Feels like AI is slowly getting integrated into telecom without people really noticing.

Not talking about ChatGPT-style stuff, but more what operators and devices are starting to do in the background.

For example:

• Real-time audio translation during calls (different languages, live)
• Network optimization (AI predicting congestion before it happens)
• Call quality enhancement (noise removal, voice isolation, etc.)
• Spam detection (blocking robocalls more intelligently)
• Customer support automation (chatbots, but getting less terrible)

What’s interesting is that a lot of this is already happening quietly.

You don’t really “see” AI, but it’s shaping how the network behaves.

At the same time, it raises a few questions, how much data is being analyzed behind the scenes? Are we trading privacy for better performance? Do people actually notice the improvements?

Personally I feel like some use cases (like noise reduction or spam detection) are clearly useful, but others feel a bit invisible or overhyped.

What are your thoughts on this ?

Kazakhstan: 5G rollout already impacting real-world mobile performance (nPerf data)

Body:
Since 5G launch in 2022, Kazakhstan shows clear performance gains:

• Download speeds ×1.6
• Latency ↓ 36.5%

By 2025:

• ~40.5 Mbps down / 13.5 Mbps up

5G usage is still limited (~6.75% of tests), but improvements are already visible, driven by both 5G rollout and continued 4G investment.

Even with low 5G share, network modernization (4G + 5G) can significantly improve real-world performance.

Using nPerf test data (2021 → Q1 2026), 5G share of mobile usage went from ~6% to ~28.5% globally, with a clear recent acceleration.

In Europe, some countries are already near parity:

• Germany → 49.2%
• Portugal → 48.3%
• France → 43.6%
• UK → 42.4%
• Italy → 40.3%

So in these markets, 5G is no longer marginal, it’s becoming the default access layer.

At the same time, adoption remains very uneven (e.g. ~6% in Nigeria, ~0% observed in Cameroon).

We’re not in a “deployment phase” anymore in some regions, but in a usage transition phase, which likely has implications for traffic patterns, congestion, and interconnection.

Some interesting data from Northern Europe this year.

Sweden comes out on top overall (~123k), just ahead of Norway (~119k) and Denmark (~118k). Finland trails a bit (~101k), but the whole region is performing at a high level.

What stands out with Sweden is balance:

• ~201 Mbps download
• ~158 Mbps upload
• ~26 ms latency

Strong across the board, likely helped by growing fiber adoption.

Other countries shine in specific areas.

Denmark leads in browsing (~80.6%), so websites load very fast.
Norway leads in streaming (~83.5%) with similarly low latency (~26 ms).
Finland is a bit behind mainly due to higher latency (~40 ms), but still solid overall.

Across the region, speeds above 100 Mbps are basically standard.

It’s a good reminder that performance isn’t just one number — speed, latency, browsing, streaming all matter.

TL;DR

Sweden leads overall.
Denmark = best browsing.
Norway = best streaming.
Northern Europe = very strong networks.

Some interesting numbers from 2025 mobile network tests.

In La Réunion and Guadeloupe, average mobile speeds are roughly twice as high as in mainland France.

Download speeds:

• Guadeloupe → ~236 Mbps
• La Réunion → ~227 Mbps
• Mainland France → ~118 Mbps

Upload speeds:

• Guadeloupe → ~31.4 Mbps
• La Réunion → ~28 Mbps
• Mainland France → ~15.7 Mbps

So yeah, on average, overseas users are getting about 2x the throughput.

But raw speed isn’t the whole story.

Latency and real usage differ depending on the territory.

• La Réunion → ~23 ms latency
• Guadeloupe → ~32 ms
• Mainland France → ~34 ms

La Réunion is noticeably more responsive, which matters for gaming, calls, etc.

Browsing performance is a bit different:

• Guadeloupe → ~73.4%
• Mainland → ~73.7%
• La Réunion → ~64.9%

So despite higher speeds, La Réunion shows weaker web browsing performance.

Streaming is pretty similar across the board, around ~80%, so HD video is generally fine.

5G is still not dominant, but growing fast.

Share of tests done on 5G:

• La Réunion → 9% → 33% (2023 → 2025)
• Guadeloupe → 0.16% → 20%

So adoption is clearly accelerating, especially in La Réunion.

One likely explanation for the higher speeds:

Smaller territories → more concentrated infrastructure → fewer rural coverage constraints compared to mainland France.

TL;DR

• Overseas France ≈ 2x faster mobile speeds than mainland France
• La Réunion = best latency
• Guadeloupe = better browsing
• 5G growing fast but still not dominant
• Smaller geography likely helps performance

Curious if people in other regions see similar patterns where smaller territories outperform larger countries.

This is completely normal. When you log out and uninstall the app, the next installation is recognized as a new device by our system. As a result, the local history on that device will appear empty.

However, your tests remain linked to your account (as long as they are synchronized). You can always find them in the History section on our website

Make sure your tests are properly synced to avoid losing access to them.

Wi-Fi behaves like radio waves.

That means obstacles matter a lot.

Walls, furniture, appliances, mirrors, and even water (including the human body) can absorb or reflect wireless signals.

If your router is hidden inside a cabinet or pushed into a corner of the house, a large portion of the signal may never reach your devices.

Simply placing the router:

• in a more central location
• slightly higher
• away from large obstacles

can dramatically improve signal quality and coverage.

Because wireless conditions change quickly over short distances, even moving the router a couple of meters can significantly improve performance.
