Appendix D:Radio Parameters
TRX7441 802.11b DS SS Radio Parameters
Pwr Saving
When this parameter is enabled (set to “Y”), the radio operates in power saving
mode, utilizing the parameters listed in this sub-menu.
Tx Power
The value assigned to this parameter determines the transmit power level in milli-
watts. Keep in mind that the allowable value may vary from country to country.
Rx Mode
When this parameter is set to
Normal
, the terminal wakes from a sleep or suspend
state each time a unicast, multicast or broadcast is sent over the network. Choosing
Unicast
or
No Multicast
limits the terminal to receiving only one or the other of
these packet types.
Pwr Mode
The value assigned to this parameter determines the operating method the terminal
uses to conserve power. The default value –
CAM
(Constant Awake Mode) – keeps
the Cisco radio (TRX7441) powered up continuously ensuring quicker message
response.
PSP
(Power Save Mode) powers the Cisco radio on and off based on a time algo-
rithm. Packets are retrieved only when the radio is scheduled to be ‘on’. When the
time expires, the radio turns off for the required time and then turns back on again to
retrieve more data.
When ‘Pwr Mode’ is set to
FASTPSP
, the terminal radio switches between
PSP
mode and
CAM
depending on network traffic. The terminal radio switches to
CAM
when retrieving a large number of packets and then switches to
PSP
once the
packets have been received.
