GPRS in Practice: A Companion to the Specificationsby Peter McGuiggan
Synopses & Reviews
GPRS is now an established technology allowing packet-data access to the internet and intranets and it is expected that consumer demand for the service will continue to increase, especially when the higher data rates are made available.
The GPRS technology is also carried forward to the 3G systems and it is vital that engineers working in the GSM/3G engineering fields understand the GPRS technology.
The specifications are the source for the technology, but in general the specifications provide exactly that - specifications and not explanations! With this in mind, GPRS in Practice is written in a simple manner using simple language allowing the reader to fully understand the complex GPRS concepts and how the GPRS interface works.
Professionals quickly discover that, although the technical specifications for GPRS cover all parts of the engineering functions in detail and depth, they are lacking in one important feature; the conceptual framework within which the specifications sit - GPRS in Practice fills this gap. By beginning with an explanation of why GPRS is necessary and describing the core concept of GPRS operations, the TBF (Temporary Block Flow), a revision section then covers the GSM Air Interface with its Radio, Physical and Logical channels and this progressively leads to the GPRS logical channels - what they do and how they do it. The book then moves on to a brief introduction of the GPRS protocol stack which provides a launch pad for a detailed trip into all the layers of this stack, with detailed diagrams and explanations of each layer integrated into an overall understanding of how the GPRS service operates in practice.
An invaluable resource for Mobile network operators, Development and deployment engineers and Handset designers.
About the Author
Peter McGuiggan has worked in telecommunications for the past forty years. He has held a variety of positions such as development test-engineer for a telecommunications manufacturer, an engineer working on fixed line international telecommunications systems including satellite, microwave and line transmission systems and as a lecturer in radio systems and advanced electronics and an engineering manager. He also worked in Saudia Arabia managing the telecommunications training for the National Guard.Upon the privatisation of UK telecommunications in 1986, he was appointed as the training manager of one of the new telecommunications operating companies and in 1992 he was appointed Training Adviser to the Director of Mobile Communications of a major operating company. He currently works as a Telecommunications Consultant for PMCG Consultancy Ltd in the UK where he has written and presented courses on the GSM Air Interface, The GSM A-bis Interface, Cell Planning, Cell Optimisation using Frequency Hopping, GPRS Operations and UMTS Operations.
