LET'S TAKE A TRIP THROUGH THIS FANTASTIC STORY. The telephone, this object that fascinated the world at the end of the 19th century and today seems so familiar, is the result of many efforts and inventions to ensure that the human voice could be transmitted over long distances. Its history began in the workshop of Charles Williams, located in the city of Boston, where Tomas A. Watson also worked, a person who felt enthusiasm and sympathy for new things, and dedicated himself full time to the invention and improvement of electrical devices. It was in this same workshop that Watson met Alexander Graham Bell, who had studied at Boston University. Bell told Watson these words: “If I could make an electric current vary in intensity in the same way that air varies when a sound is emitted, I could transmit the word telegraphically.” This was the key to the invention that would come to be called the telephone. After many attempts, in 1876, Bell’s dream became possible. Through a device, between one room and another, Watson heard Bell saying: “Mr. Watson, I need you, come.” Thus was born the telephone. The new invention was presented at the Philadelphia Centennial Exposition. Since then, advances in telephony have been great and impactful, leading to what we now call cell phones. In 1973, almost 100 years after the invention of the telephone, Motorola introduced the world to the first mobile phone. This device was designed by Martin Cooper, who made the first call to the competition (Bell Labs), with whom he was competing to create a telephone that did not use wires. This first call was received by Joe Engel, who was not intimidated by the defeat. On the contrary, he perfected the technology and made Bell Labs responsible for the cell phone as it is known worldwide today. Considered the “father” of the cell phone, Cooper innovated by creating a prototype in 1973, a Motorola DynaTAC 8000X model. It became the first cell phone to be sold in the world, which only arrived in stores in 1983. Another interesting fact is that the first device was sold before cell phone plans even existed! Only a few months after its launch did the first plan appear, costing 50 dollars per month. In current values, the plan was equivalent to 127 dollars, approximately R$521.00 per month. With that, we can consider that the price per minute cost R$4.20! That’s a lot of money for a cell phone plan, isn’t it? 1990 - Motorola PT-550: the first cell phone in Brazil! The first cell phone in Brazil was a Motorola PT-550, a device that arrived with the mobile phone network in Rio de Janeiro in 1990. Its screen only showed 7 digits and system alerts. In addition, it was still quite heavy, a “brick”, as older cell phones were nicknamed. Learn about the features of the first cell phone in Brazil: 348 grams; 22 cm long; Longer-lasting battery, with 15 hours of standby time. It was in the 1990s that the cell phone technology we know today began to develop. It was at this time that the first text messages and high-tech connection networks such as IDEN, CDMA, GSM, which lasted until the turn of the millennium, appeared. 1992 - The first SMS The evolution of the cell phone also includes the first text message in history: “Merry Christmas”. It was sent on December 3, 1992 by engineer Neil Papworth, who was 22 years old at the time. He worked at Vodafone, a UK operator. The message was typed on a computer and was part of a test. It was sent to Richard Jarvis, director of Vodafone, who received the text on an Orbitel 901 model, one of the first cell phones in the world to have GSM network integration. After this feat, it took a long time for SMS to become popular. At first, text messages were exclusive to engineers and enthusiasts. 1994 - IBM Simon: the arrival of the touch screen You thought it would be a Samsung or iPhone, right? However, the IBM Simon model was the first touch screen cell phone! By default, it was possible to access contact lists, calendars, clocks, notepads, etc. It's incredible to think that the first steps of the "touch era" began exactly 25 years ago! 1996 - Motorola StarTAC On the other hand, the first flip cell phone (those foldable models, you know?) was the Motorola StarTAC! It was inspired by the communicator that the crew of the Star Trek spaceship used in the American series. We end with these questions: How do you imagine a cell phone with a century of history? How could it (cell phone) be? What technologies could emerge? Philosophy in Action channel – subscribe and help the channel bring you more knowledge.
