The convenience of our utility systems; water, gas, electricity, cable and telephone, is usually taken for granted. But when any part of these services is disrupted, it can throw our lives into chaos. And our only question is "when will it be turned back on?" If the damage is on a large scale, the repair of these services will require intercommunication between agencies, on a variety of radio frequencies. In the case of disaster damage from tornadoes, hurricanes, and floods, utilities will need radio contact with law enforcement, fire and rescue, even the National Guard.
A reliable radio system and clear communication between these various departments and agencies is vital. It can mean the difference between life and death. Radio interoperability provides a resource for meeting this need. The grouping of radios of differing frequencies for the immediate transmission of orders, status, and calls for help aids in quickly bringing disaster relief.
