Geostationary satellite telephones to civilian use satellite mobile phone satellite phones

Although combines satellite phones for geostationary orbit, the whole world with only three or four satellites can be used is the most popular civilian Inmarsat satellite phones system. Geostationary satellite phone requires a large antenna for reception and transmission of signal. That makes the whole system unwieldy size and affects the mobility and ease of use, very detrimental. Civilian Satellite phones such as Inmarsat, is quite handy to use and does not require such a large system of the antenna. However, each hand-held satellite telephone system suffers from a major drawback that they become unusable, a clear connection with the sky and have a building. Here is the requirement that the external antenna can be and it makes the whole process very time-consuming and costly too.

Satellite phones with Low Earth Orbit technology line break line break line break line break these satellite phones, a rare advantage to the world without wires and without gaps are. Low Earth orbit satellites around the earth to go on a very high speed, but at lower altitude with an orbital period of about 90 minutes. The height at which these satellites move somewhere between 600 to 1,150 kilometers. The original two-LEO systems are Iridium and Gobalstar could not become popular.

Satellite phones model line break line break line break line break satellite phones were very popular in the movies and stage shows. They are available in various models and come from different brands. The most popular are Globalstar, Iridium and Inmarsat. A prospective user does not always have a sale, because satellite phones on rental also available. Satellite phones can be purchased through online ordering. Most of the vendors and the system of same day delivery or door, as preferred by the customer. They also offer attractive free plans for customer service like no deposits, an extra battery, and unlimited use with no bundled minutes, fastest delivery, and to win many more. An example is the international cell phone service package from a few available, the connectivity delivers to 130 countries with a pulse frequency of payment of 89 cents to $ 1.69.

Transition from commercial consumers use

At the beginning of the millennium, satellite phones to be a major move forward and most vendors were to fight for self-sufficiency. The most relevant reason behind such a state of affairs was to pay high costs to be paid and high pulse rate. For example, the Globalstar handheld phone costs about $ 1,200 and to pay the pulse rate was $ 2.49 per minute. Inmarsat was the provision of a bulky suitcases at $ 3,000 to set $ 10,000. Therefore, the first users of satellite phones, the government and big business houses were. They used the satellite phone services in remote areas with no other means of communication approach. The rental costs in 2001 were an unfriendly $ 159 per week with call charges at $ 3.99 per minute. But over the past five years there has been a fundamental change in this area. The first popular service provided by satellite phone from Iridium system was priced at $ 1,995 and the same was found to rent at $ 19.99 per month. The pulse rate of payment was a reasonable $ 1.99 and these rates were much lower than previously charged rates for satellite phones.

The first steps in the transition from consumer-based commercial satellite phones took place in 2001 with the launch of Iridium World Data Services. It provided for dial-up throughput of 2.4 kbps and direct Internet data throughput at about 10 kbps. A package with a pulse rate payment of 99 cents per minute, was also introduced. And the most important addition was the pre-paid phone service at an average heart rate of $ 1.09 per minute. The satellite telephone service which will initially open only to the government, is now open for private clients. Today, providers such as Globalstar satellite phone, the cost by 80% of its costs in scenario

However 2001.

The users, the largest user is reduced to this day of satellite phones to military. Today, Globalstar satellite handheld phone at $ 645, and are set at a lower price of $ 599. The 2006 has voice and Inmarsat high-speed data service. But the costs are higher at $ 1,650, with the advantage that it provides for BGAN services are not available until now. This technology eliminates the need for pins, which formerly cost a customer to use nearly $ 8,000. The advantage of this technique is clear, digital voice and data transmission at high speed. Gradually began to increase the popularity of satellite phones and marks the average tax collection at 30% increase for the industries involved. With a 60% fall in rents for satellite phones, consumer power has multiplied into virtual million. The growing awareness among potential customers about the simple transmission of voice and data over the satellite service has led to the further growth of satellite phones industry in the United States. The growth of what has been a rising trend for the last five years.

Dawn of a new era in wireless communications

Recently the Federal Communications Commission (FCC), has the power to grant ancillary terrestrial component provide services (ATC) for the benefit of Globalstar. As a result, the right to set up Globalstar ATC base stations and mobile devices. Globalstar offers today a small, lightweight dual-mode mobile phone with both satellite and ATC modes. It uses 11 MHz of its 1,6 / 2,4 GHz satellite radio frequencies for terrestrial wireless services. The advantage is that it can operate the phone in dual mode. In a car phone in the ATC or terrestrial mode to work outside and it will work in the satellite mode. The first modified dual-mode demonstration was done in New York in 2002. Even if the local telephone infrastructure is disrupted, the satellite phone system provide seamless communication. However, the Globalstar satellite phone system is not without limitations. It can not be used as an ordinary mobile phone into a building or in a vehicle. The inventors are now looking for a portable phone that works and has no dead spots anywhere. Another requirement in the present circumstances is to add broadband data and multi-media applications, to provide a seamless layers of wireless communication. But this is in a distant future, while the current satellite phone service must be outdoors at least 80% view of the sky or the use of an external antenna.

Use of satellite phone to communicate with each other differently other

Ordinarily you the same kind of satellite phones in all the right group together. There can be no use of two types of satellite telephones part. Otherwise, the system of communication would be in a round about Sun For example, calling a Globalstar phone is sent from an Iridium phone to the call of the first Iridium constellation and then to an Iridium gateway. Then it will go through a landline connection to the Globalstar gateway. Sometimes the required gateway is disturbed and experiencing difficulties in communication. Globalstar has a constellation of 48 satellites in low earth orbit. It covers 120 countries and has one of the best transmission quality. Iridium is a constellation of 66 low earth orbiting satellite and a planet gear coverage. The use of mobile devices with Inmarsat geostationary satellites. This structure is very simple and user-friendly phones for friendly.

Satellite emergencies

In in these days of hurricanes, terrorism and power outages, everyone should tackle in readiness, any unforeseen emergencies. The preparation is very important because the local phones tend to die down only when needed, most have in an emergency. There is no such problem with satellite phones. Satellite phones are not subject to vagaries of nature and can be used at any time, any where with ease and this can have a real added value during the worst emergencies.
