What transmission technique helps WiMAX use the channel bandwidth more efficiently?
A) latency
B) automatic repeat requests
C) FEC
D) adaptive modulation

Question

Quizplus · Accepted Answer

Adaptive modulation helps WiMAX use the channel bandwidth more efficiently by adjusting the modulation scheme and coding rate based on the quality of the wireless channel. This allows for higher data rates in good channel conditions and more reliable connectivity in poor channel conditions. Latency, automatic repeat requests, and FEC are important techniques but do not directly contribute to efficient use of channel bandwidth in WiMAX.
