SPEED-5G at joint 5G-PPP event in Turin
SPEED-5G was present at a joint 5G-PPP event, which was co-organised by the Flex5Gware project, co-located with the CLEEN 2017 workshop at the Telecom Italia Labs in Turin on 21-22 June 2017. The event attracted an audience of about 50 experts from the 5G PPP community.
In addition, SPEED-5G had a booth in the 5G Proof of Concept zone, which was staffed by Keith Briggs, BT, and Ioannis-Prodromos Belikaidis, WINGS ICT Solutions. At the booth they presented two demos – about hierarchical management for RAT/spectrum/channel selection (WINGS) and dense, unplanned, small-cell deployment, multiple mobile users (BT). In particular:
Demonstration on hierarchical management for RAT/spectrum/channel selection
The demo is motivated by the fact that 5G networks would need to exhibit capacity expansion capabilities for supporting enhanced services and advanced devices. The band of 3.5GHz is one of the candidates especially in very dense environments in order to support such services. Therefore during the event the benefits from SPEED-5G approach for RAT/spectrum/channel selection in very dense, heterogeneous environments are explained and demonstrated.
Demonstration on dense, unplanned, small-cell deployment, multiple mobile users
For a very large deployment of small cells, with randomly placed cells and UEs, and in the interference-limited case, we have an exact theoretical formula for the distribution of Shannon capacity across users. We propose to take this as a benchmark for achievable system performance in the un-optimized situation, and demonstrate the improvements possible with the SPEED-5G cRRM architecture and its optimization algorithms. The demo will consider the whole distribution of bitrate, not just the average or maximum. The demo software uses an accurate radio model, allowing estimation of SIR at UEs, which is then mapped onto a bitrate depending on the technology. Our propagation modelling takes into account the effects of different frequencies. We can thus show the benefits of multiple RATs, each with its specific parameters such as bandwidth and range of modulation schemes.
