GSM、GPRS、EGPRS 和 EDGE/Evo

GSM 是一项覆盖范围广、扩展迅速的成功技术。最初的数据限制已在 2000 年发布的 GPRS 版本中得到解决,这种分组交换功能使手机用户可以浏览网页。GSM 是第一种数字蜂窝系统。EGPRS、EDGE 和 EDGE/Evo(统称 2.5G 无线技术)为 2G(第二代)无线技术提供了升级途径,以达到更高的数据速率。EDGE/Evo 是 GSM 手机标准的最新发展。用户通过软件升级和使用新的设备,能够将数据速率提升至接近 1 Mbps。这些技术已在全球得到部署。

尽管技术已经成熟,但对于商用产品的要求仍然很高。因此,GSM、GPRS、EGPRS 和 EDGE 蜂窝系统的开发人员、验证工程师和生产管理人员必须快速为市场提供经济高效的高质量产品。作为全球测试与测量解决方案的领导者,是德科技公司可提供广泛的建模、开发和测试工具,帮助您确保系统和元器件的质量。深入分析。增强信心。加快下一代无线技术的发展。
