In the 90s the use of mobile telephony began to become popular, and it is worth mentioning that at that time, its cost was high so very few people could use it; a fact that also turned it into an object of desire. And although this story with mobile telephony began many years before, its evolution has been constant until today in which, if we do not see a G on our screen next to the signal strength, we feel lost, but,
What does the G on our phone really mean?
“G” comes from the word Generation and started in 1970 when mobile data technology appeared; this allowed calls to be dialed with phones that did not have a cable connected to them, something totally revolutionary and innovative for its time. Its service only accepted voice, and its transmission speed ranged from 1kbps to 2.4 kbps. A curious fact, these calls had no security since they were reproduced, from radio towers.
An increasingly rapid and extensive advance
The 90s arrived, and with them, an immense advance of technology as the popularization of cell phones and telephony caused mobile networks to be overcome; here appears our new friend, the GSM.
Its letters stand for “Global System for Mobile Communications”, this standard allowed data transfer at a higher speed (14 kbps to 64 kbps), opening the door to fax transmission, SMS, roaming, image exchange, and the possibility of surfing the Internet.
Hear that boom? It’s the telephony explosion.
Science Fiction movies were those places where we saw video calls through a cell phone, and it seemed like something impossible to achieve until, in 2003, 3G, mobile internet, arrived in the world of telephony.
With this advance, speeds of up to 2mbps per second were reached, which allowed audio, images, voice, and video applications in real-time by this time in history, the first smartphones began to appear.
With the arrival of 4G connections, speeds of up to 100mbps per second were reached thanks in part to the constant improvement of antennas and their coverage capacity; technologically, this allowed us to access a greater amount of content faster and almost anywhere we were: we can watch series or movies, listen to music or watch any sporting event in real-time with a quality really similar to that of TVs.
This technological boom meant advances of all kinds within communications since, as we see it today, the limitations of uses with mobile data or the internet are almost null, inside or outside the house.
You can download video games in large amounts of data within a short period of time, and talk to anyone anywhere in the world using data and video transmission, soon we will be able to be part of life in virtual reality with the metaverse and of course, use more help from artificial intelligence.
As you can see, the advance in telecommunications is not only a breakthrough for technology, it arrives with improvements to our daily lives and greater connectivity with the world around us, so the next time you do a live broadcast from your cell phone, remember to thank the G that appears on your screen because, without it, none of it would work as you know it now.
