Wireless Advanced Setup - Cerio OW-200N2 User Manual

6.4 Wireless 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.
6.4.1 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.
