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

Types of Tests and Measurements

Scope Tests Functional tests Coverage (outdoor drive tests and indoor walk

tests) EIRP pattern Carrier power reduction Speed tests Hand-over Interoperability Evacuation time

Regulatory compliance

Compliance with the I/N protection criteria (PMSE/FS) Propagation model EMF exposure

Business context * Carrier aggregation

Various tests have been planned and executed within the LSA Pilot

* In progress
