| 中文摘要 | 電信科技的快速發展,使得提供不受時空限制便利的個人通信服務( PCS )日趨 成熟,而無線電話系統為其中重要的一環。第一代無線電話 CT-1 系統主要應用在室內,作 移動通信使用;第二代 CT-2 無線電話系統演進至可用在室內及室外作無線公用電話使用; 第三代 CT-3 無線電話系統主要作無線專用交換機( Wireless PABX )之應用, 提供移動 及交換機之功能,為 DECT 系統之過渡型產品。 DECT 系統除結合上述三種系統之應用外, 亦增加了無線用戶迴路( RLL )之應用, 其高容量之系統設計、 ISDN 相容與 GSM/DECT interworking 等特性,使得 DECT 系統應用層面提升,深具市場發展之潛力。 本文將簡介 DECT 系統及在電信研究所所區試用之結果。 |
| 英文摘要 | The fast progress of telecommunications technologies promotes the personal communications services to be gradually mature. However, cordless phone will play the most important role. The first generation cordless phone CT-1 is mainly applied at indoor environment for user mobility, the second generation cordless phone CT-2 is evolved to be used indoors and outdoors as a telepoint in public, and the third generation cordless phone CT-3 is improved as a wireless PASX, which provides user mobility and radio exchange functions and is regarded as an interim product of DECT (Digital European Cordless Telecommunications) system. DECT system can provide not only the aforesaid cordless phone functions but also the RLL (Radio in the Local Loop) applications. Besides, DECT system has many features such as being compatible with ISDN (Integrated Service Digital Network), capability of handling high traffic demand and interworking with GSM cellular system. These advantages make DECT system more applicable and potential in market competition. In this article, we will briefly introduce DECT system and show the trial result for DECT system in TL. |
