The possible remedy for the situation may need to adopt the broadband wireless access technology with licensed-exempt spectrum. This study analyzes the broadband wireless access industry and proposing the applicable business model and strategy for equipment vendors. After the analysis we found Wi-Mesh technology at the current stage is the best fit for BWA industry, for the long run this study will provide the future development direction and study areas for BWA vendors.Table of Contents Acknowledgements 三 論文摘要 四 Abstract 五 Table of Contents 六 Table of Tables 九 Table of Figures 十 List of Acronyms 十二 Chapter 1 Introduction 1 1.1 Research Motivation 1 1.2 Research Objective 5 1.3 Research methodology 6 1.4 Thesis’ structure 8 Chapter 2 Wireless Industry Evolution Overview 10 2.1 First Generation (1G): AMPS Basic Mobile Voice 11 2.2 Second Generation (2G): TDMA, CDMA, GSM Quest for Capacity and Coverage 13 2.3 Second Generation (2.5G): GPRS Basic Mobile Data Service 14 2.4 Third Generation (3G): WCDMA, UMTS, 1xRTT Quest for Data with Higher Speeds 15 2.5 Beyond Third Generations (B3G):1xEVDO, HSDPA Quest for Broadband Wireless Multimedia Services 17 2.6 Future Generation (4G): UTRAN LTE, WiMAX, Wi-Mesh Ubiquitous BWA Service 19 2.7 Summary 20 Chapter 3 Broadband Wireless Access Industry Analysis 24 3.1 Wireless Fidelity (Wi-Fi) – Hotspot Coverage 24 3.2 Wireless Mesh Networks (WiMesh) – Hot-Zone Metro-wide Seamless Coverage 25 3.3 Worldwide Interoperability for Microwave Access (WiMAX) – Rural and Urban Coverage 29 3.4 BWA Landscape Overlook 34 3.5 Spectrum Allocation 37 Chapter 4 Wi-Mesh Market Analysis 42 4.1 Technology Evolution 43 4.1.1 First Generation – Single Radio Mesh 44 4.1.2 Second Generation – Multi Radio Mesh Systems 46 4.1.3 Third Generation – Modular Radio Wi-Mesh Systems 47 4.1.4 Fourth Generation – WiMAX + Wi-Mesh Systems 49 4.2 Key Market Drivers 49 4.3 Key Market Participants 52 Chapter 5 Business Model Strategy 56 5.1 Business Models 57 5.2 Industry Factors 58 5.2.1 Competitive Forces 59 - Rivals 59 - New Entrants 65 - Substitutes 65 5.2.2 Cooperative Forces 66 - Suppliers 66 - Micro-Complementors 67 - Macro-Complementors 67 - Customers 69 5.2.3 Macro environment 69 5.3 Firm-Specific Factors 71 5.3.1 Positions 71 - Customer Value: 71 - Market Segments 72 - Sources of Revenues 75 - Price 75 5.3.2 Activities 77 5.3.3 Resources 79 5.3.4 Costs 79 5.4 Profitability 80 5.5 Market Analysis of Broadband Wireless Network 80 5.6 Customer Business Model 81 Chapter 6 Summary and Conclusions 85 Appendix A 90 Reference 924079447 bytesapplication/pdfen-US寬頻無線接取營運模式無線網際網無線都會型網路Broadband Wireless AccessBWAPublic WLANBusiness ModelsWi-MeshWireless Mesh Networksotherhttp://ntur.lib.ntu.edu.tw/bitstream/246246/54391/1/ntu-95-P93747017-1.pdf
