RF Signal Tracker

RF Signal Tracker is an engineering application for doing impromptu hand-held drive-tests with your Android phone. You can monitor the RF and WiFi signal strength as seen by the device as well as WiFi hotspots, describe a cell site's zone of coverage, identify changes in technology and handover points, and save and playback that data. Site locations can be loaded into a database via a CSV file or by long-pressing the map on a location to manually insert the site to the database. While many of the phone stats in the app can be displayed on the phone already (go to Settings -> About -> Status to see them). The advantage of this app is you can then map, record, analyze, and share that data in a meaningful way. App features: - Monitor data traffic bytes. - XY Chart of RF and WiFi signal strength over time. - Voice notification of signal strength & technology changes, handovers, open hotspots, and more! - Insert notes into the RF data collected. Notes can be viewed & edited in Big Picture - 'Drive Mode' screen showing just RSSI, Cell ID, and technology to view while driving - Localized for French, Spanish (thank you Augusto!), Portuguese, and German. - Map and record your color-coded RF signal strength as you travel. - Wardriving. Collect WiFi access points and list mobile location at the strongest signal. - Users can redefine site locations on the map. - Playback, pause, jump to any part of recorded data. - Share collected data and Maps with Twitter, Facebook, whatever you can share with. - Sector coverage zones describing sector orientation and beamwidth. - Sound and Vibration notification on handover. - User-defined sites can be exported or imported for later use. - A limited number of serving cells can be located through Google, OpenCellID. - All sites located through Google or OpenCellID saved to a local database. - Export recorded data to XML, KML (Google Earth), or CSV files. - Import older recorded data for playback. - Roaming and data states, data activity, CGI. - WiFi MAC address, BSSID, supplicant state. - WiFi network access points identified. - EIRP/ERP and Free Space Loss calculators - Big picture of entire drive test or site survey - Auto-shutoff at minimum battery level set by the user - Adjust GPS power settings - App to SD card *** Please keep those bug reports coming! If you crash and are given the option, please send in the report. I read them all. Or you can email directly at Type1apps@gmail.com Known Issues: - If a site appears off the coast of Africa it means that you are using Google's location service or OpenCellID and they cannot determine that cell's location (so it returns the location 0 deg Lat, 0 deg Lon). A new feature for version 2.2.9 is the ability to define your own site locations (add, move or remove) by pressing a spot on the map or a site icon. Users can do their own site surveys as they travel. This is a workaround for those who do not have access to site location data -- unless you are an engineer for a carrier, you won't have access to this data since site locations are generally considered proprietary. - Background recording, where you exit the app after you start recording, will not register signal strength changes if the phone is in sleep mode (screen is blank). This is a "bug" in Android not the app. If the phone is not allowed to sleep, background recording is possible. - BER, EVDO, SNR & Ec/Io may display -1. This is the number the Android OS is sending, sorry. - The app is optimized for GSM service. CDMA devices are not completely supported. This is due to the lack of a CDMA phone (and contract) on my part, not anything specific to the technology. So if you have a CDMA phone be aware it has not been tested by me. - Please remember you are using a phone, not a laptop. If you try to record hours worth of data, and/or play it back, unexpected things may happen.
