CellMapper is an application used to both map out and view cell phone provider coverage. It does this by collecting data via crowd-sourcing while you use the application (opt-in). Once data is received by the server, it will take a few hours to update.Since the application is used by many users, chances are network map for your provider are already available under the "Map" and the CellMapper main site. CellMapper also provides an offline, locally calculated, map if you do not wish to submit anonymous network information. If you change your mind, you can always upload this data at a later date.CellMapper works on both tablets (with or without radio) and cell phone. The map is available in Android 2.2 and later due to Maps API only supporting this version of Android or later.Features- Displays map of mapped (or calculated) towers, and currently connected tower- Displays advanced CellID info (LTE: RSRP, RSRQ, SNR, CQI, Timing Advance for LTE-TDD.
