4.4 Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per
requirements properly, not necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings for
the system. Please click on
Wireless -> Advanced Setup and follow the below setting.
4.4.1.1 Beacon Interval : Beacon Interval is in the range of 20~1024 and set in
unit of millisecond. The default value is 100 msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte
frame, called “Beacon”. Beacon is broadcast to all the stations, provides the
basic information of AP such as SSID, channel, encryption keys, signal
strength, time stamp, support data rate.
All the radio stations received beacon recognizes the existence of such AP,
and may proceed next actions if the information from AP matches the
requirement. Beacon is sent on a periodic basis, the time interval can be
adjusted.
By increasing the beacon interval, you can reduce the number of beacons and
associated overhead, but that will likely delay the association and roaming
process because stations scanning for available access points may miss the
beacons. You can decrease the beacon interval, which increases the rate of
beacons. This will make the association and roaming process very responsive;
however, the network will incur additional overhead and throughput will go
down.
