LSA Pilot Objectives
To support the RSPP objective of efficient use of spectrum To test the CEPT and ETSI frameworks on spectrum sharing with
focus on 2.3-2.4 GHz band (ref: EC Mandate of March 2014) To validate the LSA sharing framework for the Italian NRA Applicability of LSA approach to other frequency bands ? Use cases: Fixed Service; PMSE; Telemetry

Practical Aspects in Measurements
A: Testing the broadband functionality of the system in various locations on-site and around the site
B: Testing the LSA Protection Requirements Protection criteria imply the need to measure signals below the
noise floor Urban canyon around the deployment site meant that line of sight
was difficult to achieve to do functional tests in many outdoor locations
Accessibility of site / portability of equipment
