Received Power Formula
The following formula is used to calculate the Received Power.
Pr = G * Pt / (f^2*d^2)
- Where Pr is the Received Power (watts)
- G is the antenna gain
- Pt is the transmitted power (watts)
- f is the carrier frequency (Hz)
- d is the propagation distance (m)
How to Calculate Received Power?
The following example problems outline how to calculate Received Power.
Example Problem #1
- First, determine the transmitted power (watts). In this example, the transmitted power (watts) is determined to be 12 .
- Next, determine the carrier frequency (hz). For this problem, the carrier frequency (hz) is measured to be 50 .
- Next, determine the propagation distance (m). In this case, the propagation distance (m) is found to be 86.
- Next, determine the gain. In this case, the gain is 2:1 = 2
- Finally, calculate the Received Power using the formula above:
Pr = G * Pt / (f^2*d^2)
Inserting the values from above and solving yields:
Pr = 2 * 12 / (50^2*86^2) = .00000129 (watts)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
antenna gain = 5
transmitted power (watts) = 105
carrier frequency (hz) = 3
propagation distance (m) = 14
Enter these given values into the calculator or above yields:
Pr =5 * 105 / (3^2*14^2) = .297(watts)
