The UK's Health Service Told To Ditch 'Outdated' Pagers (bbc.com)
The UK's NHS has been told to stop using pagers for communications by 2021, in order to save money. The health service still uses about 130,000 pagers, which is about 10% of the total left in use globally. From a report: They cost the NHS about $8.6 million a year, because only one service provider supports them. Health Secretary Matt Hancock called them "outdated" and said he wanted to rid the NHS of "archaic technology like pagers and fax machines". However, many in the medical industry say that pagers are quick and reliable - especially in emergencies -- and proposed replacements have their own shortcomings.
They should keep the pagers, absolutely. The reason is this:
Pagers use slow transmission protocols that do not need a huge S/N to be properly decoded. That means pagers are going to work almost everywhere you would otherwise get an annoying "No Service" notification on your phone, such as elevators, parking garages, basements, and so on.
It would be a blunder of gargantuan proportions to stop using pagers for critical messaging. Just because the mobile carriers want to take over the pager spectrum for 5G doesn't mean it's the right thing to do.
