A Passive UHF RFID System Over Ethernet Cable for Long Range Detection
IEEE Journal of Radio Frequency Identification, 2020Co-Authors: Zhe Fu, Ian H. White, R.v. Richard V. Penty, Michael J. CrispAbstract:This paper proposes a new form of passive UHF RFID system which has high tag detection accuracy but lower costs than existing systems for wide-range RFID scenarios requiring greater flexibility. This new system concept consists of a central baseband controller and a remote antenna subsystem, connected using a twisted-Pair Cable. Baseband signals are transmitted over the twisted-Pair Cable during the inventory session, and the transmitted radio frequency (RF) signals are up and down converted in the antenna subsystem. −88 dBm reader sensitivity is achieved with an active leakage cancellation block, showing little degradation in tag detection performance over a 300m of Cat5e Cable between the controller and the antenna. An average leakage suppression of 36.9 dB can be achieved with a fixed transmission power of 26.5 dBm. Compared with conventional RFID systems using coaxial Cables between the reader and antenna, the presented system is superior in terms of link distance, link cost, and installation flexibility.

RFID-TA - Long distance passive UHF RFID system over ethernet Cable
2017 IEEE International Conference on RFID Technology & Application (RFID-TA), 2017Co-Authors: Zhe Fu, Michael Crisp, Shuai Yang, R.v. Richard V. Penty, Ian H. WhiteAbstract:This paper proposes a new antenna remoting system for ultra-high frequency (UHF) radio frequency identification (RFID). The system consists of a central baseband controller and a remote antenna subsystem, which are connected using twisted-Pair Cable. During the inventory session, only baseband signals are transmitted over the twisted-Pair Cable, whilst the transmitted radio frequency (RF) signals are up and down converted in the antenna subsystem. This new RFID system provides −94.5 dBm of reader sensitivity, and can fulfill long-distance detection tasks with very low performance degradation over up to 150 m of Cat5et Cable. Compared with conventional RFID systems using coaxial Cables between reader and antenna, the presented RFID system is more flexible and cost-efficient due to its low deployment cost and ease of Cable routing.

less wires a novel approach on combined power and ethernet transmission on a single unshielded twisted Pair Cable
2015 IEEE World Conference on Factory Communication Systems (WFCS), 2015Co-Authors: Derk Wesemann, Jens Dünnermann, Marian Schaller, Norman Banick, Stefan WitteAbstract:This paper discusses an alternative to common Powerline or Power-over-Ethernet applications, combining a 100BASE-TX-equivalent full duplex communication and simultaneous DC power transmission on one single twisted Pair wire. The reduction of wires and connections can potentially ease the modularity and reconfigurability of industrial production installations, if the data communication offers a sufficiently high robustness against influences from the DC power transmission. This part of our research focuses on the necessary electrical adaptations between data and power circuitry and evaluates interference scenarios that are common for industrial fieldbus installations.

an electromagnetic topology approach crosstalk characterizations of the unshielded twisted Pair Cable
Progress in Electromagnetics Research-pier, 2006Co-Authors: Phumin Kirawanich, N E Islam, S J YakuraAbstract:Abstract—The inductive effect of near-end crosstalk for a category five unshielded, twisted-Pair Cable has been verified using the electromagnetic topology simulation method. Crosstalk reduction and its dependency on such parameters as driving signals, circuit configuration and impedance, are studied. The simulation results are consistent with analytical analysis. Results show that the straightthrough, differential-generator, twisted-Pair receptor model is the most effective configuration to control the near-end crosstalk level. This is due to the influences from both the neutralizing mutual inductance and the single current generator. The simulation results also show that electromagnetic topology-based predictions are valid only for Cables that are electrically short. Simulations are carried out using a compaction scheme with a single equivalent circuit. As a result, the unshielded, twisted-Pair Cable portion of the circuit can be combined with a larger network for analyzing the overall response of the entire network system.

MINIMIZING CROSSTALKS IN UNSHIELDED TWISTED-Pair CableS BY USING ELECTROMAGNETIC TOPOLOGY TECHNIQUES
Progress In Electromagnetics Research, 2006Co-Authors: Phumin Kirawanich, J. R. Wilson, Naz E. Islam, S J YakuraAbstract:Crosstalk reduction is analyzed for a reconfigured category-five Cable network using electromagnetic topology-based simulation. The reconfigured network results in a marked reduction in inductive near-end crosstalk for the unshielded twisted-Pair Cable network. Analyses show that half-loop shifting of the generator-Pair wires placed next to the receptor is the most effective way to control the near-end crosstalk level. This is primarily due to additional coupling sources induced on receptor wires that effectively deactivate the original cross coupling effect. The analysis also reveals the usefulness of electromagnetic topology-based simulations. The technique applied in this paper is appliCable for any large network systems. A sub-network compaction scheme is critical in creating the equivalent junctions that provide a significant reduction in total computational time and total computer memory requirement for analyzing large network systems. For a 5.28-m long Cable we have considered in this paper, the results are valid up to 10 MHz.
