There are a few robust options you may have at your disposal if you’re looking for quality communications in remote areas where traditional cell and data plans don’t work, and one of the most popular and notable today is the satellite phone. What exactly is a satellite phone, how does it work, and how does it compare to cell phones and other common forms of long-distance communication?
At International Satellite Services, we’re proud to offer an unmatched range of satellite phones and portable satellite internet devices, including providing access to top satellite networks like Ligado, Inmarsat and Iridium. Here are some basics on what satellite phones are and how they work, the kinds of features they can be equipped with, and how they compare to cell and other networks.
What is a Satellite Phone?
If you’re just learning about satellite phones, you might be wondering what exactly they are. A satellite phone is essentially a mobile device that connects to orbiting satellites in space rather than relying on traditional cellular ground networks for communication. This allows for coverage and connectivity even in remote areas where cell towers are not available.
How Do Satellite Phones Work?
Satellite phones operate through the use of Low Earth Orbit (LEO) satellites or Geosynchronous Earth Orbit (GEO) satellites. LEO satellites are closer to the earth and create smaller coverage zones, while GEO satellites cover larger areas but have higher latency due to their distance from the earth.
These satellites act as relay stations between satellite phones and ground-based systems, allowing for communication between devices. When a call is initiated from a satellite phone, the signal is sent to the nearest satellite and then relayed to a ground station, which connects to the public switched telephone network (PSTN) or internet.
Features of Satellite Phones
Satellite phones come equipped with various features that make them useful in remote areas. Some common features include:
- Voice calling: Satellite phones function just like traditional cell phones, allowing users to make voice calls.
- Text messaging: Many satellite phones also have the ability to send and receive text messages.
- GPS tracking: Some satellite phones have built-in GPS capabilities, allowing for location tracking and emergency services.
- Data transfer: Satellite phones can also be used to transfer data, such as emails and small files.
- SOS button: In emergency situations, satellite phones often have a dedicated SOS button that can send your location and a distress signal to emergency services.
How Do Satellite Phones Compare to Other Networks?
Satellite phones are unique in their ability to provide coverage in remote areas where other networks may not reach. Some key differences between satellite phones and other networks include:
- Coverage: While traditional cell phone networks rely on ground-based towers, satellite phones use orbiting satellites for connectivity. This allows for coverage even in remote locations such as oceans, mountains, and deserts.
- Cost: Due to the technology involved, satellite phones tend to be more expensive than traditional cell phones. However, it’s important to consider the coverage and convenience they provide in remote areas.
- Call quality: Satellite phone calls may have a slight delay due to the signal being relayed between satellites and ground stations. Additionally, as with any network, call quality can vary depending on location and weather conditions.
- Data speeds: Satellite internet speeds are generally slower than traditional cellular or broadband connections due to the distance signals must travel between devices and satellites.
Satellite phones offer a reliable means of communication in remote areas where traditional networks may not reach. With features such as voice calling, text messaging, GPS tracking, and an SOS button, they provide essential connectivity for those in remote or emergency situations.
