NetMonster

What Does Your Mobile Network Really Reveal?

Have you ever wondered what lies beneath the surface of your mobile connection? NetMonster, developed by Michal Mroček, is a specialized diagnostic tool that grants you direct access to a wealth of technical data about surrounding cellular networks. Unlike typical network utility apps that merely display signal strength, this application digs into the raw infrastructure details—revealing everything from neighboring towers to precise frequency bands. With a single tap, NetMonster scans and lists nearby devices, presenting critical information such as connection type, operator identity, operating frequency, and even real-time link speed. It transforms your smartphone into a portable network analyzer, ideal for engineers, field technicians, or anyone curious about the invisible architecture of mobile communications.

Core Features and Data Capabilities

Once activated, NetMonster adapts its output based on the specific generation of cellular technology in use. For 2G connections, it exposes parameters like Cell ID (CID), Location Area Code (LAC), Receive Level (RXL), Timing Advance (TA), Base Station Identity Code (BSIC), Absolute Radio Frequency Channel Number (ARFCN), and the associated band—alongside neighbor cell data such as CID, LAC, BSIC, RXL, and ARFCN. For 3G, the app reports Cell Identity (CI), Radio Network Controller (RNC), CID, LAC, Primary Scrambling Code (PSC), Received Signal Code Power (RSCP), UARFCN, band, and neighboring cells with PSC, RSCP, and UARFCN. On 4G LTE networks, you get CI, eNB ID, CID, Tracking Area Code (TAC), Physical Cell ID (PCI), RSSI, RSRP, RSRQ, Signal-to-Noise Ratio (SNR), Channel Quality Indicator (CQI), TA, EARFCN, band, and neighbor cells with PCI, RSRP, RSRQ, and SNR. For the latest 5G NR, NetMonster displays NCI, TAC, PCI, RSRP, RSRQ, SNR, ARFCN, and band. Additionally, CDMA networks yield IDB, SID, NID, latitude/longitude, RSSI, EC/IO, and SNR. The app requires only two permissions to function correctly: location access and mobile data usage. No complex calibration or root access is needed—just enable these settings, and the tool begins populating with real-time network intelligence.

Technical Disclaimer

This application requires an active internet connection for data retrieval and may consume mobile data. It contains no in-app purchases, but certain features depend on device hardware and carrier support. Location services must be enabled for accurate tower identification. Not all parameters may be available on every network or device. No age restrictions apply, but users should be aware that continuous network scanning can increase battery consumption.
