Configuring the AP

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.
