in Whitepaper, 3G Americas, IMT-Advanced, LTE-Advanced, 4G, HSPA, LTE

This Rysavy’s report explains and analyzes the evolution of EDGE, HSPA enhancements, 3GPP LTE, the capabilities of these technologies and their position relative to other primary competing technologies. It also highlights how these technologies fit into the ITU roadmap that leads to IMT-Advanced.

 The following are some of the key observations and conclusions of the white paper:

  • GSM-HSPA has an overwhelming global position in terms of subscribers, deployment, and services
  • 3GPP has spearheaded enhancements to both the Radio Access Network and Core Network to enhance customer experiences
  • HSPA and LTE have significant economic advantages over other wireless technologies because of their vast economies of scale and scope
  • The 3GPP OFDMA approach used in LTE matches or exceeds the capabilities of any other OFDMA system
  • 3GPP has made significant progress on how to enhance LTE to meet the requirements of IMT-Advanced
  • Specifications for LTE-Advanced, with peak theoretical speeds up to 1 Gbps, are expected to be completed by March 2011 making LTE-Advanced one of the first technologies defined to meet ITU IMT-Advanced requirements
