The handbook of optical communication networks
These factors are leading towards an integrated high-speed (and high-bandwidth) communication environment where all communication needs will be supported by a single communication network. The latest trends indicate that bandwidth needs double every 100 days. The volume of data traffic has surpassed the volume of voice traffic. Such a monumental demand for bandwidth can only be met by using optical fiber as transmission media. Other...

Broadband Powerline Communications Networks Network Design
Access networks implement the inter-connection of the customers/subscribers to wide-area communication networks. They allow a large number of subscribers to use various telecommunications services. However, the costs of realization, installation, and maintenance of access networks are very high, very often representing more than 50% of the investment in the network. Therefore, network providers try to realize the access network at as low a...

Introduction to Telecommunications Network Engineering
Telecommunications is one of the fastest growing business sectors of modern information technologies. A couple of decades ago, to have a basic understanding of telecommunications, it was enough to know how the telephone network operated. Today, the field of telecommunications encompasses a vast variety of modern technologies and services. Some services, such as the fixed telephone service in developed countries, have become mature, and some...

Implementing 802.11, 802.16, and 802.20 Wireless Networks
Communication, a word that many associate with modern technology, actually has nothing to do with technology. At its core, communication involves nothing more than the spoken or written word, and symbolic languages like art and music. Technology has become synonymous with communication because technology has historically been the method by which communication to or by the general population takes place. From the printing press to the...

Handbook of Wireless Networks and Mobile Computing
The past five decades have witnessed startling advances in computing and communication technologies that were stimulated by the availability of faster, more reliable, and cheaper electronic components. The design of smaller and more powerful devices enabled their mobility, which is rapidly changing the way we compute and communicate. For instance, the worldwide number of cellular phone subscribers has quadrupled in the last five years and has...

Communication plays a major role in every individual’s life. Computers are the best means to communicate when it comes to global communication. Computers on the Internet communicate using Transmission Control Protocol (TCP)/Internet Protocol (IP). An IP address differentiates one PC from the other Example of an IP address : 205.20.167.177 Programs within the system communicate with each other using Ports. Ports enable communication...
