Comcast Boosts Cable Upload Speeds

Comcast officially announced Tuesday what customers around the United States have been noticing for months: no bandwidth caps when uploading files less than 10MB. The feature, called PowerBoost, follows a similar upgrade in download speeds last year.

Customers will be able to upload at speeds reaching 2 megabits per second, far greater than the standard limit of 384 kilobytes. The service is being rolled out on a market-to-market basis, with the entire Comcast network expected to be upgraded by the end of the year. Comcast customers already see download speeds of 12Mbps to 16Mbps for files under 10MB.
