EU/ETSI real‑world throughput vs distance — park test (Wi-Fi HaLow MM8108 EKH‑01/EKH‑19)

General

Hi everyone,

we got a chance to take the Wi‑Fi HaLow eval kits outside and do a quick real-world test. Since we’re based in Europe, the radio was explicitly set to ETSI (EU compliance) — so these numbers are meant to reflect what you can realistically expect under EU limits - in contrast to the typically promoted FCC/US conditions.

The test setup was kept simple: one unit stayed put on a wooden structure, and the other one was carried away along a path in a local park. There were some trees and partial obstruction most of the time, so no perfect line of sight.

Setup (Morse Micro OpenWrt integrated rangetest)

  • Regulatory setting: ETSI (EU)

  • Stationary unit: MM8108‑EKH‑01, ~2 m above ground

  • Mobile/handheld unit: MM8108‑EKH‑19, ~1 m above ground

  • Location: local park, trees/partial obstruction (no clear LOS)

  • Date: 2025‑11‑10

The plot includes UDP and TCP throughput in both directions.

Conclusion (ETSI / real‑world park)

  • Up to ~100 m: mostly 4–6 Mbit/s, very stable

  • Around ~200 m: throughput drops to about 2–4 Mbit/s, still very reliable

  • Around ~300 m: we hit the limit — some transfers still worked at roughly ~1 Mbit/s, while others failed

Feedback and comparisons from others are very welcome—especially if you’ve run similar outdoor tests under ETSI conditions.

Cheers,
Simon

Thank you for sharing your results! I have been looking for test results since I haven’t been able to really understand what speeds are possible in Europe given the restrictions. So I am surprised about the speed you get. :slight_smile:

The range is a bit disappointing though, I thought it would go down to a much slower rate but still keep the connection working. From what you describe it seemed to be more of a cliff once it got down to 1Mbit?

Cheers,

Henrik

Good point @lase, and thank you for the remarks.

From the measurements, the throughput decreases fairly gradually from around 6 Mbit/s down to roughly 1–2 Mbit/s as distance increases. Below that, I didn’t really observe a stable kbit/s‑level regime — instead, once conditions worsened further, the link tended to become unstable and eventually stop working. The behavior near ~1 Mbit/s can indeed feel a bit like a “cliff.”

One additional detail that may help interpret the plot: for 100 m, 200 m, and 300 m I took two measurements each (this isn’t clearly indicated in the figure). One was recorded while moving away from the stationary unit, and another while returning along a different walking path. That’s why, for example at 200 m, you see one set of points around 3–5 Mbit/s and another around 1–2 Mbit/s. The difference is most likely caused by varying levels of obstruction, as the path was only partially line‑of‑sight with trees in between.

Cheers
