Real-World Hardware Demonstration Validates 57× Gain Over Shannon Capacity

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

MTFComm has completed a real-world hardware demonstration of its proprietary MTF modulation and coding architecture, validating operation beyond the classical Shannon capacity model under controlled laboratory conditions.

Using two identical AMD RFSoC platforms, the system achieved a measured throughput of 1.9 Gbps while occupying only 8.2 MHz of bandwidth, resulting in a bandwidth efficiency of 233 bits/s/Hz at a verified 12 dB signal-to-noise ratio. Under these exact same conditions, Shannon’s theoretical limit predicts a maximum of 4.07 bits/s/Hz, confirming a 57× improvement in spectral efficiency.

All measurements were performed using FCC-compliant spectral masks, based on the signal’s certified 20 dB bandwidth with a 100 kHz resolution bandwidth, confirming that these results reflect a standards-compliant, real-world system rather than a simulation artifact.

Key Hardware-Validated Results

  • 57× improvement in bandwidth efficiency over Shannon capacity
  • 233 bits/s/Hz achieved vs. 4.07 bits/s/Hz theoretical limit
  • 1.9 Gbps throughput in 8.2 MHz of occupied bandwidth
  • Verified operation at 12 dB SNR via Bit Error Rate testing
  • FCC-compliant spectral mask using certified 20 dB bandwidth (100 kHz RBW)
  • Constant-envelope waveform suitable for satellite and battery-powered devices
  • Compatible with existing cellular, Wi-Fi, Bluetooth, and satellite systems

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.
