- Metricom Ricochet: uses 162
channels in the 902-928 MHz band; Every radio listens on its own unique
pseudo-random sequence of channels, changing channel every 25 ms. When
it wants to send a packet to another radio, it consults its internal
tables, predicts that channel that radio will be listening on at that
precise moment in time, and transmits the packet on that frequency. Stanford
has written a Linux driver for sending IP packets.
