一项由我国科学家自主研发的第三代移动通信系统技术———ＬＡＳ -ＣＤＭＡ(大区域同步码分多址接入技术 ) ,日前在 1.6Ｍ的带宽上实现了上行 6 4ｋｂｐｓ、下行 384ｋｂｐｓ的数据传输速度 ,不仅领先于其它第三代移动通信技术 ,而且在性能上完全满足并大大超过国际电联规定的
A third-generation mobile communication system technology developed by our country scientists --- LAS-CDMA (Large Area Synchronous Code Division Multiple Access technology), has recently realized an uplink of 6 4 kbps and a downlink of 384 kbps at a bandwidth of 1.6 M Data transfer speeds, not only ahead of other third generation mobile communication technologies, but also fully meet and exceed the performance of the ITU
