The Race to Evolve 

Around the world, at every level of personal and business life, wireless has become firmly established as a ubiquitous facet of daily communication. For many, to be without a mobile device would be as unthinkable as going without clothes. Reliance on wireless increases daily. Seemingly unaffected by fluctuations in the economy, in a search for work the unemployed need mobile broadband every bit as much as the employed, These dictates are not based on lifestyle alone. From business to government and from education to health, users automatically expect all the established standards, services and products of fixed broadband, satellite and wireless to seamlessly and invisibly migrate overnight to mobile. Mobile broadband and IP wireless linking are waves of the future that are with us today. For operator success on every continent, meeting expectation is no longer optional, it has become essential. 

Despite users' implicit belief that science fiction is now fact, many challenges remain for both operators and vendors. In terms of responding to subscribers' anticipations while resolving deployment and cost issues, we have first to address the existing limitations of GPRS, EDGE, WCDMA, HSPA/TD-SCDMA, and CDMA/EV-DO where legacy networks typically encounter bottlenecks when attempting delivery of high quality mobile broadband services. Expelling the bottlenecks, LTE bursts ahead with over spontaneously responsive speeds of 100Mbps downlink in the 20MHz bandwidth and 50Mbps uplink .Reduced latency and increased cell edge performance makes LTE driven service even more attractive.
Based on LTE enablement, operators can attract users by providing exponential added services. For mobile business users, high efficiency video TV; broadband email; electronic financing; large file/batch switching, and accelerated commercial information browsing expedite business transactions, departmental and customer interaction. For consumers, social communication is enhanced; entertainment resources and access become virtually unlimited; mobile blogging; interactive high quality media; media file downloading and online gaming, all become commonplace. In the LTE era, mobile terminals become workstations, play stations digital video recording, editing and publishing platforms.
LTE will also improve network capacity and competence. 3GPP requirements call for LTE's spectral efficiency to be three- to four-times the Release 6 HSDPA levels in the Downlink (100Mbps), and two to three times the HSUPA levels in the Uplink (50Mbps).. This advance in network capacity makes it possible for the operators to promote wireless broadband services at prices that are in line with market expectations.

Huawei's Roadmap to LTE 

Huawei believes LTE is the key to global introduction of mobile broadband services. In the coming months, we will maintain our existing level of investment across GSM, UMTS, CDMA and TD-SCDMA while dedicating added resources to drive LTE. Our LTE success will be built on the proven abilities of our GSM, UMTS, EV-DO and TD-SCDMA solutions that now see us working with more than 70% of the world's leading operators. 

The First in the Industry

In 2008, with application of our unified BTS platform for LTE and GSM, UMTS. CDMA. TD-SCDMA, we were the first vendor to demonstrate dual UMTS/LTE, dual CDMA/LTE, and dual TD/LTE mode capabilities. Huawei's multi-band and multi-model solution now effectively assures operators an ultimately smooth and cost-efficient upgrade from a 2G/3G to a LTE network. 

Huawei's in-depth knowledge of Radio Network Planning & Optimization, has also allowed us to develop 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' OSS system currently offers operators powerful functionality, including Unified Management, Self Configuration and Self Optimization. Very conclusively, our evolved OSS system can help operators dramatically simplify the Operation & Maintenance process, improve the efficiency of Network Management and, in the process, considerably reduce any operator's TCO and while realizing long-term investment protection.

Excellent Performance

To address the 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, Huawei's LTE e-NodeB 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. 

Another first was achieved with Huawei's 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 40% with an equivalent reduction in OPEX for operators. Huawei was also the industry's first to realize the essential features of SON -- such as ANR(Automatic neighbor relation), MRO(Mobility Robust Optimization), Alarm Correlation Reporting, and Network Health Checking.

Full Package

Protecting original operator investments and reducing added CAPX, our complete portfolio of an end-to-end LTE/SAE solution, Rich e-NodeBs and ePCs can be flexibly deployed to allow smooth upgrade from 2G/3G. Huawei e-NodeBs support multi-band and multi-model, multi-band includes 700M, 900M, 1800M, 1900M, 2100M, 2600M and AWS. 

Several hundred systems engineers expedited development of Huawei's multi-mode base station to permit the adoption of multiple air interfaces including UMTS, CDMA, GSM ,TD-SCDMA and LTE. The internal interfaces, functionality and manufacturing are all unified to share the modules, 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.


Win-Win Partnership

Leading from the Start: In 2004, Huawei declared pioneering support for LTE by initiating LTE Study Item in 3GPP and supported the commitment with an immediate and intensive investment in LTE research. Our industry dedication now extends 3GPP, to NGMN and LSTI. Representing our advancement of LTE standards, as of Q108, by the end of Dec.2008, Huawei had submitted more than 1,450+ contributions.

Proven Trials on Three Continents: 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 in Europe, North America, Japan and China -- all of which yielded exemplary test results. The physical throughput of LTE was up to 172.8Mbps in downlink with 2*2 MIMO and 84Mbps in uplink with 1*2 MIMO per cell (20MHz, FDD system).

Huawei's commitment to and investment in LTE now provides operators worldwide with a win-win situation where advanced technology enables optimal long-term service, optimal user experience, added revenue streams and more – all with considerable reduction in TCO,CAPEX, and OPEX.

The World's First Commercial Application

In Q109, Huawei was chosen by the largest telecoms operator in Scandinavia and the Baltic countries, to supply the world's first commercial 4G/LTE network, in Oslo, Norway. Together with our customer, Huawei will raise mobile broadband speeds significantly by dramatically improving quality and capacity with our advanced LTE solution.

Under the agreement, we will deliver an environmentally friendly end-to-end LTE solution to cover the capital city of Oslo -- including LTE base stations, core network and OSS (Operating Support System). We will also provide services including network design, implementation, systems integration and support.

Employing Huawei's 4th Generation Base Station platform, our LTE solution will result in an all-IP, high speed, low latency and high frequency efficiency mobile network. LTE technology will deliver new mobile data rates, which will enable the operator to introduce the fastest mobile broadband experience to their customers and quickly evolve to the next generation network.

Confirming their selection of Huawei, the operator's CTO stated, "We have chosen Huawei as our partner based on their strong focus on LTE development and early deployment capabilities, as well as Huawei's impressive and proven worldwide track record in advanced mobile technology." 

In similar fashion throughout 2010, Huawei intends to remain ahead of the industry curve by providing leading-edge LTE commercial solutions to allow operators around the world to establish and maintain long-term competitive LTE leadership.
