Last week, we learned from a leaked memo that Time Warner Cable is preparing to roll out usage-based broadband service tiers to new customers in Beaumont, TX. The company has since confirmed its plans, with monthly bandwidth caps set at 5GB, 10GB, 20GB, and 40GB. Customers who exceed their cap would be hit with an undetermined per-gigabyte charge, but Bell Canada's overage fees, which range from CAN$1.00 to CAN$7.50 per gigabyte, may give some inkling of where Time Warner's overage fees will end up.
I recommend reading this article in full, but it can be summed up by this passage:
All of that is to say that cable and DSL won't always be the only games in town. If wireless solutions are able to deliver on their promises of high speeds with no usage limits, capped cable broadband service like Time Warner has planned is likely to be unattractive, to say the least.
I can guarantee you that if they try to push that on me, I'll be subscribing to a new service.
