What is a key benefit of using satellites in network communication?

Using satellites in network communication provides a significant benefit by enabling safe communication with unmanaged devices. Satellites extend coverage to remote and underserved areas where traditional wired or even some wireless communication methods may not reach. This capability is especially important for industries like agriculture, transportation, and disaster recovery, where devices may operate outside of a controlled network environment.

Unmanaged devices, which often include IoT (Internet of Things) devices, can be located in various environments, ranging from vehicles to remote monitoring stations. The use of satellites allows these devices to communicate securely, often utilizing encrypted channels, regardless of their location. This infrastructure supports data transmission in environments where security and reliability are critical, ensuring that information can be transmitted safely without reliance on land-based systems.

The other options address concepts that are either less relevant or not directly tied to the primary advantages provided by satellite communications. For instance, while bandwidth is important, the primary function of satellites is to provide connectivity, especially in challenging environments. Similarly, data processing speed may vary and is not a defining attribute of satellite communication, nor is the reduction of encryption a safety feature in satellite communication.
