300-430 Question 114
Select 2A retail organization wants to implement an RFID tracking solution to monitor the location of inventory items in real-time within its distribution center. Which wireless network configurations should be prioritized to ensure accurate tracking of RFID tags?
- A
Optimize the wireless network for high-density deployments with multiple access points.
- B
Enable location tracking services on the wireless LAN controller (WLC).
- C
Configure RFID readers with sufficient overlapping coverage in the required areas.
- D
Set access points to operate exclusively on the 5 GHz band for better throughput.
- E
Ensure that access points support Wi-Fi 6 (802.11ax) technology for higher speeds.
Show answer and explanation
Correct answers: B, C
Explanation
To ensure accurate RFID tag tracking, the wireless network should prioritize enabling location tracking services on the wireless LAN controller (WLC) and configuring RFID readers for sufficient overlapping coverage. These configurations ensure that RFID tags are continuously detected and their positions can be accurately determined.
- A. Incorrect.
While optimizing for high-density deployments is important for environments like offices or stadiums, it is not specifically tailored to RFID tracking requirements, which depend more on location accuracy and coverage.
- B. Correct.
Location tracking services on the WLC are critical for RFID tag tracking, as they enable the network to calculate the position of devices using techniques like triangulation.
- C. Correct.
Overlapping coverage from RFID readers is essential to ensure that RFID tags are continuously detected as they move between areas, minimizing blind spots in the tracking system.
- D. Incorrect.
Although the 5 GHz band offers better throughput, RFID tags typically operate at lower frequencies (e.g., 2.4 GHz or proprietary RFID frequencies) and do not benefit from exclusively using 5 GHz.
- E. Incorrect.
Wi-Fi 6 technology enhances throughput and efficiency for high-demand networks, but it is not a requirement for RFID tracking, as RFID tags often operate on non-Wi-Fi frequencies.
