Radio Port Configuration
Configuring Radio Settings
To define the RP placement, follow these directions:
1. Select Network Setup > Radio Adoption Defaults > Configuration, select
the radio type, and click Edit.
2. In the Radio Settings section, select Indoors or Outdoors from the Placement
drop-down menu.
3. Click OK.
Configuring the Desired Channel Selection Method. The 802.11 stan-
dards allow RPs to transmit and receive data on several radio channel frequen-
cies within the frequency specified for a particular mode. For example, the 2.4
GHz range (for 802.11bg) includes 14 channels, some of which are allowed
only in certain countries.
The Wireless Edge Services xl Module allows newly adopted radios to select
a channel in one of two ways:
■ Randomly—When each RP radio is adopted, it automatically selects a
random channel within the acceptable frequencies.
■ Using auto channel select (ACS)—The Wireless Edge Services xl Module
helps radios to select the best channel based on noise and signal
properties.
The default configuration is Random.
To specify how newly adopted radios should select a channel, follow
these steps:
1. Select Network Setup > Radio Adoption Defaults > Configuration, select
the radio type, and click Edit.
2. In the Desired Channel drop-down menu, select Random or ACS.
If you want to set channels manually, then you must do so for particular radios
after they are adopted. (See “Configuring Radio Settings for a Particular
Radio” on page 5-32).
Setting the Desired Radio Power. After you have selected a channel, you
must select the radio power. Available settings are determined by previously
defined channel and location settings. A radio's power determines the broad-
cast radio frequency (RF) signal strength in dBm. It is important to set the
power level to a value that is strong enough to clearly reach all the stations,
but not so strong that the RF signal is garbled, overwhelms stations, or
interferes with other RPs. The maximum broadcast power may also be gov-
erned by local and national restrictions. The optimal power level for a partic-
ular channel is best determined by a site survey prior to installation.
