Item description for Introduction to GPRS and EDGE: Technology, Operation, and Services by Lawrence Harte...
This book explains how the GSM system has been modified to provide GPRS, EDGE, and EGPRS mobile packet data services. Explained are the GPRS and EGPRS packet control channels and gateways to the GSM system to provide a maximum delivered packet data transmission rate of approximately 474 kbps. You will learn how EDGE is an evolved version of the GPRS radio channel that uses new phase modulation and packet transmission to provide for advanced high-speed EGPRS data services.
The GPRS system allows cellular service providers to upgrade one or more GSM radio channels (with changes) to provide broadband medium-speed and high-speed data services to their customers. GPRS and EGPRS technology is an "always-on" system that allows users to browse the Internet without complicated dialup connections.
You will discover that the key types of GPRS and EGPRS devices include external radio modems, wireless PCMCIA cards, embedded radio modules, and mobile telephones. External radio modems allow the customer to simply plug in their GPRS device to their USB or Ethernet data port to their desktop or laptop computer. GPRS PCMCIA cards can be added to most laptop computers or embedded radio modules allow devices such as PDAs and Laptops to integrate high-speed wireless without adding PCMCIA cards. Some mobile telephones include both GSM (voice and low speed data) and GPRS (high-speed packet data) capability.
Because the needs of voice and data communication are different, the operation of the GSM radio channel is different. GPRS devices can have single mode (only GPRS/EGPRS) or dual mode (both GSM voice and GPRS data) capability. You will discover how the GPRS system was modified using EDGE technology to increase the 171.2 kbps GPRS maximum data transmission rate to 474 kbps EGPRS data transmission rate.
This book provides the basic technical components and operation of GPRS technology. You will learn the physical radio channel structures of the GPRS system along with the basic frame and slot structures. Described are the logical channels and their functions. Explained are the key GPRS network components and how they communicate with each other.
Explained is the fundamental capabilities and operation of the GPRS and EGPRS radio channel including asymmetric data rates, modulation types (GMSK, 8-PSK), and how GPRS devices can use either GSM or GPRS control channels to setup and manage packet data communication sessions. You will discover how a packet control unit (PCU) coordinates the allocation of GSM voice channels and GPRS/EGPRS packet data channels and how a single GSM radio channel can provide up to 8 simultaneous data sessions and how many other users (possibly 80 per channel) can be added who have a 10% usage activity factor.

Reviews - What do customers think about Introduction to GPRS and EDGE: Technology, Operation, and Services?
Don't Buy Feb 27, 2006
Very disappointed. I purchased Introduction to GSM, Introduction to GPRS and EDGE, Introductin to EVDO all by Lawrence Harte.
All three were very superficial, with most of the material in each publication being used in the others. This is not serious publication - you can get as much information just searching the web. Save your money for serious texts.
I do not recommend any publications by this author.
