Therefore, many diversified network applications and services can be applied further for the prevalence of nomadic clients. In this paper, we introduce a new network deployment of WiMAX to effectively provide high-quality video streaming of live news reporting (i.e. LNR) for TV stations in Taiwan, Both services of WiTV (IPTV over WiMAX) and e-SNG (WiMAX News Gathering) are provided for users and reporters respectively in proposed WiMAX deployment. Besides, to effectively provide LNR service, this island-wide WiMAX network deployment with access range of more than 350Km applies not only the relays of digital microwave links with end-to-end distance reaching to 70Km, but also the port-based VLANs to differentiate services to guarantee quality of service for LNR without interference from other irrelevant traffics. On the test-bed of proposed WiMAX deployment, the performance results from experiments on H.264/SD video streaming demonstrate cost-effectiveness and feasibility of LNR for TV stations.","PeriodicalId":192563,"journal":{"name":"2009 IEEE Mobile WiMAX Symposium","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114839554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An international collaboration, led by the Taiwan Industrial Technology Research Institute (ITRI), has been working to implement a dedicated WiMAX network for a user field trial on the Taiwan High Speed Rail (THSR) bullet train system. Continuous wireless coverage at train speeds up to 300km/hr is challenging due to a number of critical issues, including handover at high speeds and coverage in challenging terrain such as tunnels. A Radio-over-Fiber (RoF) Distributed Antenna System (DAS) was developed by Corning Incorporated to address the critical issue of handover and increase the coverage for each WiMAX basestation. For a DAS deployment consisting of multiple discrete antennas, proper signal strength management is required because the maximum delay spread allowed by the WiMAX protocol is easily surpassed at realistic fiber ranges up to 9km. This paper reviews some of the initial results of the RoF DAS experiments in SongShan tunnel in Taipei. Error-free signal transmission was achieved when the difference in received power from two consecutive antennas was greater than 10dB.","PeriodicalId":192563,"journal":{"name":"2009 IEEE Mobile WiMAX Symposium","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128078216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recent mobile WiMAX standard (802.16e) supports broadband applications to mobile terminals and laptops in urban environments. Mobile WiMAX supports a full range of multiple-input multiple-output (MIMO) techniques including space time block coding (STBC), spatial multiplexing (SM) and eigen-beamforming (EB). This paper compares the performance of the above schemes in terms of achievable throughput and operating range. Simulated packet error rate (PER) and throughput results are presented for each MIMO technique, and for a range of modulation and coding rates. Based on a typical link-budget, the expected throughput for each scheme is computed as a function of the basestation-terminal separation distance. The paper highlights the use of Adaptive MIMO Switching (AMS) in mobile WiMAX. The SNR switching points between each MIMO mode is determined and their dependency on channel spatial correlation is demonstrated. Finally the operating range of the different MIMO schemes is determined (based on a 10% PER) for a mobile WiMAX system. The use of eigen-beamforming together with AMS is shown to offer significant performance benefits in terms of robustness, capacity and operating range. For the scenario under test, the use of eigen-beamforming (based on the dominant eigen-mode) extends the operating range by 16%, and doubles the received data rate for 65% of locations.","PeriodicalId":192563,"journal":{"name":"2009 IEEE Mobile WiMAX Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130190298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
