NetMonster monitors displays and logs cellular network data in real time providing precise cell tower identifiers signal metrics and coverage insights.

Key Features:
• Real-Time Monitoring: View serving and neighbor cell data including CID LAC/TAC eNB/gNB IDs PCI/PSC ARFCN and frequency bands.
• Signal Quality Analysis: Track RF metrics (RSSI RSRP RSRQ SINR CQI) with live visual indicators and explanations of how measurements impact coverage and theoretical maximum speeds.
• Cell Tower Mapping & Logs: Keep continuous logs of connected cells during your session. Browse mapped locations filter cells manually correct tower positions and export data.
• Carrier Aggregation & 5G: Detect LTE-Advanced Carrier Aggregation (CA) and inspect 5G NSA vs. 5G SA status-including active transmission vs. deployment signaling and 4G+5G NSA aggregation.

Supported Technologies:
• 2G: GSM CDMA
• 3G: WCDMA TD-SCDMA
• 4G: LTE LTE-A (Carrier Aggregation)
• 5G: NSA (Non-Standalone) SA (Standalone)
