Abstract
In a wireless communication network, to reduce the polling overhead it is proposed to poll several stations using the same polling frame. In order to be able to poll more than one station in the same frame, an access point can make use of the locations of stations relative to the access point. The location of each station relative to the access point will cause a different propagation delay for radio communications between the station and the access point. Based on the propagation delays, two or more stations may be grouped together for subsequent transmissions to the access point.
