  2. Digital enhanced cordless telecommunications ( dect ) is a general radio access technology standardized by the european telecommunication standards institute ( etsi ), which is for short range wireless communications, so that it can be interfaced to a large number of local and public networks such as internet, pstn, x. 25, etc. dect can be interfaced to the internet to provide seamless access

    數字增強型無繩通訊（ dect ）是一種通用無線接入技術，其規范由歐洲電信標準化組織etsi制定，用於短距無繩通信。 dect系統可接入許多本地及公共網，如： internet ， pstn ， x . 25等。
  3. After deregulation of the fixed telecommunication network service ( ftns ) market in july 1995, the three new ftns operators - hutchison communications limited, new t & t hong kong limited and new world telephone limited - have begun to roll out their networks and gradually introduce new services such as integrated services digital network services to compete with the dominant operator, the hong kong telephone company limited ( hktc )

    隨著固定電訊網路（簡稱"固網" ）服務市場於一九九五年七月開放， 3家新固網公司和記廣訊有限公司、香港新電訊有限公司和新世界電話有限公司已開始展開網路和逐步引進各種新服務，例如綜合服務數據網路，與在市場佔有優勢的香港電話有限公司（簡稱"香港電話公司" ）競爭。
  4. Due to a variety of its advantages such as high bandwidth efficiency and robustness against multi - path delay, it has been widely used in the fields of digital audio broadcasting, digital television and wireless local area networks and is likely to become one of key technologies of fourth generation mobile communications

    由於具有很高的頻譜利用率，很強的抗多徑延遲能力，它已經廣泛的應用在數字音頻廣播、數字電視以及無線局域網當中，並有望成為第四代移動通信的關鍵技術之一。
  5. On the other hand, recent advances in communication and modulation methodologice, as well as in adaptive digital signal processing and error detection and correction, have opened the way for the development of effective medium access control and physical layer protocols that support power line communications ( plc ) networks operating at speeds comparable to those obtained from specially wired and more recent wireless local area network in mid - 2001, an industrial standards organization called the homeplug powerline alliance, originally founded by 13 companies including cisco, motorola, intel, panasonic, and texas instruments, announced the completion of the homeplugl. o specification for a l. 0mb / s class in - home power line networking technology based on orthogonal frequency - division multiplexing ( ofdm )

    但是，近年來通信和調制技術的發展，特別是自適應數字信號處理和錯誤檢測及糾正技術，使電力線通信技術出現新的mac層和物理層協議，其性能可以和一些專用有線網路以及最近十年流行的無線局域網技術想媲美。在2001年，一個由13個公司（包括cisco ， motorola ， intel ， panasonic ， andtexasinstruments ）組成的組成的標準組織? ? homeplugpowerline聯盟，頒布了完整的homeplug1 . 0規范，改規范使基於正交頻分復用技術，主要針對10mb s室內電力線網路技術。
