I have absolutely seen this sort of thing in a major US city.
I believe many (most?) US hospitals have switched to secure paging services delivered via smartphone. HIPAA pretty much requires it.
nope. bust out multimon-ng with an rtl-sdr and listen on 929.625 give or take a few 12.5khz channels, and you will see a ton of PHI.
In the seattle area, there's still a ton of hospital POCSAG traffic, but no PHI as far as I can tell. Its usually stuff like "go to room 314" or "call 206-blah-blah"
As of a few minutes ago there is still PHI going out in the air. And this is in Seattle.
Which frequency were you listening to? I know there's a few different ones.
What kind of PHI are you getting? Is it from first responders or hospital sources?
Hospital staff. Patient names, hospital record numbers, medication names, dosage amounts, detailed descriptions of their issues (which can be graphic).
Interesting. Are you getting this information using the same method as the parent user I asked?
