Wireless Link-Budget Calculator

Modified on Tue, 27 Oct 2015 at 11:22 AM

A Link-Budget is the total amount of power between a transmitter and receiver.

By taking this Link-Budget and factoring in the loss of power through free-space and other obstacles such as walls, it’s possible to roughly estimate the effective transmission distance and to gain an understanding of how various obstacles and other changes affect a signal.

Of course, wireless signal strength calculations aren’t really so simple, factors such as antenna directionality, design efficiency, reflection, scattering, diffraction and weather conditions all play a significant role.

The below calculator will provide an extremely-rough estimate of signal strength based on free-space proportion and obstacles only, but can be incredibly useful in helping to understand the affect various obstacles will have on the range of a wireless product.
