The waveform
after OFDM.
MTF is a patented physical layer from the co-inventor of wideband OFDM. It drops into the radio you already build: your coding, framing and MAC stay, and only the physical layer changes. Then you choose what to win: range on less power, more bits per hertz, or raw throughput.

Every radio is a compromise between power, spectrum and speed.
OFDM, the waveform under Wi-Fi, 4G and 5G, peaks far above its average power, so amplifiers are backed off to a fraction of their rating. Spectrum is licensed by the megahertz. Every extra bit per second costs signal-to-noise. MTF moves that frontier and lets you choose the corner you need to win.
Power. Constant-envelope configurations run the amplifier fully saturated, with no back-off.
Spectrum. Mask-matched spreading fits the regulator's mask, validated to −70 dBr out of band.
Throughput. The same core, run linear, carries higher-order modulation for the most bits per channel.
One core. Three configurations.
Each configuration is the same patented core, tuned to win a different axis of the link. Pick one per application.
MTF Reach
A constant envelope and a large SNR gain let the amplifier run flat out, for links that must go far, run for years on a battery, or keep working under jamming.
MTF Spectra
A narrowband, constant-envelope waveform that carries far more throughput per allocated hertz, with the amplifier still running saturated.
MTF Velocity
MTF Core on its own, with higher-order modulation: the highest bit rate per channel, where signal is plentiful and spectrum is the constraint.
Only the physical layer changes.
MTF keeps a conventional signal at its core and inserts its processing between your channel coding and your power amplifier. On receive, an iterative interference-cancelling detector reverses it.
*Reach and Spectra are constant-envelope (0 dB PAPR). Velocity is linear and uses conventional back-off, as OFDM does.
How MTF worksPatented. Published. Running in silicon.
From the co-inventor of W-OFDM.
Dr. Michel Fattouche co-founded Wi-LAN around wideband OFDM, which was adopted in IEEE 802.16a and licensed by more than 200 companies. MTF is his next waveform.

We license. You build. We never compete.
MTFComm licenses its physical layer to the companies that build radios, chips, satellites and networks. FPGA images for Reach and Velocity are available to qualified partners for evaluation.
