Hi @chuckberry,
UWB is not an efficient technology (due to high RX current) for discovery phase. Therefore, we are typically relying on out of band methods (normally BLE) for discovery and UWB activation. In your scenario, you could use BLE for determining which cluster you are in and then use 1 to Many UWB ranging as described in this tutorial.
In terms of the device to use, I would recommend to start with DWM3001C as it is a module which incorporates a BLE chip, nRF52833.
