UHF 무선 주파수 식별(RFID)은 장거리 자동 식별 애플리케이션 분야에서 상당한 관심을 불러일으켰습니다. UHF RFID는 다른 RFID 및/또는 다른 무선 시스템과 주파수 대역을 공유하므로 충돌 방지 속도를 크게 저하시키지 않고 얼마나 많은 간섭을 적용할 수 있는지 결정하는 것이 중요합니다. 본 논문에서는 비트 인코딩과 간섭 유형을 고려하여 잘못된 통신 링크를 고려하여 실제 환경에서 RFID 충돌 방지를 위해 허용되는 링크 품질을 논의합니다. 우리는 프로토콜 시뮬레이션 및 수학적 분석과 함께 실험적으로 허용 가능한 링크 품질의 정량화에 접근합니다. 무선 프로토콜은 프레임 슬롯 ALOHA를 채용한 국제 표준 프로토콜을 사용하였다. 이러한 조사를 위해 현재 저자는 프로토콜 시뮬레이터를 개발했습니다. 시뮬레이션 결과는 포아송 분포(Poisson distribution)를 기반으로 한 분석값과 비교되었습니다. 반환(태그에서 리더로) 링크와 전달(리더에서 태그로) 링크에 대한 조사를 별도로 분석했습니다. 프로토콜 시뮬레이션 결과 일반적으로 Pulse Error Rate 10을 확보하는 것이 중요합니다.-4 또는 64개 이하 태그의 충돌 방지를 위해 반환 및 전달 링크 모두에서 더 좋습니다. 애플리케이션에 빠른 충돌 방지가 필요하지 않은 경우 반환 링크의 품질이 완화될 수 있습니다. 반면에 순방향 링크의 성능 저하로 인해 중요한 명령이 손실되어 충돌 방지 속도가 극도로 느려질 수 있습니다. 간섭의 주요 소스가 간섭하는 판독기에서 발생할 때 필요한 링크 품질이 반환 링크에서 최대 10dB까지 완화되고 순방향 링크에서 5dB까지 완화될 수 있다는 것이 실험적으로 측정되었습니다.

Abstract: UHF radio frequency identification (RFID) has gathered significant interest in the field of long-distance automatic identification applications. Since UHF RFID shares the frequency band with other RFID and/or other wireless systems, it is important to determine how much interference can be applied without causing a significant degradation of anti-collision speed. In this paper, the permissible link quality for RFID anti-collision in a practical environment is discussed by considering an erroneous communication link, taking into account of bit encoding and the type of interference. We approach the quantification of permissible link quality experimentally along with protocol simulations and the mathematical analyses. An international standard protocol, employing frame slotted ALOHA, was used as the air protocol. For these investigations, the present authors developed a protocol simulator. The simulation results were compared with analytical values based on Poisson distribution. The investigation in the return (tag to reader) link, and the forward (reader to tag) link, were analyzed separately. As result of the protocol simulation, it is generally important to secure the Pulse Error Rate 10-4 or better in both return and forward links for the anti-collision of 64 or less tags. The quality of the return link may be relaxed when the application does not require fast anti-collision. The degradation of the forward link, on the other hand, may entail loss of important commands, resulting in extremely slow anti-collision. It is measured experimentally that the required link quality can be relaxed by up to 10 dB in the return links and by 5 dB in the forward link when the primary source of interference originates in the interfering readers.

AB - UHF radio frequency identification (RFID) has gathered significant interest in the field of long-distance automatic identification applications. Since UHF RFID shares the frequency band with other RFID and/or other wireless systems, it is important to determine how much interference can be applied without causing a significant degradation of anti-collision speed. In this paper, the permissible link quality for RFID anti-collision in a practical environment is discussed by considering an erroneous communication link, taking into account of bit encoding and the type of interference. We approach the quantification of permissible link quality experimentally along with protocol simulations and the mathematical analyses. An international standard protocol, employing frame slotted ALOHA, was used as the air protocol. For these investigations, the present authors developed a protocol simulator. The simulation results were compared with analytical values based on Poisson distribution. The investigation in the return (tag to reader) link, and the forward (reader to tag) link, were analyzed separately. As result of the protocol simulation, it is generally important to secure the Pulse Error Rate 10-4 or better in both return and forward links for the anti-collision of 64 or less tags. The quality of the return link may be relaxed when the application does not require fast anti-collision. The degradation of the forward link, on the other hand, may entail loss of important commands, resulting in extremely slow anti-collision. It is measured experimentally that the required link quality can be relaxed by up to 10 dB in the return links and by 5 dB in the forward link when the primary source of interference originates in the interfering readers.
