Abstract:
Over the last decade radio frequency identification (RFID) technology has grown at a formidable rate, thereby creating new and improved service at lower cost. This is resulted in an increase in number of users and different applications such as an auto parking. This approach provides a nice comfortable, cost economical, well secured, totally unmanned and fully controlled parking space .
The simulation environment of this study based on using MATLAB code for forward link and return link. The simulation is focused on reader side. A simple wireless channel and a simple reflection model of tag are used for evaluating the performance of reader and tag with respect to distance and transmit power.
For a simple analysis, a single reader and a single tag bi-directional communica-tion is investigated to obtain the physical parameters. The communication link is half duplex, reader to tag and then tag to reader.
The system model is developed and a simulation results are presented to show the relation of received power with respect to the operating frequency, transmitter gain, transponder gain and transmit power.
In this study, a detail calculations are performed for designing the sliding gate control circuit .
