    I am in need of a seasoned developer with proficiency in working with RF modules and LoRa technology, or similar, to create a system that can compute the distance between two RF modules. I am seeking a skilled developer to create a system that calculates the distance between two RF modules using LoRa technology or a similar module. The system should operate within the 2.4 GHz or sub-GHz frequency bands. Required precision of the measured distance in outdoor environment is 10 meters (can be 100 meters in the first version). If you have expertise in RF communications and embedded software development, I encourage you to bid on this project.
