Report: HSPA+ Upgrade A ‘Stopgap’ To Eventual LTE
| 29 января 2009 |
According to the latest report from EJL Wireless Research, a significant number of wireless carriers will be upgrading from HSPDA to HSPA+ technology as an interim stopgap before eventually migrating to LTE.
"3GPP Release 7 HSPA+ (Evolved HSPA) Network Migration Analysis" features 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 (MCPAs) and antennas also are included.
"LTE technology remains on the longer-term horizon but HSPA+ is here and now. The increase of UMTS downlink speeds of up to 21 Mbps peak will significantly improve the consumer's mobile broadband experience,” says Earl Lum, founder and president of Calif.-based EJL Wireless Research who has 15 years of experience within the wireless industry, including eight years as an equity research analyst on Wall Street covering the global wireless industry. “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.”
He continues, "Given the economic uncertainty through 2009 and 2010, it is clear that mobile operators will upgrade to HSPA+ technology during 2009-11. Furthermore, the drive for higher spectral efficiency will mean that mobile operators need to begin planning on capex for 900 MHz refarming during this timeframe.”
