第三代移動通信系統(tǒng)（也稱3G）是移動通信市場經(jīng)歷了第一代模擬技術(shù)的移動通信業(yè)務(wù)的引入，在第二代數(shù)字移動通信市場的蓬勃發(fā)展中被引入日程的。在當(dāng)今Internet數(shù)據(jù)業(yè)務(wù)不斷升溫中，在固定接入速率（HDSL、ADSL、VDSL）不斷提升的背景下，第三代移動通信系統(tǒng)也看到了市場的曙光，益發(fā)為電信運營商、通信設(shè)備制造商和普通用戶所關(guān)注。
移動通信技術(shù)開始是各自發(fā)展的狀態(tài)，各個國家、技術(shù)組織都不斷發(fā)展自己的技術(shù)，美國有AMPS、D-AMPS、IS-136、IS-95，日本有PHS、PDC，歐洲則是GSM。這種格局一方面在移動通信發(fā)展的初期滿足了用戶的需求，開拓了移動通信市場，另一方面也人為造成地區(qū)間的隔離，引發(fā)了全球統(tǒng)一移動通信制式的需求。ITU正是在這個背景下于1985年啟動了第三代移動通信系統(tǒng)的規(guī)范工作。
在第三代移動通信規(guī)范提案的概念評估過程中，寬帶碼分多址（WCDMA）技術(shù)以其自身的技術(shù)優(yōu)勢成為3G的主流技術(shù)之一。這里主要介紹WCDMA起源、面臨的移動通信市場和業(yè)務(wù)狀況、WCDMA技術(shù)特點、發(fā)展現(xiàn)狀和演進方向 ......
The 3rd Generation Mobile Communication System (also known as 3G) mobile communications market has been affected by the first generation simulation technology of the mobile communication business introduction of the second generation digital mobile communications market boom has been put into the development agenda. In today's Internet data services continues to heat up, fixed access rate (HDSL, ADSL, VDSL) rising background, the third generation mobile communications system, the market saw the light. pickings for telecommunications operators, telecommunication equipment manufacturers and users of general concern. Mobile communication technologies is the development of their own state, every country and technical organizations have developed their own technology, American AMPS, GSM, IS-136, IS-95, Japan's PHS, PDC, Europe is GSM. While this pattern in the development of mobile communications initial meeting user demand and develop the mobile communications market, the other man-made regional isolation, sparking a global unified standard mobile communications needs. ITU It is in this context to the 1985 launch of the third generation mobile communication system to regulate the work. In the third generation mobile communications regulatory concept of the proposal evaluation process. Wideband Code Division Multiple Access (WCDMA) technology in their own 3G technology to become one of the mainstream technology. Here introduces WCDMA origin, the mobile communications market and business conditions, technical features WCDMA, Development status and direction of evolution.
WCDMA is the major incentive to the commercialized 3G services. Elaborately, in 2005, more than forty commercial WCDMA networks were released worldwide; accounting for about 80% or more of all 2005 released 3G networks. By December 2005, there had been 100 WCDMA networks released in 42 countries all over the world, which illustrates over two-thirds of WCDMA license holders have already released their own 3G business operations. Furthermore, it also reflects the maturity of this te Analysis of WCDMA network development ......
