Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 88

Which two statements are characteristics of RF mathematics? (Choose two.)

Answer options

• A. For every gain of 3 db, multiply the transmit power mW by 2
• B. For every gain of 10 dB, multiply the transmit power mW by 100
• C. For every loss of 30 dB, multiply the transmit power mW by 1000
• D. For every loss of 30 dB, decrease the transmit power mW by 1000
• E. For every gain of 3 dB, divide the transmit power mW by 2

Correct answer: A, E

Explanation

Option A is correct because a gain of 3 dB represents a doubling of power. Option E is also correct as it states that a 3 dB gain corresponds to dividing the power by 2, which is a common principle in RF mathematics. The other options incorrectly describe the relationships between dB and power changes.
