Estimated Range Calculator for Wireless Video Transmitter - Receiver - Antennas


  *(Frequency) =

MHz    ( Example: 1.2 GHz = 1200 MHz or 5.8 GHz = 5800 MHz)

Z (System Impedance) =

Ohm

*(Transmitter output power in dBm) =

dBm dBW, mW Watt
(Example: 200mW=23dBm, 500mW=27dBm, 1000mW=30dbm)

*(Receiver Sensitivity) =

dBm dBW, mW, Watt

* (CP Transmitter Antenna Gain in dBi) =

dBi

Cables attenuation meter dB/m =

dB

* (CP Receiver Antenna Gain in dBi) =

dBi

Cables attenuation meter dB/m =

dB

    

(Power radiated in transmitting antenna)

. . . .

(Estimated distance between Tx and Rx Antennas)=

Miles  (For Kilometers, multiply the result in miles by 1.66)


  This calculator provides an estimated range between the receiver and transmitter line-of-sight and free of any obstacle. There are many variables that can drastically affect the range and overall performance of your wireless system such as; type of the antennas, quality of the antennas, placement of the antennas, other electronics around, even the area where it will be used at.
A good and clean installation using high quality antennas is a great start!
