SolutionIt is possible to
extend the battery life of such devices as wireless hand held scanner
and WiFi Phones by not waking them up too often.
You
can do this by adjusting the DTIM (Delivery Traffic Indication Message)
interval. DTIM will be sent out with beacons at the specified
interval, if set to 1 the AP tells the clients that has gone into sleep
mode that it has to wake up and be ready to receive data, if set to 5,
the client will only wake up and on every 5th beacon. The more
time the clients has to wake up the more battery the client
uses.
The following DTIM setting has yielded good
results for some of our customer:
Ascom: DTIM =
5
SpectraLink: DTIM = 2
Alternate DTIM
settings will effect different devices accordingly. Please
check your your device spec sheet for optimal setting for you particular
device.
