These days, everybody has a mobile phone. Whether they're on a pay and go tariff or a contract, the mobile telephone has become essential for various people. this article will be looking at the history of the mobile phone - and its future - in order to learn more about the now-essential telecommunications device.
Forget all about alexander graeme bell. On 3 april 1973, dr martin cooper, who was a motorola employee, called one of his rival Joel Engel, who was head of research at AT&T's Bell Labs. dr Martin made the call while he was walking the streets of new york & did so via the first Motorola DynaTAC prototype in front of journalists. motorola has a long history of making radios for vehicles, especially two-way radios for cabs & police cars. although, recognisable mobile phones have existed since the fifties at least.
The first mobile phones are now called first generation (1g) mobile telephones.
The first hand held mobile phone to be released onto the us market was the Motorola DynaTAC 8000X in 1983. mobile phones began to become popular in the eighties with the introduction of cellphones that were based on cellular networks. mobile phones were originally quite a bit larger than current ones, & they were first made for installation in vehicles only, which is why they were called the car phone. these chunky units were later transformed for use as portable phones the size of a briefcase & the rest is history.
Second generation, also known as 2-g, mobile phones were introduced in the 1990s. 2-g phone systems were different because of their use of digital circuit transmission & the introduction of advanced & quick phone to network signalling.
The birth of 2-g systems saw phones move from big 1-g phones to teeny hand-held devices, which were far more moveable. this change was made possible through technological developments such as more advanced batteries & energy saving electronics.
The second generation mobile phones had severaladvantages over 1-g devices. These included sms text messaging, which became possible on gsm networks initially & eventually on all digital networks. the very earliest machine-sent sms message was sent in 1991 in the uk. the very earliest person-to-person sms text message was sent in finland in 1993. sms soon became the communication method of choice & the public now prefer sending messages to placing voice calls.
3g is the word given to the third generation of mobile telephone standards and technology. 3g follows 2-g mobile telephone technology.
The invention of 3g technologies allow network operators including Vodafone offer their users a larger range of more advanced services. These include video callsand broadband wireless internet.
Aalthough 3g was successfully introduced throughout the world, some complaints have been made by both 3g providers and users, which contain expensive telephones. in addition to this, there are numerous differences in the terms of licencing.
We hope our article has told you more about the mobile phone's history. As you've probably guessed, the mobile telephone's come a really long way and will continue to progress even further.
4g technology will certainly give mobile phones a new lease of life, potentially offering the live streaming of radio & tv shows & much more. For the mobile phone, it appears that the sky is the limit. |
