The Technology Behind Satellite Communication Networks — YubiGeek

Satellite communication networks are a technology that arouses the enthusiasm of many consumers. They are a revolution in the communication system, thanks to the fluidity they bring and their wide coverage. Taking the example of the Internet, ADSL and fiber have shown their limits in terms of coverage, where satellite communication performs. What explains the performance of the technology behind satellite communication networks.

Satellite communication networks are a solution that aims to optimize the quality of communication between users. They provide reception and transmission of digital signals by satellite. This technology is generally based on the use of geostationary satellites, located at a very high altitude. With these networks, communication is established from a terrestrial communication system, most often a terrestrial dish. Being able to connect to a satellite, the latter emits electromagnetic waves and signals. It also has an antenna associated with a modem, so that it can convert digital data into an analog signal and vice versa.

In the specific case of a geostationary satellite, it is often a small dish, oriented precisely towards the satellite to transmit and receive communication data. The signals emitted between the dish and the space base that is the geostationary satellite are transmitted using a band frequency. According to the page, there is different frequency bands, which are allocated by the International Telecommunication Union, depending on the destination. The reception and transmission of signals by the geostationary satellite are ensured by transponders which, as you will have understood, integrate a transmitter/receiver pair.

The advantages of using satellite communication networks

The enthusiasm of individuals and companies for satellite communication networks can be explained by many reasons. Geostationary satellites have the advantage of transmitting signals through the broadcast system, which covers a considerable land area. In the past, satellite networks were more limited to digital and analog communications. Today, they have evolved and offer mobile phone and broadband internet services.

Taking the example of the Internet, these networks manage to reach areas that ADSL and fiber cannot reach for the time being. In the mountains, on the high seas or in isolated areas, networks linked to geostationary satellites guarantee you the availability of internet. Better still, you benefit from a high speed in the transmission of data, with the key to a considerably reduced latency time. For companies, and even for individuals, this is a significant asset.

In addition to their security and reliability, satellite communication networks avoid interference. They optimize the operational capacity of companies, thanks to various facilities such as instant messaging, the use of specific data and applications, etc. We must also emphasize the availability at all times of satellite communication networks, in addition to global coverage for broadband. In addition to these advantages of geostationary satellite communication networkswe can cite :

  • the diversity of frequency bands: L, Ku, C, X, Q/V, Ka,
  • the ability to use Push-To-Talk (PTT) tools,
  • the independence and autonomy of satellite communication networks with respect to terrestrial conditions,
  • accessibility of equipment in terms of price.

The ease of installation of this technology makes it an even more advantageous solution.

The future of satellite communication networks

Satellite networks should see their potential increase tenfold in the years to come. Taking the example of geostationary satellites, the time when they suffered strong criticism is now over. Witness the VHTS geostationary satellites (Very High Throughput Satellite System) which impress with their capacities of up to 55 Gb/s. Such satellites, which by the way incorporate industrial models, are synonymous with very high-speed connectivity for millions of users. Faced with the growth of the market, renowned players in satellite communication such as Eutelsat are preparing for fierce competition.

This is proof that the satellite network market has enormous growth potential. If the European Union agrees to significant funding for thesatellite broadband access, this proves that the European institution sees in this technology the future of communication. In addition, many satellite connection projects have been finalized in Europe, precisely to strengthen the options offered by this technology. One thinks in particular of the BRESAT and SABER projects, which are only the first of a lot in this direction.
