PhyR Impulse Noise Protection Technology Gains Support from Carriers and Equipment Providers to Enhance the Performance of IPTV Networks and Increase Service Coverage BRUSSELS, Belgium, Sept. 29

BRUSSELS, Belgium, Sept. 29 /PRNewswire-FirstCall/ — Broadband World
Forum 2008 — Broadcom Corporation (Nasdaq: BRCM), a global leader in
semiconductors for wired and wireless communications, today announced that its
innovative PhyR(TM) (pronounced “Fire”) impulse noise protection technology
has gained wide support from carriers and equipment vendors as the technically
preferred re-transmission technology.  Broadcom’s PhyR technology provides
several benefits over other application layer schemes and has proven to be a
robust and cost effective solution in “real-world” deployments to enhance the
performance of IPTV networks.  Broadcom will demonstrate its PhyR technology
at this week’s Broadband World Forum in Brussels, Belgium.

Broadcom(R) PhyR is an uncomplicated, easily provisioned, firmware upgrade
to the company’s xDSL chipsets and is based on physical layer re-transmission
technology (or PMS-TC) that enables carriers and equipment providers to
dramatically improve voice, data and video services to their customers, while
delivering as much as a ten-fold improvement in noise resilience.  As a
result, service providers are able to offer higher quality, more advanced
triple-play services for ADSL2+ and VDSL2 networks that equate to better
revenue opportunities with lower support and infrastructure costs.
Additionally, IPTV systems equipped with PhyR will enable end users to enjoy
improved network performance, better service coverage, fewer errors and an
overall heightened viewing experience.  Several early trials and deployments
of PhyR technology by carriers and telecommunications providers worldwide have
already provided several million customers with a better IPTV experience, and
offered additional revenue streams and lower support costs for operators.

To further the adoption of its PhyR technology, Broadcom is leading
efforts to standardize it, which will enable operators to deploy a standards-
based tool for their entire customer base that provides superior impulse noise
protection technology and leverages all of its benefits.

Traditionally, video services provisioned over copper loops have been
susceptible to noise sources in the ambient environment that limit the
coverage area over which services can be made available, or may even reduce
video quality by inducing “macro-blocking” or corrupted images.  Quality IPTV
deployments require carriers to provide a level of impulse noise protection
and margin that dictates an achievable data rate and the loop length over
which voice, video and data, or IPTV services, will be delivered.  While
traditional approaches for increasing noise protection have an improved effect
on residual errors, they unfortunately have an adverse effect on the
serviceable reach and data rate, thereby limiting the service coverage area.

“We are very pleased PhyR’s ability to address real deployment issues with
a greatly simplified provisioning model, better reach and significant
improvement in residual BER under heavy impulsive noise conditions,” said Greg
Fischer, Vice President & General Manager of Broadcom’s Carrier Access line of
business.  “PhyR technology offers our customers greatly improved ADSL2+ and
VDSL2-based video or data services, and provides new IP services in a way that
vastly improves performance while reducing service provisioning complexities
and scalability issues.  We are pleased to receive very positive technical
feedback from carriers and system vendors worldwide and through our
standardization efforts; we hope that this technology can benefit the entire
industry.”

Broadcom’s new and previously deployed central office (CO) and customer
premises equipment (CPE) system-on-a-chip (SoC) solutions are all upgradeable
to the innovative PhyR firmware.  As a result, service providers will be able
to offer IPTV and other ultra high bandwidth applications utilizing simplified
provisioning with quality levels comparable to Ethernet, while leveraging
their existing copper plant infrastructures.
