300-430 Question 172
Single answerAn enterprise is using Cisco Hyperlocation to enhance location accuracy for asset tracking within a large warehouse. Recently, users have reported that the system's location estimates for devices are often inaccurate. Upon investigation, you discover that some Access Points (APs) are not reporting RSSI (Received Signal Strength Indicator) data properly. What is the most likely cause of this issue?
- A
The APs are not configured with the correct antenna patterns for Hyperlocation.
- B
The devices being tracked do not support 802.11ac Wave 2.
- C
Interference from nearby Bluetooth Low Energy (BLE) devices is disrupting Hyperlocation functionality.
- D
The configured transmit power levels of the APs are inconsistent across the deployment.
Show answer and explanation
Correct answer: D
Explanation
Cisco Hyperlocation relies on consistent RSSI data from Access Points to calculate precise device locations. If the transmit power levels of APs are unevenly configured, it can result in inaccurate RSSI readings, causing degraded location accuracy. Ensuring consistent power levels across all APs in the Hyperlocation deployment is critical for optimal location accuracy.
- A. Incorrect.
Incorrect antenna patterns can affect signal coverage, but they are not the primary factor in Hyperlocation RSSI reporting issues.
- B. Incorrect.
While device compatibility is important, the lack of 802.11ac Wave 2 support would not directly cause RSSI reporting problems for Hyperlocation.
- C. Incorrect.
BLE interference can cause disruptions, but it is unlikely to directly affect RSSI data for Hyperlocation.
- D. Correct.
Inconsistent transmit power levels across APs can lead to uneven RSSI data collection, directly impacting Hyperlocation's ability to provide accurate location estimates.
