Taiwanese WiMAX operator Global Mobile has announced that it is planning to buy over 1,000 base transceiver stations (BTSs) to expand its WiMAX operations in the northern region of Taiwan, DigiTimes reports. The company is currently evaluating bids from three potential suppliers – Nokia Siemens Networks (NSN), Motorola and Huawei Technologies – for a supply contract worth about TWD2 billion (USD62.5 million). Global expects to award the contract at the end of February 2010. As reported by CommsUpdate on 4 January 2010, Global Mobile currently offers commercial WiMAX services in Hsinchu, stating at launch that it planned to spend an additional TWD3 billion on WiMAX infrastructure over the next three years as it expands its service. Global Mobile’s expansion plans will first see it launch services in parts of Taipei in the first quarter of 2010, aiming for ubiquitous coverage in the capital by year-end, before expanding into Taipei and Taoyuan Counties the following year.
