Description
Product Description
The module adopts the MODULATION and demodulation design of NB-iot module, which perfectly solves the problem of decentralized ultra-long distance communication in complex environment with small data volume. Compared with the traditional modulation technology, THE HAC-NBI module also has obvious advantages in the performance of suppressing the same frequency interference, which solves the disadvantages of the traditional design scheme that cannot take into account the distance, disturbance rejection, high power consumption and the need for a central gateway. In addition, the chip integrates an adjustable power amplifier of +23dBm, which can obtain a receiving sensitivity of -129dbm. The link budget has reached the industry-leading level. This scheme is the only choice for long-distance transmission applications with high reliability requirements.
Parameter Function
Nb-iot base station can be used without a central gateway
Supports a variety of low-power operation modes
High-performance 32 bits microcontroller
Supports low power serial port (LEUART) communication, TTL level 3V,Baud rate up to 9600bps
The semi-transparent communication mode communicates with the server directly through a low-power serial port
Compatible NanoSIM \ eSIM
Read parameters, set parameters, report data, and deliver commands through the low-power serial port
HAC communication protocol must be matched, or protocol can be customized as required
The server protocol is resolved by COAP+JSON
It can read parameters, set parameters, report data, and deliver instructions through the low-power serial port
