Chris Bowick, Cox’s senior vice president of engineering and chief technology officer, said the ambitious plans was aimed at moving Cox into the 2010 service world, a place that will require far more bandwidth and diversity of content. . . Starting in the last mile, bigger bandwidth is in the offing by cutting down on the size of nodes serving individual homes and boosting the overall plant capacity to 1 Gigahertz. At present Cox’s node size is about 620 homes offering between 750 and 860 Megahertz of total bandwidth. Cox’s plan is to move its plant nationwide to 1 Gigahertz capacity – the first major MSO to take that step – and cut node size down to 310 homes initially. Eventually, the node size will reach a maximum 250 homes, Bowick said.
