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.
