The modern mobile phone is a more complex version of the two-way radio. Traditional two-way radio was a very limited means of communication. In the 1940s, researchers began experimenting with the idea of using a number of radio masts located around the countryside to pick up signals from two-way radios. Scientists referred to each mast’s reception area as being a separate “cell”; this is why in many countries mobile phones are called “cell phones”. However, because of the primitive technology, the “telephones” were enormous boxes in the 1940s.
The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modern mobile handset. As soon as his invention was completed, he tested it by calling a rival scientist to announce his success. Within a decade, the streets of modern cities began to feature sharp-suited characters shouting into giant plastic bricks. In Britain the mobile phone quickly became synonymous(同义的) 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 handset 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. In every pub and restaurant you could hear the bleed and buzz of mobiles ringing and registering messages, occasionally breaking out into primitive versions of the latest pop songs. Cities suddenly had a new, post-modern birdsong.
