Good summary of IEEE 802.11 Fall Plenary Session by Rolf, cheers!
With over 500 people joining IEEE802.11 sessions this week, it is becoming crunch time for the development of the 802.11bn 'Ultra High Reliability' future Wi-Fi 8 standard. The physical meeting took place in Kona, Hawaii. In .11bn some good progress on Multi AP technologies (e.g. Coordinated TDMA and r-TWT), Unequal Modulation, AP Power Save, in device coex and others. 802.11be (Wi-Fi 7) is ready for final approval by the IEEE SA Standards Board later this month. The Enhanced Light Communication Study Group held its first meeting. The Ambient Power group (.11bp) reviewed submissions regarding its 4 types of use cases and had a dedicated session on Wireless Power Transfer. The 320 Mhz ranging group (.11bk) is ready for the SA balloting phase.

As far as I know, this is very first work of analysis for FR3 spectrum issues in Japan region. Quite valuable output.
Professor, Kyoto University | Executive research director, NICT, Japan | IEEE Fellow | IEICE Fellow
Our team at Kyoto University shows that there is an excellent possibility that 5G can be operated as a spectrum-sharing system in the 15 GHz band of the frequency range 3 (FR3) in Japan. First, we considered how much spectrum resource can be secured in the 15 GHz band in Japan and show that it can ensure a 550 MHz bandwidth in many places and a 190-510 MHz bandwidth in urban areas. Next, we evaluated the 5G block error rate characteristics of various subcarrier spacings (SCSs) using link-level simulation with a phase noise model for the 15 GHz band, Finally, the interference immunity of the 5G NR was evaluated, and it was found that the required SIR is approximately 10 dB and that each 5G base station could achieve coverage of approximately 700 m in radius. As it is a preprint paper of the IEEE, anyone can read the article, even if they are not a member of the IEEE. Please read the article and show your impression. https://lnkd.in/gBiAfMhM

Wi-Fi Gets Wider With Wi-Fi 7. Unlike previous generations Wi-Fi 7 (aka IEEE 802.11be) is the first standard to use OFDMA to actively aggregate the new 6 GHz band with the 2.4, and 5 GHz bands to achieve a significant increase in data throughput. https://buff.ly/49bfY0E

Points for Microwave Tx: 1- Each modulation order has specific signal to noise ratio target should be reached 2- As order of modulation increases , Target SNR increases too 3- As order of modulation increases , link capacity increases 4- That happens because number of symbols and bits per symbol increases over the carrier 5- Bit error rate probability increases too as with higher modulation order 6- Usually we use digital modulation QAM 7- Microwave Links are capable to send Traffic with modulation from QPSK till 4096 and 8192 QAM 8- That means up to 13 bit per symbol 9- When the channel conditions changed order should be changed too modulation 10- In adaptive modulation, Modulation can be up shifted or downshifted 11- In fixed modulation , order of modulation and capacity will remain constant 12-Fixed modulation can be used with TDM traffic like E1 STM-1 to carry 2G voice for example 13- Adaptive modulation commonly used with hybrid and all packets Traffic 14- Hybrid traffic = TDM traffic & Ether Traffc 15- Pesudo wire can carry encapsulated TDM Traffic over packet switching networks and its widely used with all packet networks

If I asked you how a 1000BASE-T PHY detects link down, what would you say? Most likely, just like me, you only have a limited view of what goes on in the PHY. What I found was that there were no books or online literature covering it either. Thanks to Peter Jones I was able to get in touch with George Zimmerman who knows a great deal about PHYs. I'm really happy to have written this blog post as this is unique material and it's completely free. The IEEE 802.3 standard does not actually define much on what goes on in link monitor, the process that monitors the link. This is left to the implementer of the PHY. Still, there are things in the standard that you should be aware of in the standard such as the minwait and maxwait timer, the loc_rcvr_status and rem_rcvr_status as well as scr_status. There's also a lot of more sources of interference than you would expect. This is also relevant to being able to interpret the signal. So what does the PHY take into consideration for bringing a link down and how long does it take? In the post I cover things such as energy detect, MSE, and FCS. I think you will find it informative! Happy reading! Link in the comments below 👇

Another fantastic post by Daniel Dib, this time, relating to the in-depth details of how Ethernet PHY detects link down. Don't miss this post, and the previous ones on Daniel's blog.

It shouldn’t be a shock when you hear of new levels of bandwidth for some system or other, but somehow it always is to me. This time, when I saw that the chair of the IEEE802be & bn, Dr. Alfred Asterjadhi, would be giving a webinar I googled things. Of course, I’d heard of WiFi 7, and knew this would have enormous bandwidth, and it was no surprise that there would be talk of WiFi 8 by now; but to see numbers like 23 GBPS and 100 GPBS in black and white [https://lnkd.in/gZwxchRM] in relation to WiFi was a shock nonetheless. I will definitely be watching. Wired and wireless systems never stand alone in isolation, and developments in one naturally spur developments in the other. UWBX Ltd are proud of our achievements in developing isolating transformers for twisted pair Ethernet with ever greater bandwidth [https://lnkd.in/gzx_Ja9y], [https://lnkd.in/gqrVjZke], but will not be sitting on our laurels. It is imperative that twisted pair communications develop to support a future with EHT wireless. Whether EHT SPE grows into a role for this out of developments for automotive [https://lnkd.in/gQabin7t] or not, UWBX Ltd intends to deliver the bandwidth necessary in isolating transformers to support an EHT future for twisted pair Ethernet.
IEEE Computer Society webinar about IEEE 802.11be (Wi-Fi 7) July 30, 2024 IEEE Std 802.11be is the latest step in a journey of continuous innovation in the wireless local area networks (WLAN) standards and is the underlying technology of the latest Wi-Fi 7 products. The goal of the project is to enable wireless communications with extremely high throughput (EHT) and reduced worst case latency, while ensuring backward compatibility with legacy devices operating in the 2.4 GHz, 5 GHz, and 6 GHz bands. In this webinar, Dr. Alfred Asterjadhi, Chair of IEEE 802.11be and IEEE 802.11bn, will present an overview of the features and optimizations introduced by IEEE 802.11be to the Physical layer (PHY) and Medium Access Control layer (MAC), which lead to these improvements.
