The first mobile phone
From 1947 to 1973 there were several attempts by the technology companies to show the alleged result. However, Motorola stood out in 1973. From it came the first DynaTAC, the functional prototype that proved wireless communication possible. -
The evolution of the cell phone reaching the shelves
Mobile telephony today is associated with the mobility of the individual, the first cell phones were not so mobile, as they weighed close to 1 kg and were usually installed in cars, almost a fixed telephone for cars.
In addition to the weight, the dimensions of the object were also impressive: almost 30cm in height.
If the prerequisite for having a cell phone was to own a car, you can already imagine that there were a few who could count on such innovation. -
The cell phone as we know it
There is no certain date to point the cell phone as we know it, but the reference here would be the mobility with the individual. It was in the 90's that the devices started to be really mobile, even though they were “bricks”.
Considered the second generation of devices, the evolution of the cell phone could have a well-marked milestone at this point in the timeline. This is where GSM arises, the technology that is even used in cell phones today for networks -
The first SMS
In Finland, the first SMS was sent. In the timeline, this evolution of the cell phone also deserves to be highlighted, because here the functionalities that the device provided started to extrapolate the initial limitations. However, sending an SMS was also not so easy -
The evolution of cell phone screens
Initially, everything was monochromatic. Then came the gray scales. When phones with a blue background appear. Soon after, the evolution of the cell phone took on an air of revolution. 4 thousand colors, 64 thousand colors, 256 thousand colors. In mathematics, you can see the upward scalar curve that the displays followed. And Nokia promoted the first really colorful devices. And today the screens exceed 16 million colors -
Internet 2,5G
In the evolution process of cell phones, the millennium contour marks the advance in transmission speeds and access to information contained on the web. The new concept, then, begins to present something similar to what we currently have, in the 2020s, but with its functionality limitations. -
Mobile Cameras
The first models with a built-in camera were able to capture images that, compared to today's, would be true dinosaurs. Frozen pixels, checkered graphics and colors in a very limited palette.
Ten years ago, for example, in 2010, cameras were pumped with 8MP. In 2020, there are premium models with 108MP in one of the lenses of the photographic set, with the possibility of recording videos with 60 frames per second in addition to the super slow camera. -
The first smartphone
The iPhone literally revolutionized the way of making cell phones, and new companies with better technologies have emerged to cause a new dispute. Here begins the diffusion of what is indispensable today: capacitive screens with full touchscreen, cameras, music, etc.
Since then, cell phones have taken their full form and have been improving more and more and I have no doubt that one day cell phones will be embedded in our wrists or, then, in the brain itself!!!!!!!
