"This paper discusses the architecture and the performance of a burst transceiver operating in the 434.42-MHz instrumentation, scientific, and medical (ISM) band. The authors have presented a burst transceiver design that can be used as an interrogation unit as part of any passive wireless surface acoustic wave (SAW) sensing system operating in the 433-MHz band," scientists writing in the journal IEEE Transactions on Instrumentation and Measurement report.
"Passive wireless SAW sensing systems are ideal for use in inhospitable and inaccessible environments. The power level and duration of the burst signal can easily be adjusted by changing the attenuation level ...
