The modern mobile phone is a more complex version of the two way radio, which was a very limited means of communication. As soon as the users moved out of range of each other’s broadcast area, the signal was lost. In the 1940s, researchers began experimenting with the idea of using a number of radio masts (天线塔) standing around the countryside to pick up signals from two-way radios.

The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modern mobile handset. Within a decade, mobile phones became available to the public. The streets of modern cities began to feature sharpsuited characters shouting into giant plastic bricks. In Britain the mobile phone quickly became synonymous (等于) with the “yuppie”, the new breed of young urban professionals who carried the expensive handsets as status symbols. Around this time many of us swore that we would never, ever own a mobile phone.

But in the mid-90s, something happened. Cheaper handsets and cheaper calling rates meant that, almost overnight, it seemed that everyone had a mobile phone. And the giant plastic bricks of the 80s had evolved into smooth little objects that fitted nicely into pockets and bags. Cities suddenly had a new, postmodern birdsong.

Alexander Graham Bell would be amazed if he could see how far the science of telephony has progressed in less than 150 years. If he were around today, he might say: “That’s gr8! But I’m v busy rite now. Will call U 2nite.”
