Ask The ExpertsWhat Is LoRaWAN—and Does It Interfere With RFID?
RFID Journal Staff asked 4 years ago

I’ve been hearing about LoRaWAN technology lately, and I notice that it operates in the UHF frequency band. Would it interfere or conflict with UHF RFID systems?

Jeff,

A low-power wide-area network (LoRaWAN) is designed to enable battery-powered devices to operate with a long read range of 2 to 3 kilometers (1.24 to 1.86 miles). LoRaWAN devices have a very slow data-transfer rate, so you probably would not want to use it, for instance, to send a 20-megabit file, but it is useful for transmitting senor data. For example, it could be used to transmit information about moisture in soil from a sensor on a farm.

The frequencies used by LoRaWAN systems differ by region and country, as do the frequency bands designated for passive UHF RFID systems. Here is a list of some of the major regions and countries and the frequency bands assigned for passive UHF RFID and LoRaWAN in each:

As you can see, there is definitely overlap, which means LoRaWAN devices and passive UHF RFID devises could, indeed, interfere with one another.
