External RF Interference Hunting
Elevated RTWP, degraded uplink, dropped calls with no fault found on the site. We sweep the band, correlate across affected sectors, take bearings in the field and locate the emitter — then prove the fix with post-mitigation measurements.
External interference is the problem that stays open. The site sweeps clean, the antenna line passes, the alarms clear — and the uplink is still degraded. It stays open because finding the source means leaving the site and working the RF environment around it, which is a different discipline from site maintenance.

Data Correlation
Correlate PRB/RTWP/RSSI/noise-floor across sites and analyze time-based patterns to narrow the area.
Field Hunt
Mobile/portable spectrum sweeps with directional/DF antennas, triangulation and localization.
Mapping & Verification
KML mapping and customer-coordinated ON/OFF verification of the suspected source.
Mitigate & Validate
Coordinate mitigation, re-scan, confirm noise-floor recovery, deliver closeout package.
What sets this apart
What clients rely on for external interference hunting & spectrum analysis.
A signature specialty
This is a core GCorp field service — not an occasional add-on.
Data + field + mapping
We combine OSS-data correlation, in-field DF and geospatial mapping in one workflow.
Proof of resolution
Every engagement ends with pre/post spectrum validation and documentation.
