Packet Loss Spikes at 1 Minute Intervals

[jspatz1]

Like everyone else we are working to understand and minimize the potential for field communication troubles heading into Champs. As we watch the data packet charts we are noticing a peculiar pattern: Brief spikes of packet loss at exactly 1 minute intervals. The pattern is so repeatable our co-pilot can predict when it will occur by watching the chart, and the driver then confirms on cue a momentary loss of control. This jives with the driver's reports from some competition matches, when he briefly lost control "once or twice per match."

We use Labview. We have seen the same pattern while driving with two different computers, a Classmate and an Asus i5 laptop, both Windows 7.

Wondering if anyone else has seen this phenomenon, know its cause, or cares to speculate on the source of such a pattern. Our only guess is Windows activity.
