What’s spectrum?
Where’s the spectrum constraint?
Spectrum is a finite resource since there are only so many radio frequencies – 30kHz to 300GHz – and even fewer that are productive for telecommunications – between 1GHz and 6GHz. 5G technology is slowly moving into the millimeter wave range – 30GHz to 300GHz – but at these frequencies signals can’t go through obstacles like foliage, walls, or even your hand blocking the antenna, a characteristic that ultimately limits millimeter wave applications. This is all to say: it will only get harder to redirect spectrum toward telecommunications to meet the ever growing demand for data. At some point we need to start looking at using our existing spectrum more efficiently rather than using new spectrum inefficiently.
In comes Eridan.
Our MIRACLE module acts as a hyper efficient radio for telecommunication needs. And by efficient, we mean power-efficient and spectrum-efficient. The MIRACLE allows 2-4x more data to be encoded into the same amount of spectrum, reducing the need for new spectrum allocation.
We do it by producing ultra-precise signals with minimal noise with which we can encode more data utilizing QAM, quadrature amplitude modulation. Higher order QAMs contain more data for the same amount of spectrum usage, but signal precision requirements grow exponentially with modulation order. While current technology can achieve 64-QAM resulting in 6 bits encoded, Eridan has achieved 16384-QAM resulting in 14 bits encoded (IEEE, Keysight).
