RadioWORKS is a tool for calculating various items related to radio waves and radio wave propagation. Get detailed information about a frequency, such as the free-space wavelength, proper antenna lengths for common wavelength ratios, band classification, propagation methods, common transmitter configurations, etc. Calculate path loss using the Free-Space, Flat-Earth, ITU Terrain, Hata Urban, Hata Suburban, Hata Open Area, or Empirical COST-Walfisch-Ikegami (Also known as 'COST 231') non Line-of-Sight (n-LoS) and Line-of-Sight (LoS) mathematical models -- OR -- run the models backwards to get the matching distance for a given path loss value. Use the Distance and Power change prediction calculator to predict how a proposed transmitter power change, whether an increase or a decrease, will affect your usable range -- OR -- how a proposed range requirement change, whether an increase or a decrease, will affect your transmitter power requirements, while factoring in the signal decay rate observed in your current system. All path loss&distance / power change prediction calculations can also be displayed graphically. Context-sensitive help is available to guide with the usage of the various calculators. Additionally, all mathematical formulas used by the application are on display, including explanations and usage information.
