EDGE (Enhanced Data rate for GSM Evolution) is a specification for data transfer on GSM networks.
EDGE features both a packet capability, EGPRS (Enhanced General Packet Radio Service), and a circuit switched capability, ESCD (Enhanced Circuit Switched Data).
EDGE packs up to 69.2Kbps into eight timeslots, for a total theoretical bandwidth of 473.6Kb.
GERAN (GSM/EDGE Radio Access Network) is the name given to the 3GPP standards for GSM/EDGE radio access.
EDGE is an update to GPRS. In turn, EDGE will eventually be replaced by WCDMA (Wideband Code Division Multiple Access).
The Universal Wireless Communications Corporation has introduced a standard for EDGE over IS-136 TDMA networks. This standard has been named EDGE Compact.
EDGE Compact supports 384Kbits over the more limited bandwidth provided by TDMA networks.

EDGE for Mobile Internet
This ground-breaking resource offers you a detailed treatment of EDGE and its critical role in the development of the mobile Internet. The book explains how this global radio based high-speed mobile data standard can be introduced into GSM/GPRS networks, improving data transmission speeds to support multimedia services. It enables you to become thoroughly knowledgeable of EDGE specifications and covers concepts pertaining to several domains, including RF, signal processing, digital communications and communication networks.
EDGE for Mobile Internet opens with a review of GPRS principles and architecture, and then thoroughly explores the general principles, services and applications of EDGE as it relates to GPRS. It provides you with detailed coverage of a wide range of topics, including the RF physical, physical link, and RLC/MAC layers. The book also presents and analyzes WAP, and includes a guide to its related technologies such as wml, xml, mms, and wta. Case studies throughout the book present simple approaches to implementation problems, along with proposed resolutions.
GSM, GPRS and EDGE Performance : Evolution Towards 3G/UMTS
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 and GERAN features
* Presents field trial results for AMR and narrowband
* Provides EGPRS deployment guidelines
* Features a new chapter on Service Performance
GSM, GPRS and EDGE Performance : Evolution Towards 3G/UMTS is an invaluable reference for Engineering Professionals, Research and Development Engineers, Business Development Managers, Technical Managers and Technical Specialists working for cellular operators
Introduction to GPRS and EDGE: Technology, Operation, and Services
Introduction to GPRS and EDGE: Technology, Operation, and Services 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.
