Internet Satellite Providers like Viasat normally have a professional technician come out to your residence to mount a dish onto your house. This is because it needs to be mounted in a specific place so that it receives the best signal possible. The professional tries to find an open place on the roof or the side of your house without anything getting in front of the dish and possibly interfering with the signal. There is a signal that is sent out through your modem to the dish on your house. That signal from the dish is then shot out to a satellite in space, then transmitted back to the dish and back to the modem again. This is the communication process of the information that is sent. There can’t be anything in the way of the dish to cause a bad connection or slow the connection down so you can have the best service possible. You don’t have to do anything with the installation process so you can have the best experience with satellite internet as possible. If you would like, and if you have one, you can connect your own router to the modem that is supplied to you. When you get a contract with Viasat, they also give you a modem with a router inside of it. If you prefer the one you own more, then you can just connect the one your own to the modem or you can get the professional to do it.
