The biggest benefit to VDSL is a more consistent Internet experience. You'll be able to download (and upload) stuff from the Internet on average three times faster (and even up to ten times faster!) as a standard ADSL/ADSL2+ connection - even with the whole family or flat online! The closer you are to your nearest exchange, the better the service.
In some areas, Ultra-VDSL will be available where Ultra-Fibre is not. This could be for the short-term or the long-term. Depending on where you live, you could be waiting all the way up to 2019 to get a fibre connection!
Ultra-VDSL takes a much shorter time to install than Ultra-Fibre. On average, the installation time for Ultra-VDSL is within one day. From sign up to connection is generally within 5 to 10 working days.
Ultra-VDSL is a smart technology, and dynamically fine-tunes the speed and stability of your connection. This is called Dynamic Line Management, and it is not available on ADSL broadband.
