Here is a random internet search for DAP-1522 performance...
http://evergbitswitchdome.blogspot.c...t-gigabit.html
"I noticed that the orientation of the DIR-655 and DAP-1522 made a difference in reported signal strength and data rate as shown in the DIR-655 console. So to make things work, do not forget to run some experiments to determine the best position of the devices to get the best possible performance... I am purposely trying to get my wireless sharing of my neighbors, and DAP1522 unusable, and I'm not exaggerating, 30 meters away. To be honest, there are 3 (not often, natural wood) between the walls and DAP1522 laptop - but still 30 feet? On the other hand, it could be a major selling point of fear that your neighbors might steal your wireless signal? Just buy a DAP1522! If you have a big house, or coverage area, is not going to cut it. But if you live in a small apartment, this thing is perfect."
The FRC competition field is a much more hostile environment than a typical apartment.
As far as I know, FIRST did not explicitly warn competitors this year that the new radio was weaker than in previous years. My guess is suboptimal radio placement on the robot that worked (well enough) in previous years does not work in a useable fashion with the DAP-1522.
Does anyone have any actual signal strength graphs as a function of orientation comparing the 2011 radio to the 2010 or earlier radio?
