This assumption seems too stoichastic. Reading 802.11-2007 section
11.1.2.2, it doesn't seem that we're guaranteed to always receive
beacons from all stations. Stations will cancel their pending beacon
transmission if they receive a beacon before their random delay times
out. In the extreme case where the number of stations is very large, it
seems possible that you may never hear beacons for some stations.
