We are currently using a single RAK2287/Raspberry Pi running the RAK-customized ChirpStack platform, connected to a cellular modem for backhaul to our servers. This setup yields amazing coverage over the city. (4+ km radius!) I will call this a “RAK Unit” for easy discussion below.
Even so, there are certain areas of the city where this coverage will not reach. So we would like to add at least one more RAK Unit identical to the above. The RAK Units would be separated by some distance, but near enough to each other that it is possible they will both hear some of the same end devices. In other words, there would be overlapping coverage between the two devices.
What is the suggested way to configure a setup with multiple receiver units like this, to ensure end devices can talk to whichever RAK Unit can hear them best? Or is it necessary to add each end device to only one RAK Unit, having pre-determined which unit receives the best signal?
Thanks for guidance!
