Modern Telegrams from Across the World

People use a variety of different technologies and infrastructures to access the Internet, including dial-up lines, ADSL, mobile, and satellite internet (Internet über Satellitenschüssel) access. There are advantages and disadvantages to each of these methods, with differences in speed, bandwidth, and latency. While most people use some kind of terrestrial based Internet technology to go online in the 21st century, satellite access still plays a big role for many people around the world. There is a large variation in different types of satellite systems available, including two way systems and one way systems. In comparison to terrestrial communication, satellite Internet services do have some limitations related to latency and weather, however, they are often the best alternative for people living in remote locations.

Satellite Internet access is used to describe any kind of Internet access where satellites are used. There are a number of low Earth orbit satellites situated around the planet, providing Internet access to people in hundreds of different countries. While these geostationary satellites are able to provide high speed data transmission, they do have some limitations when compared to standard terrestrial services. For example, they can not reach the polar regions of the Earth, they are affected by high latency, and they are adversely affected by rain and other weather conditions. In particular, because a geostationary orbit is directly above the Earth’s equator, it is unable to provide true low latency communication. This delay is the biggest drawback with satellite communication, and the main reason why it is not used very often by people who can access terrestrial services.

However, satellite Internet technology does play an important role in Internet delivery, especially for people who do not have access to standard ADSL and mobile microwave services. For geostationary satellites, the problem of latency can be mitigated through the use of TCP acceleration, which splits up the feedback loop between the sender and receiver. While two way satellite communication is used by many people, there are also a number of one way satellite systems, with terrestrial transmit or one way multicast capabilities. This allows satellite Internet customers to obtain high speed downloads from satellites while still using standard dial up modems for upstream data. While satellite Internet access does have some limitations when compared to terrestrial services, the ability to access the Internet in remote locations makes up for these shortcomings.
