Holds the link in motion
Acquires and keeps the link through high Doppler, multipath fading, and deep fades. Proven end to end at low signal-to-noise with the full Doppler envelope, not just on paper.
Three products for one radio chain: a mesh waveform that closes the link, a planning tool that predicts it, and a front end that carries it. Built for the air, for the field, and for the people who have to make radios work.
Every radio link is three problems in one. The waveform decides what you send. The channel decides what survives the trip. The front end decides what you can actually hear at the other end. Get any one wrong and the other two cannot save you.
Most teams buy each piece from a different vendor and find out at integration that none of them were designed with the others in mind.
We build all three — the SDR Waveform, SigB Spectra, and the RF Front End — as one family. Each stands on its own. Together they are a radio you can plan, fly, and trust.
Our own airborne mesh radio waveform — baseband and networking, secure, adaptive, and portable to any SCA-compliant software-defined radio.

Read more ↓A wideband, high-power, direct-sampling SDR front end on a single PC card — and the road to our own silicon.
Read more ↓SigB's own software-defined radio waveform: a complete baseband physical layer and mesh networking stack for airborne and mobile platforms, where nodes move fast, links fade, and there is no infrastructure to lean on. Written to run on general-purpose-processor radios and compliant with the SCA 2.2.2 standard by design.
Acquires and keeps the link through high Doppler, multipath fading, and deep fades. Proven end to end at low signal-to-noise with the full Doppler envelope, not just on paper.
Frequency hopping with AES-256 transmission security and AES-256 payload encryption. Standard, published algorithms, verified against published test vectors.
Multiple service modes from robust long-range voice and data to megabit-class throughput. The receiver adopts modulation and code rate from every burst on its own. Mesh networking with relay and multi-hop range extension.
A full document set — requirement, system, interface, functional, detailed design, and test specifications — with every requirement traced to a test scenario. Ready to port to your radio.
SigB Spectra is our RF planning and modelling desktop application. Drop a transmitter on a real map, with real terrain and land cover, and see coverage, interference, capacity, and link performance in seconds. One tool spanning telecom, broadcast, defence, and point-to-point links.
Global terrain and land-cover data downloaded straight from the app. A library of industry-standard propagation models, from free-space and Longley-Rice to 3GPP 5G NR and ray tracing.
Multi-site best-server, interference, and quality maps for GSM, UMTS, LTE, and 5G NR. Neighbour and PCI planning, capacity and throughput, automatic cell planning, and single-frequency-network coverage.
Radar detection coverage, jamming and electronic-warfare analysis, emitter geolocation, and a full spectrum-management suite: interference matrices, automatic frequency assignment, and Monte Carlo interference studies.
Microwave link budgets with rain, gas, and multipath availability. Export to GeoTIFF, KML, GeoJSON, and Shapefile for QGIS and Google Earth. Ships as a self-contained Windows installer and runs fully offline.
A software-defined radio front end on a single add-in card for a standard PC: 30 to 406 MHz across six bands, high transmit power, and direct RF sampling with no analog mixing stage, so retuning is a digital step. Revision A runs on proven off-the-shelf silicon. Revision B replaces it with SigB's own RF front-end chipset.
Six switched sub-bands from 30 to 406 MHz with clean, mask-compliant emissions on every path, and a power amplifier chain rated around 56 W average and 90 W peak.
Conversion between analog and digital happens at RF on a single RF-sampling system-on-chip. No local oscillator, no mixer, no image filtering. Retune in microseconds.
A GPS-disciplined, oven-controlled reference keeps every node on one clock, so frequency hopping and mesh timing stay aligned across the whole network.
A reproducible, script-generated schematic and board with every design decision on record. Revision A ships on off-the-shelf parts. Revision B swaps in SigB's custom digital front-end SoC and front-end module.

We work with a small number of partners each year. The right first step is usually a conversation. Or look at how we validate.
