Both ShaMROCK phases are built around PTToC technology for mission-critical group voice over LTE commercial networks.
ESI MOBILE SOLUTIONS SL
Barcelona SME building secure push-to-talk group voice systems for emergency services over commercial LTE networks.
Their core work
ESI Mobile Solutions (trading as GENAKER) develops secure professional mobile radio systems that run over commercial LTE cellular networks rather than dedicated radio infrastructure. Their core product replaces traditional mission-critical radio systems (TETRA, DMR) with push-to-talk-over-cellular (PTToC) technology, targeting emergency services, public safety agencies, and security forces that need encrypted group voice communications with high bandwidth. Through the ShaMROCK project they moved from concept validation to a market-ready product, proving both the technical feasibility and commercial demand for LTE-based secure comms. They are a product-oriented technology SME, not a research organization — their EU project activity funded real product development.
What they specialise in
ShaMROCK Phase 1 keywords explicitly cite 'Secure Comms', 'Mission Critical Group Voice Communication', and encrypted traffic over LTE as the central deliverable.
ShaMROCK was designed to meet the needs of emergency services requiring high-bandwidth secure field communications, replacing legacy radio infrastructure.
The ShaMROCK system exploits commercial LTE networks as the transport layer, implying expertise in LTE application protocols and network integration.
How they've shifted over time
Their entire H2020 activity (2015–2018) is a single continuous development arc: ShaMROCK Phase 1 in 2015 established market demand and technical feasibility for secure PTToC over LTE, while Phase 2 in 2016–2018 funded full product development and market launch. There is no meaningful shift in topic — the focus remained consistently on mission-critical mobile communications throughout. Because both projects are the same initiative in two funding stages, there is no evidence of diversification or pivot within the H2020 record.
Their trajectory points toward a commercialisation-focused company that used EU funding as a product development accelerator — future collaboration value lies in deploying or integrating their PTToC platform rather than in joint R&D.
How they like to work
ESI Mobile Solutions applied to the SME Instrument as a solo company both times, meaning they have no recorded consortium partners from their H2020 activity — they lead independently rather than joining multi-partner projects. This suggests a self-sufficient product team that uses EU grants to fund internal development, not to build research networks. Anyone wanting to work with them should expect a vendor or technology-provider relationship rather than a co-development consortium dynamic.
No consortium partners are recorded across either project — both were SME Instrument solo applications. Their H2020 network, in the traditional consortium sense, does not exist; their connections are likely commercial (customers, channel partners, telecom operators) rather than academic or institutional.
What sets them apart
GENAKER occupies a narrow but commercially valuable niche: turning commodity LTE networks into secure, mission-critical communication infrastructure for emergency responders, without requiring dedicated spectrum or proprietary radio hardware. In a market still dominated by TETRA device vendors, an LTE-native PTToC approach is cost-effective and future-proof as public safety networks migrate to broadband. Their SME Instrument Phase 2 grant (€1.28M) signals that external evaluators judged both their technology and their go-to-market plan as credible.
Highlights from their portfolio
- ShaMROCK (Phase 2)The largest grant (€1.28M) and the full development phase that brought the secure PTToC platform to market — the clearest evidence of a commercially validated product.
- ShaMROCK (Phase 1)The feasibility study that defined the market need and technical specification for LTE-based secure group voice, setting the foundation for the full product.
