This report presents a technical analysis of HSPA+ technology as well as issues surrounding the refarming of WCDMA at 900MHz,A significant number of mobile operators will be upgrading from HSPDA to HSPA+ technology as an interim stop gap before eventually migrating to LTE, according to the latest report from EJL Wireless Research titled '3GPP Release 7 HSPA+ (Evolved HSPA) Network Migration Analysis.' 'LTE technology remains on the longer term horizon but HSPA+ is here and now. The increase of UMTS downlink speeds of up to 21Mbps peak will significantly improve the consumer's mobile broadband experience.While mobile operators are migrating towards Evolved HSPA (HSPA+), many questions remain: How will operators implement 64-QAM and MIMO in HSPA+ Node B sites' How will UMTS/WCDMA be implemented through spectrum refarming' We have completed a detailed technical analysis on both issues, highlighting opportunities for suppliers to benefit from this migration,' said founder and President, Earl Lum. 'Given the economic uncertainty through 2009 and 2010, it is clear that mobile operators will upgrade to HSPA+ technology during 2009-2011. Furthermore, the drive for higher spectral efficiency will mean that mobile operators need to begin planning on CAPEX for 900MHz refarming during this timeframe,' said Lum.The report includes detailed analysis for the following mobile equipment vendors: Alcatel-Lucent, Ericsson, Huawei Technologies, NEC, Nokia Siemens Networks, and ZTE. Detailed block diagrams for RF filters, duplexers, multicarrier power amplifiers (MCPA's) and antennas are included.

3GPP Release 7 HSPA+ (Evolved HSPA) Network Migration Analysis
Published on January 2009
Report Summary
This report presents a technical analysis of HSPA+ technology as well as issues surrounding the refarming of WCDMA at 900MHz,
A significant number of mobile operators will be upgrading from HSPDA to HSPA+ technology as an interim stop gap before
eventually migrating to LTE, according to the latest report from EJL Wireless Research titled '3GPP Release 7 HSPA+ (Evolved
HSPA) Network Migration Analysis.' 'LTE technology remains on the longer term horizon but HSPA+ is here and now. The increase of
UMTS downlink speeds of up to 21Mbps peak will significantly improve the consumer's mobile broadband experience.
While mobile operators are migrating towards Evolved HSPA (HSPA+), many questions remain: How will operators implement
64-QAM and MIMO in HSPA+ Node B sites' How will UMTS/WCDMA be implemented through spectrum refarming' We have
completed a detailed technical analysis on both issues, highlighting opportunities for suppliers to benefit from this migration,' said
founder and President, Earl Lum. 'Given the economic uncertainty through 2009 and 2010, it is clear that mobile operators will
upgrade to HSPA+ technology during 2009-2011. Furthermore, the drive for higher spectral efficiency will mean that mobile operators
need to begin planning on CAPEX for 900MHz refarming during this timeframe,' said Lum.
The report includes detailed analysis for the following mobile equipment vendors: Alcatel-Lucent, Ericsson, Huawei Technologies,

and antennas are included.
