1. A computer-implemented method, comprising:
providing access to a multiple-input-multiple-output (MIMO)-capable access point including:
a plurality of antennas;
circuitry in communication with the antennas; and
at least one radio in communication with the circuitry;
selecting at least one channel based on one or more channel characteristics, for initiating a first transmission to a first portable wireless device and initiating a second transmission to a second 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;
receiving first information from the first portable wireless device that is based on a first measurement performed by the first portable wireless device;
receiving second information from the second portable wireless device that is based on a second measurement performed by the second portable wireless device;
altering at least one aspect of the first transmission, based on at least one of the first information or the second information, so as to reduce interference between the first transmission and the second transmission when the at least portion of the first transmission occurs simultaneously with the at least portion of the second transmission;
altering at least one aspect of the second transmission, based on at least one of the first information or the second information, so as to reduce the interference between the first transmission and the second transmission when the at least portion of the first transmission occurs simultaneously with the at least portion of the second transmission;
transmitting first data in connection with the first transmission to the first portable wireless device, such that the first transmission is transmitted simultaneously with an additional transmission from another multiple-input-multiple-output (MIMO)-capable access point to the first portable wireless device;
transmitting second data in connection with the second transmission to the second portable wireless device;
receiving third information from a third portable wireless device that is based on a third measurement performed by the third portable wireless device;
altering at least one aspect of a third transmission, based on the third information, for further interference reduction; and
transmitting third data in connection with the third transmission to the third 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.
