Free TOTAL RADIATED POWER (TRP) testing
Get a free Total Radiated Power measurement at The Things Conference 2026
Bring your IoT, wearable, or wireless device to the Radientum booth at The Things Conference 2026. In about 10 minutes, our RF engineers measure its Total Radiated Power (TRP) in a live anechoic chamber — a fast, honest reality check before certification or volume production.
A real test of your real device
Most teams don’t find out how their antenna actually performs until certification — or worse, until units are in the field underperforming on range and battery. At TTC 2026 you can find out on the spot if your device is about 15x15x15cm or smaller.
Bring your device to Booth S44. No appointment needed.
Walk up any time during show hours.
We measure its Total Radiated Power
With a CW-TRP measurement from 6 directions in a professional anechoic chamber
Our RF engineers read the result with you
Together we will analyse the result. What it means for range, battery life, and whether it’s likely to pass your expectations.
The whole thing takes about 10 minutes.
Unless we dive deeper into discussion.
One catch: we can only measure a device that’s ready to transmit
A TRP measurement needs your device configured for a non-signalling CW transmission. The measurement itself is quick but getting your device into that state takes a little planning. Show up unprepared and those 10 minutes turn into troubleshooting. Show up ready and you walk away with a number you can act on.
The checklist walks you through exactly what “ready” means, so your measurement counts.
What your device needs before it can be measured
- Device & modem maturity — the device boots successfully, runs without crashing or rebooting, and its modem software accepts direct test commands and responds reliably.
- Transmit configuration — the device can be commanded to emit a maximum-power CW signal at your target frequency, with a documented method to switch it into that transmit mode (e.g. a pre-programmed button mode or serial command).
- Battery endurance — the device can sustain at least 15 minutes of maximum-power CW transmission.
- Device size - The Things Conference 2026 measurement is limited to device about 15x15x15cm or below in size.
Built for teams shipping wireless products
If you’re developing a LoRaWAN or cellular IoT sensor, a wearable, an asset tracker, a medical device, or any battery-powered wireless product, radiated power is what decides your range and your battery life. If you’re bringing hardware to TTC 2026, bring it by — this is the fastest independent read you’ll get all show
Independent RF, antenna & EMI/EMC specialists
Radientum Oy is an independent antenna, RF and EMI/EMC design house that helps device makers get products to perform in the real world, speed up product development cycles by simulations and maximize chances of passing certification the first time. If your measurement raises questions, the same engineers can help you answer and debug them. From antenna design and simulations to EMI/EMC and pre-compliance to wireless / over-the-air testing. Radientum is has offices and laboratories at Tampere and Espoo in Finland.
Measurement at The Things Conference 2026 are done in collaboration with our partner waveLAB Ruhr GmbH - engineering office based in Essen, in the middle of the Ruhrgebiet. A niche provider of consulting and measurement services in the field of RF-technolgoy, which the larger accredited test houses cannot do according to independence from DIN EN 17025. They do pre-compliance EMC/EMF, Radio, SAR and Electrical Safety Testing in terms of regulatory aproval, as well as onsite EMC measurements for construction vehicles, trains and bigger machines. They are also a distributor for EMF products such as personal dosimeters (FieldSENSE) and EMF-RF safety sfotware (IXUS).
FAQ
Is the measurement really free?
Yes. Free, about 10 minutes, no strings attached but only at The Things Conference 2026.
Do I need to book a time?
No — walk up to Booth S44 any time during show hours. Prefer a guaranteed slot? Reserve one through our scheduler.
What does my device need to do?
Boot reliably, be able to transmit a maximum-power CW signal at your target frequency, and hold that for at least 15 minutes. The checklist covers all of it.
What is TRP, and what’s a “non-signalling CW” measurement?
Total Radiated Power is the total power your device’s antenna actually radiates — the real-world figure behind range and battery life. A non-signalling CW measurement uses a continuous test tone (no network connection), which is why your device needs to be put into a direct transmit mode.
What if my device isn’t fully ready?
Come by anyway. We’ll talk through your setup and what to change — you’ll leave knowing your next step.
Who runs the measurements?
Testing is carried out as a collaboration between Radientum and waveLAB Ruhr. In-venue anechoic chamber is provided by waveLAB Ruhr.
