Question

Which of the following has range extension capability?

(a) Sectoring

(b) Repeaters

(c) Scattering

(d) Micro cell zone concept

I have been asked this question by my school teacher while I was bunking the class.

This interesting question is from Improving Coverage and Capacity in Cellular Systems in portion The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Correct choice is (b) Repeaters

To explain I would say: Wireless operator needs to provide dedicated coverage for hard-to-reach areas, such as within buildings, or in valleys or tunnels. Radio transmitters used to provide such range extension capabilities are called as repeaters. They are bidirectional in nature.
