The register never stands still
Licences are issued, varied and cancelled every day. A check run on last month's export can already be wrong about what is on air.
About us
Spectrum is finite.
We engineer like it.
noIM₃ is a radio engineering business from Adelaide, South Australia. We build engineering tools for engineers anywhere, design communications systems, and assign frequencies in Australia as an ACMA accredited person, with an engine that weighs every assignment against nearby sites.

Why we exist
Most spectrum is assigned one request at a time
A channel is chosen because it passes today. What it takes from the sites around it, and from the next request, rarely makes it onto the paperwork, so the problems surface years later at someone else's site.
02
Every assignment has a cost
A channel given to one site can take options away from every site within reach of it. That cost is real, but it is rarely counted.
03
The picture is rebuilt every time
Coordination is still pieced together from exports and spreadsheets, so each engineer rebuilds the same picture from scratch, one version at a time.
The engine
Ahead of the spectrum, not behind it
The engine reads Australia's national licence register every day and keeps an answer ready for every channel at every site. Every spectrum decision made on the platform feeds back into it, so each new assignment is chosen with the whole picture in view.
- 01
The register, every morning
The full national licence register is pulled fresh every day. Every new licence, variation and cancellation is compared against the day before.
- 02
Every channel, at every site
The engine works out which channels can still be assigned at every site, and records the rule that decides each one, so the answer is ready before anyone asks.
- 03
The cascade
For every option it counts what an assignment would take from the sites around it: the channels they would lose, and the room they would have to grow.
- 04
The choice that leaves room
Where the rules leave a choice, it takes the channel that leaves the most room for the next site. Each decision feeds back in, so the picture sharpens with use.
The engine keeps only the frequency, bandwidth and location of each assignment, anonymously. Other customers never see it, and it is used only to keep nearby assignments clear of interference. How we handle spectrum records
What we do
One team, from the first calculation to the licence
Design it, license it, or have it built. The same team does all three, so nothing is lost between them.
Engineering
Tools built to published standards
105 live tools for radio, electrical and network design, for engineers anywhere. They show their working and cite the standard behind each number.
Browse the tools → LicensingFrequency assignment, lodged
In Australia, we coordinate against the live register and lodge the application under our own ACMA accreditation, which is general, so it is not limited to a particular service, band or licence type.
Request an assignment → Custom toolsSoftware built to order
Every tool on this site was built here. Describe what you need, from a calculator to a full application, and we build it, host it and maintain it.

Used on operational mine sites MC² Engineered
Underground radio and frequency planning
MC² Engineered built the frequency plan for an underground radio network in the Frequency Coordination Tool, taking most of the manual spreadsheet work out of it. On operational mine sites they also use noIM₃ to check underground frequency plans for intermodulation interference.

Licensing client ProSEA
Non-assigned marine ship station licence
noIM₃ handled our non-assigned marine ship station licence from start to finish and made the whole thing seamless and easy.

Industry membership ARCIA
Member of the Australian Radio Communications Industry Association since July 2026
ARCIA is the peak body for Australia's radio and critical communications industry. Membership keeps our engineering close to the standards, training and regulatory work that shape the sector.

Accredited person ACMA
Accredited to assign
Our ACMA accreditation is general, so it is not limited to a particular service, band or licence type. Every assignment is coordinated and lodged by an accredited person.
What we stand for
The principles that shape how we build
Engineering rigour over convenience
Every tool is built to produce results you can stand behind in the field, in a compliance submission or in front of a client. We don't round numbers to make an output look cleaner, and we don't simplify a model to make it faster.
No black boxes
Results show their working and cite the standard behind each number, and every engine verdict names the rule that decided it. When the system is critical, the reasoning has to be visible.
Built for the engineer, not just the enterprise
Critical communications are delivered on projects of every size. A sole operator on a remote site gets the same quality of tooling as a large infrastructure firm.
Australian made, open to anyone
We are based in Adelaide and know the Australian spectrum and licensing framework closely. The tools are built to published international standards, such as ITU-R, IEC and IEEE, so engineers anywhere can use them.
Never finished
New tools, refined models and a register that is read again every morning. What you use today will be better tomorrow.
Where we're headed
A discipline that keeps getting sharper
The aim is to raise the quality and consistency of communications engineering, with better data, better models and better decisions available to every engineer.
Every channel, every site, every day
The tools, frequency assignment and the engine, all working from the same register.
Seeing congestion coming
Reading the register's history, the channel plans and where each band is heading, to show which bands are filling up and advise what spectrum to license before it runs short.
A digital twin that proves a design
Stand up a design, run real traffic across it and stress it against weather, fading and interference, so it is proven to meet its requirements before anyone mobilises to site.

noIM₃ was built to help make that happen. Start with the tools, or bring us the job and we will design it, license it or build it.
