Note: MIMO should not be confused with the Diversity feature. While Diversity
is the use of two antennas to increase the odds that a better radio stream is
received on either of the antennas, MIMO antennas radiate and receive multi-
streams of the same packet to achieve the increased throughput.
The Diversity feature is meant to offset the liability of RF corruption, arising out
of multipath, whereas MIMO converts the liability of multipath to its advantage.
Because the 802.11n AP operates with multiple antennas, it is capable of picking
up even the weakest signals from the client devices.
Channel bonding
In addition to MIMO technology, the 802.11n AP makes a number of additional
changes to the radio to increase the effective throughput of the Wireless LAN.
The radios of regular HiPath Wireless APs use radio channels that are 20 MHz
wide. This means that the channels must be spaced at 20 MHz to avoid
