A satellite phone or sat phone is a type of mobile phone based on the concept of advanced satellite technology, or the ability to connect to orbiting satellites. The phones send and receive calls using orbiting satellites rather than relying on landlines or signals from cells towers. They function like mobile phones and may include voice, SMS service, email, or even low-bandwidth internet access when partnered with a GSM cell network. Dependent on the design of the individual system, coverage may include the entire earth, or only certain regions.
The advantages of using a satellite phone is remarkable despite the increased size of the phone and the high cost. The key is that it only requires an unobstructed line of sight to the sky and can be called from anywhere. A satellite phone will work on a safari in the jungle, atop the Himalayas, or a thorough clearing in the Black Forest.
The satellite phone is an invaluable tool for every trip, whether at sea or in the air, where another type of communication is available. This flexibility is ideal for the military, emergency personnel, or anyone who dares to venture out into the remote areas of a region or the world.
Reliable service at all times is guaranteed. A satellite service is clear of all power outages, bad weather and even a natural disaster.
Support in a disaster prevails. In sudden emergencies, satellites do not become overloaded, but provide seamless communication. During an earthquake, terrorist attack, or local power failure, satellite service is unaffected.
Network coverage is unparalleled and is where cellular or landline coverage is limited or nonexistent.
There are different types of satellite phones based on different specifications. With further advances in satellite technology has opened a satellite phone to customers, not limited to government use. A satellite telephone can be powerful enough to cover the entire globe as its communication range; however, most of the satellite phones available for customers are designed for use within specific zones.
Newer sat phones are small enough for a remote traveler to carry in case of emergencies. Exact coverage depends on the satellite network and its orbital paths, as in Polar Regions or just East Asia. Some networks provide service to the entire earth. Sat phones currently have to be used outdoors with a clear path to the sky, however, in the not too distant future handheld sat phones will be available that work anywhere at all. The advantages of sat phones may be unlimited.
