Spectrum sharing developments exploiting cognitive radio technology will change the traditional spectrum management models, which calls for discussions and decisions in the policy making domain. Efficient governance of natural resources such as the radio spectrum requires actions in different policy making levels ranging from national level all the way to the international level. This Chapter will introduce spectrum sharing related policy making activities in the global level presenting the actions taken at the International Telecommunication Union Radiocommunication sector (ITU-R). We will introduce the groups within ITU-R and their related activities and introduce cognitive radio and spectrum sharing related terminology developed at the ITU-R. Special emphasis is put to the ITU-R studies on cognitive radio systems (CRS) with a set of capabilities for obtaining knowledge, decision making and adjustment, and learning, to enhance the efficiency of spectrum use. We will introduce the CRS capabilities and present scenarios and applications where vertical and horizontal spectrum sharing using CRS capabilities could take place. Other sharing related activities at the ITU-R are also presented including spectrum management, spectrum monitoring and spectrum occupancy measurement studies as well as more general ongoing work on regulatory tools to enable spectrum sharing and CRS from the point view of spectrum management. Finally, a future outlook is given for spectrum sharing policy developments towards the fifth generation (5G) networks.

“…Radio environment map (REM): REM is a centralized or distributed database, which combines environmental information, past experiences, and radio knowledge altogether [22,23]. REM includes information about device locations and their activities, spectrum use, coverage or interference levels, relevant regulations and policies, and services and networks.…”

“…REM includes information about device locations and their activities, spectrum use, coverage or interference levels, relevant regulations and policies, and services and networks. In addition to real measured data, REMs can be constructed further by interpolating the measurements to have predicted values of data at locations where there are no reported measurements available [22]. This information forms the basis of environment-aware network operations like planning, radio resource management, and troubleshooting.…”

“…One of the main trends within the development of wireless network architectures has been the many increase in their instrumentation. In such as the step-down of drive tests (MDT) in cellular networks, combined with enhanced measurement capabilities [3] across the protocol stack in mobile phones and wireless fidelity devices, are enabling network operators to reap new amounts of knowledge from their networks [4]. The information may be mined to optimize networks, increase security through anomaly detection, and supply and enhance application behavior, among alternative things.…”

Spatial big data acts as a important key role in wireless networks applications. In that spatial and spatio temporal problems contains the distinct role in big data and it's compared to common relational problems. If we are solving those problems means describing the three applications for spatial big data. In each applications imposing the specific design and we are developing our work on highly scalable parallel processing for spatial big data in Hadoop frameworks by using map reduce computational model. Our results show that enables highly scalable implementations of algorithms using Hadoop for the purpose of spatial data processing problems. Inspite of developing these implementations requires specialized knowledge and user friendly.
