Question

What does LOS communication mean? Name the types of waves that are used for this communication. Give typical examples, with the help of suitable figures of communication systems that use space mode propagation.

Answer 1

We will first write the full form of LOS. Then, we will define this communication system. Then, we will write the name of the wave that is used in this sort of communication system. Finally, we will write the examples and draw a suitable figure for the communication systems that use space mode propagation.

Complete answer:
LOS communication means Line Of Sight communication. This system works when the transmitting and the receiving antenna are in the line of sight of each other or in other words, are at the same level without any obstacle in between. Space waves are used in this type of communication system. These waves are simply components of ground waves that more or less travel through space.

LOS communication is used in FM Radio, microwave, and satellite transmission.The figure of communication systems that use space mode propagation is as follows

Additional Information: Communication systems are used for communication purposes. Space communication technology is also used in televisions. This technology has an upper hand over any other type of communication technology as the maximum of the time is uninterrupted. This is because the space waves are unaffected by any obstacle between the transmitting and receiving antenna as the waves propagate through space.

Note: Students often mistake the diagram to be of LOS whereas in the question, it is asked for the diagram of something else. Students should read the question carefully and then start answering the question.
