What is a satellite phone?
satellite phone is a phone that can be mobile or fixed in one place. Although it works similarly to a ground mobile phone, the satellite phone relies on the satellites in the atmosphere to hand over the communication from one person to another. It is most often used in remote places where ground telephone lines and cell towers are not present, for example in undeveloped countries or on the ocean ship. It can also be useful if other forms of communication are not available for natural disasters such as earthquakes, hurricane, tidal wave or other devastating events.
If the satellite phone is portable, it looks similar to a modern mobile phone or smartphone. These phones are most commonly used when someone travels to an area where it is difficult to find a typical signal of a mobile phone. For example, someone traveling in distant areas of Central or South America can consider a useful satellite phone. In an alternative, a satellite phone that Jena's fixedThe wall, for example on a ship or in a country village, is much more voluminous.
Some satellite telephone services provide complete coverage of all areas of the world, while others provide regional coverage. Most of the services are divided between their use of geosynchronous satellites and low -country orbit satellites. In addition, some countries, such as North Korea, do not allow residents or visitors to own satellite phones. These countries may regulate or even block satellite phones from signal transmission.
geosynchronous satellites are located at a certain height in the atmosphere. These satellites travel at the same speed as the rotation of the Earth. As a result, it seems that satellites do not move. As a result, few satellites are needed. The disadvantage may be a noticeable delay of the signal and shaking voice communication using these satellites, a pleasant communication.
satellThe low -ground levels are much lower in the atmosphere than geosynchronous satellites. Because they are lower to the ground, more satellites are required to fully cover. On the other hand, the signal is less delayed and communication is often clearer.
satellite phones can range from slightly price to quite expensive. Usually there are also costs for each minute of use. In addition, there are some plans in which the user can pay for several minutes before using them, saving some money. Some satellite phones offer Internet connection in addition to the ability to provide vocal communication. Although most people will not use a satellite phone instead of a ground phone or mobile phone, it may prove to be useful when the least expected, causing irrelevant costs.
