RICHARDSON, Texas and SUNNYVALE, California, October 12 /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.
