… it is worth continuing to ask whether the problem is solely, or even mostly, spectrum. The large wireless carriers could also increase the information-carrying capacity of their networks by building more towers and connecting them to fiber rather than copper wires. Today, even though 97.8 percent of the U.S. population has 3G coverage, more than 80 percent of cell sites are still connected to copper wires. But since the goal of any private company seeking Wall Street investment is to achieve the same levels of revenue (or more) while laying out less money, spending on “backhaul” (connections between towers and Internet access points) has not been a high priority. The problem in wireless transmission, therefore, is probably the wires and the towers, not spectrum. Executive compensation and quarterly results trump higher-quality service every time.

Comcast’s Catch-22 Position on SOPA

As noted by the folks over at Techdirt:

Just as NBC Universal and other SOPA supporters continue to insist that DNS redirect is completely compatible with DNSSEC… Comcast (and official SOPA/PIPA supporter) has rolled out DNSSEC, urged others to roll out DNSSEC and turned off its own DNS redirect system, stating clearly that DNS redirect is incompatible with DNSSEC, if you want to keep people secure. In the end, this certainly appears to suggest thatComcast is admitting that it cannot comply with SOPA/PIPA, even as the very same company is advocating for those laws.
