This article focuses on some technology options that can beef up the upstream capacity of cable broad band. One classic method to boost individual users' bandwidth allotment is to subdivide nodes-the smaller number of customer per node, the more bandwidth for each user. Another technology that has promised greater upstream capacity for some time is DOCSIS 2.0, although it has had a bumpy start. DOCSIS 2.0 offers a return path boost because its options for S-CDMA or A-TDMA transmission schemes help shield data in the notoriously noisy return path frequencies.

Furthermore, having a large number of homogeneous cores may not be effective for all the applications. For instance,...
