Mission Critical Communications

The First Responder Network Authority was established to deploy a nationwide broadband network for public safety communications and meet first responders’ communications needs. One of the key capabilities that public safety requested during the planning phase of FirstNet was the ability to determine the Z-axis, or vertical axis, location of personnel. FirstNet’s Z-axis capability is the next evolution of FirstNet Enhanced Location Services, designed to assist with identifying where a first responder is located within a building.
