Key Features
Cellular Network Monitoring
- Network Support: Near real-time monitoring for CDMA, GSM, WCDMA, UMTS, LTE, TD-SCDMA, and 5G NR (NSA and SA). Detects carrier aggregation (LTE-Advanced).
- Data Metrics: Captures current and neighboring cell information including MCC, MNC, LAC/TAC, CID/CI, RNC, PSC/PCI, channels, bandwidths, frequencies, and bands.
- Mapping & Geolocation: * Approximates cell tower locations and addresses via geolocation services.
- Groups cell tower sectors on Google Maps / OSM.
- Note: Precision relies on multi-sector detection (3 cells); single cell readings indicate the center of the serving area.
- Data Export: Supports background data collection and session exporting to CSV and KML (compatible with Google Earth).
- Hardware Controls: Dual SIM support and access to hidden firmware service menus for forcing LTE-only modes or locking specific LTE bands (on supported Samsung and MIUI devices).
Wi-Fi Network Analysis
- Network Metrics: Identifies SSID, BSSID, router manufacturer, connection speed, estimated distance to the access point, and signal strength graphing over time.
- Network Configuration: Displays local IP address, subnet mask, gateway IP, DHCP server address, and DNS addresses.
- Frequency & Channel Analysis: Supports 2.4GHz, 5GHz, and 6GHz spectrum bands with channel widths of 20MHz, 40MHz, 80MHz, 160MHz, and 80+80MHz.
- Standards & Security:
- Technologies: Wi-Fi 1 (802.11a) through Wi-Fi 6E (802.11ax in 6GHz).
- Security/Encryption: WPA3, OWE, WPA2, WPA, WEP, 802.1x/EAP protocols; AES and TKIP encryption.
- Network Security: Identifies active devices connected to the wireless network.
Required Permissions
- PHONE: Required for multi-SIM support and retrieving network type/service states. (No call functionality utilized).
- LOCATION: Required for scanning Wi-Fi access points, fetching current/neighboring cell data, identifying carrier names, and accessing GPS location.
Changelog & Known Issues
- Fixed: Resolved bugs regarding loading cell databases via BTSearch.
- Improved: Minor user interface updates and stability enhancements.
- Known Issue: Cell towers search functionality is currently broken.
