Shannon tells you its a hiding to nothing. If you use say two frequency
bands, you would get better performance just adding them together and
using collision detection.

The radio spectrum is limited and precious. Go up to light frequencies
and there's lots more speed available. But that doesn't punch through
solid walls..

The best bet is to put a wifi point in every room, and feed them all via
cable, and manage them so that StupidDevices™ are only allowed to log on
to the nearest one
