Increasing cable bandwidth to retain high-value customers

Capital investment in local transmission infrastructure may help a cable-network operator to secure future Internet revenues

Internet provision via cable is carried in the channels not required for digital (or analogue) TV, and is inevitably a shared resource between all the households connected on a given segment. Unfortunately there is little or no brand loyalty for what is typically regarded as a commodity service. A heavy user will always prefer the fastest downlink and uplink speeds possible, and any moderately-active customer will quickly consider any available alternatives if contended bandwidth is too limited when they need it.

We have modelled the current infrastructure of a typical cable network operator, including Internet CPE, set-top box, optical node, amplifier and head-end, together with future options to address bandwidth limitations such as channel-bonding (if not already implemented), enhanced video compression, RF extension, and segment splitting. The specimen charts shown here illustrate the customer mix and dynamics in relation to available capacity in the network. According to readily adaptable estimates of the costs involved and the elasticity of relevant market segments (including level of competition), the full model compares the cost implications of implementing these upgrades with the potential revenue loss associated with not acting in a timely manner to retain customers.
