ValoFSL is a high-precision Free Space Loss (FSL) solver built for RF engineers, wireless network technicians, satellite communications specialists, and telecom professionals. Perform quick, accurate propagation calculations with a sleek, distraction-free interface designed specifically for field and office use. Unlike basic single-purpose calculators, ValoFSL features a flexible multi-variable solver. Simply enter any two known values to automatically solve for the third—whether you need to determine signal attenuation, estimate maximum link distance, or identify the required frequency. KEY FEATURES • 3-Way Multi-Variable Solver: Seamlessly calculate Free Space Loss (dB), Distance, or Frequency given any two known parameters. • 100% Free & Private: Completely free with no ads, no in-app purchases, and zero user data collection. Your privacy and workflow are fully protected. • Wide Spectrum Coverage: Compute values accurately across frequencies ranging from kHz to millimeter-wave bands. • Flexible Unit Selection: Effortlessly toggle between metric and imperial distance units (meters, kilometers, feet, miles) and standard frequency units (kHz, MHz, GHz). • Precise Link Budget Support: Get immediate, accurate signal attenuation or path estimation to streamline your link budget modeling and coverage analysis. • Field-Ready Dark Theme: Built with high-contrast dark aesthetics for maximum legibility in low-light environments and direct sunlight. • 100% Offline Functionality: Performs all mathematical calculations locally on your device—no internet connection required for remote field deployments. • Lightweight & Clean: Zero telemetry bloat and no unnecessary device permissions—just pure engineering utility. IDEAL APPLICATIONS • RF & Wireless Engineering: Microwave backhaul design, cellular network planning, and point-to-point link evaluation. • Coverage & Distance Estimation: Quickly determine maximum allowable path distance for a target link margin. • Satellite Communications: Earth-to-space and space-to-earth path attenuation estimates. • WLAN & Private Networks: Outdoor Wi-Fi deployment and IoT coverage modeling. • Amateur Radio (Ham): Line-of-sight propagation analysis and antenna path verification. • Education & Research: Reliable reference tool for telecommunications and RF engineering students. ValoFSL combines mathematical rigor with flexible problem-solving, giving you a powerful, privacy-first RF tool wherever your work takes you.
