Mountain valley site

A private 5G tower, an automatic weather station, a compact radar and a seismic vault on real alpine terrain, joined to an edge data centre that admits, times and publishes every observation.

Network scenes here: Satellite direct to device in a mountain valley

Tour transcript

1. A valley floor on real terrain: one tower, one edge module and three instrument classes form an observing site.
2. The tower carries the private 5G cell and the site’s time reference.
3. The edge module admits each station, checks what it is and keeps its data through outages.
4. The weather station measures to its WMO siting class; its metadata travels with every value.
5. A compact radar sees the valley floor that a distant national radar overshoots.
6. Red cells are the ground in sight of the tower top, computed on the terrain with refraction.

In this scene

Massive-MIMO AAU ×3

Three sectors of active antennas carry the private 5G cell that every station on the site joins. (3GPP TS 38.104, O-RAN WG4)

GNSS timing antenna

Disciplines the site clock so every observation carries a traceable time and its uncertainty. (IEEE 1588-2019, ITU-T G.8272)

Compute racks

The site authority: admits each instrument, checks its attestation, buffers through outages and publishes. (IETF RATS (RFC 9334), OGC SensorThings API)

aws-mast

Wind at 10 m, temperature and humidity in a shield at 1.5–2 m, sited to its WMO class. (WMO-No. 8, WIGOS metadata (WMO-No. 1192))

xradar

A compact X-band radar fills the gaps national S-band radars leave under the beam in mountain valleys. (ODIM HDF5, WMO radar data exchange)

vault

A broadband seismometer on a pier cast to bedrock, timed by GNSS and streaming in miniSEED. (FDSN StationXML, SEED / miniSEED)
