In layman's terms, you have information coming into the house from a service provider. A server or gateway holds the information until it is accessed by one or more devices. Here are examples of the limitless capabilities. Shared computer functions such as Internet connections, printers, or data will be available. You can even have touch-screen terminals that share information from multiple locations in the house.
Telephones can call between rooms and even answer a doorbell.
In the future, you will be able to assign a separate number for each family member. The ability to download and file favorite movies, games, and songs is not too far off. The integration of security and home automation will be possible. You can access your network and turn on an alarm or sprinkler system from a remote location. Although this sounds complicated, BellSouth and other providers are working to offer some of the first features in 12 to 18 months.
