He applied this to “cave radio phones and not directly to cellular telephony, as we know it today. However, the introduction of cells for mobile base stations, invented 1947 by Bell Labs engineers from AT & T, has been further developed by Bell Labs in the 1960s. Radio Phones have a long and varied history back to Reginald Fessenden invention and shore to ship demonstration of radio telephony, by the Second World War with the military use of radio frequencies and telephone links of the public service in the 1950s, while the hand-held cellular devices Are since 1983 . Because of their low costs and the creation of rapid deployment, mobile phone networks have been rapidly throughout the world who are still in the growth of fixed-line telephony.
In 1945, the zero generation (0G) of mobile phones. 0 G mobile phones, such as Mobile Telephone Service, were not officially categorized as mobile phones, because they are not automatically change the frequency of calls channel, it enables the user, from a cell (the base station coverage) to another cell, function called “surrender”.
In 1984, Bell Labs invented as a “call handoff” feature, which allows mobile phone users to number several trips by cells in the same conversation. Motorola is considered the inventor of the first practical handheld mobile phone for use in a vehicle not setting.

With the miniaturization of digital components, mobile phones are increasingly in practice over the years.
Today, video and TV are driving forward to the third generation (3G). And in the future, low cost, high speed data driveforward the fourth generation (4G) as a short-range communications emerges.Service and application ubiquity, with a high degree of personalization and the synchronization between different user equipment, another driver. At the same time, it is likely that the radio access network will be from a centralized to a distributed architecture.
