for RF communications, I recommend Linx Technologies
http://www.linxtechnologies.com/ They sell seperate transmitters,
receivers, and antennas. For two-way communication, you would need two
pairs, so the price is around $30 for a bidirectional link. They have
speed ranges from 5kbps to 50kbps. I've used their LC parts with the
helical antennas and the work great. The only problem is that they seem
to want you to buy the eval kit for a particular part before they will
sell you additional units, and that's pretty expensive and pretty
useless. The parts are all self contained with the only RF pin being the
antenna, so as long as you mount the antenna close by, you don't need to
worry about special design. I mounted the LCs (which are surface mount)
on a pc board, but for the other parts, the datalines should be able to
handle wirewrapping, though I would solder in the power and antenna
connections and put a bypass cap on the power. You don't wont to recieve
"RF" signals from your microcontroller.
