Some individuals pick to keep a satellite phone as part of their disaster preparedness kit. An earthquake, hurricane, terrorist attack, or numerous other points can disrupt each normal landline mobile phone and wireless mobile telephone assistance. But - in theory - satellite phone service must be capable to survive all such disasters, since the satellites are safely distant, somewhere way up inside sky.
Nevertheless, satellite cell phone service also has an Achilles Heel. That is the point at which a telephone contact is routed through the satellite that received your signal towards the ultimate person you are calling. Within the circumstance of most services, your call is routed from the satellite and instantly to its closest ground station, after which it goes from the ground station, as finest it can, to its last destination. If its last destination is another satellite telephone, it travels back up to a different satellite and down towards the mobile phone, wherever it may well be.
This means, for most satellite phone solutions, there remain ground based vulnerabilities. However, Iridium is the notable exception to this. If you are calling to one more Iridium cellular phone, your call goes directly out of your telephone towards closest available satellite , then is routed among the satellites until reaching a satellite that can then beam the phone down towards the recipient.
This capability makes Iridium essentially the most robust network for handling ground dependent disasters.
In theory a single Iridium satellite can handle up to about 1100 calls simultaneously, as well as the total Iridium system some thing less than 66 times this amount. These are not very big numbers, but neither could be the complete installed based of Iridium users quite large, so one particular would expect that, in some form of regional emergency, the Iridium network could handle its users' wants without having appreciable congestion.
A great illustration of this was with Hurricane Katrina. The hurricane knocked out over three million landline circuits and over 1000 cell sites. Three weeks later, only 60% with the cellular mobile phone networks had been operational and two million calls were nonetheless failing. On the other hand, Iridium's network was completely unaffected, and for your initial 72 hours of Katrina, Iridium visitors inside the Gulf area elevated far more than 3000%. The number of subscribers in affected areas grew 500%.
