I also think 802.11Ay is the way forward, after all, as described below

Some of the key new features in the 11be technology, such as the 320 Mhz uhf bandwidth, will have to be implemented in the new 6 Ghz Wireless Band. This means that 11be doesn't have maximum speed on WiFi6 compatible bands, and that 11be's true full speed wireless bands don't actually go down to previous Wi fi standards. And that complicates things. Because if the next-generation "WiFi7" standard is destined to speed things up by introducing new wireless bands that are different from the old ones, then 11be isn't the only option, or even the best option. Because there's a faster wi-fi technology, called ieee 802.11Ay, that uses the 60 Ghz ultra-high wireless band and is designed for future indoor applications such as 8K video streaming and wireless VR head displays, and its single data stream (single antenna) bandwidth can be up to 44 GBPS, maximum support four data streams concurrently, that is, 176 gbps bandwidth. Note that 11be requires up to 16 concurrent data streams to reach the rumored "30 gbps, " which means that 802.11 Ay is 23.5 times faster than 802.11 be for single-antenna devices only. So how can we be sure that the slower 11be technology will be the WIFI7 of the future? Why do we say that? This actually stems from two "important new features" of the 11be technology. One is to double the number of concurrent data streams (MIMO) from a maximum of 8 to a maximum of 16 in this generation, and the other is to add a new "collaborative multi-user multi-input multi-output (cmu-MIMO) " function. More tellingly, the 11be era requires a super wireless card with 16 antennas to really enjoy the 30 gbps of bandwidth that the technology claims, then there is the need to buy a wireless router with 16 antennas (32 if the transmitter and receiver are separated, and 96 if the frequency bands are further separated) . And if you can't afford a single router, the 11be technology allows you to buy two sub flagships with half an antenna each, and then they can work together to achieve antenna concurrency.

FACEBOOK (Facebook) and the wi-fi technology alliance promote 802.11Ay, and the digest proves it.
