What is broadband?
Put simply, the term "broadband" refers to a high-speed connection to the Internet. But the answer to the question doesn't stay simple.
First, there are a number of technologies that can provide this connection. The main ones are DSL over copper phone lines, cable service over coaxial cable, fiber optic cable and wireless signals coming from fixed towers or from satellites. Each of these has its own characteristics involving price, area of coverage and technology constraints.
And second, the definition of what is high-speed is changing regularly. Late in 2010, for example, the Federal Communications Commission officially raised the speed that it considers broadband, overnight expanding the geographic areas that are considered unserved. Dial-up service, still some people's choice, is not considered broadband service.
