Abstract
A system, method, and computer program product is provided to select at least one channel based on one or more channel characteristics and initiate a first transmission to a first multiple-input-multiple-output (MIMO)-capable portable wireless device, and further initiate a second transmission to a second multiple-input-multiple-output (MIMO)-capable portable wireless device, such that at least a portion of the first transmission occurs simultaneously with at least a portion of the second transmission and both occur via a first wireless protocol; and is further configured to initiate a third transmission to a third multiple-input-multiple-output (MIMO)-capable portable wireless device via a second wireless protocol including a 802.11n protocol, where the first wireless protocol includes another 802.11 protocol other than the 802.11n protocol.
