In the above calculation, the free space patch loss calculator takes in to account the gain on both the receiving and transmitting antennas. The gain of the antennas offsets the loss by a certain decibel value. If you ignore the gain at either end i.e the transmitting and receiving end, ...
Free Space Loss Calculator Free Space Loss is the power loss of a radio signal as it travels through free space. Free Space loss calculation helps RF designers estimate the receive power strength for a given transmitter power. It helps determine the line of sight distance. Free space loss de...
Calculation Distance: KilometersMetersCentimetersMilesYardsFeetInches Frequency: GHzMHz Transmitter Gain (dB): Receiver Gain (dB): Result: Free Space Path Loss (FSPL) calculations are often used to help predict RF signal strength in an antenna system. Loss increases with distance, so understanding ...
The free-space path loss,L, in decibels is: L = 20log10(4πR/λ). This formula assumes that the target is in the far-field of the transmitting element or array. In the near-field, the free-space path loss formula is not valid and can result in a loss smaller than 0 dB, equiva...
Free Space Path Loss (or FSPL) represents the amount of energy that a given radio wave loses as it travels through the air away from its source. Understanding FSPL will help us understand how far a Wi-Fi signal can go. It is also widely used by Wi-Fi survey tools to predict Wi-...

Free space path loss for THz communication is discussed. Molecular absorption mainly caused by water vapor is a major effect in terahertz propagation in the atmosphere. Both experimental and theoretical results are also discussed using the ITU models and the am model. A simplified model for molecula...

The atmospheric loss Lm is approximately 2.1 dB for 0.5 m wireless distance at 150 GHz. The free-space path loss 20 log(4πdf/c) equals approximately 70 [20 log•(4π•0.5•(150 × 109)/(3 × 108))~70] dB. The received power PR can be calculated ...
where f c represents the central frequency, P L m n L O S represents the LoS link pass loss, and P L m n ′ represents the free space path loss, defined as P L m n ′ = d 0 H 2 + q n U A V − q m A P 2 , where q n U A V represents the two-dimensional coord...
