If you want extra assurance, Logitech (among others) sell devices with secure
set up where you have to enter a code on the keyboard that ties the device to a
particular computer. If you do this, label the mouse and keyboard so that you
know which computer it belongs to. Use rechargeable batteries, have a minimum
of 8 additional batteries, in the charger, ready to go. In general I found
there is a greater advantage to wireless mice in a lab than wireless keyboard
(thought I have heard that wireless keyboards can be great as a
"Nut-free/Allergy-free" keyboard/mouse for students with sever allergies)
Bluetooth has 79 "channels" available to it and will hop around to find one
without interference. In general if you have fewer than 79 in a 30ft radius,
you should be OK. Though, BlueTooth is in the 2.4GHz range (the same as Wi-Fi)
and overlaps 22 channels with Wi-Fi so that could reduce your pool. It also
means the devices are subject to the same kind of interference (e.g. Microwave
ovens).

Subject: Re: wireless keyboards and mice?
Though getting rid of the wires is great, we ran into some issues with
interference with wireless KB's and Mouse(s) in our lab environment - 20
workstations...
We occasionally had problems where one student was typing something that
appeared on the computer of a student sitting near him/her. Same thing with
mouse movements. The kids got a kick out of 'controlling' another user's
machine. We ultimately went back to wired peripherals as a result.
Just something to look out for...
