Pocket Wizard Paterns?

->> So as I read the piece in the SS newsletter on pocket wizards's patern function and how it works. Wouldn't that just bring down the pocketwizard functionality as in a large sporting events your would have the units producing lots of signals for longer amounts of time, thus stepping on the freq for longer periods of time? Can someone explain this to me, on how it works and how this makes things better? As Danny Ford used to say, "I'm no scientific rocket".

->> I received this update from Patrick Clow at LPA Designs this afternoon:
Right now, if you press and hold your TEST button or external button on a MultiMAX it is already sending out repeat triggers. Now imagine that multiple photographers are all pressing their TEST buttons at the same moment. Everyone’s triggers are going out at the same time. And they are repeating at the same time.Repeating is good because any trigger that gets through helps you. But being *simultaneous* is bad. Here’s my quick audio example. The names are repeating, but you can’t pick them out because they are simultaneous.

With Patterns enabled you get the benefit of repeat triggers, so even if that first one is simultaneous, the rest won’t be. In this example, you can pick out the names as they repeat:

If the receiver can hear its name, it will trigger! Does that make sense? My receiver’s name is Fred. It triggered. :-P

The audio examples are slow so we humans can process the idea. In MultiMAX RF triggering timeframes, this is all happening at the millisecond level – your MultiMAX sends repeating triggers over 30 times a second. Patterns helps make sure a trigger can get through by the first or second repeat so that you don’t miss the moment.

Additionally, without Patterns the receiver is sending out a confirmation signal for every trigger it receives. This adds to the clutter in the air, makes moments where the receiver isn’t listening (because it is transmitting a confirmation), and makes it harder for nearby receivers to hear their specific transmitter. With Patterns enabled on the receiver, confirmation does not happen: it spends more time listening and is more polite to its neighbors. More information on confirmation will be coming in the firmware release notes and will get added to the wiki.
