在通信网络中,接入技术自始至终都是发展的热点。从时分、频分、码分到目前的空分,
从TDMA、CDMA到OFDMA,从单天线到智能天线,先进的技术日新月异,层出不穷。而随着这些新
技术的涌现,WiMAX网络也逐渐成为下一代通信系统的竞争者。很多人认为WiMAX即使无法最终
取代3G,也将是构建未来4G网络的基础,因此很多国际通信设备厂商对于正在兴起的WiMAX寄予
厚望,北电网络甚至放弃了传统3G的研发而专攻WiMAX。 -In the communications network, access technology throughout the development of hot spots. From midnight, frequency division, code assigned to the current air separation, from TDMA, CDMA to OFDMA, from a single antenna to the smart antennas, advanced technology with each passing day, one after another. With the emergence of these new technologies, WiMAX network is becoming the next generation of communication systems competitors. Many people think that WiMAX if not eventually replace 3G, will also be building a foundation for future 4G networks, so many international communications equipment manufacturers who are high hopes for the emergence of WiMAX, Nortel Networks or even to abandon the traditional 3G research and development and specializing in WiMAX.
