Unleashing The Upstream


According to the law of diminishing returns, adding more of a variable factor against a constant will, at some point, lead to a reduction in output.

It’s Economics 101 and also a good way to describe cable networks and the challenges that service providers face in delivering a higher quality of service using existing infrastructure.

It’s a challenge that we at Motorola have been focusing on for a long time, namely how to improve network performance without significantly impacting a service provider’s bottom line. Today, at the ANGA Cable expo in Cologne – we’re proud to announce a new upstream data transmission record for existing EuroDOCSIS® 3.0 networks.

The record of 288 Mbps for a 5-65MHz return path was set by transmitting across eleven return path channels of which four channels employed 256 QAM modulation, using the low-noise, high-dynamic range found within the Motorola RX48 return path receiver operating within a Motorola BSR 64000 Cable Modem Termination System (CMTS).

By increasing the available return path channels to eleven from the standard two or three – we’ve demonstrated how service providers can deliver richer residential and business services without having to significantly upgrade their network which is both costly and time consuming. Motorola is unleashing every last bit and byte of capacity out of the existing network.
Getting more out of what you’ve already got? Now that’s smart business.
