- The telecommunication industry is capitalizing on continuous evolution of the HSPA (high speed packet access) broadband technology, which is implemented in the form of 3GPP Release 7, 8, and 9. The novel solutions effectively meets the increased demands for higher data rates and greater cell capacity driven by the success of the mobile broadband. The HSPA 3GPP Release 7 supports the higher order modulation, multiple input, multiple output (MIMO) technology in the downlink, data rates of up to 28Mbps in the downlink, and 11.5 Mbps in the uplinks. The features of HSGPA 3GPP Release 8 include multicarrier operation, higher order modulation combined with MIMO, and enhancements to common states, and integrated mobile broadcast. The technology facilitates the existing WCDMA operators a cost-effective way of broadcasting data through 5MHz of unpaired spectrum. The ongoing works to standardization 3GPP Release 9 focuses on the support of features that further increases bit rates.
