The first commercial
cellular network was launched in Japan by NTT in 1979. Fully automatic
cellular networks were first introduced in the early to mid 1980s (the
1G generation) with the Nordic Mobile Telephone (NMT) system in 1981.
This was followed by a boom in mobile telephone usage, particularly in
Northern Europe.
Today, besides voice and text data, video and TV services has driving
forward third generation (3G) deployment. And in the future, low cost,
high speed data will drive forward the fourth generation (4G) as
short-range communication emerges.
There are three major technical standards
for the current generation of mobile phones and networks, and two major
standards for the next generation 3G phones and networks. All European,
African and many Asian countries have adopted a single system, GSM,
which is the only technology available on all continents and in most
countries and covers over 74% of all subscribers on mobile networks.
