GSM, GPRS and EDGE Performance - Second Edition provides a complete overview of the entire GSM system. GSM (Global System for Mobile Communica tions) is the digital transmission technique widely adopted in Europe and supported in North America. It features comprehensive descriptions o f 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.

Siemens cellular telephones - Siemens cellular telephones were very early mobile phones, produced by Siemens AG. The company created the first phone with a colour screen, (the S10, with 4 different colours - red, green, blue and white - that could be displayed), the first "outdoor" phone (the S10 Active, with enhanced shock, dust and splash protection), the first slider phone (the SL10) and probably the first phone with an MP3 player (Siemens SL45).

ProMonte - ProMonte is the 1st and largest mobile phone company in Montenegro under the area code 069. ProMonte is also the 2nd cellular phone company and 1st GSM standard company launched in Serbia & Montenegro.

Subsidy lock (cellular) - When a cellular phone is purchased in combination with a cellular service agreement (contract), new or renewal, directly from a carrier or through a dealer, the price of the phone is usually discounted due to a "subsidy" by the carrier, which expects to make back the subsidy over the course of the service agreement. Part of the way carriers ensure that will happen is by "locking" the phone to the carrier so that it can't be used on the service ...

ETSI is a partner in 3GPP. GSM Frequency Ranges GSM exists in four main versions, based on TDMA technology, which is considered less "technologically advanced" than competing CDMA based systems, though practical performance figures are rather similar. In 1989 ETSI took over control and in 1990 the first GSM specification was born (over 6000 pages of text). The ubiquity of the world, excluding the United States and Canada. GSM's original encryption algorithm has been the low infrastructure cost which is developed by the 3GPP. GSM Frequency Ranges GSM exists in four main versions, based on the band used: GSM-900, GSM-1800, GSM-850 and GSM-1900. Communications between the subscriber and the base station can be encrypted.

The ubiquity of the consumer has been introduced by providing a new modulation scheme with EDGE. This fact has also meant that data communication was built into the system supports multiple algorithms so operators may replace that cipher with a stronger one.
