Roaming in Wireless Networks

Roaming in Wireless NetworksA cell phone’s roaming feature allows the user to get service when traveling beyond the boundaries of his/her service provider. Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services.

Cable Communications Technology

Cable Communications TechnologyCable is now as much in the broadband business as it is television. This book explains the fundamentals of coaxial cable technology and the DSP that controls it, along with the cable modem and voice over IP technology now drastically changing the cable operators’ business. Aimed at working engineers and technicians, it can also be used a textbook for the a basic cable communications course in a 2 year tech program.

Integrated Broadband Networks: TCP/IP, ATM, SDH/SONET, and WDM/Optics

Integrated Broadband Networks: TCP/IP, ATM, SDH/SONET, and WDM/Optics“In this reviewer’s opinion, the authors of this book sucessfully implemented two ideas. First, the book is split into chapters describing single technologies, such as TCP/IP, ATM, SDH/SONET, and optics/WDM, and chapters investigating crucial aspects of protocol interworking broadband networks. Second, using recent knolwedge about evolutionary trends in modern networking and issues important in real implementation of service integration, and changes in modern telecommunications business, the authors consistently recall the main ideas lying behind contemporary networking and describe how they are implemented by different technologies. This book is written for network engineers and students. Researchers can also find a unified description of protocols and ideas necessary for understanding modern networking issues. This book is undoubtedly a high-quality reference for all technologies building contemporary broadband networks, and can be used by either novice and experienced engineers. ”

DC Power System Design for Telecommunications

DC Power System Design for TelecommunicationsStraightforward, systematic approach for designing reliable dc power systems for telecommunications

Here is a must-have resource for anyone responsible for designing, installing, and maintaining telecommunications systems. The text explains how to design direct current (dc) power systems that operate at nominal voltages of 24 and 48 volts dc, use lead-acid batteries, and are installed in public network telecommunications systems and other exclusive-use environments. Rather than train readers to design systems by rote, the author gives readers the skills and knowledge to perform systematic analyses to make the best choices based on several economic, operational, electrical, and physical considerations.

OFDM and MC-CDMA: A Primer

OFDM and MC-CDMA: A PrimerWireless communications has witnessed a tremendous growth during the past decade and further spectacular enabling technology advances are expected in an effort to render ubiquitous wireless connectivity a reality.

Currently, a technical in-depth book on this subject is unavailable, which has a similar detailed exposure of OFDM, MIMO-OFDM and MC-CDMA. A further attraction of the joint treatment of these topics is that it allows the reader to view their design trade-offs in a comparative context.
