350-401 Question 28
Single answerAn enterprise is designing a wireless LAN to include real-time location services (RTLS) for asset tracking within a large warehouse. Which of the following considerations is MOST critical to ensure accurate location tracking when implementing this WLAN design?
- A
Ensure that the WLAN uses at least three access points for triangulation in each coverage area.
- B
Optimize the SSID configuration for higher throughput rather than location accuracy.
- C
Increase the transmit power of access points to maximize coverage across the warehouse.
- D
Place access points only at the perimeter of the warehouse to avoid interference.
Show answer and explanation
Correct answer: A
Explanation
Real-time location services (RTLS) in WLAN design rely on triangulation, which requires at least three access points within the coverage area to calculate the position of devices or assets accurately. Ensuring proper placement of access points for triangulation is a critical component of WLAN design for location services.
- A. Correct.
This is correct because accurate location tracking using RTLS requires at least three access points (APs) per tracked area for triangulation to determine the precise location of devices or assets.
- B. Incorrect.
This is incorrect because prioritizing throughput over location accuracy does not align with the requirements for real-time location tracking. Location services rely on signal strength and triangulation, not throughput.
- C. Incorrect.
This is incorrect because increasing transmit power does not improve location accuracy and can lead to signal overlap, which may degrade the precision of RTLS.
- D. Incorrect.
This is incorrect because placing access points only at the perimeter reduces the ability to triangulate positions accurately within the warehouse.
