@alan Oh, I think this specific example was from someone selling it on eBay at the time. I don't think it was actually on a network
@alan I'm not sure if they actually use pagers in the factories. The messages I was decoding were things like pressure measurements, so I think they just used the same frequency / protocol.
I think the reason they are used in hospitals is that can still get a signal deep in the bowels of a building, where mobiles struggle.
@jamie Don’t pagers use some of the old GSMR frequencies? I didn’t think they were that great at penetrating structures.
@alan Yeah, I think so. My understanding is that the signal is delivered with more power, so penetrates better - but I don't know much about this stuff.
Apparently they are getting phased out by the NHS, but GOV.uk says:
"The NHS uses around 130,000 pagers at an annual cost of £6.6 million. More than one in 10 of the world’s pagers are used by the NHS."
This is a private instance for family and friends only.
