Re: Is it that hard
"Why else are we still using f##king pagers and fax machines in hospitals in 2018?"
Pagers run on lower frequencies than cell phones. Lower frequencies are easier to penetrate into buildings, making them better-suited for use deep inside hospitals where cell phone signals aren't guaranteed to reach (I can speak from firsthand experience; once I get well into a hospital, I go Out of Range).
As for fax machines, not only are they easier to deploy to less-sophisticated areas where not even computers are a given, there are legal requirements for hard copies and paper trails (such as for admission in court).
