WLAN—Setting Default Access Port Settings
8. 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 |
| |
| 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 |
| |
| |
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 |
