Communications research theme

The Communications theme includes wireless and multimedia communications, 5G networks, smart devices and infrastructures, immersive environments, mobile infrastructure, media broadcasting and media streaming.

Examples of communications related projects are shown below:

SALUS

Public Protection and Disaster Relief (PPDR) agencies in EC member states are relying on digital Private Mobile Radio (PMR) networks for mission-critical voice and data communication. These networks are highly resilient and properly dimensioned to cope with crisis and emergency handling, and are well protected against monitoring and intrusion by means of encryption, authentication and integrity.

The two main standards for digital PMR networks in Europe are TETRA (TErrestrial Trunked RAdio) and TETRAPOL.The majority of these networks are based on mature technology, requiring old-fashion synchronous links (backbone), and using proprietary hardware solutions that eventually become obsolete. These networks also provide limited inter-technology coverage providing very ineffective management of emergency events, both at the national level and in cross-border regions. The main goal of SALUS is to design, implement and evaluate a next generation communication network for Public Protection and Disaster Relief (PPDR) agencies, supported by network operators and industry, which will provide security, privacy, seamless mobility, QoS and reliability support for mission-critical PMR voice and broadband data services.

The project covers the full techno-economic scope regarding development and deployment of the next generation PPDR networks by focusing on the integration with / migration to 4G wireless communications developments targeting three critical scenarios 1) city security, 2) disaster recovery, and 3) temporary protection. Salus will address key research challenges such as enterprise architectures, economic and business analysis, and a number of technical aspects concerning QoS, resilience, inter-systems handover (secure, seamless and fast), enhanced security, privacy mechanisms in heterogeneous network infrastructure, and multicast broadband PPDR services.

Innovative Quality of Experience Management in Emerging Multimedia Services (QoE-NET)

The project addresses the needs for models, methodologies and tools for an effective management of the QoE along the whole chain of design, production, delivery and control of multimedia services. Particular attention will be devoted to three applications: mobile gaming, social TV, and web-services.

Vocality

A novel solution capable of guaranteeing seamless, dynamic and reliable wireless communication over multiple communication bearers.

A knowledge transfer partnership (KTP) grant worth £262,000 has been awarded to develop new technologies enabling seamless, ubiquitous connectivity over wireless technologies.

The developed system will assess the quality of available communication channels including 3G, 4G, WiFi and satellite in real time and on the basis of the information gathered will select the fastest or most cost effective route. The solution will switch seamlessly between channels enabling users to optimise connectivity regardless of location. These new developments will have relevance to a number of key markets including government, military and the private sector.

CONCERTO

FP7 ICT CONCERTO (Content and cOntext aware delivery for iNteraCtive multimedia healthcaRe applications) is a STREP project in the EU's Seventh Framework Programme aiming at designing and validating several critical building blocks of telemedicine applications.

These include network-aware applications that rely on content-aware codecs and storage formats, carried over an application-aware network. The ultimate aim of FP7 ICT CONCERTO is to provide high a Quality of Experience (QoE) for medics, which is a necessary condition for providing flawless medical diagnosing of the highest reliability.
