What is the difference between Zigbee and Wifi?

1. The transmission speed is different. The transmission speed of ZigBee is not high (<: 25Kbps), but the power consumption is very low, and the battery power supply can generally be used for more than 3 months; WiFi, which is often referred to as wireless local area network, has high speed (11Mbps) and high power consumption, and is generally connected to an external power supply; 2. Different applications. ZigBee is used in low-speed and low-power occasions, such as wireless sensor networks, and is suitable for industrial control, environmental monitoring, smart home control and other fields. WiFi is generally a wireless network technology (covering about 1 meters) used to cover a certain range (such as a building). The form of expression is our common wireless router. A wireless router is arranged in a building, and the laptops (with wireless network cards) in the building can basically access the Internet wirelessly. 3. Market Status As a new technology, ZigBee has been developing and popularizing at a high speed since the first version of the standard was released in 24. At present, due to the reasons of cost and reliability, it has not been widely promoted; WiFi has a lot of mature technologies and many applications. Generally speaking, there is a big difference between them, their market positioning is different, and the competition between them is not great. It's just that they have * * * similarities in technology, and their mutual interference is still relatively large, especially the interference of WiFi on ZigBee.

at present, the advantage of WIFI is that it is widely used and has spread to thousands of households. The advantages of ZigBee are low power consumption and ad hoc network. However, these two technologies also have their own shortcomings, and none of them can fully meet all the requirements of smart home.
