Trachewsky describes wave modulation as "deliberately introducing correlation between signals -- which sounds like a bad thing but is not -- [because] dependence between transmitted instances and time [helps] shape and compress spectrum effectively [and] it isn't distorted much by non-linear elements," he said.
Part of the innovation is a novel receiver design "that pulls apart [the] dependency [between transmitted data sets] and extracts the information stream," he said. "You have to do it exactly right not to increase capacity -- that’s part of it too," he added.
In its press materials, Magnacom described its technology as a "multi-dimensional signal construction operating at the Euclidean domain... breaking the orthogonality of signal... to increase capacity and provide an optimal handling of nonlinear distortion." It "uses nonlinear signal shaping... digitally at the receiver side," it added. The approach is backwards compatible with QAM.
A big hurdle for Magnacom is that new communications technologies such as modulation schemes need to be standardized before they are deployed. The process can take many years and force disclosures that help competitors catch up.
Thus Magnacom is likely to try to get a foothold in significant but smaller markets such as point-to-point microwave backhaul or satellite links. Here what Trachewsky called "the standards burden" is not so great.
Ultimately the big win for Magnacom is to get cellular and WiFi networks using its approach. But that will take longer efforts with groups such as 3GPP and the IEEE and involve competing -- or partnering -- with giants such as Qualcomm, Broadcom, and others.
"The real challenge is finding the right combination and sequence of market entry points," said Trachewsky. "Yossi has good plan and is aware of these challenges," he said of Cohen.
