When was the first mobile phone invented?

The first mobile phones where actually two way radios systems using telephone systems to communicate; however, mobile users could not dial in specific numbers and technically are not considered cellular phones. The technology used by the two way radio systems is the basis for all cellular phone technology now in existence. Cell phones are called cell phones due to that fact that each part of the coverage area is split into “cells” of hexagonal shape and the initial idea was developed at Bell Labs in 1947. The proposed structure of the cells had transmission towers that broadcast in three directions into three adjacent cells and were placed on the edges of the cells instead of the center for optimum coverage.

This technology was not further developed as the hardware needed had not been developed; frequencies had not been allocated for use and the technology remained mostly underdeveloped until the 1960s. There were a few instances of direct dialing from a phone as far back as the 1950s but was limited to particular areas and service was rare in most cities. The MTA, Mobile Telephone System A, was released in Sweden in 1956 by the Ericsson Company and was the first independent dialing system introduced to the market. It did have the disadvantage of having a very heavy phone weight of over 80 pounds. At the same time a Russian was developing a “radiophone” that was wearable and had an effective cell range of about 40 miles. In 1970 there was service for the phones in over 30 USSR cities; this was the first year of analog cell phones in the US which was introduced by Motorola.

Also in 1970 was the advent of cell handoffs which allows for different service areas to exchange the phone call between them and was developed by Bell Labs; the modern version of this is called roaming. Soon after in 1971, AT&T petitioned the FCC for the use of cellular phone networks which was finally approved in 1982 after a long and arduous debate. The first commercially and publicly available network of cellular services was released in Finland in 1971 and was called ARP; this network and its protocols is referred to as the 0G generation of cellular technologies. All of these early networks used analog transmissions until 1990 when digital transmissions took over in the cellular arena rushing in the advent of the 2G network protocols and technologies. Prior to the 2G network phones resembled “bricks” and while they could be ported from place to place did not bode well in personal mobile communication.

The 2G network saw a drastic rise in the number of people using cellular phones and networks ushering in the more modern look and size of today’s cellular phones. The first digital networks superseded the 1G analog networks and brought to the public SMS text messaging as well as the ability to retrieve and use media and content from companies such as downloadable ringtones. Due to this rise in the text messaging and downloading as well as an increase in the need for web access and data usage on cellular networks the 3G standard was pursued. The 3G network, which can be accessed using MobilityPass mobile broadband Internet services, was not standardized in technology but one of the requirements of data transmission.
