The transceivers utilize a Carrier Sense Multiple Access (CSMA) protocol
with Random Backoff and a programmable back-off seed. Therefore, in
the event of a collision, the transceiver will back off and retry the packet.
Specifically, when two transceivers collide with each other (transmitting
packets at the same time), each transceiver will choose a random number
of packet times that it will wait before retrying the packet. Ideally, they
will each choose a different number and will be successful in the next
transmission. A good rule of thumb is to set Random Backoff to a number
slightly larger than the maximum number of transceivers that would be
expected to be transmitting at the same time.
