The main focus of the book is the advances in telecommunications modeling, policy, and technology. In particular, several chapters of the book deal with low-level network layers and present issues in optical communication technology and optical networks, including the deployment of optical hardware devices and the design of optical network architecture. Wireless networking is also covered, with a focus on WiFi and WiMAX technologies. The book also contains chapters that deal with transport issues, and namely protocols and policies for efficient and guaranteed transmission characteristics while transferring demanding data applications such as video. Finally, the book includes chapters that focus on the delivery of applications through common telecommunication channels such as the earth atmosphere. This book is useful for researchers working in the telecommunications field, in order to read a compact gathering of some of the latest efforts in related areas. It is also useful for educators that wish to get an up-to-date glimpse of telecommunications research and present it in an easily understandable and concise way. It is finally suitable for the engineers and other interested people that would benefit from an overview of ideas, experiments, algorithms and techniques that are presented throughout the book.

Every action to protect archaeological heritage requires environmental transformations, especially when such interventions are aimed at make available (usable, accessible, readable even in the early stages of investigation) a site through a proper infrastructure of the area. An archaeological site is, in fact, a system characterized by complex interrelated relationships that must be supported by networks able to provide technological control of complex functions. In this regard, this research aims to study in particular the system of infrastructural networks (communication, energy supply, integrated water cycle) in the service of taking care of archaeological sites as well as the interaction with the ecological and landscape network that covers the area. The encounter between infrastructural networks and ecological and landscape creates a new type of network, that can be defined as "environmental" and which takes account not only of supply and flow of matter and energy, but also the needs of environmental subsystems water, air and soil. The research is also applied to the archaeological site of "the Villa di Pollio Felice" in the town of Sorrento, which, for the characteristics of the archaeological park with strong environmental and landscape values, is particularly suitable for the application of the aforementioned concepts.

Here we present a recent study done for power saving in the telecommunication apparatuses of Base Transceiver Stations (BTSs). Experimental test of a "power saving function" has been realized. Moreover a simulation "Montecarlo Algorithm" has been developed. Savings for the BTS transmission consumption has been estimated in about 20°A..
