Introduction Astrapi® is a pre-product company that will transform the core technology for the multi-trillion-dollar telecommunications industry. By introducing a fundamentally new form of signal modulation, called ‘Spiral Modulation’, Astrapi has opened the door to pushing spectral efficiency far beyond what was previously viewed as the theoretical limit. This can provide 2X or greater improvements … Read more

Astrapi® has introduced a ground-breaking technique for constructing and analyzing signals using sinusoidals with continuously-varying amplitude. Instantaneous Spectral Analysis (ISA) is a sharp break from the existing practice of representing signals as sinusoidals which have constant amplitude over some period of time. With ISA, it is possible to construct signals using only sinusoidals in a … Read more
