It is well known that you can't locate target based on GPS indoor, we need to use other technology to finish it.
For data transfering is a basic requirement for most of IT system, it is the best way to realize both functions on same hardware: communication & localization.
I used LoRa to communication before, it is cheap enough, and the communication range is long enough too。
It said we can locate target through LoRa technology, I did not study it yet.
Is there any simple way to locate indoor target with accuracy of 1 meter.
This is what I cared:
1) not expensive;
2) with current product, mass products better;
3) open source better;
4) running projet/application exist .
