Gsm network architecture, GSM overview , what is 2G

GSM is an open and digital cellular technology used for transmitting mobile voice and data services operate at the 850MHz, 900MHz, 1800MHz, and 1900MHz frequency bands. GSM technology was developed as a digital system using the time division multiple access (TDMA) technique for communication purposes.

What is GSM and How does it Work? Electrical Technology

GSM900 is the original GSM system. It uses frequencies in the 900MHz band (numbered 1 to 124), and is designed for wide area cellular operation, with maximum output powers of 1W to 8W being allowed for mobile applications. A GSM Cell radius can measure 35Km or even up to 60Km depending on antenna pattern.

Design of a GSM-Based Biometric Access Control System. Dr. Adamu Murtala Zungeru. Access control systems restrict access to a secured premise or other secured devices (like a safe) only to authorized persons. In this design a biometric (fingerprint based) access control system was developed with added versatility: remotely Adding/Removing users.

This articles addresses the issues of how to design effective delta-sigma modulators for wireless receivers that need to support GSM, DECT, and wideband CDMA (W-CDMA) operation. A single-loop third-order modulator topology suitable for low power and high integration multi-standard receiver is described. 1 The trade-offs in the modulator design.
