Fixed telephone has a history of 140 years since it was invented. Generally speaking, the inventor of the telephone is Bell. But if we want to explore it carefully, we can actually trace it back to the Five Dynasties in China. According to the "One Hundred Years of Telephone" published by the International Telecommunication Union, in 968, China people invented the "bamboo letter", which is considered as the embryonic form of the telephone and fully embodies the wisdom of the ancestors of the Chinese nation. But when it comes to the development of modern telecommunications technology, we should also look at Europe.
Before Bell, people in Europe were already doing this research. Bell applied for a telephone patent in the US Patent Office on February 1876. However, as early as 1854, the Frenchman Boussard had this idea. Is to connect two pieces of metal with wires. When one side makes a sound, the vibration of the metal sheet becomes electricity and is transmitted to the other side. This knowledge, mentioned in middle school physics today, was a great discovery at that time, which directly contributed to the birth of the telephone.
After the Opium War, while plundering wealth, the West also brought modern postal services and communications, and telephones were introduced to China. After the founding of New China, communication began to develop and recover. After the reform and opening up, the infrastructure of telecommunications facilities has been accelerated, and fixed telephones have been rapidly popularized. In March 2003, the number of fixed telephone users reached 225.626 million, and by 2006, the number of fixed telephone installations reached its peak.
Since then, smart phones have become popular, and human beings have entered the era of mobile communication, and mobile phones have gradually replaced landlines. Since the peak in 2006, the number of fixed telephone installations has been declining. Whether in China, the United States or other countries, landline users are losing.
According to the comprehensive data of the three major operators, the number of mobile users in China increased by 165 1000 from February 438 to June 2065, reaching a total of 849 million. In this context, the fixed-line users of China Unicom decreased by 6,543,800+0,690 in February last year, with a total of only 66.649 million. China Telecom's fixed-line subscribers decreased by 690,000 in February last year and by 7.46 million in the whole year, totaling 654.38+26.86 million.
Fixed line will not be eliminated! Because the advantages of fixed telephones are fixed, just as the advantages of mobile phones are mobile. 1. Some phones need to be fixed in a certain location. For example, the contact number of government agencies needs to be answered by many people. At this time, its immobility becomes an advantage, and when it can move easily, it becomes a disaster. 2. In addition to positioning function, wired telephone is more reliable, can provide better and more stable service, and has advantages. 3. The value of wired telephone to individual users is disappearing, but its function to enterprise users and government users has not disappeared, and it will continue to evolve and develop.
The meanings of mobile phone and telephone are different: mobile phone: it represents an unstable and personal way of moving; Telephone: represents a fixed, relatively stable and open way. Also, fewer fixed-line numbers are easier to remember and more professional.
It is especially necessary for the elderly to be at home, mainly because they are not afraid of power failure and it is convenient for the elderly to make phone calls. Home fixed telephone is mainly for the elderly, although the utilization rate is not high, but the map is convenient to answer. But the plane fare is amazing. More than 20 yuan a month, although not much, but only a few times a month to answer the phone. So people who don't live with the elderly don't need fixed telephones. It can be said that the main reason is arbitrary charges.
