Question

Which among the following functions prevent collision?

(a) Spectrum analysis

(b) Spectrum decision

(c) Spectrum mobility

(d) Spectrum sharing

This question was addressed to me in quiz.

My question comes from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct option is (d) Spectrum sharing

The best I can explain: In the unlicensed portion of the spectrum, cognitive radio users have equal access to the spectrum and attempt to access the spectrum simultaneously. Spectrum sharing coordinates the network access such that collision is avoided in overlapping portions of the spectrum.
