The history of mobile phone development: It took 45 years to change the world. On April 3, 1973, former Motorola executive Martin Cooper made the first mobile phone call in history. The phone used by Martin Cooper weighs about 1.13 kilograms and can talk for a total of ten minutes. It is the prototype of the world’s first commercial mobile phone, the Motorola DynaTAC 8000x.
Today, 45 years after the first mobile phone call, almost everyone has a mobile phone. Looking back at the development process of mobile phones, there have been earth-shaking changes in both appearance and function. The development of mobile phones has also gone through changes again and again…
The first generation of mobile communications, referred to as 1G, is owned by Motorola.
The quality of the analog mobile phone system is completely comparable to that of landline phones, and both parties can clearly hear each other’s voices. However, compared with digital communications, analog mobile communications have poorer confidentiality and are easily stolen. They can only provide voice services and cannot provide a variety of value-added services. The network coverage is small and the roaming function is poor.
The second generation of mobile communications, referred to as 2G.
The GSM digital network has strong confidentiality and anti-interference properties, clear sound quality, stable calls, and has the advantages of large capacity, high frequency resource utilization, open interfaces, and powerful functions.
After the GSM era, major mobile phone manufacturers were optimistic about this new business opportunity and rushed to expand their market share. Motorola refused to give up its existing territory and clung to the analog network, so it failed to adjust its market strategy in time. Its dominance declined rapidly. At the same time, manufacturers such as Nokia and Ericsson caught up from behind, forming a three-way alliance.
2007 ushered in a new era of smartphones
In 2007, after years of development, mobile phones have basically taken shape, and each manufacturer has basically determined its own style. Before the revolutionary impact of the iPhone, everyone was racing in their own markets. At the same time, everyone is compatible with each other, and the successful experience of one brand is immediately copied to another brand. If you are ultra-thin, I will also be ultra-thin. If you are smart, I will be smart. If you take pictures, I will take pictures.
After Apple achieved great success in the MP3 market, it reached out to the mobile phone market. The 600MHz arm11 processor, 3.5-inch true color capacitive screen, and iPhone operating system that is 5 years more advanced than competitors on the market bring a revolutionary experience. Its emergence has subverted the entire mobile phone market, and mobile phones have entered a new era.
5G mobile phone
Science and technology are becoming more and more developed, and the pace of time is advancing faster and faster. Early mobile phones only had the function of making calls. Later, they gradually added text messages, multimedia messages, photography, games and other functions, and the screen also changed from black and white to color. However, a few years later, when mobile phones were connected to the Internet, the whole world underwent an unexpected change. Mobile phones transformed into smartphones, and APP applications made people’s lives more colorful. At this time, the mobile phone is no longer a tool for making calls. It is interconnected with human desires and technology, and its changes and value are even more amazing.
