Get The Most Recent Story About Satellite Mobile Phone -- Disaster Service
Some individuals choose to maintain a satellite phone as component of their disaster preparedness kit. An earthquake, hurricane, terrorist attack, or many other things can disrupt each regular landline telephone and wireless mobile or portable telephone service. But - in concept - satellite cellular phone service should be capable to survive all such disasters, simply because the satellites are safely distant, somewhere way up from the sky.
Nevertheless, satellite phone support also has an Achilles Heel. That would be the point at which a phone call is routed through the satellite that received your signal towards the ultimate person you are calling. Within the case of most providers, your phone is routed from the satellite and immediately to its closest ground station, after which it goes from the ground station, as greatest it can, to its last destination. If its final location is a different satellite phone, it travels back up to yet another satellite and down towards the telephone, wherever it may perhaps be.
This means, for most satellite phone services, there remain ground based vulnerabilities. On the other hand, Iridium would be the notable exception to this. If you are calling to another Iridium cell phone, your call goes directly out of your telephone to the closest accessible satellite , then is routed between the satellites until reaching a satellite that can then beam the phone down towards the recipient.
This capability makes Iridium by far the most robust network for handling ground based disasters.
In concept a particular Iridium satellite can handle up to about 1100 calls simultaneously, as well as the total Iridium network some thing less than 66 times this number. These aren't incredibly large numbers, but neither is the complete installed based of Iridium users incredibly large, so one would anticipate that, in some kind of regional emergency, the Iridium network could handle its users' wants without appreciable congestion.
A great illustration of this was with Hurricane Katrina. The hurricane knocked out over 3 million landline circuits and more than 1000 mobile or portable sites. Three weeks later, only 60% with the cell telephone networks had been operational and two million calls were still failing. Conversely, Iridium's community was completely unaffected, and for the initial 72 hours of Katrina, Iridium traffic within the Gulf area elevated more than 3000%. The quantity of subscribers in impacted areas grew 500%.
