I think the safety concern is valid, but it's more a wakeup call for the government than for people getting rid of radios. The new text messaging alerts system needs to be built as robustly as our radio alerts. Given the low bandwidth needed for text messaging, it's likely that this goal is not only workable but will result in a more robust system as the end result.
- knowtheory 14y agoMaybe people just don't understand how radio and cell phones work? Cell phones need scores of towers and fiber running to towers in order to connect to a telephone network. You have a network of them. Disrupting either the physical towers or the cabling that connects them incapacitates that part of the network. Worse yet, the more towers drop, the higher the network congestion gets (which can further jam whatever nodes are still up and available). Radio has a gigantic broadcast tower (or maybe some repeaters too), that blasts electromagnetic waves across a large region, and, so long as you have power and your tower is intact, you can reach every radio in your listening area.
