300-425 Question 174
Select 3A retail company uses Cisco Hyperlocation to track customer movement patterns within their store. However, the accuracy of the location tracking has been inconsistent. During troubleshooting, which actions should you take to improve location accuracy?
- A
Ensure that Access Points (APs) with Hyperlocation modules are installed in a grid-like pattern with proper density.
- B
Verify that the AP transmit power levels are set to the maximum to cover the entire store.
- C
Check that the Hyperlocation antennas are properly aligned and calibrated.
- D
Enable and validate the presence of at least three APs with line-of-sight coverage for each tracked device.
- E
Disable the Cisco Hyperlocation feature on all Access Points and rely solely on RSSI for location tracking.
Show answer and explanation
Correct answers: A, C, D
Explanation
To troubleshoot and improve location accuracy with Cisco Hyperlocation, it is essential to optimize AP placement in a grid pattern, ensure antennas are calibrated, and validate that sufficient APs with line-of-sight coverage are available for triangulation. Avoid increasing AP power indiscriminately, as it may cause interference, and do not disable Hyperlocation features, as they provide enhanced accuracy compared to RSSI-based methods.
- A. Correct.
Correct: Proper AP placement in a grid-like pattern with sufficient density ensures better location triangulation and improves accuracy.
- B. Incorrect.
Incorrect: Setting transmit power to maximum can cause interference and reduce location accuracy. Power levels should be optimized based on the environment.
- C. Correct.
Correct: Proper alignment and calibration of Hyperlocation antennas are critical for accurate location tracking as they ensure proper signal interpretation.
- D. Correct.
Correct: At least three APs with line-of-sight coverage are required for accurate triangulation and location determination of the tracked device.
- E. Incorrect.
Incorrect: Disabling Hyperlocation and relying on RSSI significantly reduces location accuracy compared to using Hyperlocation's advanced features.
