“…A spectrum observatory network was built in a GlobalRF Spectrum Opportunity Assessment project [86,87,88,89,90,91,92] in Wireless Innovation between Finland and the US (WiFiUS) program [93], which was jointly funded by the National Science Foundation (NSF) [94] and Tekes [6]. The project built an international network of radio frequency (RF) spectrum observatories continuously collecting long-term spectrum data to study the trends in spectrum utilization and to identify frequency bands where spectrum sharing could be feasible.…”

This paper describes the design of a testbed for experimental validation and trialing of 5G vertical applications. The paper introduces the challenges that 5G aims to solve with regard to the spectrum demand and the convergence of different wireless communication services. The European-level 5G research program 5G Public Private Partnership (5G-PPP) is a coordinated European approach to secure European leadership in 5G. The 5G-PPP has developed a 5G Pan-European Trials Roadmap, which includes a comprehensive strategy for coordinated international preliminary and pre-commercial trials. The objective in designing Turku University of Applied Sciences (TUAS) testbed infrastructure in Turku, Finland, has been in building a testbed that can be used to contribute to the development, standardization and trialing of wireless communications in a diverse selection of scenarios and vertical applications. In addition, the paper describes the spectrum monitoring capabilities at TUAS facilities.

“…They are typically used to transmit video and audio wirelessly from a camera to an outside broadcasting (OB) van, and the typical users thus are the broadcasting companies. The spectrum occupancy of the 2.3 GHz band in a single location in Finland was studied using several weeks of spectrum measurement data from Turku spectrum observatory in [17,18].…”

“…In addition to the signals interpreted as wireless cameras, only a small number of higher power peaks, probably from narrowband amateur radio services, was detected. The wireless camera transmissions are very low power and difficult to detect, and the studies conducted with a professional level wireless camera in [18] demonstrate that the spectrum observatories are able to detect the wireless cameras only from distances smaller than 250 m. Thus, single-location spectrum occupancy measurements cannot be used to draw strong conclusions on the spectrum occupancy trends over large geographical areas.…”

This chapter studies the Licensed Shared Access (LSA) concept, which was initially developed to enable the use of the vacant spectrum resources in 2.3-2.4 GHz band for mobile broadband (MBB) through long-term static licenses. The LSA system was developed to guarantee LSA licensees a predictable quality of service (QoS) and exclusive access to shared spectrum resources. This chapter describes the development and architecture of LSA for 2.3-2.4 GHz band and compares the LSA briefly to the Spectrum Access System (SAS) concept developed in the USA. 5G and its new use cases require a more dynamic approach to access shared spectrum resources than the LSA system developed for 2.3-2.4 GHz band can provide. Thus, a concept called LSA evolution is currently under development. The novel concepts introduced in LSA evolution include spectrum sensing, short-term license periods, possibility to allocate spectrum locally, and support for co-primary sharing, which can guarantee the quality of service (QoS) from spectrum perspective. The chapter also describes a demonstration of LSA evolution system with spectrum user prioritization, which was created for Programme Making and Special Events (PMSE) use case.

“…The figure allows seeing when the transmissions have been operational, their power levels, and if there have been other signals or sources of interference present within the measurement band. The selection of correct parameters for recording such spectrum data is discussed in [97,133].…”

This article provides a survey and a general methodology for coexistence studies between digital terrestrial television (DTT) and mobile broadband (MBB) systems in the ultra high frequency (UHF) broadcasting band. The methodology includes characterization of relevant field measurement scenarios and gives a step-by-step guideline on how to obtain reliable field measurement results to be used in conjunction with link budget analyses, laboratory measurements, and simulations. A survey of potential European coexistence scenarios and regulatory status is given to determine feasible future use scenarios for the UHF television (TV) broadcasting band. The DTT reception system behavior and performance are also described as they greatly affect the amount of spectrum potentially available for MBB use and determine the relevant coexistence field measurement scenarios. Simulation methods used in determining broadcast protection criteria and in coexistence studies are briefly described to demonstrate how the information obtained from field measurements can be used to improve their accuracy. The presented field measurement guidelines can be applied to any DTT-MBB coexistence scenarios and to a wide range of spectrum sharing and cognitive radio system coexistence measurements.
