Motorola Solutions Inc. has been selected by the Brazilian Band Administration Entity $(EAF)$ to implement a new nationwide critical communication solution for Brazil's defense and security organizations. The project aims to integrate existing land mobile radio (LMR) networks with new mission-critical push-to-X $(MCX)$ broadband services, enhancing interoperability and data access across the agencies. Utilizing the government's private 4G network, Motorola will implement WAVE PTX and Critical Connect to facilitate communication among various organizations, including the army and police forces. This initiative is expected to improve real-time coordination during joint operations, ultimately contributing to better-informed decision-making and increased public safety. The solution will initially be rolled out in Brasília, enabling seamless information sharing and coordination across different security agencies.
