What Is Satellite Phone? | How To Works Satellite Phone?

Satellite phones are mobile devices that do not receive their signal via terrestrial towers, but rather from satellites in orbit around the Earth. A satellite telephone, satellite phone, or sat phone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites.

They provide similar functionality to terrestrial mobile telephones; voice, short messaging service and low-bandwidth Internet access are supported through most systems.

Security of Satellite Phone:

Global star provides a one-way data uplink service, typically used for asset tracking.

When the alert is received on the satellite phone it must be taken to an area with better coverage before the call can be accepted.

Some satellite phone networks provide a one-way paging channel to alert users in poor coverage areas of the incoming call.

Cost of Satellite Phone:

While it is possible to obtain used handsets for the Thuraya, Iridium, and Global star networks for approximately US$200, the newest handsets are quite expensive. The Iridium 9505A, released in 2001, sold in March 2010 for over US$1,000.

Since most satellite phones are built under license or the manufacturing of handsets is contracted out to OEMs, operators have a large influence over the selling price.

Satellite phones are purpose built for one particular network and cannot be switched to other networks.

Why Use to Satellite Phone?

In short, because cell towers aren’t always reliable. If one gets knocked out and others get flooded with calls in the case of an emergency or a disaster, the network can quickly become overloaded.

If you’re in a particularly remote area deep in the mountains or desert, out at sea, or very far north or south you might not be able to communicate with a tower, leaving your cellular phone useless.

How to Work Satellite Phone?

Satellite phones boldly go where cell phones can’t. They let you make phone calls from almost anywhere because their primary infrastructure is literally out of this world. Satellite phones don’t rely on a terrestrial cell phone network. Instead, they beam their data directly to and from satellites orbiting Earth. The gateway then routes the call to its destination using the regular landline and cellular networks.

The Global star constellation is made up of 48 satellites and every call is relayed by up to 4 satellites down to Globalstar gateways on Earth. Clifton, Texas is home to one of the major Global star gateway that services the US. What were once luggage sized bricks that made only voice calls are now slender smartphones with capabilities limited only by your imagination.
