Many wireless communications channels consist of multiple signal paths from the
transmitter to receiver. This multiplicity of paths leads to a phenomenon known
as multipath fading. The multiple paths are caused by the presence of objects in the
physical environment that, through the mechanisms of propagation, alter the path of
radiated energy. These objects are referred to as scatterers. In the past, researchers
often Looked at ways to mitigate multipath scattering, such as in diversity systems.
Multiple-input, multiple-output (MIMO) systems, on the other hand, use multipath
diversity to their advantage; a MIMO system has the ability to translate increased
spatial diversity into increased channel capacity.

LIKE SO MANY OTHERS , THIS BOOK WAS WRITTEN BECAUSE WE COULDN ’ T FIND ONE LIKE IT . We
needed something to hand to all of those people who have come to us asking for “a good
book to read on RFID.” When we Looked for candidates we found some great books, but
most were aimed at electrical engineers or top-level managers, with very little for those of
us who are in between. This book is for developers, system and software architects, and
project managers, as well as students and professionals in all of the industries impacted by
Radio Frequency Identification (RFID) who want to understand how this technology
works. As the title suggests, this book is about RFID in general and not just the most
recent developments; however, because so much is going on in the area of RFID for the
supply chain and especially the Electronic Product Code (EPC), we have devoted consider-
able space to these topics. Regardless of the type of RFID work you may be doing, we
think you will find something useful here.
