Wireless Controller
Load Utilization: This field allows you to set a threshold for the percentage
of network bandwidth utilization allowed on the radio. Once the level you
specify is reached, the AP stops accepting new client associations. Enter a
percentage of utilization from 1 to 100.
Maximum Clients: Specify the maximum number of stations allowed to
associate with this access point at any one time. You can enter a value between
0 and 200.
RF Scan Other Channels: The access point can perform RF scans to collect
information about other wireless devices within range and then report this
information to the DWC-1000 wireless controller. If you select the Scan Other
Channels option, the radio periodically moves away from
the operational channel to scan other channels. Enabling this mode causes the
radio to interrupt user traffic, which may be noticeable with voice
connections. When the Scan Other Channels option is cleared, the AP scans
only the operating channel.
RF Scan Sentry: Select this option to allow the radio to operate in sentry
mode. When the RF Scan Sentry option is selected, 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.
Networks that deploy sentry APs or radios can detect devices on the network
quicker and perform more through security analysis. In this mode, the radio
controllers 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.
Mode: The Mode defines the Physical Layer (PHY) standard the radio uses.
Select one of the following modes for each radio interface.

IEEE 802.11a 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.
IEEE 802.11a/n operates in the 5 GHz ISM band and includes support for
both 802.11a and 802.11n devices. IEEE 802.11n is an extension of the
802.11 standard that includes multiple -input multiple-output (MIMO)
