Fujitsu and Navini Show Industry's First Interoperability Demonstration Using Beamformed Mobile WiMAX(TM)

Fujitsu and Navini Show Industry's First Interoperability Demonstration Using Beamformed Mobile WiMAX(TM)

October 12, 2007

    RICHARDSON, Texas and SUNNYVALE, Calif., Oct. 12
/Xinhua-PRNewswire/ -- Navini Networks and Fujitsu
Microelectronics America, Inc. (FMA) announced today the
first demonstration of multi-vendor interoperability using
Smart WiMAX technology -- the conjunction of smart
beamforming with Multiple Input/Multiple Output (MIMO) on a
Mobile WiMAX (802.16e) network. Smart WiMAX systems will
provide an estimated doubling of system capacity, while
offering up to twice the coverage of simple WiMAX networks
in a fully mobile setting.

    The demonstration, the first in the industry between
two different vendors, took place in Navini's test facility
in Richardson, Texas, using Navini's Ripwave(R) MX8 base
station running Mobile WiMAX software and a CPE reference
design prototype based on the Fujitsu MB86K21 802.16e-2005
Mobile WiMAX chip. Smart WiMAX beamformed connectivity was
achieved using "dedicated pilots," a mandatory
feature for all Wave 2 Mobile Station subscriber devices
required for certification under published WiMAX Forum
profiles.

    Navini's Ripwave base stations combine the coverage and
capacity benefits of beamforming with the robustness and
throughput enhancements of MIMO. Navini's combination of
standards-based beamforming with MIMO is called Smart
WiMAX. Navini is working with partners such as Fujitsu to
extend the capabilities of Smart WiMAX to include
beamformed MIMO, which can double received data rates and
improve the reliability of a mobile signal.  

    "Navini, with others, led the inclusion of
beamforming and beamforming plus MIMO into the profiles for
Mobile WiMAX interoperability testing," explained Sai
Subramanian, VP Product Management and Strategic Marketing,
Navini Networks. "Showing multi-vendor interoperability
underlines our standards-based approach to delivering the
highest performance possible of Mobile WiMAX."

    "Navini and Fujitsu are the technology leaders in
beamformed MIMO," said Makoto Awaga, General Manager
of the Mobile Solution Division at the Electronics Devices
Group of Fujitsu Limited. "Subscriber modems using the
Fujitsu MB86K21 will use this advanced technology to offer
the best possible performance when using Mobile
WiMAX." 

    While the Smart WiMAX concept was developed by Navini,
the technology is standardized and can be implemented by
any vendor, as demonstrated by this collaboration with
Fujitsu.
