Transmit Power; Maximum Station Data Rate; Beacon Interval (20-1000); Dtim Period (1-16384) - Nortel 2221 Product Manual

52 Chapter 3 System Configuration

Transmit Power

Set the signal strength transmitted from the access point. The longer the
transmission distance, the higher the transmission power required. (Default:
100%)

Maximum Station Data Rate

Select the appropriate data rate from the drop-down list for the data transfer speed
running on your network. (Default: 54 Mbps)

Beacon Interval (20-1000)

Sets the beacon signal interval. The beacon signals allow the wireless devices to
maintain contact with each other. They may also carry power-management
information. (Default: 100 TU)

DTIM Period (1-16384)

Sets the Delivery Traffic Indication Message (DTIM) packet interval value. The
DTIM informs the client that the access point has broadcast and multicast traffic
to send. This parameter is necessary to wake up stations that are using Power Save
mode.
The DTIM is the interval between two synchronous frames with broadcast
information. If you set the value to 2, the access point saves broadcast and
multicast packets and forwards them after every second beacon. Having smaller
DTIM intervals delivers broadcast and multicast frames in a more timely manner;
however, by causing stations in Power Save mode to wake up more often, smaller
DTIM intervals drain power faster. Conversely, having higher DTIM values delays
the transmission of broadcast and multicast frames, but the larger DTIM intervals
reduces the power used by stations in Power Save mode. (Default: 5 Beacons)
