In recent events, I learned that some pagers only have receivers. How are discrete messages sent to these devices? How is it authenticated? How do they know the device got the message?

But… 2-way pagers also exist. I’ve known nurses that had them for work.
Yeah and my guess is that they’d be less private because if they act as a transmitter, I think they could potentially be triangulated.
