GPRS in Practice: A Companion to the Specifications (0470095075) cover image


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.
  • Provides descriptions of why procedures are specified and then clearly explains how the specifications work in practice 
  • Provides a layered view of the GPRS protocol and deals in detail with each layer separately 
  • Includes numerous acronyms and abbreviations accompanied by their full meaning

An invaluable resource for Mobile network operators, Development and deployment engineers and Handset designers.
