Question

Which among the following is not used as an attribute for classifying spectrum sharing?

(a) Architecture

(b) Spectrum allocation behaviour

(c) Spectrum access technique

(d) Spectrum sensing behaviour

I got this question during an interview.

Question is from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is:

(d) Spectrum sensing behaviour

Explanation:

In the context of spectrum sharing within cognitive radio networks, the classification of spectrum sharing typically involves the following attributes:

• Architecture (option a) refers to the structural design of the system, such as centralized or decentralized architectures in spectrum management.
• Spectrum allocation behaviour (option b) pertains to how the spectrum is allocated, either by a central authority or through decentralized mechanisms.
• Spectrum access technique (option c) describes the methods used to access the spectrum, such as dynamic spectrum access (DSA), opportunistic spectrum access, or licensed/ unlicensed access.
