(Telecompaper) Netflix has opened up on how it limits bandwidth for customers on mobile networks. The company said it's implementing a default setting for mobile customers of streaming at about 600 Kbps, to help them avoid exceeding data caps. This means about 1 GB used for three hours of streaming video. Netflix said its testing showed this offers a good compromise between video quality and data usage. Customers will be able to adjust this in their settings if they want to to stream at higher bit rates and use more data.
