C is correct, hyperlocation is supported started from 8.1 code: https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-2/b_hyperLocation_best_practices_and_troubleshooting_guide.html#id_12803:~:text=Cisco%20WLC%20code%208.1%20(8.1.131.0)%20or%20higher

RRM (Radio Resource Management): After enabling Hyperlocation, the system requires time to stabilize and optimize its operations. This includes RRM settling and the Hyperlocation module calibrating itself to the environment. Waiting 60–90 minutes allows the system to achieve accurate location measurements.

Thanks to largestyle's source I made Deepseek change its answer C. Wait 60 to 90 minutes for RRM to settle before recording location measurements. Explanation: RRM (Radio Resource Management): After enabling Hyperlocation, the system requires time to stabilize and optimize its operations. This includes RRM settling and the Hyperlocation module calibrating itself to the environment. Waiting 60–90 minutes allows the system to achieve accurate location measurements. Why not the other options? A. Open SNMP port 161 and NMSP port 16113 on the WLC: While these ports are necessary for communication, they are not the root cause of poor location accuracy in this scenario. B. Enable Hyperlocation in the Global Configuration settings of the WLC: This is already implied in the scenario, as the WLAN is deployed with Hyperlocation enabled. D. Install the software code for the WLC that supports the Hyperlocation module: AireOS v8.2 already supports Hyperlocation, so this is not necessary.

Second this. From the URL above: Troubleshooting HyperLocation Deployment Issues Hardware Poor location accuracy when packets arrive: Ensure NTP server is up and running. Ensure the same NTP server is used for syncing time for WLC, MSE and PI. Ensure that any tilt of APs is recorded accurately within PI maps. Ensure the accurate azimuth angle is recorded within PI. Allow 60-90 minutes for RRM to settle before recording location measurements.

Not according to the following (trouble shooting section) the answer is to wait 60-90 minshttps://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-2/b_hyperLocation_best_practices_and_troubleshooting_guide.html#id_12692

The Cisco Hyperlocation modules require compatible software code on the WLC to fully support and optimize their functionality. Without the appropriate software code, the WLC may not be able to effectively process and utilize the capabilities of the Hyperlocation modules, potentially leading to poor location accuracy. By installing the correct software code for the WLC that supports the Hyperlocation module, the engineer ensures that the WLC can properly integrate with and leverage the capabilities of the Hyperlocation modules. This should help improve location accuracy and overall performance when utilizing Hyperlocation features in the WLAN environment.
