Excerpt from the Book
3.1 INTRODUCTION
The history of GSM can be traced back to a proposal of Nordic Telecom at the CEPT (Conference of European Post and Telecommunication) in 1982, which purpose is developing a new digital cellular standard to satisfy the increasing demand of European mobile communication network.
The European Committee (EC) issued a recommendation which suggested the member nations who use GSM allowing communication in the frequency band 900MHz. The European Telecommunications Standards Institue (ETSI) then defined GSM after the digital cellular phone standard has been accepted worldwide.
This proposal was accepted on September 1987, when 13 managers and executive officers of CEPT GSM agree to sign the so-called GSM MoU “Club”, which is valid from July 1st, 1991.
GSM stands for Global System for Mobile Communications, formerly is Groupe Spécial Mobile.
The Global System for Mobile Communication (GSM) is a integrated and complete digital cellular communication system, which is first developed in Europe, and rapidly becomes popular throughout the world. This network is designed in corresponding with ISDN systems, and the services provided by GSM are the sub-systems of standard ISDN services.
