All About Satellite Phones

A satellite telephone is nothing but a type of cell phone that, unlike any conventional mobile phone, provides service almost anywhere. It's usually more expensive than cell phones as they provide an important capability of receiving and making telephone calls at any time and from anywhere, independent of a local cell phone service or geographical boundaries. best free satellite phone

Identification

A satellite telephone connects to a satellite in orbit for achieving communication. This is different from a conventional mobile phone that connects to a local and land-based service tower. Though cell phone networks use satellites for achieving a larger communication radius, mobile phones don't directly dial to these satellites.

Features

Several satellite telephone networks use an interconnected network of satellites in the geosynchronous orbit that enables the network to attain global coverage with only three to four satellites. The other method of satellite telephone communication is to place the satellites in the low-earth orbit. This, however, requires more number of satellites for achieving global coverage. They can be smaller nevertheless for reducing launch costs. free satellite phone

Effects

The microwave transceiver of a satellite phone gives notoriously poor service indoors. In this regard, their reliability and performance is worse than a cell phone. Moreover, the networks that depend upon geosynchronous satellites usually suffer from a transmission delay of over a second. This is because satellites are positioned at about 23,000 miles in space. This means that every signal has to travel approximately 46,000 miles from one handset to the other. Besides, a satellite phone handset is more expensive than a mobile phone. In fact, both the handset and the service are priced much higher than conventional cell phones. Calling satellite phones from landlines or mobile phones is also very expensive although this hardly costs anything to the satellite phone owner. Satellite phones, however, should be the preferred device if you want reliable communication in remote areas where cell phone networks are weak.
