There have been a few 802.11ad capable ‘prosumer routers’ available for a while, by Asus Netgear and TP-Link, so their makers must be pleased that finally users might seek them out based on that capability.
The high speed of 802.11ad makes it spectrum and time efficient, because to move an amount of data the radio can be off more of the time than a slower radio. Firstly, this means it will not occupy the spectrum (a finite resource) as much of the time. Secondly, it could potentially consume less power – always a good thing, especially for battery powered devices like smartphones.
Perhaps more interestingly, 802.11ad has an inherently short range. For a wireless personal area network (WPAN) this is a good thing. Obviously a WPAN only needs a short range, and if signals travel further than required they again reduce spectrum efficiency, because they occupy spectrum in areas where other WPANs could use it.
