RadioWORKS app for iPhone and iPad

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, band classification, propagation methods, common transmitter configurations, etc. View a graphical 2D representation of line of sight coverage between two latitude / longitude points, including compensation for TX/RX height, adjustment for Earth curvature, and first Fresnel zone calculation. 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. Contains path-loss calculators including Free-Space, ITU Terrain, Hata Urban, Hata Suburban, Hata Open Area, COST 231 Hata Extended, Weissberger, and Empirical COST-Walfisch-Ikegami (COST 231 Empirical) Line-of-Sight (LoS) and non Line-of-Sight (n-LoS) models. All path loss and distance / power change prediction calculations can also be displayed graphically. Calculate antenna lengths or frequencies. Calculate the beam width, gain, and far-field distance of a dish antenna.

RadioWORKS requires an iPhone running iOS 9.0 or later.
