Huawei started early LTE research more than five years ago. By 2008, Huawei had successfully concluded numerous LTE field tests and trials with China Mobile, SoftBank ,Vodafone and other worlds leading operators. In 2008, with the introduction of our unified BTS platform for LTE, GSM, UMTS, CDMA and TD-SCDMA, we were the first vendor to demonstrate dual UMTS/ LTE, dual CDMA/LTE, and dual TD/LTE mode capabilities. Huaweis multiband and multimode solution now effectively assure operators an ultimately smooth and cost-efficient upgrade from a 2G/3G to a LTE network. In
December of last year, Huaweis efforts were rewarded with the world's first LTE commercial contract, which clearly evidences the dominant position and strength of Huaweis LTE system. In the second quarter of 2009, Huawei will be among the first wave of vendors to introduce LTE commercial solutions and products. In 2010, Huawei will release a second round of LTE commercial solutions and products. Also in 2010, TeliaSonera will launch their commercial LTE network based on Huaweis technology.

To address the accelerating needs of LTE, we have developed several advanced radio technologies, such as adaptive MIMO, Soft Frequency Reuse and Advanced Receiver-IRC. These key technologies serve to increase radio link reliability, cell capacity and overall coverage of LTE. To ensure the fastest maturity, Huaweis LTE has been developed based on our existing mature Unified BTS platform. Subsequently, the immediately available LTE solution can result in an All-IP, high speed, low latency and high frequency efficiency mobile network where
LTE technology supports a much higher data rate than conventional 3G/UMTS. Field trials have evidenced Huaweis LTE DL peak data rate at 173 Mb/s with a handover success rate exceeding 99%. In mobility testing, the highest speed exceeded 350 km/h. Another first was achieved with Huaweis mastery of high efficiency PA and its application to RF design. Correspondingly, we are now able to reduce e-NodeB power consumption by as much as 23% with an equivalent reduction in OPEX for operators.

Protecting original operator investments and reducing CAPEX, our complete portfolio of end-to-end LTE/SAE solutions, including terminals, OAM, e-NodeBs, ePCs, transport, Rich e-NodeBs and ePCs, can be flexibly deployed to allow smooth upgrade from 2G/3G. Huawei e-NodeBs support multiband and multimode. Multiband includes both 700 Mhz and 900 Mhz frequencies, AWS to 2.6G and Bandwidth from 1.4 Mhz and 3Mhz to 20 Mhz. Huawei is equally committed to the development of
multimode base stations to permit the adoption of multiple air interfaces including UMTS, CDMA, GSM, TDSCDMA and LTE. The internal interfaces, functionality and manufacturing are all unified for module sharing, thus ensuring future migration and upgrade. The compact size and structure of the unified footprint brings operators the added bonuses of easy site acquisition, lowered site installation costs, reduced energy demand and unified maintenance.

Huaweis SAE solution has three highlights: Simplicity, Openness and Intelligence. Simplicity is the most important requirement for the future network architecture. Huawei is dedicating considerable resources to advancing development of All-IP Flat Networks, Unified Platforms, Multi-Access, SGSN/MME Pool, GGSN/UGW Pool, and SON networks. Huaweis Unified Platform can merge SGSN, AG and MME into one Unified Serving Node, and merge GGSN, PDSN, ASN-GW, PDG, Serving-GW and PDN-GW into one Unified Gateway node. Multi-access provides accesses to 3GPP, 3GPP2, and non-3GPP at the same time. With all these features, Huaweis simplified SAE network will be both reliable and self-adjusting, with decreasing numbers of nodes and equivalent reductions in CAPEX/OPEX, making overall Operation & Maintenance easier and more efficient. Openness, The Huawei SAE solution is an open architecture that is fully compliant with 3GPP standards and flexible and scalable deployment for third parties. Designed by distributed architecture, with the centralized policy server and signature DB deployed, the UGW is ultimately flexible when it comes to resource allocation. Intelligence, Huaweis SAE solution is also based on Intelligent Packet Network. UGW is embedded with dedicated, powerful hardware DPI, and becomes a service awareness node. UGW can also work with a centralized

policy server, PCRF, providing rich and flexible content control, including flow-based charging, online charging, P2P bandwidth control, policy control, and service reporting. Huaweis in-depth knowledge of Radio Network Planning & Optimization has also allowed for development of the GENEX
Series, delivering advanced network planning and optimization. Based on the SON concept, and in response to operator insistence on mobile OSS network integration, we have applied extensive R&D investment to the perfection of unified EMS for 2G/3G/LTE and web-based LMT.

Huawei is devoted to driving the inter-vendor IODT/ IOT and industry process. In 2007, Huawei joined LSTI and is now a member of the LSTI Steering Board. Huawei expects to increase trial support of LSTI and actively increase open cooperation with terminal vendors and chipset manufacturers. Between Q107 and Q308, to help us develop and issue mature and stable LTE commercial solutions, we entered into ongoing cooperative agreements with key operators and completed exhaustive LTE field trials.

users, and eventually supporting up to 450-km/h high-speed mobile users in the near future High maturity The DBS3900 LTE inherits the mature experience in product design and development of Huaweis 4th generation distributed base stations. Large capacity and wide usability One DBS3900 LTE BBU used for LTE supports up to six carriers, a maximum of 3000 users per e-NodeB. The physical throughput of the LTE is up to 173 Mb/s in a downlink with 22 MIMO, 64QAM, 20 MHz and 84 Mb/s in an uplink with 12 SIMO, 64QAM, 20 MHz per cell. Co-Site of 2G and 3G Networks and Smooth Evolution Hardware components, such as power, RF feeders, and transmission ports, can be shared among the DBS3900 LTE and the existing GSM/UMTS/CDMA equipment. Thus,
operators can save on LTE site construction costs and implement smooth network evolution by reusing existing equipment. The DBS3900 also supports mobility management between the LTE and the existing 2G or 3G networks. This enables operators to deploy a complete LTE overlay solution to work in conjunction with the existing 2G or 3G networks. Small size and easy installation The BBU can be installed on a wall, in a standard 19-inch cabinet or rack. The RRU weighs less than 20 kg. Flexible installation location and low space requirements save site lease costs. Flexible Bandwidth Support The DBS3900 LTE supports channel bandwidths of 5, 10,
15, and 20 MHz in the first release. Thus, the DBS3900 LTE helps to meet the needs of different network operators with different bandwidth allocations, and also allows them to use both existing and new frequency spectrums to provide the different services. Application Scenarios Huaweis DBS3900 LTE can be applied to hot spot areas, such as urban, suburban, rural, highway, and indoor coverage. The BBU can be installed in an idle slot in an indoor rack, cabinet, an outdoor power distribution cabinet, a pole or on the tower, the indoor wall, against the indoor wall or behind a shield on the rooftop. (The RRU does not require space in the equipment room.)
