Signaltest

This application is a software mainly for testing the wireless module of Android devices. Including Telephony (SIM card), GPS, WIFI and so on.

1. "SIM card test" can provide some convenience for some field test, network optimization and other related test work.
1). View the information of wireless cellular mobile network in real time: various information under 5G/4G/3G/2G such as signal strength, signal quality, signal-to-noise ratio SINR, cell information Cell ID, location update LAC, TAC, carrier frequency Earfcn , arfcn, band, various standard NR/TD-LTE/FDD-LTE/WCDMA/GSM information.
2). Monitoring network changes: 5G/4G/3G/2G network mode switching, offline, routing area update, intra-system intra-frequency cell reselection, intra-system inter-frequency cell reselection, NR/TD-LTE/FDD-LTE , FDD-LTE/WCDMA, WCDMA/GSM and other systems reselection, handover, redirection, etc. It is also possible to set a ringtone reminder when the above occurs.
3). Save the data and form a data statistical report: the number of signal strength intervals under 5G/4G/3G/2G, the statistics and filtering of the average value. The presentation of the intensity curve graph and the intensity interval ratio graph. Filtering of network mode switching, cell switching, and intra-frequency/inter-frequency switching. Search and filter for each signal, SINR, frequency Arfcn, and Band.
4). Simultaneous recording of test locations/routes. You can view the location where valuable information occurred on the network at that time (such as a weak signal area, 5G/4G switching, special frequency band, same-frequency cell switching, etc.), and the location is displayed on the map.
5). Test data saving or sharing. Even after the app is uninstalled and reinstalled, after re-importing the data, you can review it at any time.

2. "GPS test" is the detection of the positioning capability of the device, including the cold/hot start of GPS and AGPS, the ability to search for satellites, the accuracy test, the number of satellites, the type, the signal quality, the problem of lost stars, and the track record.
1). View current location information in real time: latitude and longitude, TTFF, positioning method, satellite signal strength Cn0, number of satellites, satellite type (US GPS, European Galileo, China Beidou BDS, Russia GLONASS, Japan GZSS, India IRNSS), accuracy (horizontal /Vertical Accuracy), Altitude, Velocity, Bearing, Altitude (MSL), Velocity Accuracy, Bearing Accuracy, PDOP, H/V DOP, etc.
2). Monitor positioning success/failure, star loss, etc. Draw a satellite azimuth map. NMEA logs can be recorded. CEP positioning accuracy test can be performed.
3). Save the data and form a data statistical report.
4). Simultaneous recording of test locations/routes.
5). Test data saving or sharing.

3. "WIFI Test"
1). View connected WIFI information in real time: signal strength, channel, frequency band, bandwidth, frequency, frequency range, device IP, connection speed, router IP, MASK, DNS. Monitor WIFI disconnection.
2). It can scan the surrounding WIFI information, signal strength, channel, frequency, bandwidth, distance, etc. in real time. The WIFI channel map can be presented, the channel quality can be measured, and the channel with less interference can be found. Internet speed test available.

4. "More Tests"
It includes some practical tools, such as ping test, bulk filling, batch file generation, QR code generation, network speed test, simulated positioning, etc.
