I was wondering if it would be possible to create a rudimentary (indoor) location system using three or more Indoor Gateways and a simple Node sending a ping periodically.
Does the Node transmit to all Gateways in range or does it just pick the one thats closest/latest/…? If a single message is picked up by multiple Gateways, would the data show each Gateway with the respective RSSI for each? This way we could do triangulation, right?
I know there is lengthy discussion about Location by triangulation but this goes more in-depth about using timing between send/receive moments to provide a more precise location. Also it seems to be centered at outdoor long range.
