By way of introducing an element of future proofing, I run Cat 6A cable ( 10GBASE-T up to 100 metres). It is noticeably stiffer than Cat 6 and requires a larger turning radius, which took some unexpected implementation adjustments, which may render the contractor's objections to 3-inch conduits nugatory.
Virtually all WAP vendors advertise fictional speed/capacity specifications.
They have a system for calculating it.
They calculate the maximum simplex speed for each radio under ideal and theoretical laboratory conditions (WiFi is Simplex) and then add the values together. However, the link between the AP and the switch is Ethernet full duplex. Then when you make adjustments for real world conditions you tend to find that a WAP rated at a 2.53 gbps radio rate is not limited by a 1 Gbps link in the real world.
Having had to audit the December 2016 ITU conference report, I would be overly concerned about 5 GHz use by WiFi; access to that part of the spectrum is sought by a lot of industry sectors and special interest groups, I look forward to obtaining uncontested access to the 60GHz portion of the spectrum. The Koreans and the Japanese are making huge advances in overcming distance limitations. We are probably just as much overdue for a switch from copper to fibre as we are changing from IPv4 to v6.
