The considerable growth of RFID is currently accompanied by the development of numerous identification technologies that complement those already available while seeking to answer new problems. Chipless RFID is one example. The goal is to both significantly reduce the price of the tag and increase the amount of information it contains, in order to compete with the barcode while retaining the benefits of a flexible reading approach based on radio communication. To solve the problem of the number of bits, this book describes the possibility of coding the information at the level of the...

Peering Carrier Ethernet Networks begins by providing background information on the evolution of important concepts and building blocks that have led to the current state of high bandwidth and high performance Ethernet technology in order to support current and emerging customer applications. The background information covered includes an overview of Public Switched Telephone Networks (PSTN) to describe circuit switching, multiplexing, and voice digitization that lead to the development of T1/T3 and SONET/SDH for transport. It interweaves these developments with changes in the...
