1、WIFI
2.4G and 5G frequency bands, suitable for short-distance large data transmission, single product directly connected to the cloud;
It is suitable for a single product of intelligent hardware, but not suitable for small-scale intensive terminal applications.
2. BLE Bluetooth
Low power consumption, small data, short-distance point-to-point transmission, focusing on wearable systems, Mesh networking functions are available in version 4.2 and above;
Not suitable for large data transmission, cloud communication requires an additional gateway.
3、ZigBee
Small data volume, low-power networking, two-way communication, smart home applications are mostly, mature solutions can achieve 200 points of control;
There are requirements for field wiring, and cloud control requires an additional gateway.
4、Lora
Narrowband wide area network, 433Mhz low frequency is the main, module communication distance is 2-4KM, suitable for small data volume, long-distance control, easy network distribution, use free frequency band;
Since the operator has not yet supported it, the operating environment is for corporate customers.
5、NB-IOT
Operators support narrowband Internet, which is suitable for low power consumption, small data volume, and wide area network connection.
The user’s real-name system has an annual fee, which is suitable for remote control and mobile scenarios.
6、2.4G
Low-cost remote control, one-way communication, the communication distance is about several hundred meters, and the price is low, suitable for one-way remote control equipment.
7、433M
Low frequency, strong penetration ability, mostly used for one-way data collection and smart home single-point control.
8、4G / 5G
Supported by operators and using mobile networks, the cost is currently high for large data transmissions.
9、GPRS
2.5G frequency band, the transmission data volume is not large, it is used for data collection of operators.
