Okay, so not much changed in the physical size of the router, and there's no additional status lights. (Why less lights is better is beyond me)...Thanks.

I just hope they don't release a "Rev C" in January to confuse everyone!

Now that everyone will have a 5Ghz radio...will they be switching entirely to that? In my experience (albeit limited) the range of 5Ghz is pretty poor but the speed and reliability seem great. Considering the field is a fairly small area, and that there will be a lot less happening on the 5Ghz band in most cases, that could be good...I trust they've taken this all into consideration.

Rev A supported 5 GHz as well. In fact, the field has used 5GHz for a couple of years now.

The Einstein report highlighted the "Failed Client Authorization" on page 7/8. Notably, they tried 5 different access points (including Rev B), and only Rev A was susceptible to the FCA attempt. Switching everyone to Rev B should help with this.

Ah, thank you for pointing that out. I did read the Einstein report but it's been a while. Any thoughts on why there always seems to be a request for all mobile hotspots to be turned off? Those typically run on 2.4 and wouldn't interfere with a 5Ghz field.

You answered your own question... "typically" isn't good enough. Having a single team create a mobile hotspot on 5 GHz could be enough to disrupt play. Likewise, having laptops that support 5GHz attempting to create local networks could cause issues as well.

It's generally considered better in situations like this to put a blanket ban out there instead of trusting everyone present to be able to know the difference. Simply removing as many possible points of failure is just good practice, and one of those points of failure is the audiences knowledge of wireless devices.

Of note, At the last off-season event I was at, my new 5 GHz iPhone 5 could detect the field AP, while older devices without 5GHz could not (I looked out of curiosity after reading the Einstein report, though I made no attempts to access the field with it!).

Indeed. For the same reason that Apple, Microsoft etc now ask all attending press to disable their hotspots during press conferences/demos.

That's really interesting (naturally there are tons of people with iPhone 5's now so I hope everyone exercises GP and self restraint).

On another note...I wonder if there has been any talk to release an updated FMS Lite. At all of the non-official events I've been to, field problems are incredibly persistent, and I hope that the changes and improvements brought to official competitions can benefit off-season events as well.

California should soon (next year) have FMS for all the off season events. We used FMS Delta 2010 this year, it wasn't bad but the updated seasonal FMS would be awesome!

That's awesome news, thanks RC!
