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.
