发明名称 Slow hopping data transmitter
摘要 A method and apparatus for coupling data between communication devices in which data is transmitted over unoccupied radio channels. Multiple radio channels are monitored by a first communication device and a radio channel or a sequence of radio channels is assigned that is unoccupied. A message is then transmitted by the first communication device that includes the assigned radio channel or assigned sequence of radio channels. The first communication device then changes the radio channel to the assigned radio channel or the next channel in the assigned sequence of radio channels. The second communication device receives the transmission and also moves to the assigned radio channel or the next channel in the assigned sequence of radio channels. The process is repeated such that transmissions are over unoccupied radio channels. This results in both the first communication device and the second communication device "hopping" from channel to channel for communicating messages.
