SPEED-5G value chain analysis
The SPEED-5G project is performing a value chain analysis for 5G. The project has been particularly exploring the implications of its novel three dimensional extended-Dynamic Spectrum Allocation (eDSA) model for stakeholders in the 5G value chain. This article presents some of the project’s initial insights.
Relevance of the eDSA model for stakeholders
SPEED-5G aims at breaking up the conventional wireless technologies framework by proposing a novel three dimensional extended-Dynamic Spectrum Allocation (eDSA) model. The three main dimensions of the model include:
- ultra-densification through small cells,
- additional spectrum,
- exploitation of resources across technologies.
This model is being investigated for indoor and indoor/outdoor scenarios where capacity demands are at the highest, but also where the eDSA is most effective at exploiting co-operation across technologies and bands. The analysis of the eDSA model under different scenarios is valuable for key stakeholders to decide not only their positions in the telecommunication market, but also business aspects arising from SPEED-5G key notions. These stakeholders are: operators, vendors, end users, services provider and regulators.
Operators will use the results of SPEED-5G to strengthen their positions in European collaborative research in telecommunication by acquiring knowledge in the important area of capacity increase by using small cells in 5G networks. For example, the ‘home-hub’ series of domestic small cells will be developed to have LTE added, but the roadmap beyond this depends on the success of flexible layer 1 and 2 as results from SPEED-5G. Moreover, operators will also use the results of SPEED-5G to move more vigorously and confidently into adjacent markets, such as IoT, both in building and for longer range. Finally, SPEED-5G outcome shall also identify possible gaps that need further research and this awareness will be used to steer future research directions of the telecom operators.
Vendors will play a very important role as one of the key stakeholders for SPEED-5G. Vendors will be encouraged to make new devices which will be compatible to SPEED-5G technologies. For example, these new devices will have multiple MAC interfaces (i.e. FBMC, OFDMA etc.) to download gigabytes of data faster than with currently available devices. New SPEED-5G devices will also lead to significantly enhancements in augmented reality, industry automation, and wearable devices.
End users will become the true beneficiaries of SPEED-5G and will experience a completely distinctive user experience in terms of “Mobile Internet” over Speed-5G Heterogeneous Networks (HetNets).
Service providers can utilize new features and services that SPEED-5G can provide, enabling them to deliver amazing infotainment services.
There is growing interest in Dynamic Spectrum Access (DSA) from regulatory agencies (e.g. FCC, Ofcom) and a variety of industry standardisation forums including IEEE SCC41, 802.11y, and 802.22. The SPEED-5G approach enables real-time optimization of spectral resources and radically changes spectrum management that depends on pre-planned frequency assignments. SPEED-5G targets bands below 5GHz which is also the main target of many regulators before next WRC in 2018. The regulatory stipulations for 5G technologies must be taken care of by the regulatory bodies. Although 5G technologies are in developing and evolving process it ought to be regularized for the betterment of deployment. The following aspects should be addressed in 5G regulation:
- Location Accuracy – More advanced accurate location finder in 5G.
- Lawful Intercept – The technical challenge is to develop a 5G architecture that enables communications not necessarily passing over centralized network elements, whilst ensuring compliance with lawful intercept regulations.
- Tower sharing – The 5G architecture should support solutions to minimize the number of antennas in shared multi-RAT environments.
- Flexible Spectrum Use – spectrum licenses should be flexible enough to allow operators to meet the rollout demand while being capable of using 5G spectrum for backhaul when and where appropriate.
- Accessibility – Broadband wireless services are becoming part and parcel of our daily life, so 5G services must have easy access to physically challenged people.
