Microcontroller Based GSM/Gprs Projects $151.35 A microcontroller is a singlechip computer. Before the invention of the microcontrollers most intelligent systems were designed using microprocessors. A microprocessor is the processing element of a computer, consisting of an Arithmetic and Logic Unit (ALU) and the Control Unit (CU). A microprocessor on its own is useless and it has to be supported by a large number of peripheral chips, such as memory, inputoutput, timer, interrupt logic and so on. Currently there are many microcontroller chips manufactured by various companies. This book is based on using the highly popular PIn6F887 type microcontroller. GSM/GPRS modems are used in all mobile phones. This book teaches the basic principles of microcontrollers and shows how they can be used in GSM/GPRS based communications projects. All of the examples and the projects in the book are based on the highly popular mikroC language, developed by mikroElektronika.

GPRS Networks $140 GPRS is a packet based wireless communication service that offers data rates from 9.05 up to 171.2 Kbps and continuous connection to the Internet for mobile phone and computer users. GPRS is based on GSM communications and complements existing services such as circuit switched cellular phone connections and the Short Message Service (SMS). GPRS represents the bridge between 2G and 3G mobile telecommunications and is commonly referred to as 2.5G. Implementation of GPRS requires modification of the existing GSM networks in that GSM is a circuit switched technology while GPRS is packet oriented. GPRS enables packet data (the same as is used by an Ethernet LAN, WAN or the Internet) to be sent to and from a mobile station - e.g. mobile phone, PDA or Laptop. WAP and SMS can also be sent using GPRS and individuals working with GPRS need to learn and understand how the mobile stations, the air interface, network architecture, protocol structures and signalling procedures must be modified. GPRS offers much higher data rates than GSM and can be combined with 3G technologies such as EDGE to give even higher bit-rates. It offers many benefits for customers and network operators: such as volume (rather then time) dependent billing and more efficient use of network resources. Due to the worldwide delay in implementing 3G solutions such as CDMA and UMTS the demand for GPRS is still growing. GPRS Networks : Offers detailed information ranging from standards to practical implementation Answers 'how' and 'why' rather than just simply re-stating GPRS specifications Provides comprehensive coverage in a single volume Essential reading for all telecommunications project managers, field engineers, technical staff in network operator and manufacturing organisations, GPRS application and service developers, Datacoms/IT engineers. The comprehensive coverage also makes this a superb reference for students of computer science, telecommunications and electrical engineering. |

GPRS in Practice $130 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. |

GSM, Gprs and Edge Performance: Evolution Towards 3g/Umts $48.69 GSM, GPRS and EDGE Performance - Second Edition provides a complete overview of the entire GSM system. GSM (Global System for Mobile Communications) is the digital transmission technique widely adopted in Europe and supported in North America. It features comprehensive descriptions of GSM's main evolutionary milestones - GPRS, (General Packet Radio Services) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users. AMR and EDGE (Enhanced Data GSM Environment), and such developments have now positioned GERAN (GSM/EDGE Radio Access Network) as a full 3G radio standard. The radio network performance and capabilities of GSM, GPRS, AMR and EDGE solutions are studied in-depth by using revealing simulations and field trials. Cellular operators must now roll out new 3G technologies capable of delivering wireless Internet based multimedia services in a competitive and cost-effective way and this volume, divided into three parts, helps to explain how: 1. Provides an introduction to the complete evolution of GSM towards a radio access network that efficiently supports UMTS services (GERAN). 2. Features a comprehensive study of system performance with simulations and field trials. Covers all the major features such as basic GSM, GPRS, EDGE and AMR and the full capability of the GERAN radio interface for 3G service support is envisaged. 3. Discusses different 3G radio technologies and the position of GERAN within such technologies. Featuring fully revised and updated chapters throughout, the second edition contains 90 pages of new material and features the following new sections, enabling this reference to remain as a leading text in the area: Expanded material on GPRS Includes IMS architecture (Rel'5) and GERAN (Rel'6) features Presents field trial results for AMR and narrowband Provides EGPRS deployment guidelines Features a new chapter on Service Performance An invaluable reference for Engineering Professionals, Research and Development Engineers, Business Development Managers, Technical Managers and Technical Specialists working for cellular operators |
