lpwa 5g

Module introduction:The key to connect the IoT sensinglpwa 5g layer and transmission layer.

Wireless network communication module is the baseband chip, RF chip, power technology management control chip, positioning chip, PN-type devices and resistance and capacitance sense components and other materials can be integrated in the PCB on the functional analysis module, in order to realize the radio wave transceiver, channel noise filtering and analog input signal and digital economic signal devices exist between the interrelationship conversion and other functions. Wireless mobile communication modules need to redesign and integrate different development chips and device structures, involving multiple ways of communication service protocols/standards, volume, power consumption and special production processes. Wireless communication module mainly includes antenna interface, main function test module and function interface, among which: main function demand module is the core of the module, including baseband mode, RF, power enterprise management and storage user module.

Standard classification: according to the communication protocol, the cellular module is the fastest growing and has the greatest potential

Cellular module is the fastest growing and most promising IoT communication module. According to the communication protocol supported by the baseband chip, the wireless module is divided into location module and communication module, including gnss module and gps module, and the communication module is divided into non-cellular module and cellular module. Non-cellular modules mainly include local wireless such as wifi, Bluetooth, lora, sigfox and other non-licensed, wide-area wireless communication modules; cellular modules include 2g/3g/4g and 5g. Cellular communication modules have a wide range of application areas and huge development potential, and are considered to be the main driving force for the high-capacity and rapid development of future communication modules.

Application scenarios:Downstream is wide, different rates and power consumption correspond to different applications.

Communication module design industry downstream enterprise application research field has many, according to the different requirements of module rate and power consumption can be divided into passive IoT, narrowband IoT, low and medium speed IoT and high speed IoT four life scenarios, specifically include through wireless payment, car networking, smart tourism city, industrial technology applications, wireless network gateway, smart security, smart China energy, smart education and medical care, etc. NB- IoT and other LPWA modules correspond to narrowband / low and medium speed IoT and other low-power IoT scenarios, specifics include student wisdom development city, wisdom and energy and other applications, the main feature of such problem scenarios is the module shipments are huge but the unit price level is low. While Cat 4 or above countries and even 5G modules are applied to high-speed, high-value realization scenarios, including those that can automatically control driving, wireless gateways and industrial social Internet, etc., of which routers/CPE is the fastest field of 5G module application capability to land.
