But what level of weather (or other major) event do people expect comms to keep functioning? With the increasing quantity of major natural disasters affecting population centres all around the world, I'd like to see some data on what ends up being the more reliable and available voice comms infrastructure - either old POTS or Wireless? Does anyone know if there have been studies done to show what actually happens in disaster areas, rather than what we all individually may think happens because one day our own lives may depend on the reality rather than the perception? -- Regards, David.
