Answer:
Line of sight (LOS): This a type of propagation
that can transmit and receive data only when the transmitter and receiving stations are in view of each other without any sort of obstacle between them.
This is also called space wave propagation or Friis transmission.
It is best suited for a frequency > 30 MHz
The Line of sight distance is calculated as:
LOS 4.12 [√h + √₂ km ---(1)
=
V
Calculation:
We are given h₁ = 100 m and h₁ = 16 m Putting on the respective values in Equation (1), we get:
LOS =
(4.12) (√100+ √16) km
LOS = (4.12) (19) km
LOS = 57.68 km
