The US approach offered contracts to two companies in every city, which resulted in a confusing mish-mash of incompatible networks. The British government took a different approach. Too far apart and they would leave holes in the coverage; too close together and the signals would interfere with each other. The first base stations, large and heavy pieces of kit, were installed in During a trial period engineers drove around the country making calls to patient volunteers to test the signal strength.
They each expected to win up to 20, subscribers within ten years. To their astonishment, three years later they had over half a million subscribers, and network coverage reached 90 per cent of the population. A strong market for mobile technology drove the development of smaller and cheaper phones until there was one to suit every pocket. It was teenagers—always cultural innovators—who developed extraordinary dexterity and OMG!
No one would have been more surprised at this development than the companies who first invested in cellular mobile phone networks, thinking they might have a market among wealthy businesspeople keen to acquire the latest gadget. Countries besides the UK and USA also developed their own networks, and calls stopped at their borders. Taking their lead from the Nordic countries, which had cooperated to develop networks, a group of European government and industry technocrats came together in to work towards a common standard.
In European leaders met in Bonn to sign the agreement that would allow mobile phone users to roam from one country to another, hopping from network to network. The common standard agreed in was called GSM. They would initially use a single radio frequency band, MHz, across Europe, ensuring that users could pick up a signal wherever they were.
They would include provision for SMS short message service, or texting , and would have increased security features.
Nine out of ten people in the world today are now within reach of a terrestrial GSM network. We see continued GSM business opportunities in Single RAN Advanced capable hardware modernizations, high-quality voice capacity upgrades as well as smart device, machine-to-machine and high definition voice enhancements.
Of course, none of this could have been possible without the pioneering work by so many bright minds in the industry over the last twenty years. That work continues today and it is terrific to see GSM continuing to evolve and renew in many exciting ways. Nokia Siemens Networks technology directly supports 2. Nokia introduced its first digital handheld GSM phone, the Nokia , in GSM digitizes and compresses data, then sends it down through a channel with two other streams of user data, each in its own timeslot.
