Express Mode - Alcatel-Lucent Stellar AP Series Deployment & Configuration & Troubleshooting Manual

for all APs in a facility. This minimizes the chance of higher-power APs interfering
with nearby lower-power APs and provides consistent coverage.
It is recommended to set AP power output to 100 mW. If this cannot be
accommodated, use a 50 mW setting or a minimum of 30 mW. With lower power
output settings, special attention must be made to AP placement to ensure there are
no frequency reuse issues. Regardless of the selected power level settings, all APs
and handsets must be configured with the same settings to avoid channel conflicts
and unwanted cross-channel interference.
In mixed 802.11b/g environments, set the power of the 802.11b and 802.11g radios
to the same setting, if they are separately configurable. For example, set both radio
to 30mW to ensure identical coverage on both radios. For mixed 802.11a/b/g
environments, where the AP uses all three radios types, AP placement should first be
determined by modeling for the characteristics of 802.11a, since this environment
will typically have the shortest range. Then, the transmission power of the 802.11b
and 802.11g radios should be adjusted to provide the required coverage levels for
those networks, within the already established AP locations.
Where possible, all APs should be set to the same transmission power level within a
given radio type. For example, set all 802.11a radios to 50 mW and set all 802.11b
and 802.11g radios to 30 mW. It crucial to then set the transmission power of the
handset to match the transmission power of the APs. This will ensure a symmetrical
communication link. Mismatched transmission power outputs will result in reduced
range, poor handoff, one-way audio and other QoS issues.

3.2 Express mode

Stellar APs, by default, are running in "Express mode". To configure the AP out-
of-box, connect the AP to the network and powered by POE or power adapter, and
ensure the AP could retrieve an IP address from the network.
