300-430 Question 170
Select 3A retail store has deployed Cisco Hyperlocation to track assets and customers within its premises. However, the IT team has reported that the location accuracy is inconsistent and often incorrect. During troubleshooting, which of the following steps should the IT team prioritize to improve Hyperlocation accuracy?
- A
Ensure that Access Points (APs) supporting Hyperlocation are evenly distributed across the coverage area.
- B
Verify that the client devices support 802.11v and 802.11k for proper integration with Hyperlocation.
- C
Check for interference from non-Wi-Fi sources, such as microwaves and Bluetooth, which could impact RSSI measurements.
- D
Adjust the AP transmit power levels to the maximum to ensure stronger signal coverage.
- E
Ensure the Cisco Wireless LAN Controller (WLC) is configured with the correct RF calibration model for the environment.
Show answer and explanation
Correct answers: A, C, E
Explanation
To troubleshoot location accuracy issues with Cisco Hyperlocation, it is essential to focus on factors that directly impact signal measurement and environmental calibration. Ensuring proper AP placement, mitigating interference, and using the correct RF calibration model are key to improving Hyperlocation accuracy.
- A. Correct.
Ensuring that APs are evenly distributed helps mitigate coverage gaps and overlapping signals, which are critical for Hyperlocation accuracy.
- B. Incorrect.
While 802.11v and 802.11k can assist in Wi-Fi network performance, they are not mandatory for Cisco Hyperlocation to function properly.
- C. Correct.
Interference from non-Wi-Fi sources can distort RSSI and ToF (Time of Flight) measurements, leading to inaccurate location tracking.
- D. Incorrect.
Setting AP transmit power to the maximum can lead to overlapping coverage and interference, negatively impacting location accuracy.
- E. Correct.
Correct RF calibration ensures that the environment's physical characteristics (such as walls and furniture) are factored into the location algorithm, improving accuracy.
