ENENSYS Technologies leads innovation in Critical Communications, crafting solutions that make the reliability and security of first reponders communications. By leveraging state-of-the-art technologies, ENENSYS tailors its offerings to optimize network performance and interoperability in demanding environments. With a focus on empowering first responders and decision-makers, ENENSYS develops and promotes innovative solutions for the next generation of critical communications at scale.

Having played a central role within 3GPP over the past decade developing the key MBMS/eMBMS components of the mission critical services (MCX) standards, ENENSYS Technologies is recognized by the global critical communications community for its solutions, which facilitate the efficient delivery of critical communications at scale. In particular, ENENSYS leads the market with its open, standards-based, end-to-end broadcast/multicast solutions.

By being an active member of industry associations such as TCCA, ENENSYS is able to contribute its knowledge and expertise to multiple working groups; in particular, the Critical Communications Broadband Group (CCBG) and Broadband Industry Group (BIG), where the global ecosystem of equipment and solutions providers, critical network operators, Government agencies and industry experts work together to accelerate the migration to advanced critical broadband solutions.

Notorious Collaborative Projects

Covera5Ge

Leader: ENENSYS

Partners: SIRADEL (Engie), Centrale Supelec, ENENSYS

Project type: RAPID https://www.defense.gouv.fr/aid/deposez-votre-projet/rapid-regime-dappui-linnovation-duale 

End date: 12/2023

The Covera5Ge project is set in the context of 5G PMR deployment for public safety communications applications. More specifically, two innovations are proposed in the project:

1. Optimization of radio resources for PMR 5G services: “intelligent” unicast / broadcast switching.
2. Optimization of PMR 5G infrastructure deployment: optimized planning at radio level (positioning of base stations or relays, microwave or fiber links).

NESTED

Leader: ATEME

Partners: Orange, Viacces Orca, INSA/IETR, ENENSYS

Project type: Region Bretagne

End date: 05/2023

The project has several objectives, addressing the societal, environmental and technical needs caused by video streaming:

1. Control the energy consumption of broadcast video networks using the latest compression and multicast technologies
2. Reduce broadcast and infrastructure costs by converging the standards used on different networks
3. Promote eco-responsible and controlled consumption of video to reduce the company’s carbon footprint, help reduce digital pollution and preserve the planet’s resources.
4. Improve quality of experience for end-users, in terms of latency and service personalization.

AMBRA

Leader: TDF

Partners: SDR Technology, TDF, INSA, ENENSYS

Project type: RAPID

End date: 08/2024

The AMBRA (Active Multistatic Broadcast Radar) project aims to test the potential of a new passive radar concept for air and sea monitoring, capable of locating and identifying moving objects by reusing the infrastructure and broadcasts of a cooperative digital terrestrial TV broadcast network. It is based on an invention patented by TDF that enables radar signals to be discretely inserted into specific frames of the 2nd generation DVB-T2 digital terrestrial TV broadcast standard in the UHF band, which is currently being deployed worldwide and will soon be introduced in France.
