The Net is a terrestrial-based apparatus, and satellite Internet technology uses an extraterrestrial-based apparatus, I.e. satellite, to get connected to the Internet backbone. The need for the accessibility through satellite is the lack of DSL and cable lines in remote places and in mobile situations such as seafaring boats.

Theoretically, Adsl Via De Satelliet services are available worldwide. With tooway internet services, you need to have the capacity to enjoy high speed Internet connections no matter you're in the boats in the middle of south pacific or the jungle of Amazons.

At the time of writing, satelliet internet speeds range from 700kbps to 1.5mbps for an affordable package. Both upload and download speed for satellite Internet service is considerably slower when it is comparing to cable or DSL connection. But when compare to regular dial up modem, satellite Internet connections are more or less 10 times quicker!

Usually, satellite Internet can be divided into three groups: One-way Multicast, Oneway with Terrestrial Return, and Twoway satellite access. The key differences of these solutions are the equipments set up as well as the core connection strategy.

In general, One-way multicast Internet Via De Satelliet systems are employed for IP multicast-based data, audio and video distribution; while for One-way terrestrial return satellite Web apparatus, connection are done with conventional dial-up access to the Net, with outbound data traveling through a phone modem, but downloads are sent via satellite at a speed near that of broadband Internet access. In terms of two way satellite Web service, date is sent from remote sites via satellite to a hub, which then sends the info to the Net. The satellite dish at each location should be precisely placed to prevent interference with other satellites. The oscillators in some radar detectors can cause interference with these systems.

As technology advanced, secure satellite Internet connections are now available in a very low price to the people. As in Usa, Hughes Net is among the top companies that offer Internet services via satellite. They offer four service bundles that each offers their own unique group of characteristics and connection speed parameters.

At the user's area, the access is set by the level of service needed, whether it is one way or twoway satellite service. Oneway service may require a regular dial up service. A user may need to really have a minimum of Windows- or Mac-supported PC with a networking capacity. Other requirements include Ethernet port. Other than hardware requirements, applications programming to manage interfaces is needed.

Broadband access through satellite is a costly option to cable modems and DSL. The access is limited by the expensive installations and also the current weather conditions. Besides, the uplink speed is limited by the dialup speed just like dial-up Internet. The long-haul space between the dish and satellite results in delay of the access read more.
