Are cellular networks near capacity?


Credit Suisse just released a survey showing that wireless networks are near capacity. The rise of digital content (movies, books, songs) has let to more people playing such content over the cellular airwaves. AT&T and Verizon have instituted data caps over the past couple of months, in response to the lack of capacity in their networks. Have you had internet problems with your mobile device that could be attributed to a capacity issue? Are the wireless carriers investing enough money in infrastructure to keep up with the growth of capacity-sapping 4G devices? Given that the cellular providers have been making fairly healthy profits, what's holding them back from adding more capacity?

The only problem I have with Verizon is that it doesn't work through rural parts of my state where they haven't planted enough towers.
