New 4G Americas whitepaper on HSPA evolution in 3GPP standards

Some forecasts put HSPA at over 3.5 billion subscribers by the end of 2016. Operators with HSPA and LTE infrastructure and users with HSPA and LTE multi-mode devices will be commonplace. There are 412 commercial deployments of HSPA in 157 countries, including 165 HSPA+ networks. Thus, with the continued deployment of LTE throughout the world, and the existing ubiquitous coverage of HSPA in the world, HSPA+ will continue to be enhanced through the 3GPP standards process to provide a seamless solution for operators as they upgrade their networks. While LTE, with 33 commercial deployments to date and over 250 commitments worldwide, will be the mobile broadband next generation technology of choice for HSPA, EV-DO, WiMAX and new wireless operators, HSPA will continue to be a pivotal technology in providing mobile broadband to subscribers.

The white paper explains that as 3GPP specifications evolve, their advanced features help to further the capabilities of today’s modern mobile broadband networks. With each release there have been improvements such as better cell edge performance, increased system efficiencies, higher peak data rates and an overall improved end-user experience. 3GPP feature evolution from Rel-7 to Rel-10 has pushed possible HSPA peak data rates from 14 Mbps to 168 Mbps. Continued enhancements in 3GPP Rel-11 will again double this capability to a possible peak data rate of 336 Mbps:
  • Rel-7: 64QAM or 2X2 MIMO => 21 or 28 Mbps
  • Rel-8: DC + 64QAM or 2X2 MIMO + 64QAM => 42 Mbps
  • Rel-9: DC + 2X2 MIMO + 64QAM => 84 Mbps
  • Rel-10: 4C + 2X2 MIMO + 64QAM => 168 Mbps
  • Rel-11: (8C or 4X4 MIMO) + 64QAM => 336 Mbps
“If operators are able to gain new additional harmonized spectrum from governments, they will no doubt deploy LTE, However, it is clear that HSPA+ technology is still exceptionally strong and will continue to provide operators with the capability to meet the exploding data usage demands of their customers in existing spectrum holdings,” Pearson said.
