There are many kinds of wireless modules in the market now, such as NB-IoT module, LORA module, cellular communication module, Wi-Fi module, LTE module, etc. Various kinds of wireless modules are emerging, giving manufacturers more choices while dazzling many IoT people with no idea how to choose. What is a wireless communication module, and iot wifi module what is the relationship between wireless communication module and IoT?
Radio communication module classification.
The relationship between radio communication module and IoT.
Radio communication module is the basic hardware link of IoT application communication, and it is also the key link to connect IoT sensing layer and network layer. There is a one-to-one correspondence between the radio communication module and the IoT terminal device.
It enables various IoT terminal devices to have network information transmission capability and is the information portal for various intelligent terminals to access the IoT. In IoT, it is the key to connect the sensing layer and the network layer. all device data generated by IoT sensing layer terminals need to be converged to the network layer through the wireless communication module, and then remotely manage and control the devices through the cloud management platform to perform data analysis and improve management efficiency.
As we all know, IoT is a long industry chain. There are modules in the upstream of the chip, and there are terminal applications in the downstream ...... So, what is the value of the module?
Radio communication module industry chain.
As far as the industry chain is concerned, the upstream of wireless communication module is based on the production raw materials such as baseband chip, which is highly standardized. Below are the application areas for each segment. These two application areas are very fragmented and often flow to different areas through intermediate distribution agent links. The model of module companies is usually that they purchase their own upstream raw materials, are responsible for product design and sales, and outsource production to third-party processors. In the upstream, the baseband chip (communication chip) is the core, accounting for about 50% of the material cost.
Due to the wide application of IoT, the downstream industry is very fragmented. By the size of the application market, it can be divided into large particle market and small particle market. Large-scale market (see below) has a large number of IoT modules, high standardization and fierce competition. Suitable for high revenue brand building. There may not be many research developers, but the market development capability is strong.
What is the value of radio communication modules?
Value one: the wireless communication module is integrated in the process of hardware integration and software design, with a variety of communication standards, which can adapt to a wider range of application scenarios.
Value two: the upstream standardized chip downstream with the intermediate link of the decentralized vertical field, need to meet the specific needs of different customers and different application scenarios.
Module manufacturers profit model for independent procurement of raw materials, responsible for product design and sales. They can produce on their own or outsource to third-party processors. Suppliers can customize and develop for different application scenarios according to the requirements of application vendors.
Applicable to wireless communication module.
Radio communication modules are widely used in vehicle monitoring, remote control, telemetry, small wireless network, meter reading, access control system, cellular paging, industrial data acquisition system, wireless tagging, identification, non-contact RF smart card, small wireless data terminal, fire safety system, wireless remote control system, bio-signal acquisition, hydro-meteorological monitoring, robot control, wireless 232 data communication, wireless 485/422 data communication, digital audio, digital image tree, etc.
As the wireless communication module empowers the network information transmission of various IoT terminal devices, it is undoubtedly the information portal to access the IoT for various intelligent terminals, which shows the importance of the wireless module. In the notice of the Ministry of Industry and Information Technology on the construction of IoT, we can see that wireless communication modules such as NB/IoT, LORA, CAT1, etc. will be widely used in the coming years.
