(a)Transmitter Power (b)Path loss Free Space Path Loss Calculator. Pasternack's Free Space Path Loss Calculator calculates the loss (in dB) between two antennas where the gain, distance and frequency are known. Bookmark or "Favorite" this page by pressing CTRL + D. Free Space Path Loss Calculator The free space path loss is the loss in signal strength of a signal as it travels through free space. This value is usually calculated by discounting any obstacles or reflections that might occur in its path. - Calculates the Path Loss (attenuation in dB) in a free field like space communications. - Also the distance can be calculated if the Path Loss is given (in dB).

Path Loss and Shadowing may not be considered to be a part of Fading in narrow sense, but it can be considered as a factor causing the fading in wider sense. Understanding or Modeling the path loss is not that difficult. You may see a mathematical model which you were faimilar with in your high school math. Percentages may be calculated from both fractions and decimals. While there are numerous steps involved in calculating a percentage, it can be simplified a bit.
I have put down a 1/4 wave radial for 20 meters and not enough current to light a flashlight bulb connected to main ground at 100w. Thanks Tim Wa9eeh@yahoo.com

RSSI & FREE SPACE PATHLOSS CALCULATOR. TRANSMITER: RECEIVER: CABLES: DISTANCE: RESULTS: Tx Power (select unit) Rx gain (dBi) Losses (dB) From Tx to Rx. RSSI This calculator is an approximation of the actual path loss you will encounter in your system. It does not take Fresnel zones into the calculation and is a representation of transmitter to receiver in a free field environment with no obstructions.

- Substract the field attenuation from the TX power in dBm to get the power in dBm at the RX input. EXAMPLE of Hata model path loss calculator: INPUTS : Frequency = 900 MHz, BS antenna height = 100 m, MS antenna height = 2 m, Distance = 4 Km OUTPUTS: a(hm) = 1.29 dB, Path loss = 137.05 dB . Hata model path loss formula. Following Hata model path loss formula is used in this calculator to calculate path loss.

A cable loss of 2 dB is considered, which is compensated by assuming a masthead amplifier (MHA) that introduces a gain of 2.0 dB. An RX antenna gain of 18.0 is assumed considering a 3-sector macro-cell (with 65-degree antennas). In conclusion the maximum allowed path loss becomes 163.4 dB. small area average (shadowing), and variations over very large distances (path loss). Path loss prediction plays a crucial role in determining transmitter-receiver distances in mobile systems [1]. This thesis aims at describing various accurate path loss models that are used in rural and urban areas.
