History of Mobiles
What if the invention of mobile phones never happened? Well, we wouldn't be able to communicate the way we do now. We have a lot to thank mobile phone history for. Mobile phone history started in 1947 when Bell Labs engineers W. Rae Young and Douglas H. Ring realized that utilizing small hexagonal cells can increase the capacity of mobile phones for traffic at a substantial rate. However, at that time, the technology to do that was still nonexistent.
Mobile Telephone system A (MTA) was the first mobile phone system that was fully automatic. This was created by Ericsson and was released commercially in Sweden during 1956. Mobile phones during this time weighed 40 kg. Thankfully, mobile phones have evolved into smaller versions since then. The Motorola DynaTAC 8000X was the first handheld mobile phone became available to the U.S. market in 1983. These mobile phones became increasingly popular during the 1980s because of the introduction of "cellular" phones which were based in cellular networks that had several base stations located close to each other. Analog transmissions were being used by all mobile phone systems. It was Motorola that introduced the first truly portable handheld phone.
The introduction of mobile phone systems such as IS-136, iDEN, IS-95, and GSM started during the 1990s. It was in the United States that the first digital cellular phone call was made. In 1991, Radiolinja, the first GSM network opened in Finland. Along with the introduction of 2G (2nd generation) systems were the tiny 100-200g handheld phones which instantly became the norm. This change was made possible by improvements in batteries and electronics. The 2G phone systems were characterized by the introduction of fast and advanced phone to network signaling as well as digital circuit switched transmission.
Roughly ten years later, 3G (3rd generation) was launched by NTT DoCoMo in Japan. These mobiles already offer TV and video services, which has made these gadgets even more popular. Quite a number of these phones can also connect to the Internet, which makes them multimedia computers already. It is said that in the future, 4G (4th generation) system will also be introduced. This will pave the way for low cost, high speed data transmission. This will also offer users with a high degree of synchronization and personalization between a wide array of user applications.
With the fast development of technology nowadays, mobile phone history will surely evolve and offer us with new innovations.
