RF Scan Sentry If you select the RF Scan Sentry check box, the radio primarily performs
dedicated RF scanning. The radio passively listens for beacons and traffic
exchange between clients and other access points but does not accept
connections from wireless clients. In sentry mode, all VAPs are disabled.
In this mode, the radio switches from one channel to the next. The length of
time spent on each channel is controlled by the scan duration. The default
scan duration is 10 milliseconds.
RF Scan Sentry
Channels
The radio can scan channels in the radio frequency used by the 802.11b/g
band, the 802.11a band, or both bands. Select the channel band for the radio
to scan.
NOTE: The band selection applies only to radios in sentry mode.
Rate Sets Check the transmission rate sets you want the access point to support and the
basic rate sets you want the access point to advertise.
Rates are expressed in megabits per second.
Basic These numbers indicate rates that the access point will advertise to the
network for the purposes of setting up communication with other APs and
client stations on the network. It is generally more efficient to have an AP
broadcast a subset of its supported rate sets.
Supported These numbers indicate rates that the access point supports. You can check
multiple rates (click a check box to select or de-select a rate). The AP
automatically chooses the most efficient rate based on factors like error rates
and distance of client stations from the AP.
Mode The Mode defines the Physical Layer (PHY) standard the radio uses.
The DWL-3500AP and Radio 1 on the DWL-8500AP use the IEEE 802.11g
mode PHY standard. This mode is a higher speed extension (up to 54 Mbps)
to the 802.11b PHY, while operating in the 2.4 GHz band. It uses orthogonal
frequency division multiplexing (OFDM). It supports data rates ranging from
1 to 54 Mbps. IEEE 802.11b clients can use the 802.11g mode.
Radio 2 on the DWL-8500AP use the IEEE 802.11a mode, which is a PHY
standard that specifies operating in the 5 GHz U-NII band using orthogonal
frequency division multiplexing (OFDM). It supports data rates ranging from
6 to 54 Mbps.
If the radio state is disabled, the mode displays as Off.
Maximum Clients Specify the maximum number of stations allowed to access this access point
at any one time.
You can enter a value between 0 and 256.
