WiFi is like an invisible net, scattered in people's dense places. At home, on roads, restaurants, playgrounds, cafes, libraries, etc., WiFi is the most widespread untrusted signal; A total of 9.98 billion WiFi devices have been sold worldwide, and about 4.5 billion WiFi products are currently in use. At the same time, WiFi devices are expected to grow at an annual rate of 10% in the next five years, along with WIFI signal amplifiers, 5.8G signal amplifiers, variable frequency low frequency signal amplifiers, etc. will also be widely used.
Why do many people use WiFi in the smart home world but have a low sense of existence?
Technology cannot be "hard wounds" with one shot. WiFi is not a big problem as a connection to the Internet, but for smart homes there are at least three points of great power.
1, security. Here, not directly to say, WiFi security encryption technology how vulnerable, also no longer mention foreign home devices were "destroyed" examples, just want to let everyone think about, without knowing that home WiFi traffic for no reason by strangers to use, you can understand that WiFi is not a difficult thing. And if the smart home is attacked, it may not be as simple as less traffic.
2, health. Wireless technology can have some radiation, but compared to other technologies, WiFi is often the most health-threatening, even if we use it regularly and most of the time without discomfort. Is it harmful? The World Health Organization has pointed out that there is no evidence that cell phone radiation can have a negative impact, in general, a 20-minute phone call, the body absorbs more radiation than the use of a wireless router for a year.
But some industry insiders have pointed out that if WiFi is not used correctly, it can cause harm to the human body. The amount of radiation received by the human body is related to frequency and distance, the higher the frequency, the greater the damage, the greater the distance, the smaller the harm. Therefore, if the use of high power WiFi devices, closer to the device, autoimmunity appears to be low, because of WiFi dizziness, insomnia and other physical discomfort is entirely possible.
3, "life." Typically, a smart home is a system involving multiple devices, while WiFi networks carry a limited number of devices. According to reports, "WiFi network ingress ability is relatively low, the actual size of the current WiFi network generally does not exceed 16 devices, and in the actual home environment, the number of switches, lighting, home appliances alone is far more than 16." This clearly does not fit in with the development of smart home.
