NII Holdings Has Selected Huawei as Its 3G W-CDMA Supplier in Mexico and Brazil / Selected to develop and provide W-CDMA-based networks and related services in Mexico and Brazil positioning NII to offer next-generation wireless services

BARCELONA, Spain, Feb. 15, 2011 /PRNewswire/ -- GLOBAL MOBILE WORLD CONGRESS -- Huawei, a leader in providing next generation telecommunications network solutions for operators around the world, and NII Holdings, Inc. , a leading provider of mobile communication services operating under the NEXTEL brand in Latin America, announced that Huawei has been selected to provide equipment and related services for new W-CDMA networks for NII subsidiaries in Mexico and Brazil.

Under the contemplated agreements, Huawei will use its expertise to provide end-to-end W-CDMA solutions to build Nextel Brazil and Nextel Mexico's W-CDMA networks on recently acquired 3G spectrum licenses in Mexico and 3G spectrum for which Nextel Brazil has successfully bid in Brazil. It is contemplated that Huawei will develop and deliver the core network, radio access network (RAN) and backhaul, all of which will be customized for NII's Push-to-Talk service.

NII's decision to once again select Huawei as a supplier derives from its successful venture in 2009 to build W-CDMA networks for Nextel Peru and its ongoing deployment for Nextel Chile.

"Partnering with technology leader Huawei on the development of our 3G network deployments in Brazil and Mexico will enable us to continue to deliver on the differentiated wireless communications offerings our customers have come to expect. We will provide our customers in those markets with next-generation wireless service offerings. Selecting Huawei as our 3G network supplier is a significant step in bringing high-quality and efficient 3G communication services to our customers. Our expanded relationship with Huawei demonstrates our commitment to our 3G strategy in Latin America and in Huawei's global infrastructure expertise," said Alan Strauss, EVP, Chief Technology Officer, NII Holdings.

"It is a great honor for Huawei to be selected as the supplier to assist in building NII's W-CDMA networks for its subsidiaries in Mexico and Brazil. We fully understand the importance of the loyalty and trust NII has placed in us. Huawei is committed to delivering outstanding W-CDMA networks in both Mexico and Brazil and will continue to support NII with the innovative technologies, creative applications and distinguished devices that support their competitive edge," said Eric Xu, EVP of Huawei.
