Classification: CPC H | IPC H

Claim 16:
17. An apparatus comprising:
a plurality of radio transceivers that provide wireless communication with one or more wireless client devices within a physical space, wherein a plurality of shield wireless transceiver devices are positioned around a perimeter of, or in an arrangement within, the physical space, wherein each of the shield wireless transceiver devices includes one or more directional antennas pointing outward from the physical space so that transmissions from respective shield wireless transceiver devices are strongest in a predetermined area within the physical space or outside of the physical space where shielding is to be achieved for transmissions between the apparatus and the one or more wireless client devices;
a baseband processor coupled to the plurality of radio transceivers; and
a controller coupled to the baseband processor, wherein the controller is configured to coordinate downlink transmissions to one or more wireless client devices and to coordinate uplink transmissions from one or more wireless client devices, wherein the controller is configured to perform a calibration procedure to determine a transmit power to be used for transmissions to or from a given wireless client device of the one or more wireless client devices in order to achieve a desired decoding margin at the given wireless client device or at the apparatus.
