Scarlet Awards First Caribbean Mobile WiMAX Network to Navini

March 22, 2007

Pioneering prepaid personal broadband services


    RICHARDSON, Texas, March 22 /Xinhua-PRNewswire/ --
Scarlet B.V., the Curacao international network operator,
has announced the upcoming conversion of Scarlet's current
Navini-based wireless broadband network to the Mobile WiMAX
802.16e standard and the introduction of new services on the
network.  The network is scheduled for upgrade in Q3 2007
improving network performance and increasing capacity.

    Scarlet has offered wireless broadband services in
Curacao since 2001, and in June 2005 launched its Scarlet
One(R) branded personal broadband service using the Navini
Ripwave(R) MX technology. In the past 6 months, Scarlet has
aggressively expanded its broadband network to keep up with
accelerating customer demand for reliable broadband service
that is portable, easy to install, and does not require a
fixed line phone.  Expansion will continue throughout 2007
and will be able to serve 10,000 customers.

    Mobile WiMAX is the new emerging global standard for
broadband wireless and is being introduced into the market
in phases. Navini Networks is on the leading edge of
rolling out Mobile WiMAX solutions.  

    With a software upgrade, Scarlet's current network will
be 802.16e standard (Wave 1) compliant.  The system will
come with Wave 2 beamforming capability via Navini's
trademark Smart WiMAX(TM). Navini's Smart WiMAX(TM) is the
innovative combination of mobile WiMAX with Navini's
patented Smart Beamforming & beamformed MIMO, which
enhances range and throughput performance.

    Scarlet's CEO, Eric E. Stakland commented, "We
believe the effects of convergence of broadband and
mobility will be substantial in the marketplace within two
years.  In our view, a broadband network with Mobile WiMAX
technology will be a stronger delivery platform for future
services than cellular will ever be."

    "We are delighted to provide Scarlet with the
technology to deliver these exciting new services,"
said Roger Dorf, Navini's President and CEO.  "As more
and more consumers experience personal broadband, the demand
will continue to grow.  Personal broadband is
irresistible."

    Scarlet is introducing new product and service
offerings in early 2007.  The new MyScarlet(R) VoIP service
includes a choice of unlimited calling to Netherlands
(fixed) or U.S./Canada at no additional cost for Scarlet
One subscribers.  Stakland explained, "Our enhanced
density of base stations, particularly in Curacao's
business centers, will support the increasing use of
Scarlet One in businesses and the use of PC cards for
portable broadband in laptops.  Our intention is to enable
business customers who are out of their office to remain
connected online wherever they are."

    Scarlet also offers prepaid Personal Broadband,
tailored to dial-up customers wanting higher performance
without paying more.  Robbert Willemsen, manager of
Scarlet's sales teams and its dial-up services, commented,
"Our dial-up customers average 40 to 50 guilders (USD
$22-$28) per month in phone charges, with many exceeding
100 guilders (USD $55) per month in addition to their
monthly subscription fees.  For customers using the
Internet for less than an hour per day, Prepaid Scarlet One
will save them money while doubling their connection
speed."
