ABSTRACT:
A method for arbitrating use of wireless medium for transmission of wireless signals within a selected local geographic region. The selected local geographic region comprises a first set of a plurality of devices to be allowed to transmit wireless signals and a second set of one or more devices to be substantially restricted from transmitting wireless signals. The method includes providing identity information associated with the first set of wireless devices. The method includes transmitting over a wireless medium at least one packet for each of the wireless devices in the first set. The at least one packet for each of the wireless devices includes an identity information, including an address, associated with that wireless device. That wireless device is a recipient of the one packet on the wireless medium. The at least one packet also has a selected value in a duration field of at least the one packet. The selected value is associated with a portion of time for which that wireless device is to be allowed to transmit wireless signals within the selected local geographic region while restricting at least the wireless devices in the second set.
