Leading the way towards 5G Mobile Broadband Networks
The use of spectrum in commercial applications is either licensed or license-exempted. Cognitive radio is another approach but it has been met with skepticism by cellular operators and has led to very limited deployments (e.g. 802.22). ADEL aims at facilitating the reform of spectrum licensing, highly improving the efficiency landscape for personal wireless communications, thus greatly benefiting the citizens. ADEL, while promising a technology breakthrough, also has the advantage of targeting the European spectrum allocation needs and constraints over the years to come. Carrying out the work at a European level will result in the advancement of wireless networking by European researchers and in the related commercial exploitation, providing partnership opportunities among ADEL partners and European players and stakeholders. Such efforts will energize investment, mobilize resources and create new job opportunities, while improving competitiveness in Europe. The consortium plans to release a few white paper contributions, framing the technical problem addressed by ADEL; the project will align and possibly contribute its results to the upcoming 5G standardisation activities and also present the LSA benefits to national and European regulatory bodies. The additional spectrum bands considered by ADEL for wireless broadband networks can mutually benefit both incumbent and LSA licensed operators.
- Key driver: To meet the growing capacity demands in cellular networks imposed by the increasing customer base and data- hungry mobile applications
- Key concept: The “Licensed Shared Access” (LSA) (a.k.a. “Authorised Shared Access” – ASA) paradigm wherein: incumbent operators may allow others to share their spectrum at specific times and places, according to an agreed set of rules.
- State-of-the-art: The use of spectrum in commercial applications is either licensed or license-exempt. Cognitive radio is another approach but it has been met with skepticism by cellular operators and has led to very limited deployments (e.g. 802.22).
To explore the potential of LSA as a key enabler of 5G mobile broadband networks by developing:
- Collaborative sensing techniques.
- Dynamic, radio-aware resource allocation.
- Cooperative communication.
The final goal of the project is to provide:
- 10 times overall improvement of capacity metrics (such as sum rate capacity, power constrained capacity).
- Minimize European operators’ CAPEX & OPEX investments.
- Reduce the global CO2 emissions and electromagnetic field exposure.
- Unlock harmonised spectrum across Europe.
- Manage spectrum more efficiently, in a way that guarantees the right of use of the different players.
- Improve wireless connectivity, QoS and energy efficiency with low-cost technologies, reinforcing Europe’s position in the world market.
- Guide the technical work in the direction of practical and commercially relevant R&D and pave the way for the adoption by wireless. operators of spectrum flexible wireless systems by 2020.
