During the trial, the data transmission downlink speed reached up to 10.1 Mbps, according to NSN.
The I-HSPA, which is also known as Evolved HSPA - a 3G mobile data protocol defined in 3GPP Release 7, introduces a flat network architecture to the 3G networks based on W-CDMA 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, supporting data rates of up to 173 Mbps.
