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:

What's New in 2.4.3:
· Big Picture display can now be filtered for handoffs, technology, and data activity as well as rssi. This allows the user view these changes graphically.

What's New in 2.4.2:
· Text To Speech (TTS) incorporated into Main and Map tabs. Voice notification of handoffs, technology change, open hotspots, etc. (see Preferences to activate and select language).

What's New in 2.3.2:
· Application now localized for French, Spanish, Portuguese, and German!
What's New in 2.3.1:
· Users can populate known cells within 2km of serving cell (Menu -> Load nearby sites).
· Cell site location optimization searches for sequential cell IDs within a given distance of each other and aligns their LAT/LONs. See (Menu -> List cell site records -> Menu -> Optimize site locations) in the Live tab.
· Cell IDs no longer overlap. Serving cell ID shown in red.
· Fixed display bug when viewing Big Picture from recorded data playback.
· Fixed list item focus in preferences screen.
