◆ Long Distance Setting — When you have long-distance links in the wireless
network, some timing parameters require an adjustment to maintain
communications.
Enter the approximate distance (in meters) of the client from the AP. Click on
the “Show Reference Data” button to compute a set of recommended values
for SlotTime, ACKTimeOut and CTSTimeOut. You can use the recommended
values or enter your own values that work for your specific environment.
◆ Set Radio — Sets all entered parameters.
Virtual Access Points (VAPs)
The AP supports up to 16 virtual access point (VAP) interfaces per radio, numbered
0 to 15. Each VAP functions as a separate access point, and can be configured with
its own Service Set Identification (SSID) and security settings. However, most radio
signal parameters apply to all VAP interfaces.
The VAPs function similar to a VLAN, with each VAP mapped to its own default
VLAN ID. Traffic to specific VAPs can be segregated based on user groups or
application traffic. All VAPs can support up to a total of 127 wireless clients,
whereby the clients associate with each VAP the same way as they would with
separate physical access points.
Note: The radio channel settings for the access point are limited by local
regulations, which determine the number of channels that are available. See
“Operating Channels” on page 46 for additional information on the maximum
number channels available.
