LoRaWAN is a great long-distance, low-power transmission protocol. One of the questions that often comes up after deploying a gateway and nodes is “what’s the greatest distance I can successfully transmit between my gateway and node?” You could watch your Application traffic on The Things Network as you move to strategic locations and see if packets appear. However, an automated approach to this could save time and allow you to cover more ground. To do this, you’ll need a node with a GPS to send its location and software to aggregate the received data on a map to show the node transmission locations. This way you can have the node automatically transmit at a rapid interval as you walk, cycle, or drive to various locations.<\/p>\n\n\n\n\n\n\n\n

TTN Mapper<\/a> is a web-based mapping software that does this from data transmitted to The Things Network<\/a>. However, the issue with TTN Mapper is it does not update in real-time, requiring up to a day to see if your transmissions were successfully received. This limits it’s usefulness if you’re trying to determine transmission distance as you’re on the move, such as I like to do while driving. To overcome this limitation, I developed mapping software that receives the location data from The Things Network and displays it in real-time on a map in a web browser on your phone, tablet, or computer. This map can even display your current location if you permit location sharing. The backend of the software runs in a docker container and has been successfully built and tested on both a Raspberry Pi and a desktop PC running a 64-bit version of Ubuntu.<\/p>\n\n\n\n
