Singaporean mobile operator StarHub has picked Huawei Technologies of China to expand and upgrade its national 3.5G mobile network with high speed packet access plus (HSPA+) technology by Q2 2009, to provide users with an enhanced mobile service offering improved indoor and outdoor coverage. HSPA+ will up the cellco’s current maximum mobile broadband speeds from 14.4Mbps to 21Mbps (downlink), and increase uplink capability from 1.9Mbps to 11Mbps. In addition, StarHub says it plans to expand its mobile base station capacity to at least 3,500 base stations in support of its 1.8 million mobile subscriber base. The expansion deal is part of StarHub’s SGD200 million (USD147.2 million) enhancement of its 3G/3.5G network to support higher downlink and uplink speeds. To complement the upgrade, the operator is redesigning its backhaul infrastructure capability and international links to enhance its current high speed fixed and mobile broadband throughputs.
