Early Mobile Networks
If you want to make a few calls when you’re on the move nowadays, you can get yourself a package that will give you a free phone, with unlimited calls and texts, as part of an affordable monthly payment plan. Back then, you had to be pretty well heeled in order to be able to afford to make just one call on a mobile phone!
The world’s first fully automatic mobile telephone system, memorably dubbed MTA (Mobile Telephone system A), was developed by Ericsson and was made available in Sweden in 1956. This was the first system that was able to operate without the need for a technician plugging things in at the transmitter base, but due to the valves it employed in its electronics, it was very energy inefficient and was extremely heavy. The invention of transistors in the early sixties paved the way for a lighter, less power-hungry model, the MTB. The MTB network had managed to get 600 well-heeled Swedes to subscribe to it by the time it was closed down in 1983, and as such could be considered much more successful than its predecessor.
