This would just be a single report if the resolution of the images in the Novarum document were not impaired. Image quality may have been limited by size
constraints on the document that was filed with the FCC. Better images of the report's graphics is in the other files.
The Novarum report is what the CPUC filed with the FCC that includes the most recent report on California's mobile broadband.
The trends slide shows the rate of improvement of cellular service over a two year period. This was the single slide I used at my talk at the October CCBC meeting in Seaside. This is an average over the entire state and may not reflect rural coverage.
The images file contains high resolution versions of the pictures in the report.
The powerpoint file contains adjusted coverage maps for the cellular carriers. The adjusted rates report
Advertised speed - one standard deviation
CPUC staff use their average measured speed as the advertised speed since cellular carriers generally don't specify speed the same way that their wireline brethern do. One way to think about this is: If the CPUC used the average, users could expect Internet performance that met the California target half the time. That is not what consumers expect. Shifting the measurement by one standard deviation allows the expection of meeting the service level to be raised to perhaps 80 percent. Making some allowance for availability of reliable service seems appropriate.
