| This thesis highlights available technologies for an RFID application and also presents a feasibility study for designing an RFID application using a complex programmable logic device (CPLD) in harsh environmental conditions to generate part identification and report locally collected data over wired or wireless links. The CPLD will function as a logic operation unit to receive information from pressure, temperature, and other sensors, and will respond to remote inquiries by driving a radio transceiver with both a digital code stored in the CPLD (part ID) as well as digitally encoded data collected by the CPLD. The radio transceiver can drive an antenna creating a wireless communications link that could be used for remotely interrogated radio frequency identification tag applications. Recent technologies that are feasible for implementation of tagging applications are also discussed. |
