In satellite communication, a communication satellite functions as a repeater between which of the following?

Difficulty: Easy

Correct Answer: Many transmitting stations and many receiving stations

Explanation:


Introduction / Context:
A communication satellite is essentially a repeater located in space, receiving signals from Earth stations and retransmitting them back over a wide area. This enables global connectivity and broadcasting.


Given Data / Assumptions:

  • Satellites operate with transponders (receivers + transmitters).
  • They receive uplink signals and retransmit on downlink frequencies.
  • Service multiple geographically dispersed users simultaneously.


Concept / Approach:
Satellites act as bent-pipe repeaters, enabling many-to-many communication. One satellite can handle numerous uplinks and distribute them to many receivers, depending on its transponder capacity.


Step-by-Step Solution:

Earth station A uplinks signal.Satellite transponder shifts frequency and amplifies.Downlink distributed to multiple receiving stations worldwide.


Verification / Alternative check:

Broadcast TV via satellites confirms many-to-many role.


Why Other Options Are Wrong:

Single transmitter-receiver link ignores satellite's multipoint capability.One-to-many applies to broadcasting only, not general communication.None of these: invalid since satellites clearly act as repeaters.


Common Pitfalls:

Thinking satellites only support one-to-one links, ignoring multiplexing and transponders.


Final Answer:

Many transmitting stations and many receiving stations
