### How to use Friis Transmission Equation Calculator?

Step 1 - Enter the Transmitter Power (Pt)

Step 2 - Enter the Receiver Gain (Gr)

Step 3 - Enter the Distance (d)

Step 4 - Enter the Frequency (f)

Step 5 - Enter the Wavelength (λ)

Step 6 - Calculate Recieved Power (Pr)

## Friis Transmission Equation Calculator Formula:

### Pr=Pt × Gt × Gr × $(c/(4 × π × d× f))^2$

### P(dB)r=Pt + Gt + Gr + (20 × log(c/(4 × π × d × f)))

Where,

Pr = Received Power

Pt = Transmitter Power

Gt = Transmitter Gain

Gr = Receiver Gain

d = Distance

f = Frequency

P(dB)r = Received Power in dB

c = Speed of light (equal to 3 * $10^8$ m/s)
