How Can We Live our Lives Without Mobile Phones?

By: Maria Literral

Since the 1980s, the mobile phone has been transformed from an expensive item used by businessmen to a truly popular communications device that's used by much of the population. in actual fact, these days, mobile phones outnumber landline telephones in numerous countries.

Forget 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 phone call while he was walking the streets of new york city and did so via the first Motorola DynaTAC prototype in front of journalists. motorola has a rich history of making radios for vehicles, particularly two-way radios for cabs and police cars. however, recognisable mobile telephones have existed in some form since the 1950s at least.

The earliest mobile phones were called first generation phones, also known as 1-g. The 1g era lasted from the late 1970s through to the 1980s. these items were the first genuine mobile phones, although they were then named cellular mobile radiophones, & were based on analogue signals. the analogue signal would be the main difference between these first generation mobile phones & their second generation cousins, which was released a few years later.

Second generation (2g) mobile phones initially appeared in the nineties. Unlike 1g phones that were analog, 2g phones use digital technology to provide voice services and for sms text messaging and wap.

Some of the advantages of 2-g phones are that they use less strong radio signals, which require less battery power. This means that phones last longer between charges, so batteries - and therefore the telephones themselves - can be made littler. as well as this, 2-g phones offer more privacy. Indeed, digital cellular calls are a lot harder to eaves drop on than 1g telephone calls.

The term 2.5G is used to describe the phone technology that is post 2g, but not quite 3g. However, while the terms 2g and 3g are officially defined, the term 2.5G is not. in fact, this term was invented for marketing reasons only.

3-g is the word applied to the third generation of mobile telephone standards and technology. 3g follows 2g mobile telephone technology.

The invention of 3-g technologies allow network operators including Vodafone give their users a wider range of more advanced services. These include video callsand broadband internet.

Although 3-g was successfully introduced all over the world, some complaints have been made by both 3-g providers and users, including expensive phones. as well as this, there's numerous differences in the terms of licencing.

We hope our article has given you more information on the mobile phone's history. As you've probably realised, the mobile telephone has come a long way & will probably continue to progress further still.

4g technology will certainly give the mobile phone a new lease of life, promising live streaming of radio and tv shows & a whole lot more besides. For mobile phones, it is clear that the sky is the limit.
