Those idiots!
They should never have shut that down. Sure, it might have been used to support drug cartels etc. and so on, but it is one of the most advanced communications systems available.
Go find a cellular provider that runs their entire infrastructure on solar power, and who has their network de-centralized (meshed) such that it's difficult to take down.
There is no mistaking it, the drug cartels have developed a superior communications system, and it was just shut down. I'm going to build my own version of this thing to cover the island I'm currently on.
Make no mistake, the drug cartels have an incredible amount of financial power, and they are only now starting to use it for potentially good development. Take the hi-tech underground tunnels, the hi-tech submarines, and now the advanced solar mesh network. Someone needs to partner with these guys.
