HUAWEI TECHNOLOGIES CO., LTD. Page 11 The Opinion about LTE in the Industry (Research Companies) Nearly 300,000 LTE Base Transceiver Stations will be installed by 2014, according to a study from ABI Research in Jul Network operators will invest a total of almost $18 billion in LTE capital infrastructure over the period to LTE is the edge tool of FMC, and LTE will act as the leader of the mobile communication, keep the competitive ability of UMTS in the next 10 years.

HUAWEI TECHNOLOGIES CO., LTD. Page 12 The Opinion about LTE in the Industry (Operators) Promoter and Steady supporter of LTE AT&T says its next-generation roadmap leads to LTE, though it's evaluating the use of WiMAX technology for backhaul. But they haven’t excluded the possibility of WiMAX technology at this point.— Jun 2007 NTT DoCoMo Announced to start LTE test since Jul 2007, which plan to release commercial network in 2009, and hope LTE can smoothly evolve to 4G in 2011~2012 Most GSM operators believe GSM->WCDMA/HSPA-> LTE is the right choice. But some operators such as Sprint Nextel 、 Clearwire and Sistema (Russia) still hope to deploy WiMAX for the mobile broadband solution

HUAWEI TECHNOLOGIES CO., LTD. Page 13 LTE/SAE Technology Life Cycle LTE (Long Term Evolution), a 3GPP concept, defines a long-term evolution for radio access technology. SAE (System Architecture Evolution), a 3GPP concept, defines a long-term evolution for core network. LTE and SAE have been approached independently, however by enhancing each other, they are no more separable today Initial study completed Standard aimed to be finalized Trial start Commercial deployment start Year Mass deployment Standard aimed to be developed Source: 3GPP &UMTS-Forum
