This paper presents interference measurements for spectrum sharing between Long-Term Evolution (LTE) network and wireless cameras in the 2.3–2.4 GHz band under the new Licensed Shared Access (LSA) concept. The introduction of wireless broadband (WBB) communications services in this band is currently under study in European regulation and standardization. If the band cannot be cleared, a potential implementation option is the LSA approach, which maintains the protection of the current incumbents while introducing WBB as an additional licensed system within the band. Defining the incumbent protection criteria is critical and will require field measurements. The incumbents operating on the band in Finland and many other European countries are Programme making and special events (PMSE) wireless cameras. This paper presents results from an interference measurement campaign conducted in Ylivieska, Finland, where the aim was to study the interference from real LTE WBB system to a professional level wireless camera link on the 2.3 GHz band using the Finnish LSA trial environment. The measurements were planned to reproduce the cordless camera link scenario in ECC report 172, which provides compatibility studies with respect to the potential usage of the 2.3 GHz band for WBB systems. The results indicate that coexistence between LTE and wireless camera link can be feasible in the measured cordless camera link scenario in adjacent or larger separation channels. The measurement results are slightly less restrictive than the theoretical results in the ECC report, which came to the same conclusion about the feasibility. However, further study is required to derive actual incumbent protection criteria. |
