Trends in modern RF Spectrum Management
Carlos E. Caicedo Bastidas, PhD.

Abstract: Wireless communication services and associated applications rely on the use of radio frequency (RF) spectrum resources for their operation. Due to the growth in the use of these services, spectrum management agencies and wireless service providers need to create and establish flexible spectrum assignment mechanisms as a means to respond to the increasing demand for spectrum resources. Traditionally, frequencies within the RF spectrum have been "statically" allocated to wireless service providers, with restrictions imposed on the technologies to be used and the services to be provided. Thus, the lack of flexibility in current spectrum allocation and assignment methods has led to an artificial spectrum scarcity and an inefficient use of current spectrum resources. This has motivated the development of new technical, economic, and regulatory approaches for improved spectrum access that can accommodate and support the growing need for spectrum for current and new wireless services.

This tutorial will introduce and present the mechanisms and initiatives that regulatory and standardization entities are considering to modernize RF spectrum management. Technical, economic and regulatory elements that will foster the use of spectrum sharing and dynamic spectrum assignment mechanisms will be explained in sufficient detail for attendees to understand their benefits, tradeoffs and viability in the wireless service provision and spectrum management environments of the near future.

Future of Optical Communication Systems and Networks

Abstract: Optical communication based on fibre-optic has revolutionised telecommunications enabling high-speed (>100 Gb/s per channel) and high-capacity (>10 Tbit/s per fiber) transmissions over long distances (>1000 km). However, the proliferation of bandwidth-hungry services, such as high-definition TV, cloud computing and business applications has led to an ever increasing demand of Internet traffic. Therefore, significant research efforts in optical transport networks as well as dramatic changes in the optical networking paradigms are required.

The tutorial presents the main challenges and trends for the next-generation optical communication technology and optical networking. Topics such as channel modelling, advanced transceivers design, network planning and software defined networking are covered.
