In addition to enhanced spectrum efficiency, the expansion of spectrum bandwidth and traffic offloading via WiFi, the deployment of small cells is considered one of the most promising strategies to accommodate the demand for broadband mobile services, particularly in indoor and outdoor environments over the next decade.

Implementing small cells within a macrocell coverage area results in a multi-tier heterogeneous network (HetNet), where various types of access nodes, including macrocells, femtocells, and relays, will coexist.

Although there is ongoing research and development on small cell/HetNet by both industry and academia, numerous challenges and questions remain for the successful deployment of small cells and HetNets.

These challenges include a fundamental lack of understanding of HetNet network capacity and the necessity for a Radio Access Network (RAN) Planning and Optimization (PO) tool for HetNet deployment in both indoor and outdoor environments.

Objective
Hetnet-smart-city

Our Approach

The DECADE project adopts the scheme of Research and Innovation Staff Exchange (RISE), with the effect of inter-sectorial efforts and knowledge integration to tackle the challenges in HetNet planning and optimization. The research consists in fundamental capacity analysis, system modeling, algorithm development, and performance engineering for HetNets. In addition, DECADE serves as a solid platform to promote long-term collaboration between academia and industry collaboration in a rapidly evolving area of Information and Communication Technologies (ICT) in Europe.
