1.	Which among the following statements is false about the radio environment map?(a) Radio environment map does not require complex circuitry in the user device(b) Radio environment map records radio frequency emissions(c) Radio environment map is a spatiotemporal database(d) Available resource map is extended from a radio environment mapThis question was posed to me during a job interview.Question is from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio
Answer» Right option is (d) Available RESOURCE map is extended from a radio environment map The best I can explain: Radio environment map is a spatiotemporal database capable of supporting cognitive functionalities such as planning, learning, and reasoning of the USER equipment. The radio environment map is an extension of the available resource map which includes all radio activities in the UNLICENSED wide AREA network in real time.
