4 - Configuring the Radios
102
Basic Rate
Choose the rate at which the access point transmits multicast and
beacon frames. In general, higher speeds mean shorter range and
lower speeds mean longer range. Do not set this rate higher than
the maximum rate at which your end devices can receive
multicast frames. You can set this rate to 24, 12, or 6 Mbps. This
parameter should usually be left at the default of 6 Mbps.
Reservation Threshold
You may need to set a threshold value, which is the largest data
frame that can be transmitted without reserving air time. Air time
is normally reserved to help prevent collisions with other
transmitters. If you set this threshold to 2347, this parameter is
disabled.
Fragmentation Threshold
Specifies the largest data frame that can be transmitted without
fragmentation. On certain radios, the fragmentation does not
occur unless the radio detects interference. Larger frame sizes can
improve throughput on a reliable connection. Smaller frame sizes
can improve throughput on a poor connection.
Disallow Network Name of ‘ANY’ (Master radio only)
Determines if end devices that have their SSID (Network Name)
set to ANY or are left blank can associate with this access point.
Clear this check box to allow these end devices to associate with
this access point. This setting is 802.11a compliant, but not very
secure.
Check this check box to prevent end devices with an SSID of ANY
or are left blank from associating with this access point.
Beacon Period
Specifies how often the access point sends out a beacon frame.
This rate is in TU. A TU is 1024 microseconds, and is often
considered to be equivalent to one millisecond.
DTIM Period
Specifies the number of beacon periods to skip before including a
DTIM (delivery traffic indication message) in a beacon frame.
Setting a higher DTIM period may conserve battery life in an end
device, but it may increase response time.
