Why did MWC 2025 mark a turning point for NTN connectivity?

Mobile World Congress 2025 confirmed what we suspected: satellite connectivity (NTN) is no longer a topic for the future, but rather for today. Present with our partner Anritsu, we demonstrated how our OTRAC beacon automatically switches to satellite if the 4G network is lost. A look back at a week rich in meetings and strong signals for the market.

NTN at the heart of discussions

For NEYOS, this was our second appearance at MWC. This show brings together all the latest trends.

Every year, the MWC is an international trade show where mobile tech players gather to present their latest products and discuss major developments in the sector.

And this year, the change was clear: NTN (Non-Terrestrial Network) was a central theme of discussions and demonstrations.

A concrete demonstration with Anritsu

NEYOS side

The demonstration consisted of placing an OTRAC beacon in a situation of progressive loss of cellular signal. When the level becomes insufficient, the beacon automatically triggers a switchover to the NTN satellite, with no loss of session.

To make this process easy to understand, we have developed a simulation interface enabling you to :

• Control the connection mode (cellular, satellite or mixed),
• Visualize in real time the network indicators measured by the beacon (RSRP - measurement of the strength of the signal received by the beacon, BER - data transmission error rate, RSRQ - measurement of the quality of the signal received by the beacon),
• Adjust thresholds to test different terrain scenarios (dense forest, deep valley, isolated area).

In this way, the demonstration doesn't just show that the beacon "stays connected": it also shows what radio data triggers the switchover, and how this data is used to guarantee continuity of service.

On the Anritsu side

This experiment was made possible by Anritsu's MT8821C NTN NB-IoT network simulator. This equipment enables controlled reproduction of field conditions, including :

• progressive attenuation of the cellular signal
• simulation of satellite propagation delays,
• evaluation of RF sensitivity in degraded environments,
• validation of the TN/NTN reselection process, while maintaining an active session.

By combining the NEYOS interface and the Anritsu simulator, we were able to clearly and measurably demonstrate the beacon's robustness in contexts where land coverage disappears completely: forest, mountain, maritime or desert areas.

NTN: a subject on the rise

The contrast with the previous edition is striking:

• In 2024, NTN was still vague and exploratory.
• In 2025, it is becoming a strategic focus for manufacturers, operators and IoT players.

Today, GEO solutions (geostationary satellites) are the ones that enable the deployment of reliable, tangible services. This is the basis on which we are already operating.

But LEO (low earth orbit) is gradually coming on stream, supported by new constellations. The complementary nature of the two orbits promises exciting developments for NTN in the years ahead.

Key points for the future

This show confirms the obvious: things are speeding up.

Discussions with industry players show that the ecosystem is now ready to adopt NTN on a massive scale.

For NEYOS, this is already opening up new, very concrete prospects: broader use cases, technological collaborations and strategic partnerships.

Many thanks to Anritsu for this collaboration, and to all those who came to share their visions and needs with us.

MWC 2025 is an important milestone and opens up great prospects for the future.
