In a world where public safety increasingly depends on reliable and flexible communication, the importance of modern, mission-critical infrastructures is growing rapidly. Police, fire, rescue, and civil protection organizations are under mounting pressure to respond effectively in complex emergency situations. Traditional radio technology alone is no longer sufficient. Forward-looking solutions combine proven systems with the possibilities of new broadband technologies.

One company consistently building this bridge is HMF Smart Solutions GmbH. Based in Bad Münder, Germany, HMF has been developing customized communication solutions for safety-critical applications for over 40 years. With projects across Europe and beyond, HMF is a trusted provider of Professional Mobile Radio (PMR), particularly based on TETRA, as well as innovative LTE/5G Mission Critical Services (MCX).

Convergent communication: TETRA meets MCX

At the heart of HMF’s current portfolio is a convergent communication solution that unites the strengths of two worlds: the mature, highly reliable TETRA technology for mission-critical voice communication, and the capabilities of LTE/5G for broadband data and video services. This hybrid concept allows emergency organizations to design their communications flexibly, depending on their needs:

• TETRA remains the first choice for robust group communication, high availability, secure voice channels, and direct radio connections even without network coverage (DMO).
• MCX services, in line with the 3GPP standard, complement this foundation with video streaming, data transmission, geo-information, and multimedia applications in real time.

The result is a platform that enables seamless interoperability between radio devices and modern broadband end devices such as smartphones, tablets, or bodycams. This allows fire departments, police, and rescue services to exchange information not only faster, but also more comprehensively—a decisive advantage in critical situations where every second counts.

ACCESSNET®-T IP: Scalable TETRA infrastructure

A key component of HMF’s portfolio is the ACCESSNET®-T IP TETRA infrastructure, one of the most flexible and scalable platforms on the market. It is suitable for both small local networks and nationwide radio infrastructures. Authorities and organizations can tailor the network architecture precisely and expand it step by step—without interrupting operations.

Key features of ACCESSNET®-T IP include:

• High scalability — from a few base stations to nationwide networks.
• Redundancy and reliability through modular architecture.
• Open interfaces for integrating other technologies.
• Support for hybrid networks where TETRA and LTE/5G work seamlessly together.
• High availability and cost efficiency.

An example of this advanced technology is the DIB-R5 outdoor base station, which HMF will present at the upcoming Romanian Security Summit: robust, powerful, and optimized for critical operating conditions.

Mobile communication: handheld and mobile radios

Beyond infrastructure and systems, HMF offers an extensive portfolio of mobile devices. This includes handheld radios such as the PT590, known for their ergonomic design, intuitive operation, strong performance, and rugged construction. The range is complemented by mobile radios and third-party solutions that can be seamlessly integrated into existing networks via open interfaces.

In addition, HMF supports hybrid communication devices capable of using both TETRA and MCX services. This opens up entirely new possibilities for emergency services: classic push-to-talk functionality is enhanced with broadband applications such as video conferencing, database queries, or access to digital situation maps.

 Safety that creates trust

In public safety, it’s not only speed that matters, but also security and reliability. HMF solutions meet the highest standards for data protection, encryption, and network stability. Interoperability tests conducted as part of international MCX Plugtests™ have repeatedly confirmed compliance with European Telecommunications Standards Institute (ETSI) requirements.

For emergency services, this means whether it’s voice communication, data transmission, or live video streams—all information remains protected while still being available in real time.

Live demos at the Romanian Security Summit 2025

Romanian security organizations will soon experience this firsthand. On November 5–6, 2025, HMF Smart Solutions will showcase its solutions in live demonstrations at the Romanian Security Summit in Bucharest (ROMEXPO). Visitors to the HMF stand will see how the convergent communication platform combines TETRA and MCX, discover the potential of modern MCX applications, and explore how the latest generation of end devices supports field operations.

A special highlight will be the presentation by Tsvetomir Benchev, Sales Director East & South Europe & BeNeLux, on November 6 from 10–11 a.m. in the Sherlock Holmes Hall. His talk, “Securing the Future with HMF: Mission-Critical Communications for Public Safety & Beyond”, will demonstrate how HMF is shaping the future of secure communications.

Future-proof communication for Europe

By combining proven TETRA technology with modern MCX communication via LTE/5G, HMF Smart Solutions is setting new standards for mission-critical communication in Europe. This enables authorities and organizations to modernize their systems step by step—without compromising the security and stability of established networks.

HMF’s mission is clear: communication without compromise—available when it matters most.

Building on the proven success of its MCX Series, Hytera launched the PNC660, its latest mission-critical ruggedized smart device, at MWC 2025 earlier this year. PNC660 elevates connectivity by harnessing the full power of 5G/LTE networks, delivering unprecedented speed and reliability for critical communications. Combining advanced mission-critical communication capabilities, multi-layered security features, and a user-centric design, the PNC660 is the ideal communication solution for sectors such as public safety & security, airports, and energy.

Compliant with 3GPP Release 15 standards, the PNC660 supports Mission-Critical Push-to-Talk (MCPTT), MCVideo, and MCData, enabling seamless voice, video, and data communication over 5G/LTE networks. This ensures low-latency, real-time communication, crucial for enhancing situational awareness and decision-making in high-stress environments. With QCI values of 65/66/67/69/70, the PNC660 guarantees reliable connectivity even in demanding conditions. Furthermore, eMBMS technology optimizes network efficiency, enabling real-time multimedia communication for both public safety and industrial users.

Unmatched Security and Enterprise Mobility Management

Security is a top priority for the PNC660. The device is equipped with multi-layered security protection, including an independent security chip compliant with IC/COS CC EAL5+ standards, alongside robust encryption and key management mechanism.
