Passive Tags

Hello,
We are studying to develop RFID solutions for the (in-house) logistics market, using LORA devices (operating at 915 Mhz) to inventory and control non-pallet inventory and we are uncertain about the feasibility of identifying passive tags without battery, with LORA devices (even associated with third party hardware).

Hello,

I remember seeing reports of successful experiments of that kind, a quick google trawl gives some results (https://dl.acm.org/doi/10.1145/3130970).

LoRa trades sensitivity with time, so packets can be very long for a longer reach, so most probably the spreading factors and/or output power should be reduced to be able to employ these techniques.
