Which of the following best defines the term Hopping used in Frequency Hopping wireless LAN systems?

Switching throughput speeds between 11 Mbps to 5.5 Mbps
FHSS feature where the carrier frequency is changed
Change that occurs as a result of the RF signal getting weaker
Change in transmission technology from FHSS to DSSS

Explanation

Answer - B - Hopping is a FHSS feature where the carrier frequency is changed.

Key Takeaway: Frequency hopping is a modulation technique used in spread spectrum signal transmission. Hopping periodically switches the transmission frequencies during radio transmission to minimize unauthorized interception or jamming. It also is known as frequency- hopping code division multiple access, or FH-CDMA. When a FHSS system hops, both the transmitter and receiver systems change the carrier frequency in a synchronized fashion.
