Geostationary satellite phones satellite phones used against civiliansAlthough satellite phones can be used for geostationary orbit connecting the world with only three or four satellites, the most popular civilian system is Inmarsat. Geostationary satellite phone requires an antenna system for reception and transmission of signals wide. This makes the entire system and affects inappropriately high mobility and ease of use, very harmful. Inmarsat satellite phones civilians such is very comfortable to use and does not require a system of large antenna. However, each hand satellite phone system suffers from a serious disadvantage that need a clear relationship with the sky and can not be used inside a building. In this case, the requirement will be to the external antenna and makes the whole process very heavy and expensive.
Satellite phones technology using Low Earth OrbitThese satellite phones have the rare advantage of covering the wireless world without gaps. The satellites are in low Earth orbit around the Earth at a very high speed, but at low altitude with an orbital path about 90 minutes. The orbit altitude you are somewhere between 600-1150 km. The two systems are original Gobalstar LEO Iridium and could not be popular.The models of satellite phonesSatellite phones have been very popular in the movies and shows. They are available in different styles and come from different brands. The most popular ones are Globalstar, Iridium and Inmarsat. A potential user is not always buys satellite phones for rental are also available. Satellite phones can also be purchased online order. Most providers also have the delivery system the same day or at home, as preferred by customers. They offer attractive plans to get a customer as a deposit, extra battery free and unlimited minutes and no packaging, fast shipping, and more.
An example is renting international cell phone package offered by some, that provides connectivity to 130 countries with payment pulse rate of 89 cents to $ 1.69.Transition commercial consumer useAt the beginning of the new millennium, satellite phones are still making good progress and most of the vendors were fighting for self-sufficiency. The most important behind a state of affairs was due to pay the high cost and high frequency pulse payable. For example, the cost of mobile phone Globalstar around $ 1,200 and pulse rate to pay is $ 2.49 per minute. Inmarsat has provided a bulky suitcase set at $ 3,000 to $ 10,000. Therefore, initially, users of satellite phones are the government and big business houses. They used satellite telephony services to remote areas close to not having other means of communication. Even rental rates in 2001 were a little friendly $ 159 per week with call charges $ 3.99 per minute. However, in the last five years, there has been a radical change in this area.
The first satellite phone system was popular service provided by Iridium with a cost of $ 1,995 or even was available in the rental of $ 19.99 per month. The payment of reasonable pulse was $ 1.99 and the prices were much lower than previous charged for satellite phones.The initial stages of the transition to commercial satellite phones based on consumption took place in 2001 with the launch of the Iridium data services worldwide. He planned to compose a rate of 2.4 kbps and direct information flow through a 10 kbps Internet. It also introduced a package with a pulse of 99 cents per minute surcharge fee. And the most important development is the prepaid phone service to a pulse average of $ 1.09 per minute. The satellite phone service, originally open only for government became open to private clients. Today, providers such as Globalstar satellite reduce costs 80% of the cost of telephony in 2001.The user scenarioHowever, so far largest user of satellite phones are the military. Today offers Globalstar satellite phone at $ 645, and games are available at a lower price of $ 599. 2006 voice and high data rate Inmarsat. But the cost exceeds $ 1650, with the advantage of providing services heretofore unavailable BGAN.
This technology eliminates the need for terminals above a customer cost around $ 8,000. The advantage of this technology is clear voice and digital data transfer at high speed. Gradually, the popularity of mobile satellite and began to increase average revenue collection marked increase of 30% of the affected industries. With a 60% drop in the satellite phone rental, power consumption is multiplied by virtual million. The growing awareness among potential customers about the ease of voice and data transmission via satellite service has led to a growing industry of satellite phones in the United States. Growth was showing an upward trend over the last five years.The dawn of a new era in wireless communicationsRecently, the Federal Communications Commission (FCC) has granted authorization to provide ancillary terrestrial component (ATC) Globalstar. Accordingly, Globalstar is permissible to implement ATC base stations and mobile terminals. Globalstar now offers a dual-mode light with two modes of satellite and ATC. It uses 11 MHz of radio frequencies satellite 1,6 / 2,4 GHz for land mobile service. The advantage is that it allows the phone to operate in dual mode. Inside a car the entire phone will work on land or in ATC mode and work out in satellite mode. The first modified dual mode demonstration was held in New York in 2002.
Although the telephone infrastructure is disrupted, the satellite phone system can provide smooth communication. However, the Globalstar satellite phone system is not without limits. It can be used as an ordinary cell phone in a building or in a vehicle. The inventors are looking for a mobile phone that has no dead spots and works everywhere. Another requirement in the current circumstances is adding broadband data and multimedia to the transparent layers of wireless communication. However, it is only in the distant future, when the current service satellite phone should be used outdoors with at least 80% of the sky view or the use of an external antenna.The satellite phone use different from each otherNormally you need the same type of satellite phones throughout the group to communicate properly. There can be no use of two types of satellite phones in the frame. Otherwise, the communication system is an indirect way. For example a phone call from a telephone Iridium Globalstar send the call to the first constellation Iridium and Iridium gateway. Then it will go through a landline to the Globalstar gateway.
Sometimes the required gateway is altered and there is difficulty in communication. Globalstar has a constellation of 48 satellites in low Earth orbit. It covers 120 countries and one of the best transmission quality. Iridium is a constellation of 66 satellites in low Earth orbit and global coverage. Inmarsat mobile devices using geostationary satellites. This application is very simple and easy to use.Satellite phones for emergenciesIn these days of hurricanes, terrorism and power outages, everyone should be prepared to respond to unforeseen emergencies. Preparation is essential for local phones tend to die in the time it is needed in an emergency. There is no problem with satellite phones. Satellite phones are not subject to the whims of nature and can be used anytime anywhere with ease and can have real value in the worst emergencies.Rental mobile satellite satellite phone sales. When you need to communicate in that mobile phones can not call for more details on satellite phones.
Our satellite phones have SIM card already installed. Instantly, the phone is able to communicate and the SIM card also contains the phone number and all the brains. Rates can be extremely low using this system. For example, free of all countries, day and night, always calls. Need a common cell phone instead of a satellite phone? We have the service and more than 160 countries worldwide. 99% of all SIM cards have free incoming calls from any country as long. Import duties, for example, the United Kingdom, the United States U.S. $ 0.08 per minute. No subscription, no contract, no verification of credit card, no bills. Pre-paid always means no minimum contract, no obligation. You only pay for the calls.
