Abstract: RFID-based location awareness is becoming the most important issue in many
fields in recent years, such as ubiquitous computing, mobile computing. However, the RF system
is noise-limited, which leads to the readers can't read the information from tags timely and
accurately, especially for RFID localization network. This study proposed a novel RFID indoor
localization method based on Received Signal Strength Indicator (RSSI) and Packet Received Ratio
(PRR). To do so, the environmental factors affecting the link quality are analyzed and the location
awareness data is collected by RFID equipment using non-coherent Frequency Shift Keying (FSK)
as modulation scheme and Not Return to Zero (NRZ) as encoding scheme. Then the relationship
model between RSSI, PRR and distance is established based on the classic radio propagation
