@iwod: you seem to know about what you are writing.
I think that the 802.11ax speed benefit cannot be achieved without additional accessible channels in 5 GHz and 6 GHz range because much of the increased speed possibility needs 80MHz or 80+80MHz channel bundling because clients will not get more than 2 antennas in the very near future.
These additional channels cannot be accessed with additional rules and without negotiation with industry. Since Q4/2018 these channel rules started to be discussed in 802.11ax IEEE org.
I think that WIFI6 discussions about 6GHz band implementation rules need some additional time, but 802.11ax Draft5 using current channels will hit market this summer.
Currently we have only 19 20MHz channels in 5GHz band available in EU UNII1/2a/parts of 2c and together with 3 or 4 2,4 GHz channels we have 22-23 available 20 MHz channels.
In US 25 20MHz channels are available and UNII2b and UNI3 bands are discussed to be accessable. Under certain circumstances there would be 37 20MHz channels available only within the 5GHz band; if the three 2,4 GHz channels are counted,we achieve 40 20Mhz channels within current US WIFI.
If the 6GHz band will be opened, then another 48 channels will become available (UNI4/5/6/7) that would sum up to 88 x 20 MHz channels alltogether 44 x 40MHz channels with 600Mbps@2SS or 22 x 80MHz channels with 1,2Gbps@2SS
Supposed that 2SS (spatial streams = antennas) will be the maximum installed at client side 802.11ax could achieve approx. 1 Gbps throughput via WIFI6 in normal office environments if clients use one of 22 possible 80MHz channels with 2SS. In less density environmants as small business offices ther would then be 22 possible 160MHz channels with 2,4 Gbps WLAN speed that is twice the nowadays GbE LAN speed.
Workstations or Backup NAS stations could be connected with 4SS 160MHz channels with maximum 4,8 Gbps if WLAN connectivity is neccesary.
I'm sure that industry has to give an answer to rise connection speed via CAT7 cables to at least 25/40 Gbps to reach USB3 gen2 or TB2/3 speed via Ethernet to keep pace with upcoming WIFI6 speeds.
I think that there has to be one additional simplifying step to be taken. Each client might be able to form its 40/80/160 MHz channel not only through neighboring subchannels but like the 80+80 definition uses 80 MHz channels different than a real 160MHz channel, there should be the possibility to form an 80 MHz channel by negotiating to use 4 randomly chosen 20MHz channels (20+20+20+20) Any of these subchannels should be possible to be changed if connection quality changes or client population rises.
And in 2,4 GHz band only channels 1/6/11 could be set in US and 1/5/9/13 could be set in EU. And no homeuser admin should ever be able to switch his route to odd channels as 2/3/4/5 or 7/8/9/10 in US or 2/3/4 or 6/7/8 or 10/11/12 in EU.
And 3rd) Routers should detect other routers automatically in a building and adjust beamforming and channel setting. Routers could learn from clients because they move around and could have information about signal strength of different in house WIFI6 routers on different channels.
My personal view is, that Draft 4.0 Chipsets (Routers from ASUS, Netgear, Aerohive, TPlink, Aruba, DLink, Cisco based on Qualcom, Intel Broadcom Chipsets) may be firmware updated to Draft 5.0 and Final version.
First mini PCIe versions are announced being shipped in HP Omen notebooks (Realtek) in Q2.2019
I'm curious, if mini PCIe 802.11ax cards will be available for upgrading existing notebooks.
