Internet access terminology can be very confusing, especially if you’re trying to choose a new ISP. Each technology has its differences and some may be better at certain tasks than others, consequently it is important for consumers to understand the advantages and disadvantages of each prior to choosing a provider. This page seeks to explain the methods using simple language and is best used in conjunction with our 'Jargon Buster' section.

Satellites are effectively small autonomous space stations that can be placed in orbit around our planet and used as specialised wireless transceivers (receiver/transmitters) to relay information between different points on the ground. Their high altitude above the Earth gives them excellent coverage, which is especially useful in remote areas.

Performance is known to be quite variable and satellite is no good for multiplayer gaming due to the time it takes for signals to go from the Earth to the satellite and back again (high latency). Satellite Internet access is often both costly or confusing to consumers and typically works in one of two different ways:

• One-Way::
  This cheaper option sees the satellite ONLY handling downstream (download) data by allowing you to dial in via a normal land based ISP (e.g. dialup) to handle the upstream (upload) requests for data.
• Two-Way::
  With the more expensive two-way option the satellite handles everything; there's no need for an additional Internet connection.

The first generation of broadband capable satellites were slow and expensive analogue systems, while the latest digital satellites are well designed for delivering Europe wide Internet access. These offer performance closer to ADSL and Cable speeds, though their hardware (£200 to £1000+) and service rental costs (£30 to £200 per month) often remain prohibitively high.
