Why is WiFi abandoned by mainstream smart home enterprises

wifi, as a popular technology, is widely used in consumer electronic products such as, tablets and so on. It is the king way to select suitable experimental machines according to actual needs for efficient utilization. However, why has it been ruthlessly abandoned by mainstream smart home enterprises? In the final analysis, because it can adapt to a variety of experiments, there are two basic reasons: 1. It threatens health and safety. 2. Threaten information security

first, health and safety. As we all know, there are a large number of devices that need to be connected in the family. There are dozens of home appliances, small appliances, lights and switches in the family. If these dozens of devices transmit WiFi signals, it will pose a fatal challenge to family health. At present, many people will turn it off or put it far away from the bed to prevent WiFi from allowing the experiment to measure electromagnetic radiation from related objects by itself. However, if the switches, electrical appliances and other devices in your home have WiFi functions, and the whole family is covered by dozens or even hundreds of times of WiFi signals (the electromagnetic radiation of the WiFi of electrical appliances and switches is far greater than that of portable devices such as tablets), you will have nowhere to escape. You will be surrounded by powerful electromagnetic radiation for years and months, and the impact on health, especially for pregnant women and other people with weak physique, will be more deadly. What is more frightening is that if this technology is popularized on a large scale, the WiFi electromagnetic radiation of your neighbors will be superimposed on your home. In densely populated residential buildings, the radiation will be geometrically amplified, and the health of the residents of the whole building can not be guaranteed at all

as Bill Gates, the former president of Microsoft, who is concerned about human health, said: "a large number of WiFi devices in the family will be a disaster." From the current situation, the global mainstream manufacturers involved in smart home are all far away from WiFi technology. Although the WiFi alliance has done a lot of work in the face of the huge smart home market, WiFi has basically stopped in the experimental stage. Of course, at the present stage, some domestic start-ups have low difficulty in developing WiFi technology. Taking advantage of the low judgment of Chinese consumers on technology, they have launched public opinion tools to continuously amplify and publicize the advantages of WiFi, covering up the harmful effects of large-scale WiFi applications on the human body

secondly, for the information security of WiFi, almost anyone who knows a little about the technology has encountered the security problem of WiFi. Among all wireless technologies, WiFi is the most insecure technology in the world. A simple card rubbing can easily crack it. A "Snoopy" remote control plane flies over your head. As long as your device turns on the WiFi function, Whether it is your tablet or the so-called smart router, all the information will be exposed. The lack of security of Wi Fi has almost become a global public knowledge

the smart home industry is also an industry that pays special attention to security. It can be said that there is no smart home without security. Once a home device is connected through WiFi, it will bring disastrous security risks. Recently, the smart route produced by a famous domestic manufacturer has been broken, and a large number of personal privacy pictures and videos in the hard disk built in the router have been exposed, causing public concern, Although the manufacturer has stepped up media public relations and tried to draw the attention of public opinion from other aspects, technology enthusiasts know that the fundamental problem is the insecurity of WiFi technology. Another influential security incident is that the WiFi home smart socket produced by Belkin company of the United States was broken by hackers, resulting in malicious manipulation of home appliances, which almost led to casualties. Therefore, it is not surprising that WiFi was snubbed by mainstream smart home manufacturers

although many manufacturers have made great efforts, the security of WiFi has not been improved. Insiders said that from the current situation, it is difficult to significantly improve the security of WiFi technology in the foreseeable future. If this technology is applied in areas with high security requirements, we must be very careful

of course, in addition to the above two important weaknesses of WiFi, there are still a series of difficulties to be overcome in the application of wireless technologies such as WiFi in the smart home industry. Such as network size, self-healing ability, etc
