Abstract:
1. A wireless communications apparatus comprising: a first antenna arrangement configured to transmit and receive communications signals on a first communications channel within a first section of a spatial area around the wireless communications apparatus, wherein the first antenna arrangement is further configured to determine whether the first communications channel is currently being used to carry communication signals before transmitting any communication signals onto the first communications channel, wherein the first antenna arrangement is further configured to selectively and separately manage transmit power levels with wireless devices in the first section of the spatial area around the wireless communications apparatus on a per-wireless device basis; and a second antenna arrangement configured to transmit and receive communications signals on a second communications channel within a second section of the spatial area around the wireless communications apparatus, wherein the second antenna arrangement is further configured to determine whether the second communications channel is currently being used to carry communication signals before transmitting any communication signals onto the second communications channel, wherein the second antenna arrangement is further configured to selectively and separately manage transmit power levels with wireless devices in the second section of the spatial area around the wireless communications apparatus on a per-wireless device basis.
