What wireless modules can be used in smart home?

Domestic wireless smart home technologies include WIFI/ Bluetooth /RF, etc. Let's start with these three wireless technologies.

1, WIFI, WIFI is the most widely used wireless communication technology at present, the transmission distance is 100-300M, the speed can reach 300Mbps, and the power consumption is 10-50mA.

2.Zigbee, with transmission distance of 50-300M, speed of 250kbps and power consumption of 5mA, is characterized by self-organization, and the maximum number of network nodes can reach 65,000.

3. Bluetooth, the transmission distance is 2-30M, the speed is 1Mbps, and the power consumption is between zigbee and WIFI.

Compared with Wi-Fi and Bluetooth, ZigBee is an international wireless communication technology. Each network port can access more than 65,000 ports at most, which is suitable for home, industry, agriculture and other fields, while Bluetooth and Wi-Fi can only access 10 ports, which obviously cannot meet the needs of families. ZigBee also has the advantages of low power consumption and low cost. In low-power standby mode, two ordinary No.5 dry batteries can be used for more than 6 months. However, the technical and ecological construction of Xiaomi, Haier and Ou Ruibo in Zigbee smart home is still acceptable in China at present, and the stability and functionality of the products are also remarkable.
