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

5.8.5 MBSSID
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 LTE
Device’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.
5.8.5.1 Notes on Multiple BSSs
• 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).
• MBSSID should not replace but rather be used in conjunction with 802.1x security.
5.8.6 WiFi Protected Setup (WPS)
Your LTE Device supports WiFi Protected Setup (WPS), which is an easy way to set up a secure
wireless network. WPS is an industry standard specification, defined by the WiFi Alliance.
