Android app used to record and grade indoor LTE coverage. Below is a sequential flow of screenshots from an actual walk test. Our research paper describing the statistcal algorithm used for scoring and what the range of scores mean is in a research paper currently undergoing peer review.

Currently, the app lists and collects LTE data (RSRP, RSRQ, PCI, and timestamps) at a rate of twice per second and displays the values to the UI, as well as, records all the data into a CSV file stored externally on the device’s memory, then the app plots the data on a line graph or pie chart that is touch sensitive and can be scrolled, pinch-zoom, etc. Finally, the app does some basic statistics on the RSRP data and outputs a grade for that specific collection of data which is updated to the UI.

Thanks to A. C. for help with the UI/UX!
