Question

What is the concept for accommodating a large number of users in a limited radio spectrum?

(a) Grade of service

(b) Trunking

(c) Multiplexing

(d) Multitasking

This question was addressed to me in an online interview.

Query is from Trunking and Grade of Service in section The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Right option is (b) Trunking

The best I can explain: Cellular radio systems rely on trunking to accommodate a large number of users in a limited radio spectrum. The concept of trunking allows a large number of users to share the relatively small number of channels in a cell by providing access to each user, on demand.
