If you live or work out in the middle of nowhere then you’ll have few internet connection options. One of those options is dialup, and the second is usually satellite.
Satellite internet is a wireless connection that involves 3 satellite dishes; one at the internet service providers hub, one in space and one attached to your property. In addition to the satellite dish you also need a modem and cables running to and from the dish to your modem. Once you have everything connected, the ISP will send the internet signal to the dish in space which then relays it to you. Every time you make a request (new page, download, send an email, etc) it goes to the dish in space and then to the (ISP’s) hub. The completed request is then sent back through space, to your dish and then to your computer.
