Abstract
RF shielding techniques are employed to prevent wireless signals transmitted from one machine from reaching another machine using the same frequency range. If the machines are spaced closely together, the wireless signals emitted by one machine may be received by the other, thereby causing interference. In one embodiment, one of the machines is placed in a Faraday cage which prevents it from transmitting wireless signals to, and receiving signals from, the other machine. In another embodiment, machines that use different channels are grouped into a first Faraday cage while machines that use the same channels as the machines in the first Faraday cage are placed in a second Faraday cage. In this manner, the machines in the two cages can reuse the same communication channels while being disposed proximate to each other in the shared space.
