Network Survey by Craxiom provides a focused toolkit for logging and analyzing Cellular, Wi-Fi, Bluetooth, and GNSS networks. It supports offline logging to GeoPackage or CSV and live streaming via MQTT or gRPC, with a background-location workflow and a privacy-conscious approach. Not ranked in any top list.
Pros & Cons
Logs cellular, Wi-Fi, Bluetooth and GNSS data in one app
Offline GeoPackage/CSV exports for analysis
Optional real-time streaming via MQTT or gRPC
Wi-Fi Watchlist with alerts and import capability
Streaming requires external MQTT/gRPC server setup; not on by default
Background location permission is required for boot/start; consider privacy implications
Logging is limited to currently connected protocols; not all protocols logged simultaneously

Description
The Network Survey Android App provides a basic survey capability for logging and analyzing Cellular networks, Wi-Fi networks, Bluetooth Devices, and GNSS constellations. Capture detailed records of signal strength, network information, and device data. All data can be conveniently logged to GeoPackage or CSV files for offline analysis. Alternatively, choose to live stream the data via MQTT or gRPC protocols for real-time monitoring and integration with other systems.
This app has the ability to access your device's location in the background. The background location permission is needed to start Network Survey at boot. More information can be found in the App's privacy policy located at https://www.networksurvey.app/privacy-policy
The cellular logging feature logs several details about the current serving cell, and then some basic information about the neighbor cells. This app won't log all 5 cellular protocols at once. Instead, it will only log information about the protocols that are current connected. If logging for one specific protocol is desired, then the phone must be locked to that protocol (try using *#*#4636#*#* from the dial pad).
The cellular survey records can be streamed to either a gRPC server or a MQTT broker. This is not on by default and a gRPC server or MQTT Broker needs to be setup for this feature to work.
See https://github.com/christianrowlands/network-survey-messaging for more details on setting up a network survey gRPC server.
See https://mosquitto.org for information on setting up a MQTT Broker.
A bonus feature of this app is its ability to create a Call Detail Record (CDR) file. If enabled, CDR events are logged to a CSV file.
The app also has a calculator that converts an LTE Cell ID to the corresponding eNodeB ID and Sector ID, and a calculator that converts an LTE PCI to the corresponding Primary Sync Sequence (PSS) and Secondary Sync Sequence (SSS).
I hope you enjoy this app as much as I have enjoyed writing it. If you have any feature requests please feel free to reach out by creating a GitHub issue at the link below.

Recent changes: * Added an AGC (signal strength) column to the GNSS Status screen. * More accurate satellite-usage tracking in GNSS logs. * Device Status logs now show the age of extra location fixes and flag when a location came from a mock provider. * Fixed the tower map sometimes showing no towers the first time it opens. * Added Slovak and Romanian translations, contributed by the community.

Need Wi-Fi local connected devices features to complete network survey along with open ports availability

Private open source. A bit complex to understand, but manual is good. Thank you developer. EDIT: Thank you. Maybe a "key" (labels on top row) regarding the .CSV file in the manual? I think I got it that the RSRP is the signal strength (as shown in Android in the SIM card settings). And signal Strength is the Raw signal strength? And serving cell "TRUE" I figured it out that it's the cell tower connected to, while False is the neighboring available cell signals. Thanks again.

1. Please include network survey for Wi-Fi for connected Wi-Fi devices ip address information along with open ports availability. 2. In keypad phones there was an option to display current are via mobile network only without mobile data using cell tower information. Please see to it if it's possible with Android phone. What I mean is can we get approximate area name using cell network information only?
