Press ClippingIndia and China Marketscan Complement Each OtherJune 15, 2007, ElectronicsForYouZTE is the fasted growing telecommunications equipment suppliers in the world.In 2005, its global sales revenue reached approximately $2.8 billion withover 27,000 employees worldwide. The next year the company’s India revenuehovered around $500 million and now it hopes to cash on the merging trend ofcontract manufacturing in India. Prasoon Srivastava of Electronics Bazaar, in aninteraction with Liu Ren, director, marketing, ZTE India and Ding Kun, director,R&D Center finds out more about the company’s India plans and discusses therecent trends of Chinese companies showing investment interest in India.In recent times we findgovernments of both India andChina encouraging bilateral tradeactivities. What is your opinionabout such initiatives?The political and business relationsbetween India and China have certainlyimproved qualitatively. Immediatelyafter the MOU was signed betweenASSOCHAM and the visiting Mayorof Shenzhen last year, the former set upand office in Shenzhen and Indo-Chinabusiness ties were formed. This wasa quantum leap. We strongly believethat India and China will be poweringthe world economy in the comingfuture. ZTE is also optimistic about thegrowth of Indian telecommunicationsindustry and feels honored to be a partof it.When did you start marketing yourproducts in India? How has beenyour experience in the country tilldate?ZTE operations in India commencedway back in 2001-02–almost six yearsago. Initially we used to market ourproducts through our partners. Butsince the last few years, our productsare being sold directly to the serviceproviders through local offices. In lastfinancial year ZTE India garnered arevenue of $500 million.How would you compare the Indianmarket vis-à-vis China? How doplayers from both the countriesbenefit from each other’ strength,mitigating the weakness?W h i l e t h e r e a r e l o t m a n ydifferences, the two markets are similarin many ways. Both the nations have ahuge technical and skilled manpowerbase, both are economically dependenton agriculture. The differencesactually lies in the state of economicdevelopment. China is miles aheadZTE TECHNOLOGIES 5

Press Clippingof India, as far as development isconcerned. However, India is rapidlycatching up, so much so that, theChinese companies are expecting alarge share of their revenues to flow infrom India.Everything said and done, there isno denying the fact that the Indian andChinese markets are complementaryto each other. While China boasts of astrong manufacturing base, softwaredevelopment and IT skills happen tobe India’s forte. These are the areaswhere the countries can synergizetheir strengths and complement eachother. India will be offering softwareand applications IT hardware will besupplied by China.The Indian SemiconductorAssociation in conjunction withFrost and Sullivan, predicted thatelectronics equipment productionin India would grow up to $363billion by 2015. Your take on this…This is quite feasible. Leaveaside the ever-inflating demand forelectronics consumer durables. Lookat it from the telecommunicationsperspective alone. The government iskeen on providing 650 million phonesby 2012 (from the current level of200 million). Coupled with this is thetarget of touching the 30 million markin broadband during the same period(from the current level of one million).All these will eventually result ina tremendous creation of basic andvalue-added infrastructure, therebyspurting production of electronicsequipment like semiconductors, PCBs,etc. So, production worth $363 billionby 2015 is not that impossible a dreameither!If this be the case then what is itthat keeps Chinese investors awayfrom India?T h e p r o b l e m l i e s w i t hinfrastructure–road, rail, air, power,visa, etc. Add to this the menace ofbureaucratic red-tapism and couchedpolitical statements with veiledmessages on threat to internal security.From our interaction with someIndian and Chinese associationswe came to know that yourcompany is planning to go forcontract manufacturing in India.Tell us your plan on the same.ZTE India is very optimisticabout its prospects in the Indiansoil and our growth plans weremarked by the creation of a lowcostmanufacturing set up. Till theplan matured, we were thinking ofgoing for contract manufacturing tomeet the requirements of some of thegovernment tenders. But now we havea full-fledged manufacturing facility inManesar.What is your take on theSemiconductor Policy recentlyintroduced by the Governmentof India? How are things on themanufacturing unit front?It is definitely a welcome step. Thispolicy, we believe, would be in syncwith the government’s initiatives topromote telecommunications and ITover the next five to ten years.The Indian unit is in its infancyas compared to our other plantslocated worldwide. They are muchbigger both in terms of size andproduction capacity. But the Indiantelecommunications sector offers themost potential market for businessgrowth. As the business expands, sowill the plant size and its capacity.What made ZTE set up both itsresearch and development (R&D)center and manufacturing plant inIndia?India has been doing tremendouslywell since the last seven years. ZTEsees it as the most lucrative marketoutside China.The Indian telecommunicationsi n d u s t r y p r o m i s e s t h e k i n d o fopportunity that no other industryin the world can offer. Keeping thisin mind, we are intending to set upanother manufacturing unit in the nearfuture. A manufacturing plant will notonly enable us to meet the customerdemands on time, but also help us offerbetter customer service.What have been the technicalachievements of ZTE R&D center inIndia since inception? How has ithelped ZTE clients?With about 40 per cent of the workforce dedicated to R&D and with 10per cent of annual revenues channeledto this field. ZTE has 14 wholly ownedR&D centers and institutes acrossNorth America, Europe and Asia.International standards such as CMMand CMMI are strictly applied to ourR&D management processes in Indiaas well as abroad.6ZTE TECHNOLOGIES

In 2000, ZTE launched the world’s firstCDMA mobile phone with detachableSIM card. This was followed by thelaunched of the world’s first CDMAbaseddigital trunking technology–Global open Trunking architecture(GoTa) in 2004. This included manytechnologies based on ZTE-ownedintellectual property.For our customers we have adedicated customer support engineeringand R&D center together with a trainingcenter in Bangalore. The idea behindthis training center is to provide a richexperience in project implementationalong with end-to-end customersolutions. We also have a strong supportfor our India R&D and training centersfrom our headquarters in China.What are the projects that ZTE R&Dis currently working on? Are theyclient specific or industry specific?We are currently concentratingon the Indian telecommunicationsindustry. Right now, the focus is onvalue-added services (VAS), as it isthe most important part of businessfor ZTE. For this, we have introducedAnyservice, which is the brand forour VAS business. This service has alot of applications for all the majorservice providers in India. Currently,four of our R&D centers are workingon Anyservice development with 2000dedicated R&D staff.Anyservice—what is it all about?What are its key features?Z T E ’s A ny s e r v i c e i s a o n e -stop solution for VAS, includingapplications, service control, networkaccess and terminals. Besides usingproprietary software and hardware,it can provide a full range of VAS tosupport the operator’s business needs.The solution can be used in legacyand future network infrastructures.This well-designed and easy-to-useservice greatly reduces operationalexpenditures.Which ZTE projects developed inIndia have won accolades from themarket?See, we are relatively new to theIndian market with just six yearsof presence. Within this short spanof time we have bagged some ofthe major contracts here besidesbecoming the most favored suppliersto almost all the big operators. Wehave also received high appreciationfrom the Indian market for our qualitydeliverables in terms of variousproducts and services.The sales of our infrastructureproducts range between CDMA, GSM,optical transmission, data networks,s o f t s w t i c h , Wi M A X a n d VA S .Terminals products include handsets,data card and IFWT, which in itself isa great accolade for ZTE in the Indianmarket.Not only this, with the developmentof an efficient after-sales team, ourcompany has gathered abundantexperience in after-sales infrastructurem a i n t e n a n c e .

Case StudyThe commercial launch ceremony of ZTE GoTa network. Theceremony held on January 9, 2007 in Kuala Lumpur was attendedby Dato’ Seri Dr. Lim Keng Yaik, Minister of Energy, Water &Communications of Malaysia, and Mr. Yin Yimin, President of ZTEZTE Provides GoTaSystem to MalaysianOperator ElectcomsLiu ShouwenOverview of Malaysia’s TrunkingMarketElectcoms, Malaysia’s leadingtrunking radio and radio-pagingoperator, has 400 MHz MPT and 800MHz analogue trunking systems.These trunking systems principallycover the key areas of the economicallydeveloped West Malaysia with acapacity of over 80,000 trunkingsubscribers and about 10,000 pagingsubscribers.Electcoms is one of the twooperators that have been licensed tooperate a national trunking network.The company has played a crucialrole in the field of radio trunkingcommunications since it enteredthe Malaysian analogue trunkingcommunications market in 1989.However, after years of operation,Electcoms found itself in a difficultsituation: on the one hand, the pagingbusiness was declining, and on theother hand, the existing analogueradio trunking systems have limitedexpandability and need to find newtechnologies to replace them.The signing ceremony of “China-Malaysia EconomicCooperation Projects” on December 15, 2005Electcoms’ GoTa Network PlanElectcoms began to track the digitaltrunking technology and solutions in1999. The company reviewed a widerange of vendors for the current projectand selected ZTE’s CDMA-basedGlobal open Trunking architecture(GoTa) as a strategic technology forthe future development of its trunkingnetworks based on the system’sfeature-rich services and advanceddigital technologies.In December 2005, when ChinesePremier, Wen Jiabao, visited Malaysia,ZTE signed a commercial contractw i t h E l e c t c o m s a t t h e s i g n i n gc e r e m o ny o f “ C h i n a - M a l a y s i aEconomic Cooperation Projects”,which marked the start of a long-termstrategic cooperation between ZTE andElectcoms.The Electcoms GoTa networkwas built in three phases. Phase 1 ofthe network covers West Malaysia,including Kuala Lumpur, and isexpected to reach a subscriber baseof about 50,000 in two to three years;8ZTE TECHNOLOGIES

Phase 2 and Phase 3 will expand thePhase 1 system to cover the whole ofMalaysia.In the initial stage of networkdevelopment, Electcoms will utilizethe differentiated capabilities of thenewly built GoTa system to developnew customer groups. The Malaysiangovernment required the analogue-todigitalconversion of all the trunkingnetworks to be completed by the endof 2008; Electcoms planned to migrateall the existing analogue trunkingsubscribers to the GoTa network.On January 9, 2007, Electcoms helda press conference in Kuala Lumpurannouncing the commercial use of thenetwork based on ZTE’s GoTa. This isthe large-scale commercialization ofthe Chinese-developed digital trunkingsystem in the overseas market.Reasons for Choosing GoTaEquipment pricingIn order to adapt to competition,Electcoms started to trace the digitaltrunking technologies and solutions asearly as 1999.Electcoms has considered theIntegrated Digital Enhanced Network(iDEN) technology and made contactswith Motorola, which then budgetedthe costs of deploying an iDEN systemin West Malaysia for Electcoms.However, Electcoms thought thenetwork-side equipment were fartoo expensive, and that it would beimpossible for them to control thefuture network construction andoperating costs. In fact, Electcomsknew well the Asia-Pacific’s trunkingcommunications market: the iDENnetworks of trunking operators in thePhilippines, Indonesia and Singaporewere running at little or no profit, oreven at a loss; two iDEN operators inSingapore have merged for survival,but their situation has not improvedyet.Network coverageElectcoms has been invited to visitSprint Nextel’s iDEN commercialnetwork in the U.S. Through fieldtesting, Electcoms felt the networktest results, especially the coverageresults, failed to meet its expectation.However, the GoTa digital trunkingsystem has significant greater coveragecapability than iDEN, winning highfavor from Electcoms.SecurityElectcoms has 30,000 legitimatetrunking subscribers on its existing800 MHz analogue trunking network,but the fraudulent subscribers reached20,000. Electcoms often has todedicate manpower to detect andprevent subscriber number cloning.On the contrast, GoTa gives enhancedauthentication and privacy.Professional trunking and richvalue-added servicesElectcoms, as a private enterprise,is very cautious about its futuredevelopment direction. To really knowabout GoTa products, Electcoms’s topofficials came to China to visit ChinaTietong and China Satcom’s GoTacommercial trials, and tested keytechnical indicators such as GoTaservices, coverage, call setup timeand voice quality. With the test resultsfar exceeding their expectation,Electcoms’s management finally madethe decision to adopt GoTa as thetechnology for their future networkdevelopment. Moreover, Electcomswas impressed with the value-addedservices supported by the GoTasystem, such as data services, SMS andLocation Based Service (LBS), and thebasic dispatch control station services.ZTE’s powerful R&D strengthThrough visiting the company,reading major media reports, andespecially by knowing the fact thatZTE is listed on Hong Kong StockExchange, Electcoms believes ZTE isan excellent enterprise with powerfulR&D and management capabilities,with which they can enter into a longtermstrategic partnership.Electcoms’ future developmentplanElectcoms is currently focusingon professional radio trunkingcommunications. Electcoms hopes tocontinually attract customers with itsprofessional trunking services at firstand then utilize the GoTa system’svalue-added data services to explorepotential customers, building a maturetrunking network. GoTa is undoubtedlythe best choice for Electcoms as itemploys 3G wireless technology andadvanced system structure to bringnew space for service developmentof trunking technology, which alsostrengthens Electcoms’ commitmentto GoTa as the future developmenttrend.ZTE TECHNOLOGIES9

Case StudyGoTa Dispatch Solution Serves InformatizationConstruction of China's Tianjin PortFeng ZhihongTianjin Port is located in the lowerreaches of the Haihe River inNorth China Plain. It is the biggestman-made harbor in China and animportant international trade port inNorth China. It serves as the oceangateway to the country’s capital,Beijing, and Tianjin City; it is also oneof the starting points of the Eurasiancontinental bridge in the east. It is66 km away from Tianjin City andover 170 km from Beijing City. Ithas established trade connectionswith more than 400 ports of over 180countries and regions across the world.To meet the requirements of buildinga modernized large port around theBohai Sea Rim region, as well asa super large-scale port in China,Tianjin Port should become a leaderin the construction of an intelligent,informatized port. The powerful radiodispatch and wireless data servicessupported by the GoTa system canmeet the port’s requirements inproduction dispatch, data collection,transmission and processing, as well asresource management, thus realizingthe intelligent dispatch managementfunction.The GoTa services serving TianjinPort have won unanimous praisesfrom port leaders and employees.ZTE provided a series of customizedfunctions and solutions for Tianjin Portthat has features such as high densityworking areas, high intensity work,and coexistence of several types ofwork.Customized Development for theDock ApplicationThrough analyzing the radiodispatch requirements for a TianjinPort container dock, ZTE’s expert teamsummarized the following featuresconcerning the radio trunking dispatchapplications at this dock.● Fixed working area: Trunking usersat the dock work in a certain smallarea, which can be covered by asector or a BTS.● High-density working area: Theworking area has a large number ofusers and can be divided into manytrunking groups.● Frequent trunking dispatches:During working hours, trunkingusers make frequent use of thedispatch function.● Continuity of trunking dispatches:When users use the dispatchservice of the trunking system, thecontinuity of their operations isrequired.● Complicated trunking dispatchprocedure: The radio dispatchoperations at a large port dockinvolve a lot of departments, and theprocess is relatively complicated.12 ZTE TECHNOLOGIES

● High requirements for connectiontime: To ensure the security of dockwork, high requirements have beenplaced on the connection time oftrunking group calls.● Flexible radio dispatch operations:During the specific loading andunloading operations, workers atthe port should be dynamicallyarranged, that is, trunking users canbe grouped as needed.● Practicality and operability oftrunking dispatch operations: Usersrequire flexible and convenientoperations.While taking these features intoconsideration, ZTE’s expert teamhas gained a deep understanding ofthe users’ specific requirements aftercommunicating with relevant staffsof the dock. It divided the workinggroup of the dock into three types–operation, maintenance, and routine–and applied GoTa functions to the site,such as dynamic regrouping, multiplepriorities, dispatch console function,and functional number. At present,the dispatch services at the dock arerunning in an efficient and stablemanner.Customized Development for theContainer Yard ApplicationCompared with the traditionaltrunking radio communicationssystems, GoTa has a powerful datatransmission capability. ZTE, basedon the system’s data transmissioncapability, created a custom datacollection system for the containeryard, targeting the container yardindustry features, such as a largeworking area, widely distributedworkers, f requent informationcollection, and low precision of theexisting system. This system changesthe traditional working mode in thecontainer yard (calling and manualinput) and improves the timeliness andcorrectness of container informationtransmission. In view of users’ specificworking scenario, as well as the ShortMessage Service (SMS) transmissionfunction of the GoTa system, ZTEdeveloped custom SMS-modem anduser interface software, which enablesreal-time input of on-site informationinto the user database via SMS. Thewhole process doesn’t involve anymanual operation, ensuring workefficiency.Unified dispatch management ofLogistics VehiclesThe port is a big arena for logisticsservices. The great variety of logisticsvehicles makes it difficult to uniformlydispatch them. Leveraging thepowerful dispatch, data transmissionand positioning functions of the GoTasystem, the port can implement unifieddispatch of most vehicles.● A unified dispatch platform fortimely command and control: Allvehicles of the port are equippedwith the vehicle-mounted stations.The logistics companies are installedwith the dispatch stations, capableof dispatching and commandingmost of their managed vehicles atany time.● A positioning platform for real-timeinformation about the vehicles: Theinterface of the dispatch console canprovide real-time information aboutthe location and route of the vehiclethat is equipped with GPS vehiclemountedstations.● A complete monitoring of specialvehicles to improve work efficiency:Under the traditional vehiclemanagement mode, it is hard toget information about the concreteand bulk cargo trunks–Tianjin Porthas many such types of vehicles–which may lead to losses anddamages of goods. Supported bythe GoTa system platform, thebackground station can providereal-time information about thestatus of both the vehicles and thecontainers. When any abnormalityoccurs, for example, a driver slacksoff at work or unloads cargo withoutpermission, the background stationwill automatically record it andsend alerts to the driver, protectingthe owner’s benefits and improvingwork efficiency.ConclusionSo far, GoTa has been servingTianjin Port for about two yearswith the user groups distributed invarious departments of the port,covering all frontline productionunits and functional departments. Asthe port informatization constructionis deepening and the port scale isexpanding, the GoTa service platformswill further integrate more applicationslike coalition emergency response,remote metering, electric powermanagement, electronic patrol andmobile office, offering better servicesto Tianjin Port.ZTE TECHNOLOGIES13

Case StudyA Business Analysis ofa GoTa System in Shandong,ChinaWang LeiGlobal open Trunking architecture(GoTa) is the world’s firstCDMA-based next generation trunkingsystem that is independently developedand launched by ZTE.Z T E a n d S h a n d o n g S a t c o m ,a subsidiary of China SatelliteCommunications (China Satcom),jointly built a GoTa trial network inShandong Province, China. The GoTatrial network now has a certain scale,consisting of 68 BTSs, two base stationcontrollers (BSCs), a BSCB, a MobileSwitching System (MSS), a PacketData Switching Subsystem (PDSS),a Dispatch Subsystem (DSS), a ShortMessage Service (SMS) system, a FailCall Notice (FCN) system, a MobileLocation System (MLS) and anIntelligent Network (IN) system.Till now, the network has beenrunning smoothly with an everexpanding commercial subscriber base.It has provided a variety of trunkingservices to Rizhao Port, comprehensivelaw enforcement brigade, logistics,frontier inspection, 120 EmergencyCenter, Jinan Iron and Steel Group, theQingdao Olympic Sailing Regatta, andemergency response for Weifang City.Shandong Satcom’s GoTa networkis capable of delivering integratedcommunications services such asvoice, Push to Talk (PTT), packetdata, SMS, fail call notice, locationbasedservices (LBS), streamingmedia, video monitoring, and etc. Thefollowing strategies have been adoptedto develop the GoTa network:● Accurate market positioning: Thedigital trunking communicationsystem, with special applicationsl i k e e m e rg e n c y d i s p a t c h o rresponse, cannot be operatedin the same way as the existingmobile communication system.Its application mode should givea full play to its trunking features.Shandong Satcom launched theGoTa system under the brand name“Push to Action”, which clarifies thedifference between the dedicatedt r u n k i n g a n d p u b l i c m o b i l ecommunications and highlights theunique service advantages createdby PTT services.● A wealth of services: In addition toprofessional services such as groupcall, private call, floor taken, lateentry and dynamic regrouping, theGoTa system has also developedrich new services to meet the needsof users, including floor queue,on-line user status query, callrestriction, call forwarding, servicepriority and Do not disturb. Withrespect to dispatch console, GoTacan provide new functions like “sendto group” SMS, status display andnumber management, in addition14ZTE TECHNOLOGIES

to the functions of professionaldispatch and management consoles.These rich service functions cansatisfy the demands of industrialusers for basic services, as well asintegrated or combined ones.● Detailed enterprise analysis: Thereare differences in the requirementsof different industries on the digitaltrunking system as they all havedifferent operating procedures.
