar which is another motivator for MNOs to start planning their move to 10G PON. You can read about different Tech Laws for our Industry on 3G4G Blog here.

Anyway, the IHS Markit Webinar 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
