|---|---|---|
Supplying radio spectrum for all demand is challenging. Licensed Shared Access (LSA) is a technology to allow different types of spectrum users to share radio spectrum. The current spectrum sharing systems are mainly based on propagation modeling. There are also a few examples of using spectrum sensing of the primary signal. Sensing the secondary spectrum user is a novel interference protection concept, and validation and piloting is required to find out its applicability in real environment. An end-to-end demonstration system was built together with mobile network operators, broadcasters, network vendors, technology providers, academia and the regulator to test the concept in spectrum sharing between LTE and Program Making and Special Events (PMSE) users in the 2.3 GHz band in Portugal. This paper presents the demonstration system, test setup results of the validation. Results showed that sensing of secondary signal at the receiver location of the primary user is an accurate and cost-efficient interference protection method for dynamic spectrum access. The system performed particularly well in the spectrum sharing arrangement, where the mobile network is always on, and the relatively high tower and high-power base stations are the main interference source. Furthermore, the concept was proven applicable in use cases where PMSE was deployed in a relatively small distinct area. The system can be deployed as a stand-alone setup or in combination with the propagation modelling-based methods. |
