Defining a Connectivity USO - services to be supported.
This page is a work in progress. It aims to provide a working definition of the services to be supported by a Universal Broadband service. These are the opinion of an avid user with some knowledge of how todays services work.
In defining a Universal Service for Broadband, you first need to decide what services are to be included, what sort of performance is needed and what the costs will be! The table below is a first guess at the most popular applications, the bandwidth and the quality needed to support each application. Such a table needs agreeing to implement a Broadband USO independent of whether the services are delivered on copper, radio, fibre or a combination thereof!
The user experience is determined by the underlying connectivity and how those resources are used to deliver outcomes desired. The need for speed once above a certain threshold and performance becomes a function of how many of these of applications can be run simultaniously. A Universal Broadband service cannot just be a best effort service as it is to be used to support key public services like healthcare in the home. Some of the applications need to be assured. The good news is that this is do-able even with todays Broadband access networks. What needs assuring and the nature of that assurance needs to be agreed.

This table is not definitive nor meant to be but provides a guide as to the sort services and performances customers are using and needing everyday. Some need to be assured some do not, but the end user experience cannot be random.
