Wireless communication module pulls the market growth rate

        In recent years, the Internet of Things (IoT) market has shown explosive growth, according to relevant data forecasts, the number of IoT devices in 2020 will reach 20 billion to 30 billion units, the scale of China's Internet of Things (IoT) industry will reach 2 trillion yuan, and the global IoT market size will grow to 3 trillion U.S. dollars, with a potential market size of more than 7 trillion U.S. dollars.

In the process of IoT application, almost every IoT device needs to support at least one wireless communication protocol in order to realize the interconnection and interoperability with other devices, networks and the cloud.

        With the huge market demand and growth potential, many people can't help but ask what is "communication module"? What kind of key role does communication module play in the IOT industry chain?

Wireless communication module is irreplaceable

        The principle of wireless communication module is to send or receive electromagnetic signals and convert them into information that we can understand. The function of wireless communication module is to connect things with things, so that all kinds of IoT terminal equipment can realize the information transmission ability, and make all kinds of intelligent equipment with the information interface of IoT.

        Wireless communication module is the key link connecting IOT sensing layer and network layer, belonging to the underlying hardware link, has its irreplaceable function, and is the carrier of IOT intelligent terminal.

Classification of wireless communication module

        Wireless modules are divided into communication modules and positioning modules according to networking and positioning functions. The positioning module is mainly based on satellite positioning. Communication modules are categorized into cellular and non-cellular based on the different communication technologies. Cellular communication modules are further categorized into 2, 3, 4, 5G and NB-OT, e-MTC and non-cellular communication modules are categorized into Bluetooth, WiFi, Zigbee, LoRa, sigfox.
