RF Line-of-Sight provides radio path information for mapping long distance SCADA radio communications by using antenna height and topography.
Those skilled in the art will appreciate that an antenna lobe is the volume of space within which RF signals can be detected and coupled to a receiver connected to the pencil beam antenna or within which RF signals can propagate after being transmitted by a transmitter connected to the pencil...

Line-of-sight (LOS) link planning condition has been observed to have effects on the atmospheric factor which cause crucial signal loss. The main objective of the planning was to improve a set of a link using point to point condition to assist the performance in emerging its strategy for han...
In this paper, we propose to use spatial modulation (SM) and the generalized spatial modulation (GSM) MIMO schemes in indoor line-of-sight (LOS) millimeter-wave (mmWave) communication at 60GHz. SM/GSM are known but only at low-GHz frequencies where the channels are typically rich scattered...

In obtaining the radar horizon equations, it is common practice to assume a value for the Earth's radius that is 4/3 times the actual radius. This is done to account for the effect of the atmosphere on radar propagation. For a true line of sight, such as used for optical search and ...
