Also known as FHSS (frequency-hopping spread spectrum), auto signal hopping refers to the repeated switching of frequencies during radio transmission. Many benefits come from jumping between different frequencies, including improved privacy, decreased interference, and increased signal capacity. Before auto signal hopping, if there was interference or static on your signal, you would have to change the frequency yourself, manually. With auto signal hopping you can enjoy less interference on your signal without having to do any work.
Signal hopping also enables a signal to be transmitted across a frequency band that is much wider than the minimum bandwidth required by the information signal. The transmitter “hops” between available frequencies according to specified sequence of instructions, which can either be random or pre-planned. A short burst of data is transmitted on a narrowband after which the transmitter tunes to another frequency and transmits again.
