40 results about "Bandwidth cap" patented technology

A data cap, often erroneously referred to as a bandwidth cap, is an artificial restriction imposed on the transfer of data over a network. In particular, it refers to policies imposed by an internet service provider in order to limit customers' usage of their services; typically, exceeding a data cap would require the subscriber to pay additional fees based on whether they have exceeded this limit. Implementation of a bandwidth cap is sometimes termed a fair access policy, fair usage policy, or usage-based billing by ISPs.
