Narrowband Communication Systems

Digital narrowband mobile radio solutions (TETRA, DMR, GSM-R) for mission-critical and business-critical applications designed to guarantee operability even in case of significant infrastructure malfunctions, guaranteeing full delivery of voice and data services.

Professional Broadband

Systems that combine the versatility and capabilities of 4G and 5G networks with the operational models of traditional professional networks, extending their operability.

Hybrid Networks

Integrated multi-technology network solutions (narrowband/broadband) that guarantee full interoperability between the various radio carriers, supporting communications, including multimedia, between field operators and operations centres, and allowing a gradual and controlled evolution towards new generation networks.

PTT Communications over Cellular Networks

Cellular networks and related tools, such as smartphones, are becoming increasingly important in mission and business-critical communications. The radio communications paradigm is consequently being extended with multimedia through smartphones operated on public or private networks.
