Hi James
Greetings
IE - Information Element could be seen only on Management Frames
Quiet IE
Dynamic frequency selection was needed to avoid certain military radar technologies.To find the presence of radar or other interference,an AP can use the Quiet element to temporarily shut down the channel to improve the quality of measurements.
Beacon Report
The 802.11k protocol allows APs and clients to dynamically measure the available radio resources.The APs and clients can send neighbor reports, beacon reports and link measurement reports to each other.
This allows the APs and clients to take appropriate connection actions like band-steer,move sticky client.
The beacon report requests are sent only to 802.11k-compliant clients that advertise Beacon Report Capability in their RRM Enabled Capabilities IE
Client's 11k Beacon Report to AP
