Last Friday the IEEE 802 Executive Committee approved Working Group 802.11’s request to form an Extreme High Throughput (EHT) Study Group. This means there’s sufficient interest to work toward launching a more-formal EHT standard-development project, which will likely happen after the Study Group’s work is complete.

IEEE 802.11 working on successor to 802.11ax
Monday, July 16th, 2018Concurrent multi-band Wi-Fi floated in IEEE 802.11
Wednesday, May 31st, 2017A proposal for concurrent multi-band Wi-Fi was brought into the most recent meeting of working group IEEE 802.11. Similar to how mobile broadband can use multiple bands at the same time, the proposal would allow a Wi-Fi connection to use the 2.4 and 5 GHz bands simultaneously. Data would be split based on instantaneous channel conditions.
IEEE 802 and 3GPP step up collaboration on LAA
Monday, March 23rd, 2015IEEE 802 and 3GPP are working together more on coexistence of Licensed Authorized Access (LAA) and Wi-Fi. Since November, each group has made a presentation to the other. There’s been an exchange of liaison statements, the latest on March 18 when IEEE 802 sent 3GPP two statements containing several requests and recommendations.
FCC to move on 5 GHz, but no faster nor further than NTIA
Friday, February 15th, 2013At its February 20 meeting, the FCC will likely adopt a Notice of Proposed Rulemaking as a first step toward increasing the amount of spectrum available in the 5 GHz band for unlicensed devices. Up to 195 MHz might be made available, which is a 35% increase over the present 555 MHz. Chairman Genachowski announced this initiative at CES in January. A leading application for new spectrum would be IEEE 802.11ac, which could have four instead of the current two 160 MHz-wide channels.
FCC’s 5 GHz spectrum initiative could mean more and wider channels for IEEE 802.11ac
Thursday, January 10th, 2013FCC Chairman Julius Genachowski yesterday announced an initiative to make 195 MHz of more spectrum available for Wi-Fi in the 5 GHz band.
The last time more spectrum for Wi-Fi was made available in this range was in 2003, when an FCC increased the then 300 MHz bandwidth to 555 MHz. As the document in that last link shows, the 5 GHz band is not as neat as the 2.4 GHz band, with other services, such as radar, requiring protection. These coexistence issues will have to be looked at again.
