One instructive bit of data is the typical downstream bandwidth of fixed networks compared to wireless networks.

At lower speeds one can make the argument that wireless is a substitute product, compared to fixed-line service, at speeds up to about 3 Mbps.

After that, fixed line service has a huge advantage. Of course, mobile bandwidth is increasing, with fourth generation networks. But fixed-line keeps growing as well, so the gap will remain.
