584 Mbps upload — a lab breakthrough for the class
Bench testing pushed a single UE to 584 Mbps upload on 100 MHz of n77 — extraordinary headroom for a system this size, and the margin that keeps professional field links rock-solid.

1.1 km² covered from a single node at Anavysos
A standalone 5G SBBD on a 4.5 m light stand blanketed an entire salt flat with private 5G — streaming UHD at 80 Mbit/s to a Haivision StreamHub VM running on the node, with latency dropping to 13–16 ms.
We took a single 5G SBBD out to the ancient salt flat at Anavysos, south of Athens, to answer one question: how much ground can one node really cover in a deliberately hard setup?
The system ran fully standalone — one SBBD on a 4.5 m light stand, powered from an SBBP on camera batteries, with Starlink as the only backhaul. The flat sits about a metre below sea level, so the effective antenna height was just 2.5–3 m from the surrounding ground. That is a worst-case mounting for coverage, and exactly why we chose it.
Using only the integrated directional antenna (40° horizontal, 11 dBi) on n77 at 3 950 MHz with 100 MHz of bandwidth, the node blanketed the entire measured area — 1.1 km², a 1.3 km span — with only minimal glitches, even while we moved through the zone on a motorbike.
Throughout the trial a Haivision StreamHub ran as a VM directly on the SBBD edge server, ingesting a UHD feed at 80 Mbit/s with 100 ms encoder latency. For stretches of more than a minute and a half the system delivered 13–16 ms of network latency before settling back to the typical 20–30 ms — extraordinary for a system this size.
