Wi2Wi, Inc. Doc No. CAS-PDT-DOC Rev.1.3 Datasheet, WLAN Module– W2SW0011U Dated: Jauary 7, 2011 The device automatically wakes up to receive beacons periodically, and if there is no traffic indicated for the device, it will go back to sleep. Power consumption is dependent on the DTIM value of the AP it is connected to. When DTIM=1, the device wakes up every 100ms to receive and acknowledge the beacon from AP to maintain association. 8 Antenna and Clock W2SW0011u’s antenna launch has 50 Ohm impedance.
