How do satellite phones work?

With a satellite phone you will never be incommunicado

No matter where you are, with a satellite phone you will never be incommunicado. And it is that since their invention, these devices have been responsible for saving lives and providing communication in critical situations or simply when terrestrial networks have failed.

Unlike cellular networks , which can be very vulnerable, satellite networks are rarely out of service, which means that if you have a satellite phone the connection to emergency services, government agencies, family or friends it is guaranteed.

In remote or hostile areas such as the desert, the sea or the depth of the Amazon jungle; As well as in emergency situations or natural disasters, the cell phone becomes a useless device and leaves it totally incommunicado. Well, satellite telephony solves this problem, since it receives coverage from anywhere and at all times.

How does satellite telephony work?

As its name implies, a satellite phone allows the communication through satellites that move around the Earth’s orbit to provide telephone coverage in every corner of the planet.

This means that whenever you are outside and the sky is clear, you will be able to make calls, send or receive text messages or short emails, provide Geolocation data and more.

These devices depend on a network of powerful satellites that are fixed either above the Equator (Geostationary), or in the Low Earth Orbit (LEO, for its acronym in English). 

Geostationary satellites are fixed at a single point on Earth and their orbit is higher than 36,000 kilometers from the planet’s surface, so they can provide the service in a larger area.

Whereas in Low Earth Orbit, satellites are located in different parts of the Earth and fly lower, generally between 400 and 700 kilometers from Earth. The result is greater coverage and better sound quality.

When you make a call, it is transmitted from your phone to the nearest and visible satellite from your position, which after returns the signal to Earth.

All-Proof Terminals

Satellite Phones They are robust, resist the most extreme conditions, withstand scratches, shocks, splashes of water and dust and do not depend on a local ground infrastructure, making them the most effective method for search and rescue agencies in an emergency. < / p>

Also, the satellite telephony guarantees absolute security against espionage or hacker attacks, making it one of An infallible alternative for government authorities and security and defense agencies.

Satellite phones are also traditionally used in the maritime, air and oil areas, in the media, mining or agriculture.

And although it may seem unusual, there are still places with limited cellular coverage or where land line service is non-existent and does not allow make or receive calls normally, which is why many individuals are choosing to buy a satellite phone to meet their vital communication needs.

Greater profitability

Currently, satellite phones are compact, lightweight, light and can be approximately the same size as a cell phone. Some offer a built-in speaker or updated mini-USB data port.

Unlike roaming charges in foreign countries, satellite communication costs the same no matter where you are on the planet. In addition, thanks to Satway -the free application that we have created for IOS and Android- you can receive text messages from your family, friends or contacts at no cost.
