Specifications
AP Configuration 29
Transmission Power
By default the handset adapts its output power to the APs, but the output power can be configured
in five steps between 0-20 dBm as well. Make sure that the APs and clients are configured to use
the same output power to avoid asymmetric communication link budgets. The use of anything else
in the APs creates an asymmetric communication link budget and is not recommended.
NOTE: The handset can be configured up to 20 dBm on the a and b/g band (note that between
14-20 dBm no fixed steps can be set because of a power amplifier).

Description
Radio 802.11g With a g only network the stations do not need to use pro-
tection against b only stations. The transmission rate will
be up to 54 Mbps.
802.11b/g Mixed mode where b only and g stations coexist will affect
the g stations to use protection and the throughput will be
decreased.
Transmitting
power
Set to match de-
sired cell size.
The default setting for the handset is Auto power. Auto
power settings for the APs should be used to ensure a
symmetric link.
If the output power is manually set in the AP, make sure the
APs and clients are configured to use the same output
power to avoid asymmetric communication link budgets.
Refer to Section , “Transmission Power”, on page -29.
Radio channel 1, 6, 11
(Option for exist-
ing systems only:
1, 5, 9, 13)
Do not configure a channel for use that is four or less chan-
nels from other channels within the RF range. Doing so will
lower the throughput of the WLAN for the stations within
those channels.
Regulatory do-
main (802.11d)
Enabled
Radio preamble Short Long preamble will work but will decrease overall through-
put when using b data rates
Beacon period 100 ms Higher value will increase battery life and decrease
throughput. Lower value will decrease battery life and in-
crease throughput.
DTIM interval 5 DTIM setting is related to the beacon interval. The value of
5 is recommended when the beacon interval is 100ms.
Antenna diversi-
ty
Enable Disabled antenna diversity may introduce RF shadows at
certain spots.
Short slot time Enable This feature will increase the throughput if no b stations are
associated at the AP.
