The service area of space wave communication increases by

A

increasing the height of transmitting antenna

B

decreasing the height of receiving antenna

C

increasing the height of both transmitting and receiving antenna

D

decreasing the distance between transmitting and receiving antenna

Text Solution

Verified by Experts

The correct Answer is:
C
Maximum range of space wave propagation ` d = (4)/(3) xx 1.23 [ sqrt(H_t) + sqrt(H_r)] implies d prop H_t`
` d prop H_r `
`:.` d increases if `H_t and H_r` i.e. height of transmitting and receiving antenna increases.

Communication Services

Perhaps, the most commonly used mode of communication involves use of free space as a communication channel between transmitter and receiver. The various possible modes of using of free space have been described below Ground wave communication : This mode is used for low frequency as at high frequency, losses become large. This is useful for distance of the order of 1 km. Space wave communication: The signals are transmitted directly from transmitter to receiver. There is no limit to upper frequency, but its range is limited to few hundred kilometers. The range depends on the height of transmitting antenna Sky wave communication : The signals are sent towards sky They are reflected back towards earth by ionosphere. Its range can be above 500 km. But, very high frequencies (above 10 MHz) are not reflected back. Satellite communication: The signals that cannot be reflected back by ionosphere are reflected back by satellite. Moon is a passive satellite of earth. The cordless phone installed in a house uses
