Cable Vs. Satellite Network Communications
Since the 1990s, network communication has become an essential part of the way people do business, share entertainment, gather information and keep in touch. While network technology continues to advance, two of the primary forms that networks take are cable and satellite systems. These very different technologies share much in common while providing distinct advantages for some users.

Technology
-
Cable networks rely on relatively old technology, using coaxial cables to carry a signal from a regional or local routing point to users homes or businesses. Cable networks include cable television and cable-based high-speed Internet service. For a cable network to function, there must be a direct, physical link between the source of data and the end user.
Satellite networks use a series of satellites in orbit around the Earth to receive data and retransmit it, allowing for long-range wireless communication. Satellite networks include satellite television, satellite phones, satellite Internet service and even the Global Positioning System (GPS).
Similarities
-
Both cable and satellite networks serve the same general purpose of transmitting data between two points. Both rely on wires, since even in a satellite system there is a direct link between the user's satellite dish and a personal computer, television or wireless router. Cable networks use wires more extensively, but can also feature wireless segments such as a home network. Both technologies also facilitate two-way communication.
-
Coverage
-
One of the key differences between cable and satellite network communication is the area of coverage. Cable networks are only available where a service provider chooses to install cables and offer service. This includes most populated places, but neglects more remote areas. Satellite networks can reach any location on Earth with the same degree of fidelity, providing access to residents or visitors in the most remote areas.
Quality
-
Another important difference between cable and satellite networks is the degree of reliability and quality. Cable networks are not subject to signal interference, whereas satellite communication may become distorted during bad weather. Cable networks are also easier to repair, while satellites may be very costly to repair and cause service disruptions unless the service provider can switch the network to another satellite or institute a repair remotely.
Commercial Availability
-
Many different telecommunications companies around the world offer cable or satellite networks, or a combination of the two. Satellite and cable TV packages compete in many major American markets, giving viewers more programming choices and driving prices down due to competition. Satellite Internet is also widely available, though it is notably slower than residential cable Internet service at a similar price point.
