Executive Summary

Broadband Access networks are constantly evolving to keep pace with ever growing subscriber demand. This comes at a significant cost for network operators. At the same time, network planners are faced with an increasingly complex set of factors that drive these changes from changing subscriber needs, emerging new technologies, challenging competitive landscape, and shifting regulatory requirements to name a few. In addition, long-term planning comes with additional challenges including numerous unknowns and assumptions which need to be evaluated. Many operators also maintain different networks as independent lines-of-business that are planned separately. Traditional planning tools and methods can no longer keep up with the complexity and pace of this change. Consequently, operators are often forced to take quick short-term tactical decisions that are not optimal in the long-term.

In this whitepaper we discuss these challenges and introduce a new tool called JibeTM which is specifically designed to enable network planners to model the evolution of their access network over an extended period, and quickly analyze the resource requirement and other impacts of these changes. It is designed to facilitate integrated planning of multiple networks. This will enable operators to quickly evaluate long-term impacts of network changes in a timely manner to make effective long-term strategic decisions

Executive Summary

An ever-growing array of access technology options are available to service providers to deliver state-of-the-art broadband service. With all these choices, service providers are faced with increasingly complex deployment decisions. Planning deployments with only a short-term view, or by using a simple blanket guidance, can lead to suboptimal results with regrettable investments in the long run. This is particularly true when planning for network expansion projects such as onboarding new greenfield areas. In this paper we have outlined a methodology to identify deployment choices that are optimal for your greenfield expansion plans, which can be seamlessly operationalized.

Executive Summary

Broadband service trends have gone through a significant evolution and there is no sign of this slowing down. In the early days of the internet all interactive applications were text based and file-sharing was considered a background task! Since then waves of innovation and application adoption have pushed subscriber demand.

A first evolution wave hit in the 1990’s with the introduction of search engines and multi-media browsers. In the early 2000’s distributed file and content sharing dominated demand, taken over quickly in the late 2000’s by broadcast and over the top video streaming combined with the upsurge of social media. The latest connected living innovation cycle – driven by the Internet of things and real time cloud-based applications – propels the need for both upstream and downstream bandwidth[1]. The impact of the broadband service evolution is considered the trigger for the third industrial revolution[2].

As a result, overwhelming pressure is put on a service providers access network to keep up with this steep broadband demand curve. Luckily the broadband service innovation is balanced by an equally if not faster technology innovation cycle.

This paper focuses on the technical evolution of the access network. It describes methodologies to evolve the capacity of an access network and how these methodologies are applied in copper, fiber and wireless networks. We will explain the similarities in transformation strategies of multiple access technology families and how to plan for an increasingly hybrid and converged access network.
