Goals

To define and implement a testbed for LSA, developed in compliance with the national and European regulatory framework.

To verify the technical and regulatory feasibility of shared access based on LSA.

To assess coexistence between incumbent uses and LTE systems operating under the LSA.

Impact

The implementation of the LSA pilot allowed to investigate experimentally the shared access to spectrum in a fruitful cooperative context between the institutions and the world of industry and research.

The pilot has consolidated the role of Italy as a country heavily involved in the analysis of the potential and critical issues of the shared access to the spectrum to meet the growing demand for airwaves by different services.

Description

The Italian Ministry of Economic Development and the Joint Research Centre of the European Commission have realised a pilot project on the sharing of radio spectrum at 2.3 GHz band, based on the Licensed Shared Access (LSA).

The pilot is developed under the technical coordination of Fondazione Ugo Bordoni and involves industrial partners from several European countries.

The project represents a cutting edge initiative to delve deeper on the role that spectrum sharing has, as a tool to efficiently use spectrum and is in particular devoted to stipulate a suitable LSA framework and apply it in a real LTE network to assess performance and verify the compliance with sharing rules.

The proper regulatory and technical LSA framework has been identified, fundamental to allow the operation of the LTE test network, while granting due protection to the incumbent uses. Different sharing rules have been set for different type of incumbents considering the existing confidentiality requirements, which are challenging and quite peculiar of the Italian use case. A proprietary SW tool has been developed to define the sharing rules through coexistence analysis and assess the effect of mitigation techniques.

 

A novel specific measurement methodology, needed to detect interference levels well below noise, was identified using a sophisticated setup. Various tests on evacuation time have been conducted in the context of a distributed architecture to assess compliance with the evacuation time requirements.

 

The ETSI standard interfaces have been validated, thanks to a novel architecture to implement LSA through a distributed platform that can have deep impact on business processes and potential use cases. This last element is very relevant to future 5G networks.
