cdma2000/CDMA 测试
随着工业需求的成熟和发展,码分多址(CDMA)技术也在成熟和发展。CDMA 是一项基于 TIA/EIA IS-95 CDMA 标准(包括IS-95A 和 IS-95B 两个版本)的数字蜂窝技术,首次面世是作为一款话音通信解决方案。它使用直接序列调制(带数字编码)来扩展其频谱。
随着用户设备和应用软件的发展,CDMA 已为 cdma2000 让路。cdma2000 是由电信工业联盟开发的一种技术,在 1.25 MHz 单一信道中支持电路交换话音通信以及高达 307 kbps 的分组数据传输速率。
另一种从 CDMA/cdma2000 演变而来的技术是 1xEV-DO(1x Evolution, data only)。关于此项增强的 cdma2000 空中接口技术(优化了分组数据传输)的详细信息,请参见 Agilent 1xEV 技术页面
