Glossary of satellite internet connection

When you look at an internet connection offer, you are sometimes faced with technical jargon. Difficult to understand, difficult to navigate between the words and other acronyms used by the operators … We have deciphered for you the 5 keywords to know to fully understand the subtleties of the satellite Internet connection.

Kb / s, Mb / s, Gb / s and yield

There are usually numbers in front of these abbreviations. 100 Mbps = 100 Megabits per second.

This is the speed of your internet connection, also known as performance.

With satellite Internet access, speeds can reach 100 Mbps. As with all Internet connections, this is the theoretical maximum speed at reception, that is, the maximum speed that can be achieved while uploading content from the Internet, to display a web page for example.

For purists, here is the official definition of Wikipedia: A megabit is a unit of measurement in computing. A megabit is worth a million bits, or 1000 kilobits. The 1000 megabit pool represents a gigabit. ”

Traffic

Satellite Internet is a shared resource among all its users. A few years ago, satellite resources were limited and subscribers had a share of internet data to exchange each month. This is called traffic.

Today, the Konnect satellite, on which Nordnet’s offerings are based, has a very large capacity and offers unmatched performance! No more data quotas – the connection is unlimited. However, some offers offer an advantage: priority traffic to overtake other users of the service when the satellite is requested (a bit like a priority lane of the highway at peak times).

Blank area

For several years now, digital deserts have been referred to as the “white zone”, by image: large rural areas without any mobile network and without an Internet connection.

Today, thanks to the deployment of Very High Speed ​​in France, these areas are scattered, here and there, throughout the territory. There, the fiber has not yet arrived and ADSL is often too slow.

Families, professionals and communities located there still have the opportunity to benefit from Very High Speed ​​access by choosing a standalone solution, independent of any wired network: satellite Internet access!

Ping / latency

The satellite is almost 36,000 km away: the time that the signal travels back and forth between your device application and the satellite is called latency (“ping”).

Therefore, it is logically higher than with a wired connection, and inevitable with satellite internet connections based on a geostationary satellite.

Banda Ka / Banda Ku

In space, the telecommunications satellite exchanges data with the Earth through a range of frequencies: more or less powerful beams to bring the Internet into the territory.

At the beginning of satellite Internet access, the frequency band used was Banda KU : a first technology to cover the entire French territory in Broadband, thanks to a wide coverage range.

Frequently, the frequency ranges evolved with the Banda KA: KA band bundles are more numerous and concentrated, which has significantly increased the connection speed and provided a better connection quality, always throughout France.

The principle is simple: a satellite in geostationary orbit sends a signal of wide coverage throughout the territory. Therefore, every user has access to the Internet, wherever they are in mainland France.

In 2011, the new KASAT satellite (dedicated to satellite Internet access) was launched. This smart satellite is revolutionizing broadband coverage by dividing the signal into coverage areas (called “beams”). Each bundle is managed independently and adapts resources according to the number of users.
