Technical questions here about pacemakers and trackers (phone/watch), if anyone knows the answers.
What specific type of transmission mechanisn does a pacemaker use to send info to a watch or phone? Perhaps microwave? (I believe Bluetooth uses microwave) or maybe radio signals?
and
How does the pacemaker know it is connecting to the correct tracker? In other words, if you go into the retirement home tv room and there are four elders with pacemakers and each has their phone or watch, how does the technology make sure each pacemaker only reports to the proper tracker? Serial number or similar when creating the account? Or is there actually a chance they could interfere with each other?
Thanks in advance to anyone who helps me understand how this works.
