W-CDMA works in FDD mode only.
A. True
B. False
Answer: Option B
Solution (By Examveda Team)
W-CDMA (Wideband Code Division Multiple Access) is a 3G mobile communication technology that utilizes code division multiple access (CDMA) to allow multiple users to share a single frequency band.FDD (Frequency Division Duplex) is a duplexing method where the uplink (from mobile device to base station) and downlink (from base station to mobile device) transmissions occur on separate frequency bands.
The statement "W-CDMA works in FDD mode only" is False.
While W-CDMA is predominantly used in FDD mode, it is also capable of operating in TDD (Time Division Duplex) mode. In TDD, the uplink and downlink transmissions use the same frequency band but are separated in time.
Therefore, the statement is incorrect because W-CDMA's functionality extends beyond FDD to include TDD operation. The flexibility to operate in both modes makes it adaptable to different network deployments and frequency allocation scenarios.
