An implantable device shows constant carrier amplitude but achieves better robustness against tissue absorption and noise. Which modulation scheme is most consistent with this observation?

A pacemaker system is designed so that any communication failure cannot be tolerated, especially during remote therapy adjustment.

Which system requirement is being prioritised?

A medical implant uses error correction coding even though the data rate is low.

What is the most likely reason for this design decision?

A doctor interacts with patient data, therapy settings, and system services through an external programmer. Which protocol layer is mainly responsible for this interaction?

An implant experiences unstable signal strength when the patient moves, even though no other wireless devices are nearby. Which interference mechanism best explains this behaviour?

An implant antenna is required to be compact, biocompatible, and suitable for short-range telemetry in pacemakers. Which antenna type best matches this requirement?

An implant system prevents unauthorized commands by verifying device identity before allowing access. Which data security principle is primarily being enforced?

A medical implant communication protocol is designed to prevent data collision when multiple implants operate nearby. Which protocol layer mainly performs this function?

A future implant system replaces RF transmission with ultrasonic or optical links to overcome current limitations. Which category does this development fall under?
