The formula to calculate the Received Power (Pr) is:
\[ Pr = \frac{G \times Pt}{f^2 \times d^2} \]
Where:
Received power refers to the amount of power that is received by the antenna in a wireless communication system. It is determined by factors such as the transmitted power, the antenna gain, the carrier frequency, and the propagation distance. Understanding received power is crucial for designing and optimizing communication systems to ensure reliable signal transmission and reception.
Let's assume the following values:
Using the formula to calculate the Received Power (Pr):
\[ Pr = \frac{G \times Pt}{f^2 \times d^2} = \frac{2 \times 100}{(2,000,000)^2 \times (100)^2} = 0.0000000025 \text{ watts} \]
The Received Power (Pr) is 0.0000000025 watts.
