Question

Under good propagation conditions, increasing the transmission energy is a poor technique to increase spectrum efficiency.

(a) True

(b) False

The question was posed to me in exam.

I want to ask this question from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct choice is (a) True

For explanation: Effective spectrum usage considers both the amount of spectrum used and the area of propagation.  Under good propagation conditions, increasing the transmission energy is a poor technique to increase spectrum efficiency. By increasing the efficiency of a single radio, the spectrum cannot provide proper communication conditions for other users of the spectrum.
