4G Americas white paper provides detailed information on the status of IMT-Advanced, on 3GPP Rel-10 including HSPA+ enhancements and the introduction of LTE-Advanced, and the planning for Rel-11 and beyond. 

Additional information on Rel-9 is included in Appendix B  and includes a complete update to Section 6 of the 3G Americas white paper, 3GPP Mobile Broadband Innovation path to 4G: Release 9, Release 10 and Beyond-HSPA+, LTE/SAE and LTE-Advanced, which was published in February 2010 (and therefore did not contain some additional changes to the standards before their publication in March 2010). This paper has been prepared by a working group of 4G Americas' member companies and the  material represents the combined efforts of many leading experts from 4G Americas’ membership.
