Сборник задач с ответами и решениями предназначается студентам для самостоятельных занятий и закрепления знаний по курсам лекций "Основы построения телекоммуникационных систем и сетей", "Радиорелейные и спутниковые системы связи", "Проектирование телекоммуникационных систем", магистерского курса "Теоретические основы телекоммуникационных систем" и др. по специальности "Телекоммуникационные системы".

Carriers and service providers have united around the concept of the Next-Generation Network (NGN). Although leveraging a broad basket of Internet technologies, the NGN is not being planned as the next-generation Internet. In its intention and architecture, it is more accurately described as Broadband-ISDN release 2.0. The NGN is hard to understand because it weaves together so many distinct issues: technology, new kinds of product, a new kind of carrier organization as well as changes in the business model, industry value chain and the shape of a converged future industry itself. This book presents a unified analysis of the complex transformation process that is taking place in the fixed telecoms, mobile telecoms, and broadcast industries and outlines strategies for success.

Get hooked up without getting tangled up in cords, wires, cables or techno mumbo. With Wireless Home Networking For Dummies, you can go wireless without going mad. It shows you how to plan, install, secure, and use a wireless home network for PCs or Macs. See how easy it is to share your Internet connection, files, folders, printers, and other peripherals. Put your gaming console on your wireless network and play multiuser computer games—even online.

Digitally Assisted Pipeline ADCs: Theory and Implementation explores the opportunity to reduce ADC power dissipation by leveraging digital signal processing capabilities in fine line integrated circuit technology. The described digitally assisted pipelined ADC uses a statistics-based system identification technique as an enabling element to replace precision residue amplifiers with simple open-loop gain stages. The digital compensation of analog circuit distortion eliminates one key factor in the classical noise-speed-linearity constraint loop and thereby enables a significant power reduction.
Digitally Assisted Pipeline ADCs: Theory and Implementation describes in detail the implementation and measurement results of a 12-bit, 75-MSample/sec proof-of-concept prototype. The Experimental converter achieves power savings greater than 60% over conventional implementations.
Digitally Assisted Pipeline ADCs: Theory and Implementation will be of interest to researchers and professionals interested in advances of state-of-the-art in A/D conversion techniques.

As a network administrator, architect, or security professional, you need to understand the capabilities, limitations, and risks associated with integrating wireless LAN technology into your current infrastructure. 802.11 Wireless Networks: The Definitive Guide provides all the information necessary to analyze and deploy wireless networks with confidence.
Over the past five years, the world has become increasingly mobile. Traditional ways of networking have altered to accommodate new lifestyles and ways of working. Wireless networks offer several advantages over fixed (or wired) networks, with mobility, flexibility, ease and speed of deployment, and low-cost at the top of the list. Large productivity gains are possible when developers, students, and professionals are able to access data on the move. Ad-hoc meetings in the lunch room, library, or across the street in the café allow you to develop ideas collaboratively and act on them right away. Wireless networks are typically very flexible, which can translate into rapid deployment. Once the infrastructure is in place, adding new users is just a matter of authorization.

Optical networks, undersea networks, GSM, UMTS…The recent explosion in broadband communications technologies has opened a new world of fast, flexible services and applications. To successfully implement these services, however, requires a solid understanding of the concepts and capabilities of broadband technologies and networks.Building Broadband Networks provides a comprehensive, non-theoretical introduction to broadband networking. It clearly and thoroughly conveys the principles and the technical fundamentals of the high-performance technologies that enable the reliable delivery of media-rich voice, video, and data services. After a careful examination of ISDN and ATM technologies, it describes optical network solutions based on SONET/SDH, WDM, and DWDM technologies. It then explores Ethernet operations and services and introduces Frame Relay and Fibre Channel networks, DSL solutions, and wireline and wireless cable networks. The author reviews the capabilities of cellular technologies, describes the characteristics of wireless networking technologies, and examines broadband satellite networks.
