NB-IoT wireless transparent transmission module

HAC-NBi module is an industrial radio frequency wireless product independently developed by Shenzhen HAC Telecom Technology Co., LTD. 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.
