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
