There are many different protocols for communication between IoT devices. Here are the five most common industrial communication protocols in IoT applications: LoRa, NB-IOT, ZigBee, WiFi, and Bluetooth, for your reference. 

1. ZigBee

ZigBee is a wireless communication protocol for low-speed short-distance transmission. It is a highly reliable wireless data transmission network. Its main features are low speed, low power consumption, low cost, supporting a large number of online nodes, supporting multiple online topologies, and low complexity. , fast, reliable and safe.

Each network port of ZigBee can access more than 65,000 ports at most, making it gradually become a mainstream technology in the Internet of Things, and has been widely used in industries, agriculture, smart homes and other fields.

2. Wi-Fi

Due to the rapid popularization of home WiFi routers and smart phones in the past few years, the Wi-Fi protocol has also been widely used in the field of smart homes. The biggest advantage of the Wi-Fi protocol is that it can directly access the Internet.

Compared with ZigBee, the smart home solution using the Wi-Fi protocol eliminates an additional gateway, and compared with the Bluetooth protocol, it eliminates the dependence on mobile terminals such as mobile phones. The coverage of commercial WiFi in public places such as urban public transportation and shopping malls fully reveals the application potential of commercial WiFi in scenarios.

3. LoRa

LoRa (LongRange, long distance) is a modulation technology that provides a longer communication distance than similar technologies. IoT products are widely used in LoRa gateways, smoke detectors, water monitoring, infrared detection, positioning, power strips, etc. As a narrowband wireless technology, LoRa uses Time Difference Of Arrival for geolocation.

Application scenarios of LoRa positioning: smart city and traffic monitoring, metering and logistics, agricultural positioning monitoring.

4. NB-IOT

Narrow Band Internet of Things (Narrow Band Internet of Things) has become an important branch of the Internet. NB-IoT is built on a cellular network and only consumes about 180kHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades.

NB-IoT focuses on the low-power, wide-coverage IoT market, and is an emerging technology that can be widely used around the world. It has the characteristics of wide coverage, multiple connections, fast speed, low cost, low power consumption, and excellent architecture. NB-IoT network applications include smart parking, smart fire protection, smart water, smart street lights, shared bicycles, and smart home appliances.

5. Bluetooth

Bluetooth technology is an open global specification for wireless data and voice communication. It is based on a low-cost short-range wireless connection and establishes a special short-range wireless technology connection for fixed and mobile devices. The general effective range is About 10 meters.

Bluetooth enables wireless information exchange between many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. The use of "Bluetooth" technology can effectively simplify the communication between mobile communication devices, and can also successfully simplify the communication between devices and the Internet, so that data transmission becomes faster and more efficient, and broadens the road for wireless communication.

At present, Caimore industrial routers, industrial gateways and other IoT devices are equipped with many IoT communication protocols such as WiFi, cellular network, NB-loT, ZigBee, etc., to ensure the accurate transmission of data and effectively increase the work efficiency of enterprises.
