902MHz~928MHz Long Distance
LPWA Narrowband Module

Model:
TRW-Di9028

TRW-Di9028 (LPWA) narrowband wireless communication module series in October 2021. The TRW-Di9028 long-distance wireless data transmission module is based on IoT long-distance applications. The module complies with the high-power FCC PART 90.205 33dBm specification. High receiving sensitivity.The communication for dozens of kilometers is unimpeded, and it is widely used in the IoT field.  
TRW-Di9028 has maximum power of 32.5dBm and high sensitivity of -130dBm. It provides multi-frequency communication. It has built-in ARM 32bit MCU frame. It is extremely simple in design and application. It can be changed from wired to wireless communication with simple UART communication commands. Built-in Crystal oscillator (TCXO), high stability, fine adjustment of transmit power, 0.2dBm resolution,and small size.
