TM Technologies, a Tucson, Arizona-based communications technology firm, has announced that after several years of development, its patented TM modulation DSP method has completed validation testing by a renowned independent RF signals analysis lab, the company said.
Among the findings, the evaluating engineering team´s report stated, “Based on the doubling of the information rate within the confined channel, a two times improvement in spectral efficiency was observed as compared to the traditional QAM256 signal.”
Following these test results, an initial development and use license was negotiated with an affiliated carrier-grade telecom radio company for the integration of the TM waveform within its microwave backhaul radio links.
The resulting radio is planned to be capable of doubling 256-QAM data rates, or 16 bits per second per Hertz, at a noise level representative of 256-QAM alone. This calculates to an equivalent 65,536-QAM at a 256-QAM noise level, in short — representing one of the most efficient communications data methods to date. It is believed that the emplaced microwave radio link will be prepared, tested and available for customers in the 4th quarter of this year.
