True, but it dissuades folks from using directional signals, broadcasting RF energy in more directions and increasing the noise floor for everyone. I feel like there should be some sort of middle point here.
- adrian_b 2y agoDirectional signals are easy to use only when both the access points and the wireless stations are in fixed locations. When this is true, it is trivial to use classic directive antennas to achieve very long range communications with standard WiFi. There is no need for expensive phased array antennas. For mobile stations and/or access points, phased array antennas are not enough. See my other reply. WiFi, Bluetooth and the other kinds of communication protocols standardized for use in the unlicensed bands are intended mainly for cheap mobile devices, and mobility at a modest price restricts the antennas to be omnidirectional.
