FAQ

What is RF Link Calc used for?

RF Link Calc is a numerical calculation tool designed for radio engineers. It helps model the characteristics of an RF link, including wireless internet (WiFi) links, to compute parameters like maximum distance, required transmitter power, or gain margin.

What parameters can I input into RF Link Calc?

You can input frequency (MHz), transmitter power (dBm), transmitter antenna gain (dBi), transmitter cable loss (dB), distance (miles or kilometers), receiver sensitivity (dBm), receiver antenna gain (dBi), and receiver cable loss (dB). The app then calculates the remaining values.

Does RF Link Calc calculate EIRP and ERP?

Yes, the EIRP/ERP Calculator within RF Link Calc computes the Effective Isotropic Radiated Power (EIRP) and Effective Radiated Power (ERP) in both watts and dBm, based on transmitter power and antenna gain.

What units does the Field Strength Calculator in RF Link Calc support?

The Field Strength Calculator converts between V/m, dBuV/m, dBuA/m, pT, dBpT, Tesla, Gauss, A/m, mW/cm², and W/m².

What is the price of RF Link Calc?

RF Link Calc is a paid application priced at $2.99.

On which devices can I use RF Link Calc?

RF Link Calc is supported on iPhone, iPad, and iPod devices.

How often is RF Link Calc updated?
