What is satellite Internet

Satellite Internet is a type of Internet service that transmits data from your provider to a satellite in space and then to a satellite dish in your home. This technology is particularly useful for rural users who do not have cable Internet services.

How Does Satellite Internet Work

Satellite Internet is the ability to transmit and receive data from a relatively small parabolic antenna on Earth and to communicate with a geostationary satellite in orbit 22,300 miles above the Earth’s equator. The orbiting satellite transmits its information to a location on Earth called the Network Operations Center (NOC). Since the NOC is connected to the Internet (or a private network), all communications between a satellite dish and the orbiting satellite will pass through the NOC before reaching the Internet.

Five important part which work in Satellite internet system

  1. Internet-ready device

    A device prepared for the Internet is any device that can access the Internet through the appropriate service. This includes your computer, tablet, smartphone, smart TV, game consoles and other Internet equipment. When you use the Internet on one of these devices, you send and receive data through your modem/router.

  2. Modem

    Convert data: a modem converts data to be transferred between your Internet-enabled device and the satellite dish. You can connect some devices, such as a computer, a connected TV or a game console, directly to your modem via an Ethernet cable.
    Wi-Fi features: However, these cables can become a bit foggy and you will still need Wi-Fi features for devices such as tablets and smartphones. This is where a router comes in. It connects to the modem to provide Wi-Fi functionality.
    Update your computer: some modems come with a built-in router. These take up less space, but it may be easier to upgrade your equipment if you purchase a separate modem and router.
    Most providers will offer to rent a modem/router, or you can buy the equipment yourself. If you decide to buy yours, make sure it is compatible with your ISP.

  3. Satellite in space

    About 22,000 miles above the surface of the Earth, the spacecraft used for satellite Internet maintains its position on the equator. They rotate with the planet so that the relay of the signal remains coherent. This allows bidirectional data communication between your satellite dish and the provider center or CNO.
    HughesNet and Viasat have their own point-beam satellite. Point beams cover specific areas of the United States, instead of using a beam to cover the entire country. With the benchmarks, you can access your individual content on the Internet instead of receiving the same as everyone else.

  4. Satellite dish

    The next step in the relay is your satellite dish. This dish must be placed precisely to be able to send signals in orbit to the provider’s satellite and receive information. A certified technician from your provider will handle the placement for you.
    The delicate positioning of a satellite dish can hinder the mobility of satellite Internet for leisure vehicles. In addition, your account is configured to be under a specific spot beam of the satellite in space. Therefore, the distance you can travel while you have access to the Internet would be somewhat limited.

  5. Network Operations Center (NOC)

    NOC stands for Network Operations Center, When you request for information on the Internet or click on a link, transmit a live broadcast or open Facebook, the data for that request is downloaded through the previous relay. The satellite then transmits this request to the NOC.
    By using a satellite dish much larger than the one you have at home, the NOC receives your request. Then, the CNO connects to the Internet, collects the information it has requested and sends it through the relay.
    All this process, including the transmission of 22,000 miles of information in the round trip space twice, is done in fractions of a second.
    Since the information has to travel so far, you may notice a higher latency (also called delay) than with ADSL or wired Internet, but advances in technology have made satellite Internet much faster than before.
