Wireless: Advanced

Beacon Interval

Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a

Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds.

DTIM

A DTIM is a countdown informing clients of the next window for listening to broadcast and

multicast messages. When the wireless router has buffered broadcast or multicast messages

for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect

the beacons and awaken to receive the broadcast and multicast messages. The default value is

1. Valid settings are between 1 and 255.

Fragmentation Threshold

Wireless frames can be divided into smaller units (fragments) to improve performance in the

presence of RF interference and at the limits of RF coverage. Fragmentation will occur when

frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at

its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor

performance.

RTS Threshold

When an excessive number of wireless packet collisions are occurring, wireless performance

can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol.

The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame size
