RFID and NFC Questions

Below are some questions related to radio frequency identification and near field communication that may be asked during or after your oral presentation.

  • What if the size of the scanned objects changes?
  • What did you think of the Friis equation?
  • Can you explain why the Friis equation was not accurate enough?
  • Is there any chance that your co-efficient is not accurate enough?
  • Upon what are your transmitted gain and received gain based on?
  • Did you count measurement errors?
  • Did the measurement errors significantly affect the calculations?
  • Are you sure the angles on the simulated system are the same as the angles on the actual antenna?
  • What happens when an RFID tag is detected by more than one antenna?
  • Do the virtual tags determine granularity?
  • In your experiment, why did you use 3 tags at the same point?
  • If there is interference, why do you use the tags concurrently?
  • Why didn't you place the tags sparsely?
