Wi-Fi pseudo-intelligent or out of favor smart home who will take over

Xiaomi smart family suit will be officially opened on June 18th. The traditional Wi-Fi pseudo-intelligence in smart homes will fall out of favor. Can these intelligent linkages be achieved through Wi-Fi? In fact, smart items can be connected through the router at home, but if they form an intelligent system, this will undoubtedly increase the load on the router. Generally, the number of devices that the home router can allow to access is about 15, which will undoubtedly meet the needs of current common applications. .

At the just-concluded Guangzhou Guangya Exhibition, there are few hardware products for smart homes, and most companies have launched their own solutions. It can be said that the current smart home industry has not yet achieved platform unification, but the trend of adopting the ZigBee solution is becoming more and more obvious.

Five reasons for ZigBee's superior position

Power & Battery Life

ZigBee is a low-power transmission technology that allows intelligent hardware to stand up for long periods of time without the need for any wired power supply. An ordinary button battery or alkaline battery can last for more than 6 months or more. Formally based on this advantage, all smart hardware is more flexible to install, without being limited by the socket location.

Transmission distance

Compared with the low-power ZigBee, Wi-Fi does not make much difference in transmission distance. However, in terms of bridging or relay routing, Wi-Fi is more difficult to achieve in a stable manner. Due to the different ways of wireless communication, the transmission distance and stability are different. Wi-Fi is suitable for applications with higher data requirements.

Number of devices connected

Smart sockets, smart bulbs, door magnets, switches, etc., but there are more than 10 small intelligent hardware, not to mention the connection of air conditioners and TVs. But for ZigBee, it's a piece of cake to easily add 30 to 50 devices.

Application field

ZigBee technology has high precision in real-time communication, so it is mostly used in high-end projects in the commercial field. Most people use Wi-Fi to browse pictures, send and receive mail, and especially public Wi-Fi security is even more worrying.

Safety performance

Home Wi-Fi networks can be easily compromised, and security is a tricky issue. Perhaps people's requirements for intelligence are not high, but security ranks first. It is smart to keep secrets. I don't know if you agree with the author. Among the various wireless protocols such as ZigBee, Wi-Fi, and Z-wave, ZigBee has the highest security.
