Frequency hopping spread spectrum systems are not required to employ all
available hopping channels during each transmission. However, the system,
consisting of both the transmitter and the receiver, must be designed to comply
with all of the regulations should the transmitter be presented with a continuous
data stream from RFID transponders. In addition, a system employing short
transmission bursts must comply with the definition of a frequency hopping
system and must distribute its transmissions over the minimum number of
hopping channels specified. When a continuous data stream is presented, the
1000 adheres to the 0.4 second dwell time limit per channel for each 20 second
window.
