Which technique can increase performance by sending independent streams of information at the same time over the same frequencies?
A) spatial diversity
B) MIMO diversity
C) transmit beam forming
D) spatial multiplexing

Question

Quizplus · Accepted Answer

Spatial multiplexing allows multiple independent streams of information to be sent over the same frequencies using multiple antennas, increasing performance. Spatial diversity and MIMO diversity also use multiple antennas but do not necessarily send independent streams of information, while transmit beam forming focuses the antenna signal in a specific direction rather than sending multiple streams.
