Croatian mobile operator VIPnet has begun an upgrade to dual-carrier (DC) HSPA+ technology, enabling theoretical download speeds of up to 42Mbps, initially in Osijek, the country’s fourth largest city by population. The Telekom Austria-backed cellco, which currently covers 17 Croatian cities with its HSPA+ (21Mbps) network, announced that a new USB modem will be available next week for users to take advantage of the new DC-driven data speeds. The company also began testing Long Term Evolution (LTE) technology on its existing network in October, aiming to meet demand from its mobile broadband users who now number almost 180,000. ‘Despite the challenging economic environment VIPnet maintains a stable level of investment and continues to invest in network development and innovation. This year’s significant increase in customers, and users of wireless broadband, are a clear indicator that we are on the right track,’ said Bernd Schmutterer, CFO at VIPnet.
