Abstract
Generating a radio frequency test signal for a mobile wireless communication device from a set of scanned radio frequency data that represents a plurality of radio frequency channels over a sequence of time intervals. A segment of the set of scanned radio frequency data over a time interval is classified into one of several radio frequency environments. A subset of the segment of scanned radio frequency data is selected based on the classified radio frequency environment. A segment of the radio frequency test signal is generated using the selected subset of scanned radio frequency data. The steps of classifying, selecting and generating are repeated for each time interval in the sequence of time intervals. Classifying the segment of scanned radio frequency data into a radio frequency environment includes comparing a set of statistics extracted from the segment of scanned radio frequency data to pre-defined classification ranges.
