We continue to have nodes of about 500 homes passed-but that varies with density. It's really based on about a one-kilometer radius around the node. In the headend, we are generally combining four of those together, so as traffic goes up, it will be very easy to subdivide them back to 500 homes. It's also easy to further divide those 500-home nodes as needed. There are a lot of different ways that people characterize node sizes.
Some people use averages, some people use maximums.
We limit them to a maximum of 600 homes passed per laser. And we are experimenting with a few pilots of the LightWire architecture, which takes fiber down into nodes of about 70 homes passed, on average. We won't be doing it everywhere just because there's not enough equipment out there to support it. But we think it's a real solid architecture, and its advantages to us are reduced operating costs and fewer actives. In Salt Lake City, we have a 520-mile area that is about 100 percent designed.
