Interval Data Collection

August 14, 2012

CIMM DEFINITION: The frequency with which data is collected from the home. Data is often collected hourly or at fifteen minute intervals, depending on storage capabilities. Finer resolution or more frequent data collection requires systems that will not crash or bog down. May also be impacted by stress or activity on the meter or unit.

NOTE – Different operators have differing systems and can store varying amounts of data for varying amounts of time.

NOTE – Within the digital cable environment, the limited bandwidth of the out-of-band return path (a.k.a. backchannel) has the greatest impact on the interval of data collection. The technology exists to store up to 7 days of second-by-second measurement data on even the least capable legacy Set-Top Boxes, so neither storage nor resolution need be an issue.
