SSB is particularly useful in which scenario?

Single Sideband (SSB) modulation is especially advantageous for special voice communications between shore stations and ships. This is primarily because SSB technology has a much narrower bandwidth compared to other modulation methods, which allows for more efficient use of the radio spectrum. By utilizing a lower amount of power to transmit signals, SSB can cover greater distances, making it ideal for marine communications where shore-to-ship contact is crucial.

In maritime environments, where clarity and reliable communication are critical, SSB also helps reduce interference and ensures better sound quality over long distances. Furthermore, the long-range capability of SSB makes it a preferred choice for vessels operating far from land, where other communication systems might not be available or affordable.

In contrasting scenarios, local broadcasting typically relies on amplitude modulation (AM), which is less efficient for long-range communications compared to SSB. Long-range data transmission usually depends on different technologies like satellite or specialized data networks rather than just voice communication methods. Lastly, while SSB can be utilized in satellite communications, it is not specifically tailored for this application, which often involves different modulation techniques optimized for data transmission to and from satellites.
