4 - Configuring the Radios
88
The network name is case sensitive and can be no more than 32
alphanumeric characters.
Frequency (Master radio only)
Choose the frequency within the 2.4 to 2.5 GHz range that this
access point uses to transmit and receive frames. The available
frequencies are country-dependent and are determined by the
radio. See the Worldwide Frequencies for the 802.11b Radio table.
Configure all access points used in Spain, France, or Japan to a
common frequency. For all other countries, configure all access
points to a common frequency, or select up to three frequencies
that are at least three channels (or 25 MHz) apart. For example,
you could select 2412 MHz, 2437 MHz, and 2462 MHz. You may
want to use a single frequency to isolate the installation to part of
the band; for example, use a single frequency if other wireless
networks or microwave ovens are in the area.
For optimal performance of master radios in the access point that
are in range of each other, configure the frequencies to be at least
five channels apart. For example, configure the frequency to use
channels 1, 6, and 11.
3. Configure the advanced parameters for the radio. These parameters
are described below:
Data Rate
Choose the rate at which the access point transmits data. In
general, higher speeds mean shorter range and lower speeds
mean longer range. You can set this rate to 11, 5.5, 2, or 1 Mbps.
Allow Data Rate Fallback
Determines if you want the radio to drop to a slower data rate
when it has trouble communicating with another radio.
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 11, 5.5, 2, or 1 Mbps. This
parameter should usually be left at the default 2 Mbps.
Enable Medium Reservation
Determines if you want to specify a reservation threshold. Check
this check box to set a threshold value. If you clear this check box,
you may improve network response time in installations that
usually send very small frames or that have no hidden stations.
