On Wednesday Nokia Seimens Networks (NSN) and mobilkom Austria demonstrated the world’s fastest data call on a mobile device using the vendor’s Internet High Speed Packet Access (I-HSPA) technology. The downlink speed reached a maximum of 10.1Mbps during the trial.
I-HSPA is designed for heavy data transmission and multimedia usage. The ‘flat architecture’ is a new architecture of 3G networks based on W-CDMA technology that allows the base station to be connected directly to the internet and eliminating Service GPRS Support Nodes (SGSNs) and Radio Network Controllers (RNCs).
