1.   Introduction 

The  LRA-900-E  is  a  Ethernet  to  radio device designed for 

remote communication operating in a transparent way and 

exploiting the physical layer of LoRa (Long Range) 

transmission technology. 

By using the VxComm 

Driver/Utility, the built-in  RF  port of the LRA-900-E  can be 

virtualized to a standard PC COM Port in Windows. 

Therefore, users can transparently access RF datas over the 

Internet/Ethernet via COM Port program. 

 

The LRA-900-E provides a maximum line of sight (LOS) transmission distance of 1500 meters at 

an RF bit rate  10,000 bps. In order to overcome the interference that may be encountered in 

harsh environments, the LRA-900-E  allows the RF transmission bit rate to be configured to a 

minimum of 250 bps, enhancing the capability of the modem to resist noise and other 

interference. Additionally, the RF channels and Group IDs are adjustable, which is helpful to 

avoid interference encountered when two LRA-900-E networks are adjacent. The RF channels 

and the Group IDs can be configured in order to distinguish and control the different LRA-900-E 

networks.
