Yup, but there’s only so much bandwidth you can push at that frequency, so simple text messages are fine, but get any more complicated, and you’ll need more bandwidth.
Also it’s not encrypted in the slightest bit. Nor is it unknown. Nor is it difficult to detect and decode it with widely-available equipment. I could listen to my local hospital’s pager tower with a $35 dongle from several miles away.
What is this device? Oversized pager?
Yes, actually. Probably still using POCSAG, too. Many large hospitals and emergency response departments still use pagers for this kind of stuff.
Pagers operate at a different frequency than phones which has an easier time penetrating thick walls and old buildings.

SDR is fun!
I don’t have much trouble penetrating old—oh, sorry. I misread…
Public safety mdc, likely paramedic given the lack of input ability and heads up positioning.
