Which among the following statements is false about the outcome of increasing transmission power?

(a) Transmission range at higher frequencies is maintained

(b) Path loss is increased

(c) Interference is increased

(d) Transmission range at lower frequencies is maintained

I had been asked this question during an online interview.

My doubt stems from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio

Best answer
The correct answer is (b) Path loss is increased

Explanation: Path loss is proportional to the operating frequency. Hence, transmission range gradually reduces with an increase in frequency when the transmission power is not modified. If transmission power is increased, the path loss is decreased with an increase in the amount of interference.
