This study provides insight of the future upload and download bandwidth demand for residential broadband connections, by answering the following research question:
How will upload and download bandwidth change between now and 2020?
Dutch consultancy Dialogic and the Eindhoven University of Technology were commissioned by NLkabel and Cable Europe to carry out this study. Dialogic is an independent research consultancy, focused on innovation and specializing in telecommunications. The Eindhoven University of Technology is a large research and educational institute and has already collaborated with Dialogic on a variety of projects.
It is important to recognize that residential broadband speed demand has a very diverse character. Households vary considerably in their intensity of use, the type of applications they use their connection for, and the amount of traffic these applications generate. In this study, we address this diversity by differentiating between different categories of users and our overall outcomes are averages over these categories. While the development of the demand for upload speed is related to that of download speeds, their developmentsa are not necessarily identical. Among other things, download speeds are sometimes more critical to users as they are often "waiting" to consume content of use an applicationj, while they are typically less pressed when uploading data. However, down - and upload speeds are closely entwined.
In this study, a prospective quantitave model of bandwidth demand was developped in order to answer the research question.
