WiFi
WiFi-based smart home products are the most common, because WiFi itself is popular. For users, the WiFi-based smart home combination is the most convenient and the purchase of equipment can be directly networked.
The Chinese name for WiFi is called wireless high fidelity. Prior to the emergence of smart home products with a sense of mastery and control over the past two years, WiFi was mainly used for the transmission of big data streams (such as TV boxes, speakers) - so its advantage is its high transmission speed, with the disadvantages of both cost and power consumption. Relatively high.
In addition, because the WiFi smart home requires always online, in the smart home networking WiFi load on ordinary routers is relatively high, according to a few friends in the industry to give the data of an ordinary home routing load is about 8-10 devices, after the stability There will be changes in sex.
Domestic WiFi smart home products have Broadlink, small K sockets and so on.
Zigbee 
Zigbee's products seem to be relatively rare, because both WiFi and Bluetooth are rolled out with the popularity of mobile devices. Zigbee has been more oriented toward industrial and engineering applications. Zigbee is characterized by low power consumption, low cost, large network capacity, and low transmission rate.
In general, Zigbee is rarely used for data stream transmission, but it is very suitable for the delivery of fragmented information such as smart home sensing and control.
Zigbee's networking mode is a WiFi connection to a mobile device, and then a WiFi-to-Zigbee hub controls all Zigbee products. Ordinary households did not have Zigbee infrastructure in the past, so the difficulty in promoting such smart home products is to push the Zigbee hub out. Fortunately Zigbee hardware is the cheapest among the three.
Bluetooth
Bluetooth is a point-to-point communication method whose main purpose is to serve mobile devices. Bluetooth's power consumption and cost are between the first two, but the transmission distance is the shortest. Depends on mobile devices and short distance transmission also determines the Bluetooth products will provide some of the more personal experience, such as Bluetooth anti-lost device, Bluetooth speakers, smart scales.
The positioning of the three types of communication technologies, WiFi is the infrastructure, Zigbee acts as a means of connection between devices (M2M), Bluetooth services mobile devices. WiFi and Bluetooth now have a lot of terminal support, but they are not the best solution for home networking. For Zigbee, the existing problem is finding a reasonable way to lay the terminal.
