1、 IDEN测试系统介绍IDEN测试系统介绍Date1一. iDEN 的历史 iDEN Integrated Digital Enhanced Networks 增强型数字网络。 iDEN 系统于1994年在美国洛杉矶问世，是由摩托罗拉公司提出的 一种数字集群制式，工作于800MHz 频段范围，它的主要特点是可 以和GSM 兼容，适合组大网。 二. iDEN 在世界的应用 目前在北美、南美及亚洲十三个国家投入商业应用。全球iDEN 用户 已超过1000万。摩托罗拉的iDEN 系统在亚洲也取得了巨大发展， 其中包括与韩国仁川国际机场，中国深圳和上海等有关单位签署 的合同以及在日本、菲律宾、韩国，新
2、加坡和中国福建等地正在 运行的iDEN 网。 三. iDEN 在中国的应用 2000 年12 月28 日，信息产业部正式批准和发布的我国“数字集群移 动通信系统体制“电子行业推荐性标准中，确定了两种体制，即 iDEN 和TETRA 两个数字集群通信系统体制，是国内的推荐性行业 标准。已经建好的有福建省集群通信公司和深圳市运输局的两个 iDEN数字集群通信网。正在建设的有上海联通国脉iDEN数字集群 通信网，北京的一个Harmony 网。重庆，江苏、浙江、广东、陕 西，内蒙古等地也都表示要建设数字集群通信共网。可以说，数 字集群移动通信共网将在我国进入大规模建设时期。 IDEN 数字集群通信系统
