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 Keysight 1xEV 技术页面

是德科技公司为工程师和技术管理人员提供 cdma2000/CDMA 产品、解决方案和服务,帮助他们进行下一代网络的设计、集成、制造和性能优化。深入分析。增强信心。加快下一代无线技术的发展。
