The Shared Spectrum Service, Technology and Network Provision in Mobile Communication

This text describes some developments of an explosive growth in mobile traffic demand. The growth has led to market driven approaches and need for more effective spectrum access and management. Regulatory, technology and economic issues have led to innovative strategic approaches and policies for more effective spectrum usages. This text seeks factors and possibilities to influence spectrum sharing and use of additional spectrum in mobile communication. Wireless network architecture defines functionalities, which impact on mobile subscriber’s behavior both technically and economically. If telecommunication services fit together, interfaces between elements and services are the key. Economic assets form a new shared spectrum access, which means ubiquitous technical functionality, new service architectures and interfaces between different radio networks in the value-added chains. The modern radio networks form bit-pipes for added value services. For different stakeholders there are technology environment, economic environment and content wish environment in search for additional spectrum utility.
