300-425 Question 113
Select 4A retail company has implemented Cisco wireless infrastructure to track inventory movement within their warehouse. RFID tags are attached to inventory items, and the wireless network is used to monitor their real-time location. Which of the following conditions must be met to ensure proper tracking of RFID tags in this environment?
- A
The wireless network must support location-based services with appropriate calibration.
- B
The RFID tags must operate in the 5 GHz frequency band to avoid interference.
- C
Access points must be deployed with overlapping coverage to ensure triangulation.
- D
The RFID tags must be active tags capable of transmitting signals to the wireless network.
- E
The wireless controller must have the RFID tracking feature enabled.
Show answer and explanation
Correct answers: A, C, D, E
Explanation
Tracking RFID tags in a Cisco wireless network requires the network to support location-based services with proper calibration, overlapping access point coverage for triangulation, and the use of active RFID tags capable of transmitting signals. Additionally, the wireless controller must have the RFID tracking feature enabled to process the location data. The 5 GHz frequency band is not relevant for RFID tag operation as they use dedicated RFID frequencies.
- A. Correct.
This is correct because location-based services (LBS) require proper calibration of the wireless network to determine accurate positions of RFID tags.
- B. Incorrect.
This is incorrect because RFID tags typically operate on dedicated RFID frequencies, not the 5 GHz band used for traditional Wi-Fi.
- C. Correct.
This is correct because overlapping coverage is necessary for triangulation, which is essential for tracking the location of RFID tags.
- D. Correct.
This is correct because active RFID tags are required to transmit signals to the wireless network for tracking purposes.
- E. Correct.
This is correct because the RFID tracking feature in the wireless controller must be enabled to process and track RFID data.
