Product Information

West Germany had a network called A-Netz launched in 1952 as the country's first public commercial mobile phone network. In 1972 this was displaced by B-Netz which connected calls automatically. Izmerov, Oleg. "Отечественные Мобильники 50-Х"[Domestic Mobile Phones of the 50's]. Окно В Прошлое (in Russian). While it might be considered extremely unwieldy by modern standards, at the time it was considered revolutionary because mobile telephones were bulky affairs installed in vehicles or in heavy briefcases. The DynaTAC 8000X was 10 inches (25cm) long and weighed 2.5 pounds (1kg). [23] It was truly the first mobile telephone which could connect to the telephone network without the assistance of a mobile operator and could be carried about by the user. In 1991 the first GSM network ( Radiolinja) launched in Finland. In general the frequencies used by 2G systems in Europe were higher than those in the United States, though with some overlap. For example, the 900MHz frequency range was used for both 1G and 2G systems in Europe, so the 1G systems were rapidly closed down to make space for the 2G systems. In the United States, the IS-54 standard was deployed in the same band as AMPS and displaced some of the existing analog channels.
