3. Configure the Radio Settings field to assign a channel, antenna diversity setting, radio
transmit power level and data rate.
ERP Protection Extended Rate PHY (ERP) allows 802.11g MUs to interoperate with
802.11b only MUs. ERP Protection is managed automatically by the
access point and informs users when 802.11b MUs are present
within the access point’s coverage area. The presence of 802.11b
MUs within the 802.11g coverage area negatively impacts network
performance, so this feature should looked to as an indicator of
why network performance has been degraded.
Channel Setting The following channel setting options exist:
User Selection - If selected, use the drop-down menu to specify
the legal channel for the intended country of operation. The drop-
down menu is not available if this option is not selected.
Automatic Selection - Enables the
access point to auto-select
the channel of operation. For example, if three access point’s are
operating on 802.11b/g, each access point would be set to a non-
overlapping channel (1, 6 and 11). If using the access point’s
802.11a radio, a Uniform Spreading option is available (and is
the default setting for the 802.11a radio). To comply with Dynamic
Frequency Selection (DFS) requirements in the European Union, the
802.11a radio uses a randomly selected channel each time the
access point is powered on.
Antenna Diversity Specifies the antenna selection for the 802.11a radio. Options
include Primary Only, Secondary Only and Full Diversity. The default
setting is Primary. However, Diversity can improve performance
and signal reception in areas where interference is significant and
is recommended when two antennas are supported.
Power Level The Power Level parameter defines the transmit power of the
802.11a or 802.11b/g antenna(s). The values are expressed in dBm
and mW.
