• Bandwidth Utilization — How much of the radio bandwidth can be used
before the WAP device stops allowing new client associations. The valid
integer range is from 0 to 100 percent. When set to 0, all new
associations are allowed regardless of the utilization rate. The default is
0.
• Maximum Associated Clients —The maximum number of stations allowed
to access each radio of this WAP device at any one time. You can enter an
integer between 0 and 200. The default is 200 stations. The dual-radio
WAP571/E device can support up to 400 clients total.
• Transmit Power —A percentage value for the transmit power level for this
WAP device.
The default value of 100 percent can be more cost-efficient than a lower
percentage because it gives the WAP device a maximum broadcast range
and reduces the number of access points needed.
To increase the capacity of the network, place WAP devices closer together
and reduce the value of the transmit power. This helps reduce overlap and
interference among access points. A lower transmit power setting can also
keep your network more secure because weaker wireless signals are less
likely to propagate outside of the physical location of your network.
Some channel ranges and country code combinations have relatively low
maximum transmit power. When attempting to set the transmit power to the
lower ranges (for example, 25 percent or 12 percent), the expected drop in
power may not occur, because certain power amplifiers have minimum
transmit power requirements.
• Frame-burst Support — Generally enabling Frame-burst support
improves the radio performance in the downstream direction.
• Fixed Multicast Rate —The transmission rate in Mbps for broadcast and
multicast packets. This setting can be useful in an environment where
wireless multicast video streaming occurs, provided the wireless clients are
capable of handling the configured rate.
When Auto is selected, the WAP device chooses the best rate for the
associated clients. The range of valid values is determined by the configured
radio mode.
• Legacy Rate Sets —Rates are expressed in megabits per second.
