Flexible MAC Architecture

David Claussen – FMA is a natural evolution of the existing DOCSIS infrastructures, with considerations to have new systems coexist with current systems. While not without a learning curve, FMA offers performance and flexibility to cable operators largely unavailable today.

Designing Future HFC Networks — 1.2 GHz and Beyond

Esteban Sandino – Extended spectrum DOCSIS or ESD represents the next evolution of HFC networks. It opens the door to RF spectrum expansion up to 1.8 GHz, as defined in the DOCSIS 4.0 specification

DOCSIS Time Protocol and Support of Wireless Access

By Charles Cook – Some cable operators plan to deploy their own wireless networks using existing DOCSIS infrastructure for backhaul. Accurate time frequency and phase are required in wireless base stations.

Energizing Your HFC Network for the Future

By Ron Wolfe – Wireless services are a significant part of our collective strategic initiatives, and it might seem daunting to envision adding several hundred watts of power consumption to over 100,000 nodes, but by taking advantage of voltage and ampacity increases,

DOCSIS 3.1 Profile Management Application

By Roger Stafford – Almost certainly, static PMA will yield the greatest step change in performance. Dynamic trims the network to take account of daily and hourly fluctuations in RxMER as seen at every modem.

Reflecting On the Past

By John Williams — Through necessity we learned to become more efficient when it comes to squeezing capacity out of the existing spectrum. We have been able to consistently increase our service offering to meet the insatiable demand of the customer by leveraging technology.

Extended Spectrum Beyond 1.2 GHz

By Nick Segura — Delightful lessons learned from past bandwidth expansion projects allowed operators to develop best practices which support anticipating and avoiding obstacles for future projects such as extended spectrum (ES) upgrades in the not so distant future.

What Problems Are We Trying To Solve With The Generic Access Platform?

By Matt Petersen — Do you ever run into new manufacturers trying to enter into the cable market and they just can’t figure out how to build a node enclosure to meet your expectations, let alone your specifications? Ever worked with an existing manufacturer and quickly realized that they struggled getting the new technology to fit into their existing enclosures?

The Next Generation of HFC Networks

By John Williams — Over the next several years you will see changes in how the cable industry will leverage HFC networks. As an industry we plan to leverage our coaxial cable networks for the long-term future.
