(Guest article by Vodafone<\/a>)<\/em><\/p>

Critical infrastructure providers such as the police, fire services, emergency services, transport operators, and energy suppliers face an increasingly complex challenge<\/strong>:<\/p>

They must be able to communicate in real time, securely, reliably, and in encrypted form<\/strong> \u2013 even under extreme conditions. MCX<\/strong><\/a> is a revolution in public safety and critical infrastructure communications. However, for applications such as these to function reliably, one thing is needed above all else across the board: high-performance, resilient mobile networks<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n Everything you need to know about MCX <\/p>\n

We have two further articles<\/strong> that examine the new MCX standard in detail.<\/p>

\u00a0<\/p>

Part 1<\/strong> looks at how MCX is revolutionising communications for public safety and critical infrastructure. This promising standard combines push-to-talk, data exchange, and live video for prioritised and fail-safe transmission over LTE and 5G. You will learn why traditional radio needs to be supplemented, how MCX bridges the gap, and the three pillars on which the new technology is based.<\/p>

\u00a0<\/p>


Part 2<\/strong> shows how the MCX standard translates into real-world operational communications. Teamwire and Frequentis demonstrate this: through the practical integration of Mission-Critical Services (MCX) into existing control centres and radio structures. The article provides a comprehensive overview of the current project status regarding MCX in practice.<\/p>

Without high-performance mobile networks, day-to-day operations today would be virtually impossible. Yet many public sector communication systems in Europe still rely on TETRA<\/strong> \u2013 a technology that supports voice transmission only and is based on the outdated 2G standard.<\/p>

But modern operational scenarios, large crowds or dynamic emergency situations demand far more:<\/p>

Real-time voice, photo, and video recordings<\/strong> provide emergency services with crucial additional information.<\/p>

This is precisely where Vodafone\u2019s LTE and 5G networks<\/strong> come in \u2013 with reliable, broadband mobile coverage that provides the foundation for modern, multimedia operational communications. Vodafone\u2019s 4G and 5G networks cover virtually all relevant frequency bands<\/strong> \u2013 from the 700 MHz range for coverage to 3.6 GHz for very high data rates<\/strong>. This means that sufficient capacity<\/strong> is already available for public safety organisations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

5G: more than just real-time transmission<\/h2>

Two key factors are crucial in emergency situations: time and security.<\/strong><\/p>

The latest generation of mobile communications delivers both. Communication via 5G is not \u2018just faster<\/strong>\u2019 and possible in real time; it also ensures the integrity and confidentiality of communications at all times through end-to-end encryption<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Roaming as a security concept: borderless networks instead of isolated solutions<\/h2>

To ensure that MCX functions reliably across national borders, a simple yet effective principle<\/strong> is required, and Vodafone is working closely with other organisations to implement this.<\/p>

In the current use case, this means:<\/p>

When emergency services operate abroad, their connections continue to run over their domestic secure network<\/strong>. This ensures that authorities always retain full control<\/strong> over their communications in critical situations.<\/p>

To ensure this connection remains stable everywhere, regardless of location, the required quality levels for voice, video, or data can be requested in other countries and provided there through roaming partnerships<\/strong>.<\/p>

The plan for the future is therefore as follows:<\/p>

If a device belonging to a critical infrastructure entity connects to a foreign cell, prioritised communication within the network is also ensured<\/strong> here. All content remains securely end-to-end encrypted throughout.<\/p>

In such cases, the public foreign mobile network serves merely as a \u2018guest network\u2019<\/strong>, providing the necessary bandwidth and prioritisation. In this way, a communication system usable across Europe<\/strong> will emerge that is secure yet functions flexibly across different mobile networks.<\/p>

A call for tenders from the BDBOS for roaming partnerships with German telecommunications providers is expected in Germany in the coming weeks. Final implementation of this principle is expected in the coming years.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Conclusion<\/h2>

Secure communication is the digital backbone for critical infrastructure organisations, for Germany, and for Europe. It not only lays the foundation for reliable cooperation<\/strong>, but is also the building block upon which everything relies in an emergency \u2013 and in the future, across national borders<\/strong> as well.<\/p>

This is precisely why reliable and resilient mobile networks<\/strong> in Germany and Europe have become indispensable: they provide the technical foundation<\/strong> that already meets the requirements of the police, emergency services, and other critical infrastructure institutions today.<\/p>

Solutions such as Mission-Critical Communications (MCX)<\/strong> are being consistently developed to enable communication that meets current requirements. Roaming and satellite solutions provide cross-border connectivity<\/strong> across Europe and ensure stability<\/strong> even when traditional infrastructure reaches its limits.<\/p>
