The mice and keyboards usually have a tranceiver unit, which usually plugs
into a USB port on the computer. Each mouse/keyboard and tranceiver pair
with each other, and will only recognize the paired devices. As an example,
I have two computers in my shack that happen to use identical Dell wireless
mice and keyboards. The two are at most 3 feet away from each other, and
don't interfere at all. Most often, things will work fine out of the box,
but occasionally you'll have to go through a pairing process so that the
transmitters and receivers can "find" each other.

As for RF problems, bear in mind that there is a cable from the transceiver
that gets plugged into the computer. If necessary, ferrites can be put onto
that cable, though I have not had any issues with my setup.
