Adequacy of dedicated system and hybrid networks with end-users needs:
PMR networks are designed to meet the precise and high demanding requirements of Public Safety forces. They provide a reliable and secure communication networks, with a higher level of security, robustness, availability and reliability than commercial terrestrial networks. Future standards are under definition and/or standardisation.
Satellite systems are essential. They are the only way to deploy quickly a secure, reliable and high data rate network on the theatre, providing connectivity between the end-users on a worldwide coverage, even when terrestrial infrastructures are destroyed or do not exist. Nowadays, there is no dedicated system to Public Safety and commercial MSS are largely used in operations.
Therefore, hybrid (satellite and PMR) systems are well adapted to meet the set of requirements, providing reach back capacity, global coverage and availability in urban or rural areas.
Dedicated systems allow to focus on the specific requirements and to provide the most adequate communication capabilities.
A combination of future PMR networks and new dedicated satellite segments to Public Safety would provide the most efficient communication networks in the mid and long-term horizons.
Dedicated satellite segments to Public Safety operations:
A preliminary design of a dedicated satellite segment has been proposed to meet the needs of mid-term horizon, composed of three missions:
- Multispot S-band mission over EMEA,
- European Ka-band multispot mission,
- African Ku-band steerable mission.
An initial design and sizing exercise of satellite antenna and payload has assessed its technical feasibility based on existing or soon-to-be-ready technologies – resulting from previous R&D.
One of the most promising accommodation solutions has been proposed on a single Alphabus platform.
Organisational, political and business feasibility
A large panel of European institutional bodies has been interviewed in order to assess the political willingness and organisational feasibility of a future Speed system, providing heterogeneous visions and different perspectives.
If Satcom is perceived as an essential part of the telecommunication capability, it is not always clearly stated as an urgent policy priority. The lack of rationalised demand among the different Public Safety end-users is clearly assessed. And the willingness to set up an ambitious programme is limited by the budget crunch and previous costly experiences even if the requirements are real from an operational-oriented institutions feed-back.
On the business side, a PPP approach seems to be the best compromise to raise the commitment of the majority of stakeholders. To ensure the success of such ambitious program, an attractive business plan needs to be consolidated.
