(HNP) of the World Bank's Human Development Network. The papers in this series aim to provide a vehicle for publishing preliminary and unpolished results on HNP topics to encourage discussion and debate. The findings, interpretations, and conclusions expressed in this paper are entirely those of the author(s) and should not be attributed in any manner to… (More)
The Radio Frequency Identification S ystem, a wireless communication system, recently is applied to vehicular identification; this motivates the analysis of the propagation environment for outdoor RFID systems. The RFID S ystem applied to the vehicular identification consists of the reader, the tag and the radio channel, which is made up by the ground… (More)
Most terrestrial wireless communication systems operate in environments that present a multitude of RF propagation problems. The Radio Frequency Identification (RFID) System, a wireless communication system, applied to vehicular control, is a typical point to point communication system, which one, the radio link formed between the reader, working at the… (More)
Recently Terrestrial Digital Television, TDT, has been implemented in Mexico, as a consequence, the 700 MHZ UHF Band has been opened to new telecommunications services, particularly wireless mobile communication. This technological advance means an antenna design challenge due to it is necessary to design a dual frequency antenna which dimensions must be… (More)
Workflow modeling is a research area that has been explored by more than one decade.
El enfoque de este artículo está orientado a la pérdida en la trayectoria del sistema de comunicación RFID aplicado al control vehicular, debido a un desacoplamiento entre la polarización de las antenas y a las reflexiones en la superficie. Mediciones experimentales fueron llevadas a cabo en campo y en el laboratorio de compatibilidad electromagnética.
