GSM基础知识的介绍

GSM基础知识的介绍:

The Global System for Mobile communications (GSM) is a huge,
rapidly expanding and successful technology. Less than five years
ago, there were a few 10's of companies working on GSM. Each of
these companies had a few GSM experts who brought knowledge
back from the European Telecommunications Standards Institute
(ETSI) committees designing the GSM specification. Now there
are 100's of companies working on GSM and 1000's of GSM experts.
GSM is no longer state-of-the-art. It is everyday-technology,
as likely to be understood by the service technician as the ETSI
committee member.
GSM is quickly moving out of Europe and is becoming a world
standard. HP has become expert in GSM through our involvement
in Europe. With excellent internal communications, HP is in an
excellent position to help our customers, in other regions of the
world, benefit from our GSM knowledge.
