The satellite phones which uses the satellites from low earth orbit are called Low Earth Orbit Satellite Phones. The most and the important advantage is seamless coverage around the world regardless of any hindrances. Since the satellites are not stationary, so they need to fly the whole orbit. In this service at least one satellite is with line of sight in any of the region in the world. Two such companies were launched in the year 1990 but went into bankruptcy and now owned by new owner who bought this paying a fraction of money of the original cost.Now they are planning to launch replacement constellation of satellite supporting higher bandwidth. Data transfer seed is like 2200 bits/sec and 9600 bits/sec using satellite phone hand sets.
