9. Set the beacon values as indicated in the table below.

Beacon Interval

A beacon is a packet broadcast by the adopted access ports to

 

keep the network synchronized. Included in a beacon is

 

information such as the WLAN service area, the access-port

 

address, the broadcast destination addresses, a time stamp,

 

and indicators about traffic and delivery such as a DTIM.

 

Specify a beacon interval in units of 1,000 microseconds (K-us).

 

This is a multiple of the DTIM value, for example, 100 : 10.

 

Increase the DTIM/beacon settings, lengthening the time, to let

 

nodes sleep longer and preserve their battery life. Decreasing

 

this value (shorten the time) to support streaming-multicast

 

audio and video applications that are jitter-sensitive.

DTIM Period

A DTIM is periodically included in the beacon frame that is

 

transmitted from adopted access ports. The DTIM period

 

determines how often the beacon contains a DTIM, for example,

 

1 DTIM for every 10 beacons. The DTIM indicates that

 

broadcast and multicast frames, buffered at the access port, are

 

soon to arrive. These are simple data frames that require no

 

acknowledgment, so nodes sometimes miss them.

 

In this field, the administrator can specify a period for the

 

Delivery Traffic Indication Message (DTIM). This is a divisor of

 

the beacon interval (in milliseconds); for example, 10 : 100.

 

Increase the DTIM/beacon settings, lengthening the time, to let

 

nodes sleep longer and preserve their battery life. Decrease this

 

settings (shortening the time) to support streaming-multicast

 

audio and video applications that are jitter-sensitive.
