1.	Which among the following configurations include radio astronomy services?(a) Fixed transmitter, mobile receiver(b) Mobile transmitter, mobile receiver(c) Fixed transmitter, fixed receiver(d) Mobile transmitter, fixed receiverI have been asked this question during an interview for a job.I'd like to ask this question from Next Generation Wireless Network in division Next Generation Wireless Network of Cognitive Radio
Answer» Correct answer is (C) Fixed TRANSMITTER, fixed receiver The best I can explain: Fixed transmitter, fixed receiver configuration includes point-to-point, point-to-multipoint, and radio astronomy services. Both endpoints are in fixed LOCATIONS. The communication path may be one way between the transmitter and receiver or it may be TWO way between two TRANSCEIVERS.
