Information that needs to be measured to optimize the radio network. For example, with 802.11k, stations are able to assess how occupied or idle a frequency channel is. <br> <br> <br> <br> The corresponding request and report mechanisms, and the formats of the frames through which the measurement requests and results are communicated among stations, are defined by the 802.11k amendment.<br> <br> <br> <br> Clause 11.11 in the latest 802.11-2016 standards (p. 1709).<br> <br> <br> <br> Why did we want to talk about 802.11k<br> <br> <br> <br> * It can help client devices to better roam* It has not always been supported on client devices* Clients might lie when they advertise their 802.11k capabilities…<br> <br> <br> <br> What is really happening with 802.11k<br> <br> <br> <br> * Most of the time APs (or WLC) gather client radio information via specific mechanisms* The client devices can also request some information from the infrastructure (APs & WLC)<br> <br> <br> <br> What type of information are we talking about?<br> <br> <br> <br> * Neighbor Reports: clients can request a neighbor report and learn valuable information from the infrastructure. The clients will use this information to take better roaming decisions.* Client Statistics: SNR, RSSI, Data rates, frame transmission, retries and errors can be communicated back to the AP & controller.* Channel Statistics: clients might gather noise-floor and channel-load information and send it to the infrastructure.* Transmit Power Control: this can be used to reduced interferences in both frequency bands<br> <br> <br> <br> Validate that an SSID supports 802.11k<br> <br> <br> <br> * Capture the Beacon Frame* Look for the RM Enabled Capabilities IE* Look for the Neighbor Report Enable bit in the first RM Capabilities section<br> <br> <br> <br> <br> <br> <br> <br> Validate that a client supports 802.11k & Neighbor Reports<br> <br> <br> <br> * Capture the Association Request (look at the profiler tool from WLAN Pi)* Look for the RM Enabled Capabilities IE* RM Capabilities* Neighbor Report Enable Bit sho...
