What is HSPA?
Part of the WCDMA evolution, HSPA (High Speed Packet Access) is a combination of HSDPA in the downlink and Enhanced Uplink in the uplink, both of which are specified in 3GPP Release 5/6. HSPA provides data rates up to 14 Mbps in the downlink and 5.8 Mbps in the uplink. The faster data speeds made possible with HSPA evolution will enhance the user experience for services like Mobile Broadband and Mobile TV while reducing the production cost per gigabyte.
Some vendors already developed this technology. Ericsson performed the world’s first (High Speed Packet Access) HSPA demonstration with Multiple Input Multiple Output (MIMO) technology during the CTIA Wireless 2006 event April 5-7 in Las Vegas (Stand #2624, Las Vegas Convention Center). The demo is based on Ericsson’s commercial Radio Base Station. HSPA with MIMO can double the speed in the downlink up to 28 Mbps.
Nokia HSPA can be added at minimum cost to an existing Nokia WCDMA platform by simply uploading software - no site visits means virtually no costs. Also Nokia transmission solutions ensure that the service delivery with Nokia HSPA is cost optimized end-to-end. Costs are also kept under control by enhanced Nokia radio resource management functionality, taking full use of an operators’ HSDPA, WCDMA R99 and GSM/EDGE capacity.
Nokia HSPA is made up of two key technologies, HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access), offering breakthrough data speeds theoretically up to 14.4 Mbps in the downlink and up to 3.6 Mbps in the uplink.
