Who invented the telephone The invention of the telephone, as we know it, that is, of the electric model, is still disputed today, with at least five competitors for this title. However, the first to obtain a patent for the electric telephone was Alexander Graham Bell in 1876. He invented the device in his spare time, outside of working hours at the University of Boston, where he teaches vocal physiology. His phone had a separate microphone and receiver, and the signal was poor.
Following tests in the following years, Bell was able to establish a long-distance connection between Chicago and New York in 1892 (October 18) on the first invented telephone . The news immediately spread across America, reaching the world.
The inventor of the telephone continued to improve the patent and sound quality, over time its design underwent numerous changes, from the mounting of the microphone and the receiver on the same side to the addition of the dial for dialing. However, not everyone could afford at least one disc phone, even in relatively recent times.
However, the history of the phone continued to evolve over the next 100 years, with the removal of the disc that was replaced with buttons, and the wire disappeared, too, allowing the user to move freely. However, the landline phone was initially bought only by the rich, because not everyone could afford such an object.
The first mobile phone, or rather the first patent for one, was filed in 1908 in Kentucky, USA, two years later by the Swede Lars Magnus Ericcson putting into practice this cordless phone concept that he installed in his car. Using a two-wire antenna, the connection is made with the national telephone network, from his car.
By the 1930s, disc phones had become a commodity that many could afford, and the cell phone was still a dream come true for those with limited possibilities. The Soviets I Zaharchenko and G Shapiro managed to get good results after the test with a phone mounted in a car that could connect to the local telephone network in 1946.
The concept of cellular telephony was born in the United States in 1947, when call efficiency was improved by adding cellular areas and relays, the invention belonging to researchers at Bell Laboratories.
The first portable phone in the world was created in Russia, by the Soviet engineer Leonid Kuprianovich, in 1957, it was equipped with batteries with a lifespan of up to 30 hours and a disk for dialing numbers, communication with the base station. .
Who invented the mobile phone The first mobile phone in the world, as we know it, was produced in the USA, in 1973, Motorola being the ones who enjoyed this innovation. Martin Cooper was the first to make an appeal in this way, attributing this invention to him, calling his rival Joen Engel, from Bell Labs, in a news that went around the world and remained in the history of the mobile phone forever.
The evolution of mobile phones After several years of discoveries and innovations, the Motorola DynaTAC 8000 X was launched on the market (in 1983), one of the first mobile phones for commercial use. It was not the lightest device, weighing no less than a kilogram. A year later, the first mobile phone that could make calls from one cell area to another was launched by Bell Labs.
The history of the mobile phone continues with substantial developments in terms of size and cellular networks, in the 1990s developing the second generation (2G) of mobile phones that used GSM technology. Among the new services available in the evolution of the phone were the possibility of sending SMS messages, which was done for the first time in Finland in 1993, the possibility of downloading multimedia files such as ringtones (1998) or commercial payments made by phone or internet connection (1999 in Japan) .
The Finnish company Nokia led the market in that decade, selling many models of old mobile phones today, such as the Nokia 1011, and the first smartphone, the Nokia 9000 Communicator, which was also the first business model.
The first touchscreen phone appeared in 2002, being the Sony Ericcson P800, two years before the Siemens competitor launching the first GPRS model, where data packets could be sent between two devices equipped with the same technologies.
In the decade 2000 – 2010 mobile technology developed a lot, appearing devices equipped with color screens, cameras or memory cards, PDAs (personal digital assistant) and increasingly thin and better equipped models were created.
Other manufacturers have appeared on the market, such as Samsung, Huawei, LG, being developed specialized operating systems, in this case Android and iOS, BlackBerry and Windows Phone or the late Symbian for Nokia.
The first iPhone was launched in 2007, being received with hysteria by Americans and less enthusiastically by the rest of the world, given the costs and lack of vital functions. However, following the launch of new models, year after year, Apple has managed to influence a market segment that it still holds today.
The first Android mobile phone launched on the market appeared a year later, in 2008, the model being HTC Dream.
The history of the phone is a rich, complicated one and based on the continuous desire for innovation, this industry continuing to grow, bringing the whole virtual world to the fingertips of the user.
In 2020, Huawei is the largest seller of smartphones in the world, with Samsung in second place. About 1.6 billion such devices are bought annually, with an estimated 50% of the world's population currently owning a smartphone. What does the future hold for us? We can only wait and stay up to date with the directions in which these innovations are heading.
