Designing Cisco Wireless Enterprise Networks (WIDESIGN, legacy) — Question 14

An engineer is assigned to replace an older data-grade autonomous wireless network with a Cisco controller-based wireless network to meet Voice over WLAN needs. The customer also wants all existing cable infrastructure to be reused and no new cable be specified. How should the engineer respond to the customers requirements?

Answer options

• A. Implement the wireless network with the restraints and decrease the TPC neighbor threshold to increase Tx power to provide overlapping cell coverage at sufficient SNR to provide for Voice over WLAN service.
• B. Implement the wireless network with the restraints and utilize high-gain antenna to provide overlapping cell coverage at sufficient SNR to provide for Voice over WLAN service.
• C. Inform the customer that the network will not likely function as desired and a post install survey with the possibility of some new cable would be recommended.
• D. Inform the customer that it is not possible to provide coverage and quality for Voice over WLAN using existing AP locations and an entire overbuild will be

Correct answer: B

Explanation

Option B is correct because using high-gain antennas can help achieve the necessary overlapping cell coverage and signal-to-noise ratio (SNR) for Voice over WLAN while adhering to the customer's requirement of reusing existing cabling. Options A, C, and D suggest either altering power settings or imply that the project cannot meet the requirements, which does not align with the goal of utilizing the current infrastructure effectively.
