LoRaWAN Dual-mode Meter Reading Module
The HAC-MLLW LoRaWAN dual-mode wireless meter reading module is developed based on the LoRaWAN Alliance standard protocol, with a star network topology. The gateway is connected to the data management platform through a standard IP link, and the terminal device communicates with one or more fixed gateways through the LoRaWAN Class A standard protocol.
The system integrates LoRaWAN fixed wireless wide area network meter reading and LoRa Walk-by wireless handheld supplementary reading. The handhelds can be used for wireless remote supplementary reading, parameter setting, real-time valve control, single-point reading and broadcast meter reading for the meters in the signal blind area. The system is designed with low power consumption and long distance of supplementary reading. The meter terminal supports various measurement methods such as non-magnetic inductance, non-magnetic coil, ultrasonic measurement, Hall sensor, magnetoresistance and reed switch.

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.
