Radiolocation in Ubiquitous Wireless Communication

Exploring applications of multi-antenna radiolocation in wireless communication, this volume fills the gap in the literature available today. The general principles and standards are presented, in addition to the author's research on the subject.

Thisvolumehasitsbeginningsinalaboratoryproject,developmentofaradiolocator for the Wi-Fi network that was growing by leaps and bounds on the campus of Indiana University at that time. What started as a very focused and practical attempt to improve network management, touched in its lifetime upon broader issues of the use of radio spectrum, design of system architectures for the wireless medium, and image formation outside the limits of geometrical optics. Ihaveintendedthisbookmostlyfortheaudienceofengineersandsystemdesi- ers, in the growing ?eld of radio communication among small, portable, ubiquitous devices that have become hybrid platforms for personal communication and p- sonal computing. It is also a book addressed to network professionals, people to whom radio is largely a black box, a medium that they usually rely upon, but s- dom fully understand. In fact, in the course of my work in the ?eld, I have witnessed, to my dismay, a wide disconnect between the networking world and the radio technology that n- working has come to depend upon so heavily. Perhaps, because digital wireless communication is seen as digital ?rst and wireless second, there is often a m- placed emphasis on its information-processingside, with the methodologycentered around the discrete symbol, and with little intuition of the underlying physics. I had it once suggested to me, in apparent seriousness, to use radio cards for intra-system communication within a radiolocator! Wireless communication is radio, plain and simple.

Klappentext

Radiolocation in Ubiquitous Wireless Communication discusses the application of multi-antenna radiolocation to the environment of fast, widespread wireless communication among portable devices.

The book features distinctive information such as a description of a real-time, single packet radiolocation methodology, a detailed description of the architecture of two generations of working prototypes, the question of integrating radiolocation and data reception, and addresses adaptive directional communication with radiolocated sources. A functioning implementation of the transceiver architecture with multi-antenna radiolocation is described in detail.

Radiolocation in Ubiquitous Wireless Communication fills a void in the current technical literature by presenting issues involved in locating mobile wireless network agents. This book is a valuable reference for system design engineers in the field of handheld and portable communication, as well as experts in wireless management and security.
