Subscriber growth and revenue generation have been hampered by the limits of the technology. Because only three radio channels available was only three customers in a certain city who could make phone calls at the same time. With GSM 2 g was larger and people began to use mobile phones in their daily lives, it has become clear that the increased demand for data (e.g. access to Internet research). In addition, alerts services for fixed broadband, which showed that there is a growing demand for greater speed. 2 was almost the task, while the industry has started to work on the next generation of technology, known as 3 g. The main technological difference that 3 g technology is different from 2 g technology is the use of. Enable automatic use and voice complete and data communications Mobiltelefonen.In of engineers to the United States from Bell Labs in a system that calls for mobile users and the place of cars, first after the inauguration of the mobile service, on June 17, 1946, in St. Louis, Missouri.

Existence of some users had radically (advanced for the day) full-duplex Briefcase telephones at the end of the CCR, industry associations worked to allow multiple decoder with more than one of the report of the common formats of a technical standard that would have allowed some users of mobile and mobile (600/1500, 2805 and reach). Manuel has often been a fallback for RCC balls. However in the USSR the decision taken by the development of the system was struck the Altai car phone (zhizn Science magazine, 8 and 10, 1957, 1958, Technika-Molodezhi magazine, 2, 1959, za Rulem magazine 12, 1957, revista technology Yunyi 7, 1957, 1958, 2 and 9, 1996, Orlovka Pravda newspaper, July 12, 1961) Bulgarian company. 1965 Pochin presents in Cell Phone Buying Process the automatic Inforga-65 mobile Moscow international exhibition in conjunction with a base station.
