Execute The Upstream Makeover Without Leaving Scars (2021)

By Dr. Robert Howald & Larry Wolcott, Comcast; Leslie Ellis, EllisEdits

This paper will describe the analysis, tools, techniques, and processes to enable this upstream bandwidth transformation, focusing on production operationalization of an 85 MHz Mid-Split including:

  • How homes may be impacted by a mix of device spectrum capabilities
  • Mid-Split activation using SC-QAM and OFDMA
  • Existing metrics and tools to assess home health New automation techniques to enable a seamless transition for customers with the activation of new upstream spectrum
  • Cross-functional tools and processes for Tech Ops, Care, and Serviceability
  • Identify and discuss some of the differences between Mid-Split and High Split (204 MHz), and of DOCSIS 4.0

Widening the upstream to stay ahead of heavy bidirectional consumption is a multi-dimensional topic. Readers will learn about new tools and operational practices that can smooth this transformation.
