Bandwidth Management
Meet the Bandwidth Crunch - Optimization and Expansion Options for Cable Operators

Here’s why you feel a bandwidth crunch:

• Simulcast of identical programming in both the analog and digital tier
• The growing popularity of HD
• A general growth in the number of channels available
• The rollout of commercial services
• A rise in high-speed data use

870 MHz cable systems are in the best position. Our estimates are that around 40 percent of North American systems are at this bandwidth level. Systems with 750 MHz, especially those in densely populated areas, are likely candidates for some of the options discussed here, and 550 MHz systems need help in a big way.

Scientific Atlanta has the extensive expertise, coupled with the products and people to help you deal with this challenge in both the near term and the future.
