Cellular Network Analyzer

CNA (Cellular Network Analyser) turns your Android phone into a field-test tool for 2G, 3G, 4G LTE and 5G NR. Whether you are simply curious or a network professional, CNA lets you see your live connection in detail, map signal coverage as you move, log a full drive test, and even hunt down the true location of the cell tower you are connected to. Then export it all to Google Earth or CSV. See https://gjsoft.info/cna for full description FREE, ALWAYS: - Current Connection, Geographical: your position and the connected tower on a live map, with the distance, the link quality and the bands in use. - Current Connection, Spectrum: every band and carrier your phone is using, placed on the real downlink and uplink spectrum, with (E)ARFCN, frequency, bandwidth, PCI, RSRP and RSRQ. - Sign in with your Google account for 10 free cell-tower location lookups every month. CNA PRO: - Build Coverage Map: paint a colour-coded signal-strength map as you walk or drive, and export it to Google Earth in RSRP or RSRQ. - Route Logging: record your connection and position along a route, then replay every position and tower on an interactive map. - Tower Hunt: pin down a cell tower's true location to within tens of metres, using the timing advance your phone already exchanges with the network. Public tower locations are often hundreds of metres off; a hunt measures the real position, and shared hunts make everyone's lookups better. - Unlimited cell-tower location lookups under a fair-use policy. - Logging and hunting tools run in the background, and can even run in parallel. BEAUTIFUL EXPORTS: Export any coverage map, route log or hunt as a KMZ file for Google Earth, or as CSV for a spreadsheet. SUPPORTS: GSM, UMTS, LTE and 5G NR. What you see depends on how much your phone's modem exposes to Android, so some fields may read N/A on certain devices. CNA PRO SUBSCRIPTION: CNA Pro is an optional subscription that unlocks the coverage, route-logging and hunting tools plus unlimited lookups. It starts with a one-month free trial; if you cancel during the trial you are charged nothing. After the trial you can choose for a monthly or annual subscription. Payment is charged to your Google Play account, the subscription renews automatically until cancelled, and you can cancel any time in Google Play. Prices may vary by region and tax. PRIVACY: Tower hunts you choose to share include only the estimated tower position and a short quality summary, never your GPS track. Sharing is optional and can be turned off in Preferences. Note: CNA is a spare-time project. Tower-location estimates are best-effort and not guaranteed exact. CNA is not a substitute for emergency or professional survey equipment. Questions or suggestions?
