WiFi & Wireless tools
RF planning tools: free-space path loss, Fresnel clearance, EIRP limits, link budgets, channel plans and signal quality references.
EIRP Calculator
Calculate effective isotropic radiated power from transmit power, cable loss and antenna gain, and check it against regulatory limits.
Free Space Path Loss Calculator
Calculate free-space path loss for any distance and frequency, the theoretical floor that every wireless link budget starts from.
Fresnel Zone Calculator
Calculate first Fresnel zone radius and the clearance a wireless link needs at any point along the path, including earth curvature.
Wireless Link Budget Calculator
Build a complete point-to-point RF link budget: transmit power, antenna gain, cable loss, path loss and receiver sensitivity, with the fade margin that decides availability.
