The correct answer is False. CDMA2000 can work in both TDD and FDD mode.
CDMA2000 is a 3rd generation (3G) cellular technology that was developed by the CDMA Development Group (CDG). It is a successor to the 2nd generation (2G) CDMA technology, and it is based on the IS-95 standard. CDMA2000 can operate in both time division duplex (TDD) and frequency division duplex (FDD) mode.
TDD mode is a type of duplexing in which the uplink and downlink channels are time-shared. This means that the uplink and downlink channels use the same frequency band, but they use different time slots. TDD mode is often used in areas where there is a lot of spectrum congestion, as it allows for more efficient use of the available spectrum.
FDD mode is a type of duplexing in which the uplink and downlink channels are frequency-separated. This means that the uplink and downlink channels use different frequency bands. FDD
