FM-T-NB/W-NB module is an industrial grade RF wireless product independently developed by our company. The module adopts NB IoT module modulation and demodulation design, perfectly solving the problem of decentralized ultra long-distance communication in complex environments with small amounts of data.

Compared to traditional modulation techniques, FM-T-NB/W-NB module also has significant advantages in suppressing co frequency interference, solving the drawbacks of traditional design schemes that cannot simultaneously consider distance, anti-interference, high power consumption, and the need for a central gateway. In addition, the chip integrates an adjustable power amplifier of+23dBm, which can achieve a reception sensitivity of -129dBm. The link budget has reached an industry-leading level, and this solution is the best choice for applications with high reliability requirements for long-distance transmission.
