Satellite Phone

A satellite telephone, satellite phone, or satphone is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites. Depending on the architecture of a particular system, coverage may include the entire Earth, or only specific regions.
The mobile equipment, also known as a terminal, varies widely. Early satellite phone handsets had a size and weight comparable to that of a late-1980s or early-1990s mobile phone, but usually with a large retractable antenna. More recent satellite phones are similar in size to a regular mobile phone while some prototype satellite phones have no distinguishable difference from an ordinary smartphone.Satphones are popular on expeditions into remote areas where terrestrial cellular service is unavailable.
A fixed installation, such as one used aboard a ship, may include large, rugged, rack-mounted electronics, and a steerable microwave antenna on the mast that automatically tracks the overhead satellites. Smaller installations using VoIP over a two-way satellite broadband service such as BGAN or VSAT bring the costs within the reach of leisure vessel owners. Internet service Satellite phones have notoriously poor reception indoors, though it may be possible to get a consistent signal near a window or in the top floor of a building if the roof is sufficiently thin. The phones have connectors for external antennas that are often installed in vehicles and buildings. the systems also allow for the use of repeaters, much like terrestrial mobile phone systems.
In some countries such as Burma, possession of a satellite phone is illegal.Their signals will usually bypass local telecoms systems, hindering censorship and wiretapping attempts. In Australia, residents of remote areas may apply for a government subsidy for a satellite phone.

The SG-2520 smart phone will be commercially available soon in this year, with the Company planning to sell 70,000 units in 12 months. The SO retails around $725 and the SG is expected to sell at about $925.
The SO-2510 is a satellite only version designed for those requiring mobile connectivity in areas beyond terrestrial networks. At a mere 130 grams, it is loaded with features such as GPS, a high-resolution colour screen, enhanced memory, polyphonic ringtones, USB connectivity and multi-language support.
At 170 grams, the SG-2520 smart phone is a satellite tri-band phone that provides connectivity on GSM mode in all five continents. It has all the features of the SO-2510 plus a built-in camera and advanced streaming media capability. It is enriched with GSM 900, 1800 and 1900 MHz capabilities, runs on Windows-based operating system and supports Java. It also supports more than 10 languages.
