300-425 Question 111
Select 3A retail chain wants to track the movement of inventory throughout their distribution centers using RFID tags. They plan to integrate the system with their Cisco wireless network for real-time tracking within their facilities. Which factors must be considered when deploying RFID tags for tracking purposes in this environment?
- A
The frequency band compatibility of RFID tags with the wireless network
- B
The mounting height of wireless access points to ensure proper RFID tag communication
- C
The power source and battery life of RFID tags used for tracking
- D
The encryption standard supported by RFID tags for secure tag-to-reader communication
- E
The maximum number of RFID tags that can be tracked simultaneously by the Cisco wireless system
Show answer and explanation
Correct answers: A, B, E
Explanation
When deploying RFID tags for tracking purposes, it is important to ensure that the tags operate on a compatible frequency band with the existing wireless network. Additionally, the placement of access points plays a critical role in enabling effective tag detection. Finally, the capacity of the Cisco wireless system to handle a large volume of tags is important for ensuring scalability in environments like distribution centers. Battery life and encryption, while important in other contexts, are less relevant for tracking-only RFID tags in scenarios focused on inventory movement.
- A. Correct.
RFID systems operate on specific frequency bands (such as LF, HF, UHF), and compatibility with the wireless network is essential to ensure proper function and avoid interference.
- B. Correct.
The placement and height of access points can significantly impact the ability of RFID readers or antennas to detect and communicate with tags effectively.
- C. Incorrect.
While battery life is important for active RFID tags, many tracking-only RFID tags are passive and do not rely on a power source.
- D. Incorrect.
Encryption is generally not a primary concern for tracking-only RFID tags as they are designed for identification rather than secure data transmission.
- E. Correct.
The capability of the Cisco wireless system to handle and track a large number of RFID tags simultaneously is crucial for large-scale inventory tracking in a retail or distribution environment.
