Abstract:
1. A method, for controlling access priority to a radiofrequency (RF) channel between at least one first wireless device associated with a first wireless access point having a first RF coverage area and at least one second wireless device associated with a second wireless access point having a second RF coverage area, wherein said first RF coverage area and said second RF coverage area overlap in an overlap RF coverage area, wherein said at least one first wireless device and said at least one second wireless device are located within said overlap RF coverage area, and wherein said at least one first wireless device and said at least one second wireless device access said RF channel via a collision sense multiple access/collision avoidance (CSMA/CA) mechanism, said method comprising the steps of: transmitting to said at least one first wireless device a first message comprising a first set of lengths of first interframe spacings and a first set of maximum lengths of first contention windows; and transmitting to said at least one second wireless device a second message comprising a second set of lengths of second interframe spacings and a second set of maximum lengths of second contention windows; wherein said first set of lengths of first interframe spacings, said first set of maximum lengths of first contention windows, said second set of lengths of second interframe spacings, and said second set of maximum lengths of second contention windows are configured such that the probability of said at least one first wireless device accessing said RF channel is greater than the probability of said at least one second wireless device accessing said RF channel; wherein said step of transmitting to said at least one first wireless device a first message comprises the step of:
