 Use cases (or applications)

The BLUESPACE architecture will serve 5G service provision in millimeter-wave regions of the spectrum. Proof-of-concept validations and a test-bed will be realized to demonstrate the merits and application of the BLUESPACE concept.

Technical and research challenges

  • The adaptation of DRoF schemes in parallel with ARoF techniques and their adaptation to SDM network with increased degree of integration and full compatibility among the two schemes
  • Development of advanced hardware solutions and modules for cost efficient ARoF transceivers, remote power distribution over SDM network for the independent powering RRUs from the CO, spatial optical beam forming schemes with simplified design requirements and direct compatibility with ARoF transceivers at the RRU, and compact SDM splitter and MCF adapters enabling advanced SDM-based ODN designs
  • The optimum allocation of the BBU pool at the CO and the design of its switching and interconnection hardware to enable SDM-compatible DCA, controlled strict latency and CoMP for both DRoF and ARoF paradigms
  • Design of optimized interfacing elements between the SDM media and the radiating elements in the RRU/RRH sites to enable advanced massive MIMO and beam steering solutions for both DRoF and ARoF architectures
  • The evaluation and design of SDN control to support SDM and NFV orchestration to deploy virtual base-band units (vBBUs) in the CO, as well as network slicing to support de virtualization of the network resources and multi-tenancy (e.g. verticals).

Expected impact

BlueSpace proposition offers unrivalled characteristics whose impact include:

  • Increased bandwidth provision by naturally enabling and supporting massive multiple Input Multiple Output (MIMO) in the Ka-band with seamless starting/ending interface with the fiber medium by exploiting space diversity in the RF domain with efficient beamsteering in the photonic domain, 
  • A compact infrastructure that is reconfigurable by means of Software Defined (SDN) and Network Function Virtualization (NFV) paradigms and with
  • Full integration with existing approaches for access networks such as Passive Optical Networks (PONs).
