Mobile phones : History

Mobile phones History

Since the mid-1990s, cell phones (or cell phones / cell phones) are becoming more and more important in our daily lives. Before, phones did not do much more than make calls and send messages. Today’s smartphones are like computers that are smaller than phones. I often hear people at work talking about the latest apps they have downloaded on their iPhone or Android phone. And while many of the apps are useful, many are not. For most of us, at least our time is often short, we have a desire to keep downloading new apps to keep ourselves entertained.

The size of the handsets

We’ve all seen pictures of phones owned by the late 80s and laughed at how big they were. It’s hard to believe that they were ‘portable’ phones at all. Martin Cooper, who led the first mobile phone manufacturer (Motorola DynaTAC – 1973). Once remarked that although the battery life of the phone was only 20 minutes, that was not a problem because you would not have a long-lasting handset because of its weight (2.2 – 1 kg).
During the 1990s, the size of handsets gradually decreased until the early 2000s they were so small that buttons, for most people, could be easily used. I had a phone like this and I finally had to give it to my son because my fingers were too big, and I found it very difficult to avoid pressing two letters on the keypad at the same time.

Some of the first Pioneers

I have already mentioned Martin Cooper, who led the team that built the first cell phone in 1973, but there have been many other people who have played an important role in the history of cell / cell phone. Going back to people like Samuel Morse and Michael Faraday who initially excelled in fields such as telegraphy and electromagnetism, they passed on to Alexander Graham Bell and Guglielmo Marconi who played a key role in telephone programming and radio broadcasting, respectively.

Mobile phone generations

The history of mobile phone history is often divided into generations (first, second, third and so on) to mark a major change in skills as technology advanced.

First generation (1G) cell phones

The first commercially operated network (1G generation) was launched in Japan in 1979 by NTT in Japan. Within a few years, the network had expanded to cover the entire Japanese population and became the world’s first 1G network.

Second generation (2G) cell phones

In the 1990s, second-line (2G) systems developed. This was mainly using the GSM standard. 2G differs from 1G by using digital transfers instead of analog transfers, as well as fast band-phone-to-network signatures. The rise in the use of mobile phones due to 2G has been exploding and this time around the advent of pay-as-you-go calls.

Third generation (3G) cell phones

In the mid-2000s, the 3G (third generation) telecommunications law was introduced. There were also 3.5G, 3G + or turbo 3G processes.

Fourth generation (4G) cell phones

In 2009, it was clear that 3G networks would be hampered by the growth of advanced bandwidth applications such as media streaming. As a result, the industry began to look at fourth-generation data technology, with the promise of speed up to 10 with existing 3G technology. The first commercially available technology to charge as 4G was the WiMAX standard (offered in the U.S. by Sprint) and the LTE level, offered for the first time in Scandinavia by TeliaSonera.
