Comcast spreading its WiMAX wings

It was reported last week that the venture capital unit of cable TV provider Comcast, along with other firms, had been part of a $12.6 million seed investment in WiMAX-related start-up Cartiza Networks last year. It is not apparent how much of the round came from Comcast Interactive Capital; and, while the investment seems like old news, Cartiza has not said much more about its plans since then. The Littleton, Mass., company is believed to be developing content delivery and management technology for use over WiMAX networks.

A Comcast official also recently said the company is planning to use femtocells in conjunction with its WiMAX offering via the Clearwire venture. The femtocell plan and news of the Cartiza investment came to light not long after Comcast and other cable TV providers committed to invest in the new Clearwire WiMAX venture with Sprint. While Comcast's original residential wireless play with Sprint fizzled, it seems the cable giant now feels WiMAX is the right wireless path to take into customer homes.
