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, divide the result by 1.66)



  This calculator provides an estimated range between the receiver's antenna and the transmitter's antenna free of any obstacle. There are many variables that can drastically increase or drop the range such as, placement of the antennas, type of the antennas, other electronics around, even the area where it will be used.
