What is the main difference between cell phones and satellite phones?
The main difference between cell phones and satellite phones lies in how they connect to a network to enable communication. Cell phones rely on cellular networks, which are a series of interconnected cell towers that transmit signals to and from the phone. On the other hand, satellite phones use satellites orbiting the earth to connect to a network.
In practical terms, this difference means that cell phones are generally more widely available and can be used in urban and suburban areas, but may not have coverage in remote or rural areas. Satellite phones, on the other hand, can be used almost anywhere on the earth’s surface, but may have higher latency and lower call quality due to the signal having to travel further to reach the satellite.
How do satellite phones work?
Satellite phones work by transmitting signals to a satellite orbiting the earth, which then relays the signal to a ground station that connects to the public switched telephone network (PSTN). This allows the caller to connect to any phone number, whether it’s a landline or another mobile phone.
The process works in reverse for incoming calls, with the signal being transmitted from the ground station to the satellite, which then relays it to the satellite phone. Satellite phones typically have a clear line of sight to the satellite, which is necessary for the signal to be transmitted successfully.
What are the advantages of satellite phones?
One of the main advantages of satellite phones is their ability to work in areas where cellular networks are not available. This makes them ideal for people who work or travel in remote areas, such as sailors, hikers, or emergency responders.
