This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Line of Sight - (Measured in Meter) - The Line of sight is a type of propagation that can transmit and receive data only where transmit and receive stations are in view of each other without any sort of an obstacle between them.
Height of Receiving Antenna - (Measured in Meter) - The Height of receiving antenna is the height at which receives radiofrequency radiation and converts it into electric currents in an electric circuit connected to the antenna.
Height of Transmitting Antenna - (Measured in Meter) - The Height of transmitting antenna is defined as the height of the radiation center of the antenna above the average terrain.
STEP 1: Convert Input(s) to Base Unit
Height of Receiving Antenna: 70 Meter --> 70 Meter No Conversion Required

Line of Sight Formula

Line of Sight = 3577*(sqrt(Height of Receiving Antenna)+sqrt(Height of Transmitting Antenna))
LOS = 3577*(sqrt(hr)+sqrt(ht))

How does a definite range is formed?

A way of propagating radio waves is through space waves. A space wave propagates from the transmitting antenna to the receiving antenna in a straight line of sight. Because of straight line of sight propagation at a point this wave is blocked because of the curvature of earth's surface. So, we have a definite range for this type of wave.

What are the other types of radio transmission/

We have other types of radio wave transmissions also. In ground wave transmission we should have an antenna with size comparable to the wavelength. In sky wave propagation we use the ionosphere to reflect the radio waves.

How to Calculate Line of Sight?

Line of Sight calculator uses Line of Sight = 3577*(sqrt(Height of Receiving Antenna)+sqrt(Height of Transmitting Antenna)) to calculate the Line of Sight, The Line of Sight formula is defined as the imaginary line between an observer and the target. In communication, line of sight is the direct path from a transmitter to the receiver and the obstructions that may fall in that path. Some forms of wireless transmission are completely blocked if anything comes between the transmitter and receiver. Line of Sight is denoted by LOS symbol.

How to calculate Line of Sight using this online calculator? To use this online calculator for Line of Sight, enter Height of Receiving Antenna (hr) & Height of Transmitting Antenna (ht) and hit the calculate button. Here is how the Line of Sight calculation can be explained with given input values -> 50161.9 = 3577*(sqrt(70)+sqrt(32)).

FAQ

What is Line of Sight?
The Line of Sight formula is defined as the imaginary line between an observer and the target. In communication, line of sight is the direct path from a transmitter to the receiver and the obstructions that may fall in that path. Some forms of wireless transmission are completely blocked if anything comes between the transmitter and receiver and is represented as LOS = 3577*(sqrt(hr)+sqrt(ht)) or Line of Sight = 3577*(sqrt(Height of Receiving Antenna)+sqrt(Height of Transmitting Antenna)). The Height of receiving antenna is the height at which receives radiofrequency radiation and converts it into electric currents in an electric circuit connected to the antenna & The Height of transmitting antenna is defined as the height of the radiation center of the antenna above the average terrain.
