Well, for the U.S. market, and there -- it tends to be a more advanced market than the rest of the world, meaning that the operators have more experience in -- also access to more finance vehicles. I think the price point of the airFiber X at sub-$400 gives them the absolute best price-performance backhaul that's ever existed. And that product has been shipping with full, 5 gigahertz, UNI-1, UNI-2, UNI-3 certifications from the start. So anybody in the market can deploy a new backhaul link, I don't think there's any reason to choose anything else than an airFiber X. Now we have been later than I hoped, in getting UNI-1, UNI-2, UNI-3 certifications for our existing airMAX radios, but that's a little more complicated because those radios have a prior set of rules. They were certified under what's called DTS. And it's not so easy to go back and take a DTS-certified device and then certify it for UNI-1, UNI-2, UNI-3. And to do that for a multiple family of products, but we have, and those, especially the RocketM5, and the PowerBeam, the high-end multi-point products, have already been certified. So we have been making progress, and I hope to have it all buttoned up in the next, well, let's say the next couple of months. But you also got to take a step back, and we have a global certification effort. In Europe for example, there is a new band that opened up, 57.25 to 58.75 for multi-point. And we've been rushing to get those certifications done, and those are just as important to the Europe market. But because the U.S. market is under a microscope, that's what you guys see. But the takeaway I want everybody to know is, yes, we're not happy with our progress in getting our airMAX family UNI-1, -2 to -3 certified, and it's not because we're being lazy. It's just -- it's a big task. And it's tackling a lot of products at once to go through this process. Some of it is under our control, some of it isn't. For example, the UNI-2 certifications have to sit in a queue with the FCC. That could be weeks or months sometimes.
