The communications sector is a diverse, competitive, and interconnected industry using terrestrial, satellite, and wireless transmission systems. 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. The transmission of these services has become very 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 and efficiency.
The private sector, as owners and operators of the majority of communications infrastructure, is the primary entity responsible for protecting Sector infrastructure and assets. Working with the Federal Government, the private sector is able to predict, anticipate, and respond to Sector outages and understand how they might affect the ability of the national leadership to communicate during times of crisis, impact the operations of other Sectors, and affect response and recovery efforts.
The Communications Sector is closely linked to a number of other Sectors, including Energy, Information Technology, Financial Services, Emergency Services, and Postal and Shipping.
