PATH PROFILE USING MANUAL METHOD

Intelecommunication, apath profileis a graphic representation of the physical features of apropagationpath in the vertical plane containing both endpoints of the path, showing the surface of the Earth and including trees, buildings, and other features that may obstruct theradiosignal.A line-of-sight microwave link uses highly directional transmitter and receiver antennas to communicate via a narrowly focused radio beam. The transmission path of a line-of-sight microwave link can be established between two land-based antennas, between a land-based antenna and a satellite-based antenna, or between two satellite antennas. Broadband line-of-sight links operate at frequencies between 1 and 25 gigahertz (the centimetre wavelength band) and can have transmission bandwidths approaching 600 megahertz. A typical long-distance, high-capacity digital microwave radio relay system links two points 2,500 km apart by using a combination of nine terrestrial and satellite repeaters. Each repeater operates at 4 gigahertz, transmitting seven 80-megahertz-bandwidth channels at 200 megabits per second per channel.The maximum range of land-based line-of-sight systems is limited by the curvature of the Earth.Microwave radio transmission is commonly used inpoint-to-pointcommunication systemson the surface of the Earth, insatellite communications, and indeep space radio communications. Other parts of the microwave radio band are used forradars,radio navigation systems, sensor systems, andradio astronomy.
