Disclosed are techniques for wireless communication. In an aspect, a radio frequency identification (RFID) station may receive a first packet from an RFID tag at a first arrival time. The RFID station may receive a second packet from the RFID tag at a second arrival time after the first arrival time. The RFID station may estimate a distance between the RFID station and the RFID tag based on an inter-packet arrival time between the first packet and the second packet, the inter-packet arrival time being based on a time difference between the first arrival time and the second arrival time.
