Broadcom Adds Advanced Noise Cancellation Technique to DSL Gateways - First to Provide Bandwidth-Enhancing RNC Technology for Residential DSL

LONDON -- Broadband World Forum 2015 – Broadcom Corporation, a global innovation leader in semiconductor solutions for wired and wireless communications, announced a Reference Noise Cancellation (RNC) technology enabled by its BCM63138 family of devices. Broadcom is the first to offer telecom carriers the benefits of RNC to enhance the performance of DSL customer premise equipment (CPE) without the need to replace or upgrade installed ADSL or VDSL2 infrastructure equipment.

Broadcom's RNC implementation on its BCM63138 family of high-performance DSL SoCs for home gateways works with existing DSL infrastructure equipment, including single-line or bonded ADSL and VDSL. It also complements existing DSL performance techniques such as G.inp, and G.vector, and coexists independent of any other equipment in the network. By filtering out received noise on the subscriber line at the CPE in the residence, this advancement in DSL technology enables carriers to improve the quality of the received signal and deliver higher performing broadband to subscribers.

"Today's announcement builds on Broadcom's unmatched DSL portfolio, enabling operators to deliver high-bandwidth broadband services to meet growing consumer demand," said Greg Fischer, Broadcom Senior Vice President and General Manager, Broadband Carrier Access. "With the addition of RNC technology to Broadcom's BCM63138 SoC family, operators can deploy CPE that provide DSL subscribers with an unmatched performance improvement with no investment or change to existing installed infrastructure equipment."

Enhancing DSL networks by leveraging the existing installed base of copper networks is the most viable and cost effective option to installing new fiber. RNC reduces noise interference and provides DSL subscribers significant and measurable performance improvements for broadband applications.

Availability
Broadcom's BCM63138 is currently sampling. Broadcom will be demonstrating the solution at Broadband World Forum in London, October 20-22, 2015, Meeting Room #36.
