Reliable wireless microcontroller communication

RF transmitters and receivers

315MHz and 415MHz transmitters and receivers

As you probably know, there are some pretty cheap RF transmitters and receivers around.  For something like $10 you can get a transmitter/receiver pair and get one-way communication link going.

With most RF projects like that you will need to implement some level of error correction. In most cases a simple checksum is enough, but there are situations where it is necessary to implement a full reliable wireless communication protocol guaranteeing that the message is transmitted properly.

This Arduino project utilises a couple of the aforementioned cheap RF transmitters and receivers, establishing a two-way link  on different frequencies and describes the synchronization protocol.
