由英特尔等IT厂商主导的WiMAX技术因为高带宽、低成本、多类型终端、系统开放等优越特性,一度受到大力追棒,并在2007年被批准为3G标准,目前已在全球超过118个国家得到商用部署。2008年开始,WiMAX产业链开始遭遇一系列打击,从2009世界移动通信大会上也可以看出,在近几年各类通信大会上占尽风头的WiMAX宣传势头大大减弱。而且,随着WiMAX商用网络的快速部署,组网过程中存在的问题逐渐显现,影响了其在全球的进一步发展。虽然WiMAX似乎正在淡出业界视野,但由于WiMAX与全球通信界共同的演进路线LTE在MIMO和OFDM等关键技术方面存在一致性,其组网过程面临的一些问题LTE必然也将遭遇。而LTE是我国三大运营商共同的演进目标,在我国乃至全球的研究正如火如荼。因此,我们试以WiMAX的组网问题为引子,开放式地进行探讨,以期对LTE的组网研究提供有益借鉴。
WiMAX technology dominated by IT vendors such as Intel was strongly chased after its superiority due to its high bandwidth, low cost, multi-type terminals and open system. It was approved as a 3G standard in 2007 and is now in more than 118 countries around the world Get a commercial deployment. Starting from 2008, the WiMAX industry chain started to suffer a series of strikes. As can also be seen from the 2009 World Mobile Congress, the tendency of WiMAX promotion, which is preoccupied with various communications conferences in recent years, has greatly weakened. Moreover, with the rapid deployment of WiMAX commercial networks, problems in the networking process gradually appear, which affects their further development in the world. Although WiMAX seems to be fading out of the industry’s perspective, due to WiMAX and the global telecommunications community evolution route LTE in the MIMO and OFDM and other key technologies there is consistency, some of the problems facing the networking process LTE will inevitably encounter. LTE is the common evolution goal of the three major operators in China. Research in China and even in the world is in full swing. Therefore, we try to open up the problem of WiMAX networking as an introduction, in order to provide a useful reference for the study of LTE networking.
