Q171.
Which among the following do not belong to the fixed transmitter, mobile receiver configuration?
Discuss
Answer: (c).Radio astronomy Explanation:Broadcasting primarily includes consumer communication applications such as AM, FM, etc. Radio positioning includes services such as GPS and radio navigation. The long-wave standard time signal produced by The National Institute of Standards and Technology (NIST) which continuously broadcasts time and frequency signals at 60 kHz is an example of standard time signal services.
Discuss
Answer: (a).Determining transmission parameters to avoid interference Explanation:The major policy challenge for the fixed transmitter, mobile receiver configuration is the determination of transmission parameter levels which do not cause interference and are economically feasible. For example, determining the number of stations required for broadcasting in a region.
Q173.
Which among the following would result in increased out-of-band rejection at receivers while broadcasting?
Discuss
Answer: (d).Close band spacing between stations Explanation:The close band spacing between stations is a potential method for increasing the station density. However it causes increased out-of-band rejection at the receivers. Reduction of transmission and increased frequency reuse are other approaches for increasing station density. However these methods result in reduced coverage.
Q174.
Which among the following is true about passive sensing configuration?
Discuss
Answer: (d).Operational area is unknown Explanation:Mobile transmitter, fixed receiver configuration includes active and passive meteorological and Earth exploration system. In passive sensing configuration, the operational area is unknown. In the active sensing configuration, the transmitter location is unknown.
Q175.
What device characteristic is necessary for the mobile transmitter, fixed receiver configuration?
Discuss
Answer: (b).Sensitive receiver Explanation:Mobile transmitter, fixed receiver configuration employs sensitive receivers. Sensitive receivers require the adjacent channel systems to have small out-of-band emission. This is achieved by using guard bands.
Discuss
Answer: (c).Fixed transmitter, fixed receiver Explanation: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.
Discuss
Answer: (b).Determination of the location of the fixed receiver Explanation:Radio astronomy studies the celestial phenomena by measuring the radio waves characteristics emitted by the physical processes occurring in space. The location of the fixed receiver is a policy challenge as the receiver has to be located at a spot with minimum interference from commercial systems.
Discuss
Answer: (b).Mobile transmitter, mobile receiver Explanation:Mobile transmitter, mobile receiver configuration includes a variety of mobile services. The private land mobile radio services allow governments, commercial organizations, and non-profit organizations to use mobile and fixed communication systems to guarantee safety, increase productivity and efficiency.
Q179.
Which among the following is necessary to ensure operation free of interference?
Discuss
Answer: (c).Minimum distance of operation Explanation:The mobile transmitter, mobile receiver configuration presents an environment with different power levels and unknown geometries between the receivers and transmitters. It is difficult to provide operation free of interference without fixing the minimum separation distance. In other words, all interference computations are performed assuming minimum separation distance.
Discuss
Answer: (a).Conflict between the required amount of frequency by the radio system and frequency used Explanation:The policy challenge of the mobile transmitter, fixed receiver configuration is that the frequency usage is extremely small but it demands a large amount of frequency. The operational frequencies also tend to be particular to the physical characteristics of the chemicals that are to be sensed.
