Measurement of Effective Reading Distance of UHF RFID ...

For UHF RFID applications, tag usability is a very rough indicator and cannot characterize the performance of a tag accurately. In practice, effective reading distance is the key performance index of a tag. This study proposes chip's turn-on power...

Passive UHF RFID tag performance characterization and ...

In this thesis Passive UHF RFID Tag Performance characterization and prediction is investigated. To perform tag characterization, we carry out various path loss measurements. Our path loss measurements with varying distance reveals that received power at the reader is not proportional to d to the 4th power as expected from the radar equation. It is deduced that the radar cross section of the RFID Tag is not constant and varies nonlinearly with incident power. Therefore, a power transfer function is investigated to characterize tag backscatter power as a function of incident power. The...

INTRODUCTION TO RFID

UHF (Ultra High Frequency) RFID Standards and Frequencies

In the UHF (Ultra High Frequency) band, where RFID tags work according to the principles of the electromagnetic coupling, the most popular technology at the moment is the one based on the ISO 18000-6C protocol, best known as EPC Class 1 Gen 2 or for short Gen 2. The EPC Class 1 Gen 2 standard was proposed by the...

Abstract--Temperature monitoring is important in a num-

ber of fields, particularly cold supply chain applications. Most

commercial wireless temperature sensors consist of transceivers,

memory and batteries to maintain a temperature time history but

this is expensive and allows for limited sensor deployment. In this

paper, we propose a low cost...

Abstract--The efficiency of cold supply chain operations can

be improved with pervasive temperature sensing. In this paper,

we investigate the design of a low-cost, single-use RFID based

temperature threshold sensor that is capable of relating the

violation of a temperature threshold to a shift in the optimal

operating frequency at which the tag antenna is well matched

to the tag IC. This shift...

Table 1. Comparison of the Typical RFID Read Range According to Frequency Band (Passive Tags)

While Table 1 compares the read range of passive tags, note that there are actually three RFID tag types: active, passive, and semiactive. Because active and semiactive tags use an onboard power source to power the tag response, they are typically capable of much longer read ranges. Passive tags, on...
