Using Multiple Antennas (MIMO)
802.11n radios can use up to 3 antennas at a time. MIMO antennas contain three
antennas within a single enclosure, providing three antenna connections to the
radio. You can use these antennas for several purposes depending on the
configuration.
You can use multiple antennas to:
send more data simultaneously (streams)
1 Antenna 2 Antennas 3 Antennas
1 Stream 1 Antenna - Stream 1 2 Antenna - Stream 1 3 Antenna - Stream 1
2 Streams N/A 1 Antenna - Stream 1
1 Antenna - Stream 2 1 Antenna - Stream 1
2 Antenna - Stream 2
improve the ability of the radio to receive weak signals, therefore giving better
range.
