WiMAX Act 2: 802.16m provides evolution path to 4G
As current-generation 802.16e mobile WiMAX networks are deployed globally, work continues on the next generation of the technology known as 802.16m, which will provide greater performance, capacity and flexibility over existing legacy networks. More...2010 Wireless Industry Outlook
While the general sentiment for the passing of 2009 has been "thank God that's over," the year ahead will be characterized as one of steady progress but will fall far short of euphoric growth. More...Nortel unveils commercially available 100G optical system
Nortel says it has unveiled the industry's first commercially available 100G solution and announced that Verizon has deployed the system in its live customer network in Europe. More...Mobile WiMAX at 3.5 GHz starting to take off
European operators are leveraging improvements in technology and 3.5GHz spectrum to offer true mobile WiMAX networks. New operators such as Imagine Communications in Ireland begin the launch of nation-wide coverage. More...Microwave Photonics
Microwave photonics is an important interdisciplinary field that, amongst a host of other benefits, enables engineers to implement new functions in microwave systems.With contributions from leading experts, Microwave Photonics: Devices and Applications explores this rapidly developing discipline. It bridges a gap between microwave and photonic engineering, providing an accessible interpretation of the current available research material and a detailed introduction to various aspects of the area.
Opening with an overview to the subject, this book covers direct modulation, photonic oscillators for THz signal generation, and terahertz sources. It takes a unique application- focused approach and describes:
- analogue fibre-optic links;
- fibre radio technology;
- microwave photonic signal processing;
- measurement of microwave photonic components, and;
- biomedical applications.
This text is ideal for practising microwave and fibre optics communication engineers wishing to improve their knowledge, and for researchers and graduate students wanting an overview of the subject.
Fiber Optics: Physics and Technology
This book is a comprehensive source about optical fibers: Their structure, their light-guiding mechanism, their material and manufacture, their use. Several effects tend to degrade the signal as it travels down the fiber: they are spelled out in detail. Nonlinear processes are given due consideration for a twofold reason: On one hand they are fundamentally different from the more familiar processes in electrical cable. On the other hand, they form the basis of particularly interesting and innovative applications, provided they are understood well enough. A case in point is the use of so-called solitons, i.e. special pulses of light which have the wonderful property of being able to heal after perturbation.The book starts with the physical basics of ray and beam optics, explains fiber structure and the functions of optical elements, and continues to the forefront of applications. The state of the art of high speed data transmission will be described, and the use of fiber optic sensors in metrology is treated.
The book is written in a pedagogical style so that students of both physics and electrical engineering, as well as technicians and engineers involved in optical technologies, will benefit.
