Communications sector

Overview
The communications sector is a diverse, competitive, and interconnected industry using terrestrial, satellite, and wireless transmission systems. The transmission of these services has become interconnected; satellite, wireless, and wireline providers depend on each other to carry and terminate their traffic and companies routinely share facilities and technology to ensure interoperability.

The communications sector is an integral component of the U.S. economy as it underlies the operations of all businesses, public safety organizations, and government.
