In those principles of mobile telephony, the response of consumers was not entirely satisfactory. This was mainly due to the exaggerated size and weight of the first cell phone equipment and, of course, to the high value of the devices, which were beyond the economic.
Martin cooper in 1973 made the first call from his prototype cell phone.
In 1982, the first cell phones were launched on the market.

Generation 3G
With the advent of the Third Generation, the result of research to increase data transmission and reception capacity, in addition to obtaining a better degree of security in communications, the possibility of connecting to the Internet appeared, with all the advantages that its use provides to users.
The third generation was enough at that time?
Was cellular technology successful at the time?

There is no doubt that the implementation of this new mobile communications standard has revolutionized the way we use the phone, allowing us to do things that were previously impossible to do if we were not near a computer.
Has technology advanced?
This technology will replace the human brain?
