  11. WLAN access points Fixed ‘seed’ nodes User terminals Ad-hock and sensor networks • Radio relay (mesh) networks are gathering momentum • many are based on 802.11 radio technology and therefore have a low cost base • back-haul is considerably less than for conventional cellular Infrastructure mesh: Relaying between access points only These links are static or slowly changing Mobile mesh: Relaying between all devices with fast dynamic routing
