中文摘要 | 在行動寬頻系統(Mobile Broadband System, MBS)的發展上,無線通信和寬頻網 路接取的需求愈來愈顯得迫切。目前為止,第三代行動通信IMT-2000標準將可提供2Mbps 的頻寬以因應語音、數據與影像傳遞之需要。然而2Mbps的頻寬對於各種寬頻多媒體服務仍 有不足之慮。因此,將無線通信與ATM技術整合的第四代寬頻無線通信系統的研發與試驗在 世界各地一直不斷地進行中,其中無線非同步傳送模式(Wireless Asynchronous Transfer Mode,WATM)是一項關鍵的技術。在這篇文章中,我們將探討目前WATM標準訂定及技術發展現 況,並將對末來行動寬頻系統預期之演進過程做深入的討論。 |
英文摘要 | The need for wireless communication and broadband Internet access has become more and more urgent recently. In the third generation mobile communication standard, IMT-2000 will provide the bandwidth of 2Mbps to satisfy the necessity of voice, data and video services. However, the bandwidth of 2Mbps is not enough for the future broadband multimedia service. Because of the above reasons, the integration of wireless communication and ATM technology is in progress in the worldwide. Wireless Asynchronous Transfer Mode (WATM) is one of the key technologies for pushing our life into the Mobile Broadband System (MBS) world. In this paper, we will not only focus on the development of current WATM standards, but also introduce a number of WATM trial systems. Finally, we proposed an evolution blueprint of MBS which can help to build the wireless communication infrastructure in the near future. |
