Business/Assignment Editors & High-Tech Writers

NetWorld+Interop 2002 Las Vegas

ADVISORY...for May 7-9

--(BUSINESS WIRE)

WHAT: Atheros Communications will demonstrate the state of the art in wireless
Local Area Networking (LAN) at NetWorld+Interop. Its Booth #549 will contain
five sections devoted to: combo IEEE 802.11a/g/b technology; advanced wireless
security; the use of OFDM at 2.4 GHz; a joint demonstration of 802.11a
interoperability with Cisco Systems, and a Customer Showcase highlighting
exciting new products from Atheros' growing list of partners. There will be
live product demonstrations at each of the first four sections, along with
reference designs and customer products on display. WHERE: NetWorld+Interop
Show, Las Vegas Convention Center, May 7-9 in Booth #549. SIGNIFICANCE: Atheros
Communications is the leading developer of networking technologies for secure,
high-performance wireless LANs. Its products are based on the IEEE 802.11
family of standards and use the company's unique "Radio-on-a-Chip" (RoC)
networking technology to deliver the fastest, most cost-effective, robust and
energy-efficient wireless LAN products in the industry. As the industry
innovator and market-share leader in wireless OFDM technology compliant with
the IEEE 802.11 specifications, Atheros is driving transparent connections
among electronic devices in the enterprise, home, public places (such as
airports, hotels, and universities), and on the road. Additionally, major new
customers will announce Atheros-based products at NetWorld+Interop.

DETAILS OF EXHIBITS AND DEMONSTRATIONS:

1.  Combo 802.11a/g/b Wireless LAN Chipset (AR5001X) -- This
    three-chip CMOS solution, introduced in March 2002, is the first
    to support all of the major IEEE 802.11 family of standards: the
    5-GHz 802.11a standard, the legacy 2.4-GHz 802.11b standard, and
    the OFDM enhancement for 2.4 GHz in the draft 802.11g standard.
    The product will be featured in a demonstration of seamless
    roaming between 802.11a and 802.11b networks. Other new products
    from Atheros that will be demonstrated for the first time at
    NetWorld+Interop include a Second-Generation 802.11a Chipset
    (AR5001A) enhanced to include support for advanced security,
    international features, increased network system capacity, higher
    integration to reduce costs, and even better performance than
    before; and an Integrated Enterprise-Quality Access Point Chipset
    (AR5001AP), the most highly integrated solution ever offered for
    wireless LAN access points at any frequency.

2.  Advanced Wireless Security -- The new Atheros chipsets feature a
    comprehensive security solution covering four key areas: Advanced
    Encryption Standard (AES) encryption, 802.1x Authentication,
    Virtual Private Networks (VPNs), and Virtual LANs (VLANs).

3.  "OFDM Everywhere" -- The IEEE has endorsed the broad adoption of
    OFDM (orthogonal frequency division multiplexing) for wireless
    LANs because of the higher speeds that result from its efficient
    use of spectrum and because of its resistance to multipath and
    other types of interference. Atheros believes strongly in the
    superiority of OFDM and therefore has made it the basis of its
    product-development strategy. Atheros will demonstrate OFDM at 5
    GHz (802.11a) and 2.4 GHz (draft 802.11g) at N+I.

4.  Atheros/Cisco Systems Interoperability -- Cisco and Atheros will
    demonstrate 802.11a interoperability between Cisco products and
    products based on silicon from Atheros Communications.

5.  Customer Showcase -- This exhibit will highlight new and existing
    products from Atheros' partners, including: Accton, Actiontec,
    ALPS, D-Link, Intel, Intermec, Linksys, Netgear, Philips, Proxim,
    SMC Networks, Sony, TDK, UltraDevices, and others.
