A major milestone for Crosscall's 450 MHz strategy, paving the way for the deployment of a new generation of rugged, mission-critical mobile devices for critical infrastructure operators in Germany.
Crosscall is proud to announce that the CORE-Z6 450 has successfully completed the 450connect certification process and has officially joined the whitelist of approved voice terminals for use on Germany's 450 MHz network.
This certification marks a key milestone following several months of development, testing, and close collaboration between the Crosscall and 450connect teams. As part of this approval process, the CORE-Z6 450 was tested in three essential areas: network compatibility, cybersecurity, and industrial ruggedness, confirming its ability to meet the requirements of critical infrastructure operators (KRITIS) in Germany.
450connect operates Germany's national 450 MHz network dedicated to critical infrastructure operators. As the exclusive holder of the 450 MHz frequency until 2040, 450connect provides highly available and resilient communications designed to support the control, supervision, and protection of essential infrastructure.
With the CORE-Z6 450 approved for this network, Crosscall is introducing a new type of professional terminal to Germany's 450 MHz ecosystem: a rugged Android smartphone designed from the outset for mission-critical 450 MHz connectivity and the most demanding field operations.
Reliable communication when it matters most
Clear communication remains essential for critical field operations. The CORE-Z6 450 features a powerful front-facing speaker delivering up to 102.5 dBA, combined with AI-powered noise reduction of up to -60 dB, enabling users to hear and be heard even in the noisiest environments.
In addition to its native 450 MHz capabilities, the CORE-Z6 450 also supports public and private 4G/5G networks, as well as Wi-Fi 6/6E, giving organizations complementary connectivity options for broadband services and professional Android applications.
Designed for the most demanding field environments
Developed according to Crosscall's rugged engineering standards, the CORE-Z6 450 is built to withstand intensive professional use in difficult conditions. IP68 and IP69K certification, MIL-STD-810H compliance, resistance to repeated drops onto concrete, and up to 53 hours of battery life in mixed use: features that ensure operational availability throughout field missions.
Its compatibility with the Crosscall X-LINK™ ecosystem and professional mounting solutions enables seamless integration into vehicle mounts, charging stations, and field equipment, supporting users throughout their interventions.
CORE-Z6 450: Ready for today's critical communications. Designed for tomorrow's.
Today, the 450connect network is dedicated to critical voice communications for terminals such as the CORE-Z6 450. The device has been designed to fully meet these current needs while also being ready to support future developments in the network and its services.
Beyond voice, its Android environment, large display, powerful chipset, and front and rear cameras make the CORE-Z6 450 technically capable of supporting advanced digital applications: business applications, data sharing, and video communications. These additional features are not yet available on the 450connect network. However, if these services are deployed in the future, the CORE-Z6 450 is already equipped to enable organizations to extend their field operations, from critical voice communication to a broader range of digital applications.
A new milestone for Crosscall in the 450 MHz ecosystem
This 450connect certification marks an important step in Crosscall's ambition to establish itself as a leading European manufacturer within the 450 MHz ecosystem. The CORE-Z6 450 is the first concrete expression of this ambition, with other products, accessories, and services to come to build a complete ecosystem that meets the specific needs of critical infrastructure operators.
For energy and water operators, transport and logistics organizations, healthcare organizations, and other KRITIS operators in Germany, the CORE-Z6 450 offers a new choice: a professional 450 MHz terminal combining reliable field communication, Android-based business capabilities, and Crosscall ruggedness — all in a single device.
