When enabled, tracks the frequency of network transmissions
(inbound and outbound) and buckets them accordingly.
Buckets are determined by time between network activity.
Each bucket represents the number of network transmisions that were
N sec or longer apart. Where N is defined as 1 << bucket index.
This network pattern tracking is particularly useful for wireless
networks (ie: 3G) where batching network activity closely together
is more power efficient than far apart.
