Brief description of the project
The contract's objective is the design, development, and operational functioning of a unified national system of mission-critical wireless communications (MCNGR) for the personnel of the Hellenic Police, the Hellenic Coast Guard, and other Security Forces and relevant agencies operating in the field and contributing to security operations, search and rescue missions, and border management.
The new unified system will utilize alternative radio network technologies (MCx over 4G/5G, DMR Tier III, existing infrastructures, satellite, and VHF/UHF solutions) for resilience and operational continuity, ensuring full geographic coverage of the territory (land, sea, and air) and ensuring:
- Transmission of voice, image, and data (MCx services).
- High service availability to the end-user (user-perceived service availability).
- Service Continuity even in conditions of coverage loss, congestion, extensive disasters, or failure of individual infrastructures.
- Call prioritization on networks and secure encrypted communications throughout the signal transmission path.
The main objectives are:
- The transition from fragmented and technologically outdated communication systems, such as old voice systems per agency, to a unified National Mission-Critical Communications Infrastructure capable of securely, reliably, and operationally resiliently supporting all missions of the Security Forces.
- The establishment of a common, interoperable, and expandable communication framework for all Security Forces, achieving economies of scale, optimal utilization of public resources, and avoiding parallel or overlapping investments and fragmented infrastructures.
Through the implementation of the project, a national standard for mission-critical communications is formed, emphasizing infrastructure resilience, cybersecurity, interoperability, and operational continuity, significantly enhancing effectiveness, inter-agency coordination, and crisis management readiness at the national level. The system's central goal is to provide end-to-end Mission Critical services (MCPTT, MCData, MCVideo) with guaranteed availability, prioritization, and strong security, through the unification of all technological layers (4G/5G Access/Core networks, MCx, LMR/DMR, satellite means, terminals, and command and control systems (C2/C3)).
The nationwide coverage and unified architecture ensure operational continuity and coherence of actions in the field. Through this unified infrastructure, continuous operational awareness and real-time decision-making are achieved, aiming for optimal resource utilization, reduced response times, and enhanced overall operational effectiveness. The services provided by MCNGR to its users will be prioritized according to QPP (Quality prioritization and pre-emption) throughout their transmission, whether in access (RAN), transmission (IP/Mw), or termination (Core) of the network. The transmission of these services will precede any other type of communication carried by the contractors' networks at any time. It will offer geographic coverage throughout the Greek territory, land, and sea, at a rate of ≥95%. It will offer population coverage throughout the Greek territory at a rate of ≥98%.
This tender was designed following the study and analysis of similar national mission-critical communication projects being implemented in Europe and internationally, such as in the United Kingdom, Finland, France, Sweden, as well as the United States, Australia, and South Korea. These countries have advanced to modern 4G/5G infrastructures to support public safety services, aiming to ensure operational continuity, interoperability, and communication resilience in crisis conditions.
Structure of the Tender
Utilizing international experience and adapting it to national operational and geographical particularities, the tender is structured into four (4) distinct Sections ensuring transparency, technological neutrality, competition, and operational resilience, with the ultimate beneficiary being the citizen and the effectiveness in protecting human life. The tender is structured as follows:
Section 1: Provision of specialized project management consulting services, technical support, supervision, and confirmation of availability and interoperability, as well as evaluation of the level of provided services (SLA), with guaranteed independence from the other Sections.
Section 2: Supply of equipment, software, and applications of 3GPP MCx and 4G/5G Core technologies, command, control, and incident management systems (C2/C3) with the provision of service licenses for installation, operation, configuration, training, and multi-year support.
Section 3: Provision of access, usage, and connectivity services to a mobile network (4G/5G), with prioritization mechanisms (priority), as well as supply and provision of hosting and operation services for the DMR network, with end-to-end assurance of interoperability, operational availability, and 24×7×365 monitoring and technical support of the service and involved systems, training, and multi-year support.
Section 4: Supply and commissioning of terminal devices for the MCNGR Network (personal, vehicular, and portable), including central device management systems (MDM/UEM), and provision of management services (logistics) for configuration, network integration, user training, and multi-year support.
All Sections explicitly provide for defined, binding, and complementary obligations concerning the interoperability, information security, and cybersecurity of the system, with clearly defined and measurable levels of provided service (SLAs), as well as detailed allocation of responsibilities, roles, and duties among the contractors of the individual Sections.
These obligations will be further specified in the contractual documents and will be reflected in binding cooperation, interoperability, and implementation agreements, which will form an integral part of the contracts, ensuring the unified, secure, and uninterrupted operation of the project as an end-to-end service, to the benefit of the Security Forces operating in the field.
The Ministry looks forward to the substantial contribution of the market and interested parties to a project of national significance, so that the final tender document incorporates best technological and operational practices and ensures the creation of a modern, resilient, and interoperable national mission-critical communications infrastructure.
