AMG1302/AMG1202-TSeries User’s Guide

A Basic Service Set (BSS) exists when all communications between wireless stations or between a 
wireless station and a wired network client go through one access point (AP). 

Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic blocking is 
disabled, wireless station A and B can access the wired network and communicate with each other. 
When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired 
network but cannot communicate with each other.

Basic Service set

Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well 
as the cost of buying extra APs, there is also the possibility of channel interference. The AMG1302/
AMG1202-TSeries’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 QoS priorities 
and/or security modes to different SSIDs.

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

• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have different BSSIDs 

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