Description
Summary:The ever-growing oil and gas industry has led to the high demand for technologies which accurately sense defects in underground pipelines. Radio frequency identification (RFID) based sensors are a hot topic for use with buried pipelines because they do not require batteries and are low-cost. The issue is most RFIDs do not function well in the presence of metals especially magnetic carbon steel pipes that are prevalent in the Oil and Gas industry. Higher frequency RFIDs in UHF range also attenuate rapidly through different soil compositions. In this work, a comparison between conventional full/half duplex (FDX/HDX) and sequential (SEQ) RFID systems in the VLF and LF bands is detailed. Measurements comparison between the two communication systems in the presence of ASTM A-53 carbon steel pipe show a SEQ RFID system offering 8.3 dBm (6.76 times) improvement over the conventional FDX/HDX system.
