On April 3, 1973, Martin Cooper, who is considered the inventor of the mobile phone, and was the Vice President of Motorola in New York, had the first conversation in history on the Motorola Dynatake phone, and this conversation was to a competitor, AT&T “AT&T”, which included On the phrase “I am calling you to see if my voice is clearly audible to you or not.”

The length of this phone at the time was 9 inches, and contained 30 electronic circuit boards, and it took 10 hours to charge its battery, and then worked for a period of 35 minutes, as the price of one device was about 4000 dollars.

During the years that followed the invention of the mobile, and the development of its industry, it became a tool that includes multiple means to communicate with anyone in the world, such as voice calls, SMS, free chat programs “Viber, WhatsApp, Twitter..etc.” Nowadays, it is not possible to encounter Someone who does not own at least a mobile phone, especially since the United Nations figures indicate that the number of mobile phones in the world today is about 7 billion.

70 years ago, someone who wanted to talk on a mobile phone had to carry a device weighing more than 12 kilograms, with modest coverage, but the communication process itself was interrupted as soon as he left the wireless signal coverage area, and because of the high costs of this method, mobile communication remained the preserve of politicians and corporate directors.

The first pocket-sized mobile phone was launched on the market in 1989, the “Micro TAC” phone produced by Motorola, and it was the first phone with a cover that could be opened and closed. With this phone, companies began to produce smaller and more accurate mobile phones.

In the summer of 1992, the era of digital mobile communications began, as it became possible to make international phone calls with mobile phones, at the same time that the development of these phones continued, and the Motorola International 3200, the first mobile phone with a data transmission capacity of up to 220 kilobits per second.

The SMS service was introduced in 1994, and in the beginning, this service was dedicated to sending messages about the strength of the wireless signal, or any defect in the network to customers, but these messages, which do not exceed 160 characters each, turned into the most used services after the phone call The same, and many young people have developed special shortcuts for these messages to save.

With the beginnings of 1997, the demand for mobile phones began to increase, especially phones with a cover that can be opened and closed, and those with a cover that can be pulled. popular.

The Nokia 7110 phone, which was produced in 1999, was the first mobile phone with the Wireless Application Protocol “WAP”, which contains applications for using the Internet via mobile phone, and although this application is nothing more than a reduction of the Internet in the form of text, it was a revolutionary step for mobile phones, and this followed Telephone Similar devices that combine telephone, fax, and pager.
