| | Some folks choose to maintain a satellite phone as part of their disaster preparedness kit. An earthquake, hurricane, terrorist attack, or a lot of other items can disrupt both regular landline phone and wireless mobile mobile phone service. But - in concept - satellite phone support really should be able to survive all such disasters, because the satellites are safely distant, somewhere way up inside sky.
Nonetheless, satellite telephone support also has an Achilles Heel. That is the point at which a cell phone phone is routed from the satellite that received your signal to the ultimate person you are calling. Inside the case of most providers, your call is routed in the satellite and right away to its closest ground station, and then it goes from the ground station, as best it can, to its last location. If its final location is another satellite cell phone, it travels back as much as another satellite and down to the phone, wherever it may well be.
This indicates, for most satellite phone services, there remain ground based vulnerabilities. Nonetheless, Iridium is the notable exception to this. If you're calling to a different Iridium phone, your call goes directly out of your mobile phone towards the closest offered satellite , then is routed among the satellites till reaching a satellite that may then beam the call down to the recipient.
This capability makes Iridium essentially the most robust system for handling ground based disasters.
In concept a single Iridium satellite can manage as much as about 1100 calls simultaneously, and the total Iridium network some thing much less than 66 times this number. These aren't very huge numbers, but neither would be the total installed based of Iridium users quite huge, so 1 would anticipate that, in some form of regional emergency, the Iridium system could manage its users' needs without appreciable congestion.
A good instance of this was with Hurricane Katrina. The hurricane knocked out more than 3 million landline circuits and more than 1000 cell websites. 3 weeks later, only 60% of the cell phone networks had been operational and two million calls had been nevertheless failing. Alternatively, Iridium's network was totally unaffected, and with the first 72 hours of Katrina, Iridium traffic in the Gulf area improved much more than 3000%. The quantity of subscribers in affected places grew 500%.
