Mobilkom Austria has demonstrated the world’s fastest data call with a mobile device using the Internet HSPA (I-HSPA) solution from Nokia Siemens Networks. During the trial, the data transmission downlink speed reached up to 10.1 Mbps. The solution complies with the future network technology known as Long Term Evolution (LTE), supporting data rates of up to 173 Mbps. I-HSPA innovation by Nokia Siemens Networks introduces a flat network architecture to the 3G networks based on WCDMA technology by connecting the base station directly to the internet and enables cost-efficient scaling of the network. It works with all HSPA devices and improves end user experience by reducing latency. I-HSPA flat network architecture also enables smooth migration to LTE.
