And it was a pun by Ericsson engineers, as they used Erlang to program telephone switches where the capacity planing included Erlangs.

And Apple was involved in that as well, even if it was not planed. The pod in podcast coming from iPod after all.

But only for those areas with receiver coverage that feeds them.

But your own receiver will always cover your area.

SMS routing and billing systems did cost money. Especially billing, as the standards had nothing for it, so it was done by 3rd party software for a very long time.

M12 gets old quick if you do a lot plug/unplug cycles.

Not a single telco wants this. So it does not get built.

Interestingly DECT NR+ is a 5G standard on dedicated spectrum and has been designed to be a mesh from the start.

Viasat fixed modems got bricked at start of the war in Ukraine and some collateral one's in border areas.

The cheapies are less useful for debugging real problems, due to their bad UI and severe limitations.

A good, fast reacting multimeter is likely better thing to get than a cheap scope.

That said the cheapies might be usable for debugging audio stuff.

Can be done more cheaply if tou are good at reusing things and building.

Proper PoE sources have active per port current monitoring and will disable the PoE power in case of an over current event.

All mosfets are like that. The marketing folksbL at Toshiba just were not able get it removed, or they have had one too many complaint from folks running them near the absolute max while not cooling them properly.

Naturally there needs to be filtering and some sort of analog frontend. My main point was that mainstream rigs now do direct sampling, instead of zero-if or superhet with dsp IF.

And WSPR sure is magic, people do thousands of km with it off an rp2040 gpio pin.

The popular IC-7300 transceiver from Icom does that. Receiver samples the whole band and does downconversion in the digital domain (DDC) and same for the transmitter (DUC).

On the hobbyist side there is the TRX Wolf by UA3REO.

Interesting project. They have definitely raised the bar for FOSS ECAD software with their major contributions to KiCAD for example.
