(frequency-hopping spread spectrum) is a modulation technology used in wireless netwok transmissions. It also is known as frequency-hopping code division multiple access (FH-CDMA). In FHSS, the data signal "hops" between available frequencies several times per second, according to a specified algorighm. The transmission is synchronized between the sender and the receiver. Benefits include improved privacy, decreased narrowband interference, and increased signal capacity. See also: DSSS FIPS
A form of spread-spectrum technology used in radio transmissions, which enables simultaneous transmission of multiple signals over a single radio frequency band. With FHSS, a radio signal "hops" between frequencies within the band. Originally developed by the U.S. military to prevent eavesdropping and radio jamming, FHSS now commonly used in wireless local-area networks (WLANs). Another common WLAN option is direct-sequence spread spectrum (DSSS). See DSSS and WLAN.
A technique used in spread spectrum radio transmission systems, such as wireless LANs and some PCS cellular systems, that involves the conversion of a datastream into a stream of packets.
