Open the .mat file in Matlab, you will see a 4096 x 478 matrix: 
power level in dBm in 4096 channels, and 478 consecutive time slots.

Freq resolution: 244.140625 Hz (1MHz,4096 bins)
Time resolution: 249.8560 ms (each bin is the average power of 61 samples taken in 124.928ms.
total of 478 time period of 124.928ms = 120s = 2min)
