Currently, most Internet trunk and local networks are wired terrestrial networks—for example, fiber optics, cable, and phone lines—with wireless access.
In that sense, for the last few years researchers have been working on the next generation of the Internet, so that it can support high-bandwidth applications and ubiquitous computing with mobile/wireless networks, amongst which satellite networks offer a great potential for multimedia applications, thanks to their capacity to transmit and multicast large amounts of data over a very large area and achieve global connectivity.
It is a data communications network facilitated by one or more communication satellites on Earth’s orbit. It can be divided into two segments: space and ground.
As we can see, a satellite network is a very complex data communications network and implies a significant initial investment and administration cost.
Based on the type of satellites and their orbital positions, satellite networks can be classified based on GEO, LEO, MEO or hybrid.
Since neither LEO nor MEO satellites can remain in a fixed position, relative to the Earth’s surface, a satellite network based on any of these orbits often requires a constellation of multiple satellites to provide uninterrupted service. These satellites are in constant motion, so when one moves out of range, its communication will be covered by another satellite that is within range.
A satellite teleport is the ground structure of the global satellite network. Its function is to provide terrestrial networks with access to the transponders of satellite antennas in orbit, located at 36,200 kilometers above the equator. They are located in strategic locations around the world, allowing them to communicate with satellites by line of sight.
In this sense, the difference between teleports and other Internet and telecommunications service providers lies precisely in the access to these satellite antennas, which allows a greater reach of mobile technologies, wireless networks, microwaves and fiber optics.
In a satellite teleport, the large parabolic antennas that point up to the sky from a fixed position stand out, since the satellites with which they communicate are in geostationary orbit; this means that the satellite is always located at the same position in the sky. In addition to satellite dishes, the satellite teleport also hosts network equipment and fiber optic links, connecting the location to data centers.
For example, during a Wi-Fi session, the distance traveled by data is immense. Taking into account that the geostationary orbit is 35,786 kilometers or at 22,236 miles away, when a website request is loaded into the browser, it has traveled more than 50,000 miles or the equivalent of circling the Earth twice. The most amazing thing is that it does this entire route is done in about 1.5 seconds!
Following this line, a satellite link is a channel through which data is sent and/or received, which travels through radio frequency signals that are broadcasted from a main ground station (satellite teleport) to a satellite; this, in turn, forwards the signals to a remote ground station located anywhere on Earth, where they are converted into data to access: internet, telephony, video and streaming. This is accomplished by means of a satellite modem.
