* * Transcript: So this is a planned view of our Enterprise test environment. Our Non-Line of Sight test consists of this AP that you see in the far left-hand bottom corner. Thats the location of the AP. And then we have these other stations, 40, 42, 46, 48 and 50 out here, that are the stations I was telling you about. We characterize those specific locations and we test our clients on these, in all modes, all channels. Some of these tests take up to 17 hours to run and we use the robots to do this because it would be painful for a human to be there for 17 hours pushing them around. So up here in the upper left-hand corner you can see station 40, 6 meters from the AP, no obstruction. Station 42 here, its 26 meters, it has two walls, one cube, 44, 34 meters, no walls, four cubes and so on. You get the idea. So weve characterized it insofar as the physical environment. And this is going to be real useful if we want to go and test the Legacy Beam Forming that you guys have coming down the line. Its very interesting and were going to test it out here first.
