A small Zürich-based firm, Decodio quickly established itself as an international Spectrum Monitoring (digital radio) leader by offering tailorable and agile solutions that exceed customer expectations. Through the analytical power of our flagship product, DECODIO RED , today’s Spectrum Professionals can quickly detect, decode, and localize various signals of interest, wading through today’s complex electromagnetic environment with ease.

Our software was created with scalability in mind, from small receivers up to installed facility monitoring systems. The individual software components run on a conventional PC and do not require specialized digital signal processing hardware.

Leveraging data from DECODIO RED , we developed DECODIO ORANGE to easily visualize complex spectrum data, DECODIO BLUE that stores data in a web accessible database, and DECODIO Localizer to triangulate signal emissions. For more information on how these software combine to overcome your hardest spectrum problems, please visit our Solutions and Markets pages.

While our roots are in decoding digital radio protocols (e.g. TETRA, P25, DMR, TETRAPOL), our softwares can be combined and configured to solve a wide range of problems inside today’s complex radio spectrum.
