Communication Module LoRaWAN RF Communication Module WFCM-910LR

Company Profile

Willfar Information Technology Co., Ltd.

- Established in 2004;
- Listed on the STAR Market of the Shanghai Stock Exchange in December 2019;
- Leading supplier of meter reading (AMI) equipment and operation service;
- The first company to develop "One DCU Reading Multi-meter" solution in China;
- The first company to have large-scale application of technologies and systems like "CPU smart-card Charge and Control", "One DCU Reading Multi-meter", LoRa-based RF Communication and "District Metering Area (DMA)”

Introduction

- The WFCM-910LR RF module is independently developed by Willfar Information Technology Co., Ltd.

- This module adopts the latest generation of single radio frequency sx1268 chip from SEMTECH, which has the advantages of low power consumption and long communication distance.

- The RF clock of WFCM-910LR adopts 32MHz TCXO active oscillator, which meets the technical standard of LoRaWAN interconnection.

- The transmission distance of the module can reach more than 5 kilometers in the dense urban environment, and the coverage area can reach 10-15 kilometers in the open environment.

- With expanding communication distance, the use of repeaters can be greatly reduced, the design of the system can be simplified, so that the cost can be reduced.

- The low power consumption of the module greatly prolongs the battery power supply time, maximizes the battery life, and improves the network capacity and scalability.
