Abstract

A method and system reduce interference between overlapping first (150) and second (100) wireless LAN cells in a medium. Each cell includes a respective plurality of member stations (154 and 104) and there is at least one overlapped station occupying both cells (106). An inter-cell contention-free period value is assigned to a first access point station in the first cell (152. The access point (152) transmits a beacon packet containing the inter-cell contention-free period value (124), which is intercepted at the overlapped station (106) where the inter-cell contention-free period value is forwarded to member stations in the second cell (104). A second access point in the second cell (102) can then delay transmissions by member stations in the second cell (104) until after the inter-cell contention-free period expires.
