Question

What are the types of structures used to develop xG networks?

(a) Infrastructure and ad hoc networks

(b) Only infrastructure network

(c) Only ad hoc networks

(d) Centralised and distributed infrastructure network

I got this question in a national level competition.

My question is taken from The xG Network Architecture in division Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is (a) Infrastructure and ad hoc networks

The best I can explain: xG networks are made up of both infrastructure networks as well as ad hoc networks. xG users exist in a mixed spectrum environment and possess additional features to transmit on the licensed band. The path between the sender and the receiver depends on the type of network.
