Hardware Demonstration Validates Breakthrough Spectral Efficiency

A live RFSoC-based system achieving 233 bits/s/Hz at 12 dB SNR, within an FCC-compliant mask.

MTFComm has hardware-validated its MTF modulation and coding architecture under controlled laboratory conditions, demonstrating performance beyond conventional wireless capacity limits.

Using two AMD RFSoC platforms, the system achieved 1.9 Gbps throughput in 8.2 MHz of occupied bandwidth, a bandwidth efficiency of 233 bits/s/Hz at a verified 12 dB SNR. Shannon's theorem predicts a maximum of 4.07 bits/s/Hz under identical conditions, confirming a 57x improvement.

All measurements used FCC-compliant spectral masks, based on the signal's certified 20 dB bandwidth at 100 kHz resolution bandwidth.

Key Hardware-Validated Results

• 57x improvement in bandwidth efficiency over conventional wireless capacity limits
• 233 bits/s/Hz achieved vs. 4.07 bits/s/Hz theoretical maximum
• 1.9 Gbps throughput in 8.2 MHz of occupied bandwidth
• Operation verified at 12 dB SNR via Bit Error Rate testing
• FCC-compliant spectral mask, certified 20 dB bandwidth (100 kHz RBW)
• Constant-envelope waveform, suitable for satellite and battery-constrained devices

How This Is Possible

Shannon's capacity theorem relies on four simplifying assumptions: that the channel is linear, memoryless, affected only by Gaussian noise, and strictly band-limited. These assumptions enable an elegant closed-form solution, but they describe an idealized mathematical model rather than a fully physical communication system.

MTF technology replaces all four of these assumptions by using nonlinear operation, time-domain memory, signal-dependent noise behavior, and time-limited signaling rather than strictly band-limited channels. By operating in this real-world physical regime, the MTF system unlocks spectral efficiency far beyond what is predicted by the classical Shannon framework.

What This Unlocks

• Massive increases in network capacity without acquiring new spectrum
• Fibre-class wireless performance where fibre is impractical or impossible
• Dramatically higher user density within existing licensed bands
• Significant reductions in power consumption and infrastructure cost
• Direct applicability to cellular, private wireless, Wi-Fi, and satellite links

In practical terms, this is equivalent to transforming a one-lane spectrum band into a 57 multi-lane digital highway without adding any new spectrum.
