Web: Configuring Advanced Radio Settings
The Radio – Advanced Settings pop-up window, shown in Figure 6-3, enables
you to configure a number of advanced settings for the access point’s radio
operation:
■ Broadcast/Multicast Rate Limiting: Enables the rate limiting on the
radio to transmit multicast and broadcast traffic. Using this parameter
enables the Rate Limit and Rate Limit Burst fields. (The default is
Disabled.)
• Rate Limit: The broadcast/multicast rate limit value in packets per
second. Valid values are any number greater than 0. (The default is 50.)
• Rate Limit Burst: The broadcast/multicast rate burst value in
packets per second. This value specifies the length of time allowed
for a packet burst. Valid values are any number greater than 0. (The
default is 75.)
■ Antenna Type: The type of radio antenna utilized by this access point.
(The default is Internal) For the configuration details, see
“Web: Setting the
Antenna Type and Antenna Mode” on page 6-25.
■ Protected Mode: Enables/disables the protection mode on the radio.
(The default is Enabled.)
■ Antenna Mode: The mode of radio antenna utilized by this access point.
(The default is Diversity.) For the configuration details, see
“Web: Setting
the Antenna Type and Antenna Mode” on page 6-25
.
■ Preamble: Sets the length of the signal preamble used at the start of a
data transmission. Using a short preamble can increase data throughput
on the access point, but requires that all associated stations be able to
support a short preamble. (The default is Long.)
• Long: Ensures that the access point can support all 802.11b and
802.11g stations.
• Short: Sets the preamble according to the capability of stations that
are currently associated. Uses a short preamble if all associated
stations can support it; otherwise a long preamble is used.
■ RTS Threshold: Sets the packet size threshold at which a Request to Send
(RTS) signal must be sent to a receiving station before the sending station
starts communications. The access point sends RTS frames to a receiving
station to negotiate the sending of a data frame. After receiving an RTS
frame, the station sends a CTS (clear to send) frame to notify the sending
station that it can start sending data. (The default is 2347.)
■ Slot Time: Sets the basic unit of time the access point uses for calculating
waiting times before data is transmitted. (The default is Short.)
