RF Signal Tracker - The RF Signal Tracker is an engineering application for doing impromptu hand-held drive-tests with your Android phone. You can monitor the RSSI (received signal strength indication) for the phone as well as the serving cell locations, describe the cell site's zone of coverage, and save or playback that data. 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, and analyze those stats in a meaningful way.
Google or OpenCellID location services are spotty at best -- Google's unsupported service is primarily for 2G GSM sites with less accurate 3G locations. In this app, site locations are only guaranteed to show if the sites are loaded into the devices database. A new feature 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. RF Signal Tracker features:
· Map and record your color coded signal strength as you travel.
· Users can redefine site locations on the map.
· Play back, pause, jump to any part of recorded data.
· Share current RSSI with Twitter, Facebook, whatever you can share with.
· Sector coverage zones describing sector orientation and beamwidth.
· One Cell Tracking to examine coverage of a single cell site.
· Sound and Vibration notification on handover.
· Possible handoff neighbors.
· User defined sites can be exported or imported for later use.
· Serving cell can be located through Google, OpenCellID.
· Sites located through Google or OpenCellID saved to local database.
· Export recorded data to XML, KML, 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 user
· Adjust GPS power settings
· App to SD card
