Fierce IPTV reports that Cox is upgrading its network to 1 GHz across its entire customer base. As I’ve mentioned before, Motorola’s experience is that 1 GHz equipment (optical nodes, RF amplifiers, etc.) is very hot right now. Not that everyone needs the upgrade, but anyone with a network of 750 MHz or below (50-60% of cable operators in the US) is probably looking to go to 1 GHz for the extra bandwidth. And certainly no one is buying anything less than 1 GHz now for future deployments.
