Discover More About The History Of Mobile Phones

These days, everybody has a mobile phone. Whether they're on a contract or a pay as you go tariff, the mobile telephone has become essential for several people. this article will look at the the mobile phone's history - as well as 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, a motorola employee, placed a call to 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 city & did so through the first Motorola DynaTAC prototype in front of reporters. motorola has a rich history of making radios for vehicles, particularly two-way radios for cabs & police cars. although, recognisable mobile telephones have existed since the fifties at least.

The very first mobile telephones were called first generation telephones, often referred to as 1-g. The 1-g era lasted from the late 1970s through to the 1980s. these items were the first real mobile telephones, although they were then known as cellular mobile radio telephones, & were based on analogue signalling. the use of an analogue signal was the difference between these first generation mobile telephones & their second generation cousins, which came out a few years later.

Second generation, also called 2g, mobile telephones were introduced in the nineties. 2g mobile phone systems were characterised by their use of digital circuit transmission and the introduction of advanced and fast mobile phone to network signals.

The birth of 2g systems saw telephones move from friendly 1g telephones to teeny hand held devices, which were much more moveable. this change was possible through technological improvements including more advanced batteries and energy saving electronics.

The second generation mobile telephones had a number of advantages over 1g devices. These included text messaging, which became possible on gsm networks initially and eventually on most digital networks. the earliest machine-sent sms text message was sent in the uk in 1991. the earliest person-to-person sms message was sent in finland in 1993. sms soon became the communication method of choice and the general public prefer sending text messages to making voice calls.

3g is the term given to the third generation of mobile mobile phone standards & technology. 3g follows 2-g mobile mobile phone technology.

The invention of 3g technologies allow network operators such as Vodafone give their users a bigger range of more advanced services. These include video calls& broadband internet.

Even though 3g was introduced successfully all over the world, complaints have been made by both 3g providers & users, comprising of costly phones. in addition to this, there's numerous differences in the terms of licencing.

Following 3g, we can look forward to the debut of 4g technology, which promises to be the best and most advanced mobile telephone technology to date.

Thanks for perusing our article about the invention of mobile phones. as you probably know, the mobile telephone has come a long way since it was first launched and chances are, it'll be developed further still.
