Link Planner
Point-to-point microwave links on terrain-accurate path profiles, ITU-R throughout, with ACMA coordination.
The radio engineering platform
No IM₃ by name.
No interference by design.
Every Pro tool, free for 14 days No card needed Link Planner, Coverage Predictor, ACMA Database Map and 21 more.● 105 tools live 55,000+ real parts Built to published standards
Where to start
Design it, license it, or have it built
One team designs the system, assigns the frequency and builds the software, so the work carries straight through from the first calculation to the finished product.
Live Tools
The tools we use, open to you
These are not calculators built to fill a page. They are the tools we reach for on real jobs, which is why they show their working, cite the standard behind each number and run on actual vendor hardware rather than typical values.
Sample result
Loading the sample result This sample did not load. The tool is one click away.
Built to the published standards
Trusted where it matters
Accredited, checked and in use
Refreshed every day
The national licence register is pulled fresh every day, so site, licence and interference checks start from what is actually on air.
Built on published standards
Calculations implement the published methods of ITU-R, ETSI, 3GPP, ARPANSA and Standards Australia. Propagation and link modules are verified against independent reference implementations of the ITU-R Recommendations they apply, and cite the edition used.

55,000+ real parts, not placeholders
35 equipment categories of actual vendor hardware, with measured antenna patterns and manufacturer datasheet figures behind the numbers.
Used on operational mine sitesMC² 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 clientProSEA
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 membershipARCIA
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.
Reimagining the Australian Spectrum
The ACMA register, the way it should have always worked
Spending hours digging through the ACMA portal, rebuilding spreadsheets for every project, or waiting on answers about available spectrum is still the norm. That is exactly why the ACMA Spectrum Tool exists. It gives you a live, searchable view of every apparatus licence in Australia, so you can run coordination checks, build frequency plans, and understand your spectrum environment in one place.

And when the plan is right, we lodge it
Anyone can publish a calculator. Far fewer can complete the frequency assignment and lodge the apparatus licence application that follows. Our accreditation is general, so it is not limited to a particular service, band or licence type.

Telecommunications NewWhat Is a Good RSRP, RSRQ and SINR? 4G and 5G Signal Strength Explained
By the most widely published thresholds, a good 4G signal is an RSRP of -90 dBm or better, an RSRQ of -15 dB or better and a SINR of 13 dB or better.

NewFDMA vs TDMA Underground: Why Amplifier Group Delay Favours FDMA on Leaky Feeder and DAS Cascades
On the surface, TDMA wins the spectrum argument: two calls on one 12.5 kHz carrier for DMR and P25 Phase 2, four on 25 kHz for TETRA.

NewDAMM BS422 Review: Mast Top Base Station Design for Australian Mines
The DAMM BS422 is a software defined outdoor base station that runs up to four carriers of TETRA, DMR Tier III, TEDS or analogue from one 12 kg IP65 box, and it is built to sit at the top of the mast beside the antennas instead of in a shelter at the bottom.
