For Internet access via satellite, a small satellite dish is installed outside the home or office.
Satellite Internet services usually provide downstream data rates of about 500 kbps and 128 kbps upstream.
One problem with the service is propagation delay, due to distance the signal must travel, resulting in relatively slow response times.
For example, a to get a response from a Web server, a signal must travel from the user’s site to the satellite, then down to the ISP and back, or about 90,000 miles, ½ second at the speed of light
