300-425 Question 173
Select 4A network engineer is troubleshooting location accuracy issues in a Cisco Hyperlocation deployment. The engineer observes that location accuracy is inconsistent across different areas of the building. Which of the following actions should the engineer take to improve location accuracy?
- A
Verify that the Access Points (APs) are installed in a grid pattern with proper spacing.
- B
Ensure that the antennas on the APs are properly aligned and calibrated.
- C
Check if the Cisco Hyperlocation module firmware is up to date.
- D
Reduce the number of beacons transmitted by the APs to minimize interference.
- E
Adjust the RF calibration model in Cisco Prime or Cisco DNA Center for the specific building layout.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
Improving location accuracy in a Cisco Hyperlocation deployment requires attention to multiple factors, including proper AP placement, antenna alignment, firmware updates, and RF calibration. Each of these plays a critical role in ensuring that the system can accurately calculate the location of devices. Reducing beacon transmissions is counterproductive and can degrade accuracy by limiting the data available for calculations.
- A. Correct.
Proper AP placement in a grid pattern with appropriate spacing ensures maximum location coverage and accuracy. Poor placement can lead to gaps or overlapping coverage, degrading location accuracy.
- B. Correct.
The alignment and calibration of antennas are crucial for accurate signal measurements, which directly impact location accuracy.
- C. Correct.
Outdated firmware on the Cisco Hyperlocation module can lead to bugs or degraded performance, affecting location accuracy.
- D. Incorrect.
Reducing the number of beacons is not recommended as it can reduce the data available for location calculations, leading to reduced accuracy.
- E. Correct.
Adjusting the RF calibration model to match the building layout ensures that the system accounts for environmental factors like walls, furniture, or materials that can affect RF signals.
