Communication module: the key device to realize the intelligent connection of everything

Wireless mobile communication module is a module that integrates chips, memory, amplifiers, antenna interfaces, functional interfaces, etc. on a circuit board.

It realizes the functions of enterprise radio wave transmission and reception, lte m2 channel noise filtering and mutual conversion between analog control signals and digital economic signal processing.

IoT intelligent end-users use wireless communication modules to access the service network to meet these data analysis wireless transmission development needs, wireless communication modules are the key equipment to achieve a smart connection of everything.

The value of the module is mainly focused on two aspects: First, the module as an integrated chip, integrated with different application scenarios (2G/3G/4G/5G/5G/NB), providing more stable hardware communication, simplifying the work of application vendors;

Second, the module manufacturers provide the programming system (Android, linux, etc.) according to the needs of the application manufacturers.

Application manufacturers do not have to directly face the chip and software, but only need to know what network to access, in which system to develop applications, and then purchase off-the-shelf custom modules.

Module classification: NB-IoT, 4G and 5G will become mainstream in terms of volume

According to the communication protocols supported by baseband chips, we divide wireless modules into communication modules and positioning modules, which can be divided into cellular modules and non-cellular modules, and positioning modules into GNSS modules and GPS modules.

Cellular communication modules mainly include 2/3/4/5G, NB-IoT and eMTC in authorized bands, while non-cellular communication modules mainly include WIFI, Bluetooth, zigbee, LORA and sigfox in un-authorized bands.

In the future, with the gradual replacement of 2G/3G, the capacity of NB-IoT, 4G and 5G will become mainstream.
