Satellite Phone

These phones look similar to the cellular phones but they differ in the manner in which they function. The satellite phones communicate through the nearest satellite. Today, the satellite phones carry a retractable antenna. These phones come with connectors for external antenna.

Before we discuss the difference lets explore satellite phones.

What are satellite phones? 

These are the phones which communicate through the nearest orbiting satellite. These are the wireless devices which gives you much faster and better coverage than the cell phones which all of us use.

How are the satellite phones different from the cell phones? 

For this let’s understand the basic working of the cell phone as well as the satellite phones.

How the cell phone works? 

The cell phone is called so because it works on the basis of the cells. Whole area is divided into small areas. The small areas are called as the cells. In each area or cell an antenna is installed.
We know these antennas by the name of towers. These towers help in the transmission of the data. As an individual move from one cell to another the cell phone sends a signal to the Mobile Telephone Switching Office.

These Mobile Telephone Switching Offices with the help of their control channel and database relocates the cell phone in another area.

How does the satellite phone function? 

These phones use the orbiting satellites for data transmission and connectivity. As you turn on the satellite phone, your phone gives signal to the nearby low orbiting satellite with which your phone is registered. As you use your phone to make a call, the signal is send to the nearby orbiting satellite. This satellite then connects to the ground or gateway station. The gateway station in turn transmits the signal to the destination or the cell phone to which you are making a call.

Where can you use these satellite phones?

You can take them with you when you go out for expedition, tracking and any holiday journey to a remote area where the cell phone connectivity is not proper.

These phones are designed such that they are not appropriate for indoor purposes. They will give you sufficient connectivity and signals only if the roof of your house is thin enough to transmit the signals and get connected with the revolving satellites in space.

But for external usage they are the excellent ones. You can install the connectors on your building or vehicle and enjoy the coverage. These phones get connected through the country calling codes and thus give you a superior connectivity within your region.
