Link Power Budgetting : Calculation/Measurement Of Transmit Antenna Gain
2.Calculation of Transmit antenna gain 1. Antenna diameter: Diameter of parabolic reflector antenna is referred as antenna diameter. It is denoted by 'D' 2. Antenna efficiency: Antenna efficiency is the ratio of input power to the radiated power of the antenna. It is denoted by 'h'. The value of 'h' lice between 0.55 to 0.73. 3.Antenna gain GT: The isotropic power gain of the antenna, GT, is defined as the power density in the maximum direction, denoted here by PD,to the power density archived by a 100% efficient isotropic radiator.

Satellite Phone : Functioning/Working Of Satellite Phone
There are three types of satellite communication systems which differ in terms of orbit and signal strength. Low earth orbit (LEO) satellites have small area coverage and they orbit below about 1,800 miles from the earth's surface. Medium earth orbit (MEO) satellites peak at 9,000 miles and are commonly used in navigation systems such as GPS Geosynchronous earth orbit (GEO) satellites at 22,300 miles and they are positioned over the equator.

Satellite Phones - Review
A satellite phone is a phone that uses satellites for communication (receiving and sending signals) instead of terrestrial lines. Ideally, these phones enable communication anywhere around the world irrespective of location whereas normal cell phones require proper terrestrial network coverage to enable communication.
