Infos

This book is intended to be used as both a text book and as an aide memoire handbook by forensic radio survey engineers, particularly those working for official police agencies. The book provides a simple but detailed overview of the operation of cellular networks (GSM, UMTS and LTE, US CDMAOne/CDMA2000, amongst others). In addition, the author also provides an overview of the technical theories that underpin cellular radio systems - basic radio theory and a simple explanation of the mathematical concepts that underlie measurements scales such as dB and dBm. The main part of the book, however, focuses on radio surveys, the various types of survey, the techniques employed for each survey and the considerations and potential problems that can be encountered when surveying different types of network. The final section deals with processing and interpreting the results of radio surveys and examines the information that can be gained from them.

Joseph Hoy is a telecoms engineer and trainer with 27 years of industry experience. He has worked extensively as a forensic cell site analyst and expert witness, contributing to many high-profile cases. He has undertaken the work of the forensic radio surveyor, capturing measurements of cellular coverage at crime scenes and other locations, and has also provided extensive training for cellular engineers, cell site analysts and forensic radio survey engineers.
