How can we explain that the passive RFID tags have better range in UHF than in HF although the pathloss is grater in UHF?

Referring to Friis Equation, when the frequency increases the pathloss increases. However, the range of the RFID tags in UHF (from 860 Mhz to 960 Mhz depending on the country) is greater (about 10...
