What is the downstream/Rx bandwidth range?

The downstream/Rx bandwidth range is typically defined as the frequencies used for receiving signals from a cable system to the customer's equipment, such as a modem or set-top box. In the context of cable telecommunications, the standard downstream bandwidth usually extends from 50 MHz up to 860 MHz. This range allows for a diverse array of services, including high-speed internet, cable television, and video on demand, while accommodating multiple channels across the spectrum.

The range of 50-860 MHz has been established as a balance between maximizing data rates and maintaining compatibility with existing infrastructure. It enables multiple digital channels to operate efficiently, which is essential for delivering high-quality video and internet service to consumers. Other options present incorrect ranges, as the lower ends are insufficient for the demands of current technologies, while the upper limits in some cases exceed practical or standard specifications currently utilized by the industry.
