I need to be able to transmit analog data (1..100khz) over a very short
range (max 2 metres)
reliably and without wires. IR is not a possibility as there are times
when the stations will not be able to "see" each other. Latency must be
much less than 1ms, hence digitising and bluetooth (with its 40..50ms
latency) is out. Several pairs of units may be being used in close
proximity hence single frequency "garage door opener" style devices are
out. Of course it has to run on 3 volts, almost no current and be no
bigger than a quarter. Any chips or modules suitable ?.
cheers
