Re: Why is radio comms so slow?
On wikipedia they state that it is using the ZigBee protocol. I think that is pretty slow but has decent range. Also, they would want something omnidirectional so there is no need to aim antennas, etc. By the time you've done "simple, reliable, omnidirectional, range of up to 1km, etc." the bitrate is going to get quite low.
