Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 111

An access point is currently transmitting at 4 mW. The customer needs to increase its signal strength by 6 dB to create a larger wireless cell. What should the new transmit power be?

Answer options

• A. 8 mW
• B. 10 mW
• C. 12 mW
• D. 16 mW
• E. 24 mW

Correct answer: D

Explanation

To increase the signal strength by 6 dB, the power must be doubled. Starting from 4 mW, doubling it results in 8 mW for the first 3 dB increase, and doubling again gives 16 mW for the full 6 dB increase. Therefore, the correct answer is D, while the other options do not provide the necessary increase in power.
