Maximum Associated Clients—The maximum number of stations allowed to access 
this WAP device at any one time. You can enter an integer between 0 and 200. The 
default is 200 stations.
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% or 12%), 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.
Supported Rate Sets indicate rates that the WAP device supports. You can check 
multiple rates (check a box to select or deselect a rate). The WAP device automatically 
chooses the most efficient rate based on factors such as error rates and the distance of 
client stations from the WAP device.
Basic Rate Sets indicate rates that the WAP device advertises to the network for the 
purposes of setting up communication with other access points and client stations on the 
network. It is generally more efficient to have a WAP device broadcast a subset of its 
supported rate sets.
MCS (Data Rate) Settings—The Modulation and Coding Scheme (MCS) index values 
that the WAP device advertises. MCS can enhance throughput for 802.11n wireless 
clients.
