Abstract
ATSC 3.0 IP-based data is broadcast in signed and encrypted messages to one or more ATSC 3.0 receivers that control a barrier such as a gate, usually closed to traffic, in the event of an emergency, such as a fire, to open the barrier to allow additional escape routes or to provide access for emergency vehicles. The ATSC 3.0 system supports a wake-up mechanism which allows a receiver to go to a power saving mode. Periodically the receiver wakes up to check for the wake-up bit. Receipt of an 'open' message actuates a battery powered or solar assisted system to open the gate while saving on power consumption. Present techniques can also be used to send messages such as Amber alerts to roads, freeways, and other public signage and to control remote water pumping and sewer pumping stations which currently depend on point-to-point UHF radio links.
