Antonio Meuzzi invented the “Telettrofono” telephone in 1848.
Philipp Reis invented the “Thelephon” telephone in 1861.
Alexander Graham Bell invented the “Bell Phone” in 1877.
Radiotelephones have been used for a long time since the 20th century, first as various experiments and later especially in World War II.
The history of mobile phones
Radiotelephones have been used for a long time since the 20th century, first as various experiments and later especially in World War II.
History the first mobile phones met car trunk and weighed many tens of pounds. For the average citizen, mobile phones became more widely available from the 1950s onwards. Handheld cell phones have been available since 1973.
In 1960, the world's first partially automated machine was opened in Sweden car radio system MTA. Car radios were still based on pipeline radio technology and relays. The phone's car hardware weighed a total of 40 kilograms at the time.
In 1962, a modernized version of MTB based on transistor technology was introduced.
The MTD version released in 1971 was already a commercial success. The handheld car radio (ARP) network was opened in Finland in 1971. It also gained great popularity.

Have you seen such old phones?
The Motorola DynaTAC went on sale in 1984.
Martin Cooper invented the first practical handheld phone in 1973.
The MTD version released in 1971 was already a commercial success. In Finland, a manual was opened Car radio (ARP) network in 1971. It also gained great popularity.
Motorola researcher and director Martin Cooperia considered the first as a developer of a practical handheld mobile phone.
Motorola and Bell Labs had been in a tough race to develop a mobile phone. Finally, on April 3, 1973, Cooper called with his heavy but handheld cell phone, which then became a product called Motorola DynaTAC, to his rival, Joel S. Engel of Bell Labs. DynaTAC was not a commercial product at that time. It did not appear on the market until 1984.
Finland's first portable mobile phone was Saloran SRP-24.
It was released in 1974. The device operated on an ARP network, weighed five pounds, and lasted about a day. Thanks to the device, Salora became the market leader in mobile phones in Finland.
Motorola was a pioneer in mobile phone technology, making a major contribution to the development of mobile phones with its Motorola MicroTAC, which had a cover to protect the keyboard, and in particular, its 1996 Motorola StarTAC, the first mobile phone to gain popularity.
The world's first automated cellular network was opened in Japan in 1979. NTT had built a first-generation (1G) cellular network in the Tokyo metropolitan area. In five years, the network expanded to cover the entire population of Japan.
In 1981, a similar Nordic NMT network was opened in Norway, Sweden, Finland and Denmark. However, Saudi Arabia had already had time to open its own NMT-450 network for commercial use a month before the Nordic countries.
NMT was the first mobile phone network in the world to use the phone abroad, ie roaming. The first 1G network in the United States was opened in Chicago in 1983. Several other countries opened their own cellular networks in the 1980s, including the United Kingdom, Mexico, and Canada.
Modern cellular networks
The first second-generation (2G) network, still in use, was opened for commercial use in 1991 by Finnish Radiolinja, which has since merged into Elisa. At that time, digital GSM mobile networks were introduced. In Finland, it also marked the beginning of competition in the mobile phone market, as it had previously been dominated by them alone Tele on their NMT450 and NMT-900 networks.
In 2001, the Japanese NTT launched the first commercial third-generation (3G) cellular network based on the WCDMA standard.
Today, the basic features of 3G networks are high-speed data connections implemented with the HSSPA and HSUPA technologies of the HSPA family. These are variously called 3.5G, 3G + and turbo 3G. Data transfer speeds have already been accelerated by LTE technology, also known as 3.9G.
