Concept: The above
monthly profile chart shows the typical bandwidth usage for T-1
access by a customer. Note that use of the T-1 is highest during
normal business hours. The lack of use during evening and early
morning hours is factored in to the monthly "mean sustained
average" billing method, thus decreasing the cost. Although the
customer in this case often uses 500Kb to 1Mb "bursts" of
bandwidth, the mean sustained average for the month is only 96.5
Kb, because the low Internet activity during weekends and evening
hours was balanced against the high activity during business
hours. Other Internet providers charge by taking an average of the
usage peaks to calculate your monthly charges. If monthly access
was calculated using their method, your monthly bill would be much
higher.
Example: Using the
"Peak Usage" of 800.2 kb/s, the cost of this month of access would
be about $1,250.00 at other Internet companies who charge a "flat
fee" for a T-1, no matter how much bandwidth you actually use..
But using Dexter
Wireless's innovative "mean
sustained average" formula, the access charge for a typical
customer would fall into the 0 - 256k/mth rate group of $400/mth).
A savings of over
$800.00/month.
