Flexibility and mobility are the growing reasons to use wireless LAN which uses radio frequencies for transmitting data. Wireless LANs are established for communicating with one another while on the go.

The data transmitting on one frequency for a specific time limit and jumping randomly to another and transmitting again is the process in FHSS. The RF circuits can utilize class C amplification, efficient non-linear with a normal 1 MHz bandwidth.

FHSS systems are better for use within indoors and in severe multipath environments. This is because of the frequency hopping scheme could defeat the multipath by hopping to a new frequency.
