What type of network complements the Sirius satellite signals?

The choice of a repeater network as the correct answer is based on the function of repeaters in enhancing signal coverage and reliability for satellite communications like those provided by Sirius. Satellite signals can sometimes have limitations in certain areas due to geographical obstructions or environmental factors. A repeater network acts as an intermediary that receives the satellite signal and retransmits it, helping to ensure that the signal reaches areas that may otherwise experience weak or no connectivity.

In the context of Sirius satellite signals, having a repeater network allows for extended reach and improved quality of service. This is particularly important in urban areas or locations surrounded by tall buildings or natural barriers, where the direct path from the satellite to the receiver may be obstructed.

This also indicates that while other options like local broadcast networks or satellite internet networks may serve different purposes in communications, they do not directly complement the functionality and reach of satellite signals in the same manner that a repeater network does. Similarly, relying on public internet access does not enhance the satellite signal; rather, it represents a different method of data transmission altogether.
