Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 104

What is the EIRP value for a transmitter that has a transmitter capable of 15 dBm, an antenna that has a gain of 12 dBi, and a cable that connects the transmitter to the antenna that has 1 db loss?

Answer options

• A. 26 dBm
• B. 100 mW
• C. .86 dBm
• D. 165 dBm
• E. 1000 mW

Correct answer: A

Explanation

The Effective Isotropic Radiated Power (EIRP) is calculated by adding the transmitter power (15 dBm) and the antenna gain (12 dBi), then subtracting the cable loss (1 dB). This results in 15 + 12 - 1 = 26 dBm, which is why option A is correct. The other options do not accurately represent the EIRP calculation and are therefore incorrect.
