The Wireless Power Calculator is a web-based tool to estimate the amount of RF power available at the receiver, and the amount of RF power that is converted to DC.
Powercast’s Wireless Power Calculator
This calculator is based on Friis equation and is intended for estimating or planning purposes only. For more information or to discuss your custom application, contact us.
Powercast Transmitter EIRP:
Transmission Power Units:
Tx/Rx Gain Units:
Distance between the Tx and Rx antennas.
*Distances below meters could generate inaccurate results.
Friis Equation Output:
RF-to-DC Conversion Efficiency.
Gains for Common Antennas
Dipole antenna 1.6 W/W
Patch antenna 4.0 W/W
F antenna 1.6 W/W
If using a custom transmit(Tx) or receive(Rx) antenna, refer to the datasheet(s) of that antenna and be sure to use correct units when entering the fields above. If you are using a Powercast transmitter or receiving antenna, correct gain and transmit power are automatically populated.
