Interesting. I wonder how missed calls work.

The distances and remoteness mentioned in the article are impressive. And is the human need and ingenuity for communication.

Reminded me if William Gibson's descriotion of 1950s farmers in the US using metal wire fences as radio antennas.

In the 70s and 80s (and probably before) in the UK, the BBC used to broadcast occasional "sos messages" [1] prior to the main daily news summaries on FM radio - for people who were away from home and, for whatever reason, uncontactable. They usually related to a relative being dangerously ill. I remember hearing them on my parent's car radio on summer camping trips.

Obviously the uk is a small and quite densely populated island but, without two way personal communications, some needs were similar to those described in the article. It changed a lot of things.
