The availability of highly reliable and secure communications systems is integral to the mission of Public Safety and Security teams (police, fire brigades, ambulances, etc.) engaged in critical situations. It is a true lifeline for the first responders on the ground and the public they serve.

Public Safety Mission-Critical are at a turning point: around the globe, they are progressively migrating from legacy professional mobile radio (PMR) technologies to LTE/5G solutions with MCX (Mission-Critical voice, data, video) to both support legacy and new advanced multimedia services and enhance situational awareness during crisis situations .

This evolution is driven by multiple factors: • The increasing number and magnitude of crises (climate-related events such as fires and floods, social demonstrations, riots, terrorist attacks) which stresses the resources and capabilities of Public Safety organizations • The correlated growing imperative for first responders and command centers to have more advanced communications systems leveraging data, video, and real-time geolocation in addition to voice to increase situational awareness and operational efficiency • The limitations of existing PMR solutions (TETRA, P25, etc.) in terms of service evolution and supplier concentration • The growing readiness and maturity of the 3GPP and MCX ecosystem for Mission-Critical communications in terms of suppliers (network, device, application), standards, and solutions.
