Telecommunications & Network Engineering
►
We engineer private telecommunications networks.
• Why do we need a private communications network?
• What information goes on the network and where does it go?

Private Communications Network
►
UTC Research Report: “Hurricanes of 2005: Performance of Gulf
Coast Critical Infrastructure Communications Networks”
– “In sharp contrast to commercial telecommunications networks,
the private internal networks (radio, microwave, and fiber) of
electric utilities for the most part continued to function throughout
and immediately after the storms.”
– “Success was due to built-in redundancies and recovery
mechanisms that would be cost-prohibitive for a for-profit network
designed to serve the general public.”
