The history of mobile phones begins with early efforts todevelop mobile telephony concepts using two-way radios
and continues through emergence of modern mobile phones
and associated services.
Radiophones have a long and varied history
going back to Reginald Fessenden's invention and shore-to-
ship demonstration of radio telephony, through the
Second World War with military use of radio telephony links
and civil services in the 1950s, while hand-held mobile radiodevices have been available since 1973. Mobile phone
history is often divided into generations (first, second, third
and so on) to mark significant step changes in capabilities

The technological development that
distinguished the First Generation
mobile phones from the previous
generation was the use of multiple cell
sites, and the ability to
transfer calls from one site to the next
as the user travelled between cells
during a conversation. The firstcommercially automated cellular
network (the 1G generation) was
launched in Japan by NTT in 1979. The
initial launch network covered the full
metropolitan area of Tokyo's over 20
million inhabitants with a cellular network of 23 base stations. Within five
years, the NTT network had been
expanded to cover the whole population
of Japan and became the first nation-
wide 1G network.
