Navini Announces Commercial Availability of 802.16e Mobile WiMAX(TM)

July 24, 2007

    RICHARDSON, Texas and PANAMA CITY, Panama, July 24
/Xinhua-PRNewswire/ -- Navini Networks today announced a
true milestone as it marks the first commercial
implementation of its 802.16e Mobile WiMAX(TM) software(1)
with beamforming.   The first deployment is in Panama City,
Panama, where operator Liberty Technologies has started
implementing Navini's software upgrade to convert their
network to 16e.

    "Navini has been a leader in personal broadband
for several years," explains Sai Subramanian, Vice
President, Product Management and Strategic Marketing,
Navini Networks.  "Some of the largest personal
broadband networks in the world already use Navini's
beamforming, which works extremely well to enhance service
delivery inside homes and offices.  We have been shipping
our Ripwave(R) MX8 16e hardware platform for over a year
and now the software is ready for commercial use.  Our
current customers can convert when they are ready and new
customers can deploy the 16e hardware and software starting
now.  We are very pleased with the results of our deployment
in Panama City -- which is an RF environment much harsher
than what the standards bodies have envisioned.  Being
commercial in the dense urban parts of Panama City proves
the robustness of the Navini solution."

    Navini's implementation of Mobile WiMAX(TM) with
beamforming technology is compliant with the IEEE
802.16e-2005 standard and ready for certification. Mobile
WiMAX promises broadband connectivity delivered anywhere,
anytime, combined with carrier economics that deliver a
viable business case.

    "We have now begun the process of upgrading our
pre-WiMAX network to Mobile WiMAX, and we already have
subscribers using the new software," said Samy Zayat,
Liberty's Chief Operating Officer.  "We have been
providing personal broadband services similar to Mobile
WiMAX using Navini's technology for a long time. WiMAX is a
standardization of what we have been operating for several
years. As we convert the rest of the network subscriber
modems already in customer service will be upgraded
over-the-air through a seamless software download." 
Liberty already has deployed a citywide network in Panama
City using Navini's pre-WiMAX technology, along with
WiMAX-capable base stations and subscriber devices in the
3.4 GHz frequency band.

    Navini will submit the Ripwave(R) MX base stations
supporting Mobile WiMAX(TM) for formal certification
testing by the WiMAX Forum once the certification labs are
open and available for 802.16e-based systems using these
profiles.
