SignalVerify

SignalVerify — Field-measured direct-to-device / non-terrestrial network (NTN) validation records: per-test rows carrying an explicit device-captured NTN indicator (satellite vs terrestrial path), RSRP and RSRQ, a 0-4 signal-level grade, timing advance and a path distance derived from it, joined to voice-call-completion and SMS-delivery outcomes — i.e. ground-truth evidence of which physical path carried each real service event.. Micro-specialist: ~3 employees, Paris-area (Croissy-sur-Seine) France, no funding history. Volume is negligible in absolute terms, but the dataset is arguably the sc…

SignalVerify offers (Alternative, Geospatial, Reference) — Small but exceptionally high-value: thousands to low hundreds of thousands of individually evidenced test events per campaign (call + SMS attempts across market/geo grids), not a big-data stream — the asset is the labelled path-type ground truth, not record count.

Verifying direct-to-device / satellite-to-cell coverage claims made to regulators and subscribers; pre-launch baseline and post-launch degradation tracking for D2D services; constellation-performance benchmarking (does the link behave as the geometry predicts); emergency-services reachability evidence in dead zones; due diligence and audit evidence for satellite-D2D commercial deals; rare labelled training data for NTN link-budget, handover and fallback models — an area with essentially no public ground-truth datasets.

The data is with 2 years of history.

Coverage spans Europe, US; Wireless Telecommunication Services, Aerospace & Defense; alternative, geospatial, reference; equities.
