Configuring the AP
74 AP-4131 Access Point Product Reference Guide
Rate Control Defines the data transmission rate,
the defaults are:
•
11 Mbps - Optional
• 5.5 Mbps - Optional
• 2 Mbps - Required
• 1 Mbps - Required.
The defaults allow the AP to automatically select the
the best transmit rate allowed by the conditions.
These settings allow a mixture of
1 Mbps, 2 Mbps, 5.5 Mbps and 11 Mbps radios in
the same network.
Any combination of the data rates can be
selected as Optional, Required or Not Used,
but it is essential to set the lowest selected rate
to Required.
All IEEE 802.11 broadcast and management frames
are sent out on the lowest required data rate.
RTS Threshold Request to send threshold (256 – 2347). Allows the
AP to use RTS (Request To Send) on frames longer
than the specified length.
The default is
2347
Bytes.
Extended Range Enables APs to bridge over long distances using high
gain antennas. The Extended Range setting adds 11
microseconds per mile to the ACK timeout value.
Should be used for coverage areas greater than one
mile. RF propagation through the air is about 5.5
microseconds per mile (one way). Use 11
microseconds as a round-trip value per mile.
