NWA1100-N User’s Guide

The IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended 
authentication as well as providing additional accounting and control features. Your NWA can 
support 802.11b/g and 802.11b/g/n.

Traditionally, you needed to use different APs to configure different Basic Service Sets (BSSs). As 
well as the cost of buying extra APs, there was also the possibility of channel interference. The 
NWA’s MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one access point to 
provide several BSSs simultaneously. You can then assign varying levels of privilege to different 
SSIDs.

Wireless stations can use different BSSIDs to associate with the same AP. 

The following are some notes on multiple BSS. 

• A maximum of four BSSs are allowed on one AP simultaneously.
• You must use different WEP keys for different BSSs. If two stations have different BSSIDs (they 

are in different BSSs), but have the same WEP keys, they may hear each other’s communications 
(but not communicate with each other).

• MBSSID should not replace but rather be used in conjunction with 802.1x security.
