RF communication using low cost components

Hi

There are some cheap RF RX and TX modules available. Any circuits out there for pic to pic transmission. Need to turn led on or off over distance of about 5 metres.

Just the transmission details I need.

IR...
www.rentron.com
There's some examples somewhere around there.
Might have to have a fairly strong IR LED transmitter though.
