Hotels generally use dense wall material to reduce audible noise from one room to another.
Concrete is a common material. 20 to 25dB RF loss can be measured through concrete hotel
walls, but actual results may vary.
The worst case would be a client PC sitting approximately midway between two WallPlates on the
same floor. From this location, the client would be within the carrier detect range of multiple
WallPlates.
