The use of multiple antennas on an access point to issue a signal to one or more receivers is enabled by what 802.11 innovation?
A) multiple input-multiple output (MIMO)
B) channel bonding
C) frame aggregation
D) spread spectrum frequency hopping

Question

Quizplus · Accepted Answer

Multiple input-multiple output (MIMO) is the 802.11 innovation that enables the use of multiple antennas on an access point to issue a signal to one or more receivers. MIMO utilizes multiple spatial streams to increase data throughput and improve wireless performance by transmitting data over multiple antennas. The other options (B, C, and D) do not directly relate to the use of multiple antennas.
