Question

Which among the following relies on efficient allocation of spectrum?

(a) Effective multiplexing

(b) Effective modulation

(c) Capacity of open spectrum access

(d) Diversity

I got this question in an online quiz.

This interesting question is from The xG Network Architecture topic in chapter Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is (c) Capacity of open spectrum access

Easiest explanation: Factors such as the capacity of open spectrum access and quality of service rely on the ability of a radio to efficiently allocate radio spectrum. xG network architecture aims for effective use of unlicensed spectrum band which have multiple heterogeneous networks.
