For both wired and wireless, it's time for legislation to address exactly what it and isn't permitted with regard to advertised speeds, throttling, and total usage -- both with respect to users, and with respect to peering.
It's not just an issue of policy, but one of transparency too.
It's a fact of life that more people will want to consume data than a network can support. So where are we going to make the cut? Diminish everyone's usage proportionally? Provide a guaranteed minimum? A minimum per minute, per hour, or per day? Prioritize traffic based on type? Implement caps? Allow people to pay for more speed, higher caps, or both?
Some of these will be better or worse for different users. But since people often have little or no choice over which carrier or ISP they use and switching can be expensive, this is exactly where it makes sense for policy to be made democratically, as with utilities. And publicized.
When I pay for a carrier, I want to know what I should be able to count on, and what I can't count on.
