As the name implies, cable modem services would be provided through local cable companies. ISDN is the acronym for Integrated Services Digital Network. ISDN is a type of digital phone line provided by the phone company with limited availability in our area. It works on similar principles, but as the name implies, satellite internet service gives you access by receiving transmissions from satellites that are many miles up above Earth. Wireless internet service receives transmissions from land-based antennas which are usually within a few miles of your location.
Satellite transmissions suffer from latency, because the signal has to travel such long distances.
Wireless equipment can be as fast as 11Mbit, but typical connection rates are in the neighborhood of 1Mbit. This is roughly 20 times faster than a good 56k modem connection. MB means megabyte while Mbit means megabit. There are eight bits in a byte. In the computer industry, capacity is usually stated as megabytes while transfer rate is usually stated as megabits.
