The Right Tech News You Need to Know

Several manufacturers tested between 1947 and 1973, but the first company to show a working device was Motorola. The name of the device was DynaTAC and was not for sale to the public (it was just a prototype). The first model that was commercially released in the US (some other countries had already received handsets from other brands) was the Motorola DynaTAC 8000x, still in 1983, that is, ten years after the first test.

First Generation Cell Phones

The first generation of cell phones began with not-so-portable phones, so much so that most were designed for installation in cars. Most cell phones weighed an average of 1kg (yes, you read that right) and had absurd dimensions almost 30 inches high. Of course, that was just the beginning, and the tendency was to reduce physical size and increase functions. The price of mobile phones was evidently astronomical, because not everyone had a car to carry these “jokes”.

The second generation was coming

By the early 1990s, manufacturers were ready to launch new handsets of an acceptable size and weight that would not hurt anyone’s spine. The second generation of handsets would not only bring new handsets, but would also adhere to new communication standards. Three major technologies would rule at this time: TDMA, CDMA and GSM. The second generation of mobile telephony lasted until the turn of the millennium (perhaps shortly before or after) and brought several new features, including some that we will mention below.

Speak for what? Send an SMS

An indispensable resource for many people is the text messaging (SMS) service. Few know, but the first text message was sent in 1993 through a Finnish operator. Here in Brazil it took a long time to get “all” this technology, after all, Brazilian operators were still thinking of installing landlines for customers.

Text messaging was no big deal at the time, because it was limited to a few characters and didn’t allow the use of accents or special characters. In addition, it was difficult for you to be able to use the SMS service because you had to be compatible with the technology besides your mobile phone. Cell phones capable of sending text messages were usually equipped with an alphanumeric keypad; after all, the device should have letters as well as numbers.

New services to attract customers

Mobile phones carried rather annoying ringtones, but as technology progressed on carriers and handsets, personalized monophonic and polyphonic ringtones started popping up, a factor that made people spend “rivers” of money just to have the darling anthem.

Team as touch

Time to introduce some colors

No doubt everything was great for consumers, but there was still something missing for the phone to be complete: it was the colors. Devices with monochrome devices simply didn’t convey everything our eyes could perceive. Manufacturers soon introduced grayscale displays that distinguished images. Nevertheless, no one was satisfied, because everything seemed so unreal.

When the first 4,000-color cell phone came out, people thought it was ending the world, because it was incredible technology for such a small device. It was not long before the handsets gained displays of incredible 64,000 colors and soon came up with displays up to 256,000 colors – the images looked real and there was no way to notice the lack of colors. Obviously, evolution has not stopped and today the handsets have 16 million colors, a feature that is critical in high resolution devices.
