I'd like to ask this question from The xG Network Architecture in division Next Generation Wireless Network of Cognitive Radio

Answer 1

Right answer is (b) Intelligent spectrum access network

Easiest explanation: The xG network is also known as the secondary network, unlicensed network, cognitive radio network and dynamic spectrum access network. The xG does not have an exclusive right to use any spectrum band. xG networks aim to make use of temporarily unused spectrum bands.
