Unconsciously, it has been nearly 50 years since mobile phones entered people's lives. Nowadays, with the improvement of people's living standards and the rapid development of technology, mobile phones have developed from the original luxury consumer goods to the very popular consumer electronic products. Looking back at the development process of mobile phones, there have been huge changes in both shape and function. The development of mobile phones has also undergone changes again and again. Before talking about the development of mobile phones, let's first understand the concept of mobile communication systems that are inseparable from mobile phones.


1G: The first-generation mobile communication system is an analog cellular mobile communication. The characteristics of mobility and cellular networking start from the first-generation mobile communication, but 1G is an analog communication with poor anti-interference performance. At the same time, the simple use of FDMA technology makes Frequency reuse and system capacity are not high.

2G: The second generation of mobile communication technology adds more multiple access technologies. At the same time, 2G is digital communication, so the anti-interference ability is greatly enhanced. The second generation of mobile communication can be said to lay the foundation for the next 3G and 4G.

3G: refers to the third generation of mobile communication technology. Generally speaking, it refers to a new generation mobile communication system that combines wireless communication with multimedia communication such as the Internet. It can handle various media forms such as images, music, and video streams, and provide various information services including web browsing, teleconferencing, and e-commerce.

4G: refers to the abbreviation of the fourth generation of mobile communication and its technology, which can transmit high-quality video images and technical products with image transmission quality comparable to high-definition television.

5G: refers to the fifth-generation mobile communication technology, which is a new generation of broadband mobile communication technology with high speed, low latency and large connection characteristics, and is the network infrastructure that realizes the interconnection of human, machine and things.



Let's briefly talk about the development process of mobile phones over the years.

On April 3, 1973, Martin Cooper, a former Motorola executive, made the first ever mobile phone call. 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 Motorola DynaTAC 8000x, the world's first commercial mobile phone.

The first generation of mobile communication era is the world of Motorola.

The quality of the analog mobile phone system is completely comparable to that of a landline phone, and both parties on the call can clearly hear each other's voices. However, compared with digital communication, analog mobile communication has poor security performance, can only implement voice services, and cannot provide various value-added services; the network coverage is small and the roaming function is poor.



The second generation of mobile communication is the GSM era. After the GSM era, major mobile phone manufacturers were optimistic about this new business opportunity and scrambled to expand their market share. Motorola refused to give up the existing site and locked up the analog network, so that it failed to adjust its market strategy in time. Its dominance quickly declined. At the same time, manufacturers such as Nokia and Ericsson came to the fore and became the trend of the three countries.



In 2007, after years of development, mobile phones have basically taken shape, and various manufacturers have basically determined their own styles. Before the iPhone revolutionized, everyone was racing in their respective markets. At the same time, everyone is compatible with each other. The successful experience of one brand is immediately copied to another brand. If you are ultra-thin, I will be ultra-thin, if you are smart, I will be smart, and 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, the 3.5-memory true color capacitive screen, and the iPhone's operating system, which is 5 years ahead of its competitors in the market, bring a revolutionary experience. Its appearance has subverted the entire mobile phone market, and the mobile phone has entered a new era.

In 2007, Apple entered the mobile phone market. In the high-end market, the impact on Nokia, Motorola, Sony, and Ericsson was obvious. Taiwan's ODM industry was affected the most. The industrial chain began to undergo differentiation and transformation. Company transfer.

5G mobile phones are developing rapidly, technology is more and more developed, and the pace of the times is getting faster and faster. The early mobile phones only had the function of making calls, and then gradually added functions such as text messages, multimedia messages, photography, and games, and the screen changed from black and white to color. However, a few years later, when the mobile phone is connected to the Internet, the whole world has undergone an unexpected major change. The mobile phone has transformed into a smart phone, and APP applications have made people's lives more colorful. In the future, under the escort of 5G network, 5G mobile phones will enter the era of the Internet of Everything. With a mobile phone in hand, shopping, consumption, catering, education, and telemedicine can all be handled. The mobile phone is no longer a tool for communication, it is connected with human desires and technology, and its changes and value are even more amazing.
