INTRODUCTION
In 1981 analogue cellular was introduced and at about the same
time there was a joint Franco-German study looking at digital
cellular technology and the possibility of making a pan-European
system.
In 1982 a special working committee, Groupe Spécial Mobile
(GSM), was formed within the CEPT to look at and continue the
Franco-German study.
In 1986 the working committee was taken a step further by the
establishment of a permanent nucleus of people to continue the
work and create standards for a digital system of the future.
About a year later, the memorandum of understanding, or MoU,
as it is referred to, was signed by over 18 countries. It stated that
they would participate in the GSM system and get it into
operation by 1991.
In 1989 GSM was moved into the ETSI (European
Telecommunications Standards Institute) organization. Once
under the control of ETSI, the GSM system had it's name
changed to Global System for Mobile communications. The
committees working on the system changed from GSM to SMG
(Special Mobile Group). These changes avoided confusion
between the system name (GSM), and the people working on the
specification (SMG).
