Device Configuration
5-43
10.Set or override the following profile WLAN Properties for the selected Access Point radio.
Rate Once the radio band is provided, the Rate drop-down menu populates with
rate options depending on the 2.4 or 5 GHz band selected. If the radio band is
set to Sensor or Detector, the Data Rates drop-down menu is not enabled, as
the rates are fixed and not user configurable. If 2.4 GHz is selected as the radio
band, select separate 802.11b, 802.11g and 802.11n rates and define how they
are used in combination. If 5 GHz is selected as the radio band, select separate
802.11a and 802.11n rates then define how they are used together. When
using 802.11n (in either the 2.4 or 5 GHz band), Set a MCS (modulation and
coding scheme) in respect to the radio’s channel width and guard interval. A
MCS defines (based on RF channel conditions) an optimal combination of 8
data rates, bonded channels, multiple spatial streams, different guard
intervals and modulation types. Clients can associate as long as they support
basic MCS (as well as non-11n basic rates).
Radio Placement Use the drop-down menu to specify whether the radio is located Indoors or
Outdoors. The placement should depend on the selected country of operation
and its regulatory domain requirements for radio emissions. The default
setting is Indoors.
Max Clients Use the spinner control to set the maximum permissible client connections for
this radio. set a value between 1- 128.
Beacon Interval Set the interval between radio beacons in milliseconds (either 50, 100 or 200).
A beacon is a packet broadcast by adopted radios to keep the network
synchronized. Included in a beacon is information such as the WLAN service
area, the radio address, the broadcast destination addresses, a time stamp,
and indicators about traffic and delivery such as a DTIM. Increase the DTIM/
beacon settings (lengthening the time) to let nodes sleep longer and preserve
battery life. Decrease these settings (shortening the time) to support
streaming-multicast audio and video applications that are jitter-sensitive.The
default value is 100 milliseconds.
DTIM Interval Set a DTIM Interval to specify a period for Delivery Traffic Indication Messages
(DTIM). A DTIM is periodically included in a beacon frame transmitted from
adopted radios. The DTIM indicates broadcast and multicast frames (buffered
at the Access Port) are soon to arrive. These are simple data frames that
require no acknowledgement, so nodes sometimes miss them. Increase the
DTIM/ beacon settings (lengthening the time) to let nodes sleep longer and
preserve their battery life. Decrease these settings (shortening the time) to
support streaming multicast audio and video applications that are jitter-
sensitive.
