Abstract: A method and devices for wirelessly transmitting data are disclosed. Data is transmitted between to mobile devices in dependence on the location of the device. In one embodiment, one or more of the power level of transmission; direction of transmission; encryption; and coding scheme may be controlled at a base station in dependence on the location of the mobile device. Multiple base stations may transmit to a single device. The base station may include one or more directional transmission elements. Location information may similarly be used to control the overall operation of a wireless network. Channel selection, hand-offs and base station selections for communication with a mobile device may all be effected in dependence on information about the location of a recipient mobile device.
