We manufacture a 2.4 GHz spread spectrum modem designed to sit on moving
vehicles (AGV's).
The range is about 500-1000 feet indoors, 3500 feet outdoors
(20 miles with high gain directional antennas).
It's a full duplex device. With automatic error checking and
retransmitting on faults. Up to 115kbps. It uses an
OEM module from Digital Wireless, check it out at
