Report: Cable Ops Face Bandwidth Challenges

ABI Research's "Cable Operators' Service, Network, and Transformation Trends" report suggests that cable operators are facing stark choices about expanding bandwidth. Faced with growing competition in their core pay-TV business, cable operators worldwide are distracted by the all-digital transition regulatory deadlines imposed upon them by governing bodies, the available options for upgrading their network bandwidth, and the slow migration to an IP-based network for greater interactivity. Moving to 1 GHz networks is often the recommended alternative for network and bandwidth upgrading, but comes at a hefty first-year cost. The other alternatives have yearly capital and operational costs that are prohibitive over time.

Cable operators are mainly pursuing three avenues in their quest for greater bandwidth, although not all simultaneously. The first is reclaiming bandwidth via the analog-to-digital switchover now taking place in many countries. The second, switched digital video (SDV), that is expected to ramp up once the switchover is complete, brings channel-sharing benefits to downstream transmissions. The third, and considered the ultimate, option recommended by top-tier suppliers is a complete upgrade to 1 GHz networks. Cable operators are being very selective right now about how and where to invest in their networks and capabilities, while considering network-based and premises equipment-based (centralized and distributed) alternatives.
