This book provides an excellent overview of some of the different technologies that can be used to provide positioning solutions in support of location based services .This book will serve as good reference material for anyone interested in learning about opportunities and pitfalls in the development and deployment of in-door positioning systems for LBS

This descriptive, all-encompassing book is a must for anyone wanting to understand location-based services from infrastructure components to service deployment. The technologies and problems associated with LBS are described at length. The approach is non-technical and the author succeeds in explaining all concepts with hardly any formulas. The chapters are loaded with examples to illustrate past and current attempts to develop and deploy LBS both outdoor and indoor. The broad experience of the author with LBS is apparent at every page. In an attempt to be descriptive, the author omits to describe requirements and system specifications and performance.

It is relatively jargon free which is a positive Those readers with passing familiarity with sensors, engineering, radio, statistics, college level math and networks should have no trouble understanding the material well organized and easy to follow. It leads the reader through a lot of material at the proper depth of a primer provides sufficient depth and information for a semi-technical person to make informed decisions about the technology Comprehensive Good depiction of various signal processing techniques for resolving position and location Graphics and especially signal propagation graphics will help the reader understand limitations and environments that will cause issues The mapping/fingerprinting section is excellent Map-matching sections and explanation of geometric is very strong Explanation of models and data is excellent and appropriate.

When I began research about LBS several years ago, I found there was no book or survey paper that offered a quick overview of local positioning systems. This excellent work solves this problem. This book introduces several case studies, showing the details on how they are set up. Especially valuable is its detailed coverage concerning the infrastructure of building a LBS system. The most awesome thing is that this is the first book that clearly discusses how to deploy a LBS system. In summary, this is an excellent reference book for any researchers and engineers interested in developing a local positioning system.
