Wimax Links And OFDM Overlay For HFC Networks: Mobility And Higher Us Capacity (2010)

By Ayham Al-Banna, ARRIS Group, Inc.

This article proposes a dual-approach solution to augment the US bandwidth in HFC networks. The solution is based on using OFDM channels over the existing cable plant and WiMAX channels over the air.

The proposed approach not only extends the US bandwidth, but also supports backward compatibility, smooth migration, efficient US bandwidth utilization, DOCSIS® 3.0 US channel bonding, load-balancing, US path redundancy, mobility, and. low cost and optimized implementation.
