通信世界网消息(记者 杨海峰)CDMA发展集团（CDG）和国际CDMA450行业协会（IA450）今日联合宣布，在新兴、发达和竞争高度激烈的无线通讯市场，由于CDMA450技术可满足人们对负担得起的3G服务的需求，该技术正在世界各地区迅速扩展。目前有来自60个国家的103家运营商已经或计划部署CDMA450服务，其中36个国家的67家运营商已经开始为全球各地超过1200万人提供商业服务，另外24个国家中共有36个CDMA450网络正在测试或部署之中。CDMA450是一项3G解决方案，它结合了下一代CDMA2000无线通讯服务与经济上可承受的、使用450MHz频段的网络覆盖。

    CDMA发展集团执行总监佩里·拉佛尔吉（PerryLaForge）表示：“CDMA发展集团很高兴报告CDMA450的持续拓展。现已证明该技术具备竞争力，能够满足低收入市场对可承受的语音及宽带数据服务的需求。由于成本所限，传统上这些市场是其它技术无法进入的。”

    国际CDMA450行业协会主席维迪姆·贝尔雅夫斯基（VadimBelyavskiy）评价说：“CDMA450的优点多多，其中就包括射频传播特性。在人口稠密的城市化地区，室内穿透覆盖很重要，CSMA450的射频传播特性可优化这些地区的的3G服务投放，同时，对于大范围覆盖至关重要的农村地区，它也可以改善此类地区的服务。我们很高兴这一技术被迅速接受。在连接尚未享受无线通讯的40亿人口中大多数人的角逐中，CDMA450技术已成为全球性的竞争者。”

    大多数CDMA450运营商采用CDMA20001X技术提供电话通讯和高速数据服务，其中多达40家企业选择了CDMA20001XEV-DO系统为客户提供无线宽带数据服务。今年CDMA20001xEV-DORevA技术出台后，CDMA450运营商将可为客户提供高性能、低延迟、上行密集型的服务，如电信运营级VoIP语音电话、一键通（push-to-talk）、视频电话、增强型多媒体信息、组播以及下一代宽带技术。

    阿根廷、中国、印度尼西亚、墨西哥和俄罗斯等大规模市场，已将450MHz频段分配给民用的通用电话和因特网接入。对CDMA450语音、多媒体和宽带数据服务的强烈需求可望持续。业经证明，CDMA450技术的灵活性足以为各类地区提供全移动或固定的无线本地环路（WLL）服务，这些地区大到西藏，小至位于秘鲁安第斯山脉间的遥远村落（普埃布洛印地安人部落）。

    CDMA450基础设施设备目前由一些领先制造商提供，包括阿尔卡特——朗讯（Alcatel-Lucent）、华为、北电网络（Nortel）、UT斯达康（UTStarcom）和中兴通讯。这一行业中也有大量价格可承受的设备和服务可供选择。包括AnyData、Axesstel、Curitel/Pantech、华为、京瓷株式会社（Kyocera）、LG、Ubiquam和中兴通讯等十余家公司可提供约100种CDMA450设备，包括移动电话、固定式无线终端、固定式无线电话、PC扩展卡、ThumbdriveUSB优盘、Wi-Fi路由器、POS终端以及防震式应急人员通讯设备。CDMA450设备具备全部3G特性，包括照相机、MP3音乐播放器、摄像机、GPS定位、一键通、蓝牙连接技术和R-UIM卡。

    为提升CDMA450的价值，CDMA2000行业现正努力拓展CDMA450设备的范围，降低成本，并实现跨标准全球漫游。CDMA发展集团和国际CDMA450行业协会与运营商和设备制造商一道，已制定了针对入门级CDMA450设备的一整套通用标准，使运营商可以合并采购，享受批量折扣。为扩展漫游，CDMA2000行业已开发出多模式、多频段的CDMA450/GSM900/1800设备，现正开发CDMA450/2100MHz设备。为应对极低端的市场，很多此类设备将采取单芯片组解决方案，进一步降低成本，降幅最高可达50％。

    在450MHz频段部署CDMA2000技术的国家，可享受3G技术在改善个人生活方式和提高商务生产率方面的优势，尤其是在低频段。因为在这一频段，陆上通讯线服务不易获得，而语音业务量则较高。下表列出了这些国家：
