Discover the History of Satellite Telephones

A satellite telephone may be described as a cell phone providing service anywhere literally. They are way too expensive compared to the regular mobile phones. However, their main functionality lies in allowing users to make calls from anywhere irrespective of the time and independent of cell phone services in the area.

The Beginning:

International Mobile satellite Organization was the First Company to initiate such services way back in the year 1979. However, the agency was primarily created for providing communicational support to the Marines.

How it Works:

A few Satellite telephone networks use a conglomeration of satellites orbiting in a geosynchronous pattern. This helps the network offer an all encompassing coverage using three to four satellites only. The alternative method includes placing satellites in the low earth orbit. In this case there would be a greater number of satellites required, amounting to a dozen even. Iridium- the famous <a href="http://www.cellhire.co.uk/">mobile phone UK</a> Company applies this mechanism.

How it differs from Cell Phones:

It connects itself to a particular satellite for triggering communications. It goes without saying that they are significantly different from the mobile phones which remain primarily restricted to land based or local service towers only. Although cell phones fall back on satellites often for achieving broader communication networks, they cannot dial the satellites directly as a Satellite telephone can

The Flipsides:

The satellite telephone microwave transceiver often registers bad service conditions indoors. This is where cell phones score higher. It has to be kept in mind that networks relying on geosynchronous satellites account for a significant delay in transmission. The main reason is the location of the satellites several miles into space which, in turn, requires every signal to travel 44,000 miles roughly across phones. The satellite telephone comes with a huge price tag. Both the device and the service time tend to be costlier than the cell phones. In fact, making calls to a <a href="http://www.cellhire.co.uk/">Satellite telephone</a> is expensive too. If a person has enough money to buy satellite gadgets, the associated costs fade into oblivion.
