WLAN—Advanced Access Port Settings
8.Set the Access Port beacon settings by clicking on the Beacon Settings button. The following window appears.
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 |
| 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 |
| 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 |
| audio and video applications that are |
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 |
| audio and video applications that are |
