1. A system, comprising:

  • a single wireless station configured to operate in a packet-switched cellular network, the single wireless station including;

    a first transmission point with a multiple-input-multiple-output (MIMO) capability, the first transmission point having;

    a plurality of first directional antennas,at least one first radio in communication with the first directional antennas, andfirst circuitry in communication with the at least one first radio;

    a second transmission point with a multiple-input-multiple-output (MIMO) capability, the second transmission point having;

    a plurality of second directional antennas,at least one second radio in communication with the second directional antennas, andsecond circuitry in communication with the at least one second radio; and

    third circuitry in communication with the first circuitry of the first transmission point with the multiple-input-multiple-output (MIMO) capability and the second circuitry of the second transmission point with the multiple-input-multiple-output (MIMO) capability;

    said single wireless station configured such that the first transmission point with the multiple-input-multiple-output (MIMO) capability cooperates with the second transmission point with the multiple-input-multiple-output (MIMO) capability in connection with a first transmission to a first multiple-input-multiple-output (MIMO)-capable portable wireless device, for improving the first transmission;

    said single wireless station configured for;

    receiving first information from the first multiple-input-multiple-output (MIMO)-capable portable wireless device that is based on a measurement performed by the first multiple-input-multiple-output (MIMO)-capable portable wireless device;

    receiving second information from the first multiple-input-multiple-output (MIMO)-capable portable wireless device that is based on another measurement performed by the first multiple-input-multiple-output (MIMO)-capable portable wireless device;

    altering at least one aspect of the first transmission in connection with at least one of;

    multiple of the first directional antennas of the first transmission point with the multiple-input-multiple-output (MIMO) capability, or multiple of the second directional antennas of the second transmission point with the multiple-input-multiple-output (MIMO) capability, based on the first information and the second information; and

    transmitting data in connection with the first transmission to the first multiple-input-multiple-output (MIMO)-capable portable wireless device, utilizing at least one of;

    the multiple first directional antennas of the first transmission point with the multiple-input-multiple-output (MIMO) capability, or the multiple second directional antennas of the second transmission point with the multiple-input-multiple-output (MIMO) capability.
