Ever wondered how satellite telephones work? A few years ago satellite phones cost in excess of $10,000 and charges for calls were $10 per minute! These days, however, international call charges from a satellite phone are cheaper than a GSM mobile cell phone and coverage is global so if you are, for example, a keen traveler or live in a rural location for weeks or months at a time, a satellite telephone is the perfect way to stay in touch. So! How do satellite telephones work?
Satellite telephones are basically a type of phone that sends radio signals direct to a satellite in space and then down to an earth station. From here, the call is connected to the public switched telephone network (PSTN). Almost as if by magic, you can call anyone, anywhere at any time.
Here’s how a High Speed Satellite Internet Service allows you to use a telephone via satellite:
* The best satellite systems offer telephone and fax over a satellite Internet link via a hardware-based solution that doesn’t require a PC or specific software. This kind of system works via your high speed satellite Internet connection in the same way as your home telephone does.
* High speed satellite Internet remote sites are able to answer normal telephone calls dialed to a standard ten-digit telephone number and 800 numbers. Outgoing calls from the site may use any selected 1+ long-distance carrier, calling cards or 10-10-XXX access.
* Satellite telephones work really well for users in remote locations and using high speed satellite Internet service where access to traditional telephone service is not available. It isn’t really designed to save money on long distance calls.
* Of course the quality of sound you will receive over satellite telephones is similar to that of a cell phone. There is also a slight delay. If a dedicated satellite voice channel with QoS (Quality of Service) is added to your system you can improve on the quality and availability of your service.
* Once the call reaches the remote site, calls are handled by a remote terminal. Where the system joins the ordinary telephone network there is a host terminal. A host terminal can support two or more remote terminals that are configured in a range of ways.
