The Application of WI-FI Technology in the Field of Smart Home

No matter what kind of wireless communication technology is composed of smart home network, the premise is to connect the home network, and this happens to be the advantage of WI-FI, most of the world today (mobile or fixed) mostly support WI-FI networking . Although WI-FI is to be implemented in the smart home field, it is actually connected to a network of home devices. It is not a home Internet network, but as a wireless communication technology, it is directly connected to the smart home network and the home Internet. In addition, the conversion of different signals is not required, thereby reducing the difficulty of the development of WI-FI technology in the field of smart home applications.

Compared with ZigBee and other technologies, WI-FI has its own obvious shortcomings, such as relatively high power consumption, relatively low security and anti-jamming capability, and limited network equipment bearing capacity. However, short and swift WI-FI also has its own Advantage. WI-FI's radio waves cover a wide radius of up to 100 nm and can be used in homes, offices, and even entire buildings. WI-FI transmissions without wiring are also very fast and can reach 11 Mbit/s. And social information needs. In addition, relevant professionals said that the amount of radiation of WI-FI devices is negligible and negligible, and does not pose a threat to human health as people fear.

It is worth noting further that although the WI-FI network carries a limited number of home devices, it is also difficult to connect the home devices and achieve the overall intelligence of the home devices. However, the lightweight and lightweight devices also have the advantage of being lightweight. From another perspective, WI-FI happens to possess the flexibility and mobility that other wireless communication technologies do not have. This is also an important reason why many mobile devices have WI-FI capabilities, such as smart phones, tablets, and notebooks. The use of WI-FI by computers and other computers can satisfy individual users' needs for quick messages.

With the rise of "light intelligence" and "micro-intelligence", WI-FI has demonstrated its superiority in smart home applications. Unlike companies such as IOT Sensing that love ZigBee wireless technology, “light smart” home makers prefer to use the family WI-FI to directly connect home devices, for example, putting WI-FI modules into switches and sockets. , As an entrance to a light smart home and a control center, to achieve intelligent control of home equipment. At present, the well-received “light smart” products developed by companies such as Belkin and Torrap in foreign countries are based on WI-FI, and many companies in China have begun to apply WI-FI to smart homes to create local products. "Light Smart" products.
