WebTo calculate this we need to first work out the distance l through the earth to the center point . We'll need this angle θ in degrees first of all. Given that d is a fraction of the earth's diameter r, then θ is simply calculated with the … Earth bulge. In telecommunications, Earth bulge refers to the effect of earth's curvature on radio propagation. It is a consequence of a circular segment of earth profile that blocks off long-distance communications. Since the vacuum line of sight passes at varying heights over the Earth, the propagating radio … See more Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves travel in a direct path from the source to the receiver. Electromagnetic transmission includes … See more Low-powered microwave transmitters can be foiled by tree branches, or even heavy rain or snow. The presence of objects not in the direct line-of-sight can cause diffraction effects … See more The radio horizon is the locus of points at which direct rays from an antenna are tangential to the surface of the Earth. If the Earth were a perfect sphere without an atmosphere, the See more • • Article on the importance of Line Of Sight for UHF reception • Attenuation Levels Through Roofs See more Although the frequencies used by mobile phones (cell phones) are in the line-of-sight range, they still function in cities.
