CTS 308: Reduced Neighbor Report

Jiri Brejcha joins us on this episode to discuss his testing of 6 GHz capable clients (iPad and Google Pixel) and how they discovery 6 GHz Wi-Fi networks. Jiri demonstrates how important the Reduced Neighbor Report plays an important role in 6 GHz AP discovery.
Jiri is an enterprise architect at Cisco UK and part of the Cisco Live team. He’s also a core member of the WLAN Pi team.
In his lab, he has a Cisco 6 GHz access point broadcasting a few SSIDs on different bands. He wondered how an iPad and Pixel will detect a 6 GHz-only SSID. Do you need to have APs operate on PSC only?
Inside of a beacon frame, you’ll find a Reduced Neighbor Report (RNR) Information Element. The RNR contains important details such as the channel used by neighboring access points. This can be one access point or a group of access points. You’ll find this information in the Neighbor AP Information Fields
Target Beacon Transmission Time (TBTT)

Hey, bss parameters field in tbtt information was introduced in 11 ax.. You can see that in 11ax standard draft

[@AlwinRodrigues-d3h]

Can we update details of 2.4G AP in 5G AP beacon using the concept of RNR
