Communication module: the key technical equipment to realize a wise connection of everything
Wireless communication module is a modular component that integrates chip, memory, amplifier device, antenna interface and function interface on the circuit board, which can realize the function of radio wave transceiver, channel noise filtering and exchange of analog signal and digital signal. The IoT terminal is connected to the network through the wireless communication module, which is the key device to realize the intelligent connection of IoT.
The value of the module is mainly focused on two aspects: first, the module as an integrated chip, by integrating different networks, standards (2g/3g/4g/5g/nb, etc.) to meet different application scenarios, provide more stable hardware communication, simplify should; second, the module manufacturer according to the requirements of the application manufacturer, custom record system (android, linux, etc.), provide The basic system for software development. The application manufacturer does not have to deal with the chip and software directly, but needs to know which network to access and on which system to develop the application, and then purchase off-the-shelf custom modules.
The IoT communication module sits in the middle of the sensing and network layers and is the cornerstone of the Internet of Everything. The IoT communication module is the equivalent of the IoT "connector", through which all data generated at the sensing layer needs to be transmitted to the network layer. The module corresponds to the IoT end devices one by one and is irreplaceable. The downstream application scenarios of IoT are diverse, fragmented and explode in sequence, and the IoT modules have common properties. Usually, the increase in the number of IoT connections requires 1-1 additional communication module. IoT communication module, as the "shovel seller" of IoT industry, accompanies the explosive growth of IoT applications and the rapid growth of the number of connections, and the certainty of business environment improvement is high.
Modules for classification: NB-IoT, 4G, 5G uptake will become mainstream
According to the communication protocols supported by baseband chips, wireless modules are classified into communication modules and positioning modules, where communication modules can be divided into cellular modules and non-cellular modules, and positioning modules can be divided into GNSS and GPS modules. Cellular communication modules mainly include 2/3/4/5G and NB-IoT and eMTC in licensed bands, and non-cellular communication modules mainly include WIFI, Bluetooth, Zigbee and LORA and Sigfox in non-licensed bands. In the future, with the gradual replacement of 2G/3G, NB-IoT, 4G and 5G will become mainstream.
Wireless communication technologies can be divided into three categories: high-speed, medium-speed and low-speed, and different types of technologies are applicable to different application scenarios. High-speed 4 g/5 g technology is suitable for large data transmission, high-speed vehicles, network, industrial control, video monitoring and other applications. Low-rate based on lpwan is suitable for small data, slow transmission speed, power-sensitive remote meter reading, environmental monitoring and other scenarios. The development of downstream industries and applications directly determines the development of different wireless modules, as different communication access technologies correspond to different downstream applications and scenario characteristics.
