1.	What is a radio environment map?(a) Radio environment map represents a collection of access points in the immediate vicinity(b) Radio environment map provides insight on radio environment over multiple domains such as regulation and frequency emission(c) Radio environment map represents cognitive radios in the immediate vicinity(d) Radio environment map represents cognitive radios participating in cooperative sensingThis question was posed to me in a national level competition.My question is based upon Next Generation Wireless Network in chapter Next Generation Wireless Network of Cognitive Radio
Answer» The correct option is (b) Radio environment MAP provides insight on radio environment over multiple domains such as regulation and frequency emission The best explanation: Radio environment map provides an abstraction of real time radio environment. It defines the radio environment of cognitive radio USING multiple characteristic features such as geographical conditions, regulation, policy, CAPABILITY of radio equipment, and radiofrequency EMISSIONS.
