To estimate angle and range the system uses a two-dimensional MUSIC algorithm. A four channel phased array is used to experimentally verify the estimation of angle and range for an EPC gen2 tag. The system is calibrated for phase offsets introduced by hardware as simulations show the sensitivity to these offsets. Experiments with this calibrated receiver array give inaccurate ranging estimates. A solution is to calibrate the system for every angle, allowing meaningful range estimates. Experiments in a different environment show a reduced result, indicating the need for extensive calibration.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125212968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is affected by some interference issues. This paper is focused on the interference between Ultra high frequency (UHF) RFID systems and devices that communicate according to the Global System for Mobile Communications (GSM) standard. Since the GSM and the UHF RFID frequency bands are close, the mobile phones communication can affect the efficiency of RFID systems. In this paper, an experimental analysis on the interference between GSM and UHF RFID is presented. The experimental results highlight the negative effects of the use of GSM devices in the proximity of operating UHF RFID systems. Moreover, the main elements that should be taken into account during the design of an RFID system that works in the same area with GSM devices are identified.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115584414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern RFID applications require efficient tag identification mechanisms to improve performance. Recently, a new approach has arisen to enhance the identification process in an RFID network. This new approach considers the inclusion of an additional device in the RFID network, which leads to an augmented RFID system. Up to date, the are only few proposals taking such approach into account, being the most interesting those that extend the interrogation zone of an RFID reader. However, the performance of such proposals has not been evaluated yet. In this paper, we review an augmented RFID system to evaluate its performance and study its advantages and limitations. Moreover, we design an anti-collision protocol for such system taking advantage of such features. Our proposed protocol is EPC Class-1 Generation-2 standard compliant. We evaluate an augmented RFID system along with our proposal in terms of identification delay to find that it is able to highly reduce such parameter, with gains of up to 40% when compared with a well known multi-reader scheme.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124106804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this technology, the phenomena known as the tag collision problem is becoming increasingly important, since it leads to a wastage of bandwidth, energy, and an increase in identification delay. There- fore, anti-collision protocols are required to mitigate collisions. Tree based protocols constitute one of the two main types of Radio Frequency IDentification (RFID) anti-collision protocols. Inside this group, Collision Tree (CT) protocol constitutes a representa- tive strategy, since some other strategies are based on it. The focus of this work is to design and evaluate with VHDL the CT tag's chip design in order to extract the number of clock cycles required by the reader to identify a set of tags. A stability analysis is also per- formed. Simulations results show that the total number of clock cycles is linearly influenced by the tag's ID length.","PeriodicalId":205916,"journal":{"name":"2015 International EURASIP Workshop on RFID Technology (EURFID)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133732838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
