    工信部正式向联通电信发放FDD-LTE牌照,全面进入4G规模商用时代

    工信部正式向联通电信发放FDD-LTE牌照 腾讯科技讯(郭晓峰 孙实) 2月27日,工信部正式发文,向中国电信(微博)、中国联通(微博)颁发了第二张4G业务牌照,即FDD-LTE牌照。由此,我国全面进入4G规模商用时代。 工信部称,根据相关企业申请,依据《电信条例》和《电信业务经营许可管理办法》,经过对申请企业财务能力、技术能力和运营能力等方面的综合审查,向中国电信和中国联通发放“LTE/第四代数字蜂窝移动通信业务(FDD-LTE)”经营许可,支持企业结合自身实际情况,统筹推进4G融合发展,促进信息消费。 2013年12月4日,工信部向中国移动(微博)、中国电信、中国联通分别颁发了第一张TD-LTE制式的4G牌照。目前,中国4G制式包括TD-LTE和FDD-LTE两种,FDD-LTE为欧美大多数国家的主流标准,TD-LTE是我国主导的标准。 从速率来看,理论上FDD-LTE要高于TD-LTE,但从部署上讲,TD-LTE又具备更好利用频谱资源的优势,适合密集区域的部署,所以两种制式各有优缺、不分伯仲。 中国移动是TD-LTE的主要推动者,去年可谓抢先一步发展。截止2014年年底的最新数据显示,中国移动的4G用户已经突破9000万户,4G基站数超过70万个,覆盖到县级,已建成全球最大的4G网。 相比之下,中国电信、中国联通虽也获得TD-LTE牌照,但从技术演进来看,FDD-LTE更符合其未来发展方向。据腾讯科技了解,过去的一年,这两家运营商向工信部申请发放FDD-LTE牌照工作从未停止过。 2014年6月27日,工信部批准中国电信、中国联通分别在16个城市开展FDD-LTE和TD-LTE混合组网试验,8月28日混合组网试验范围扩大至40个城市,12月18日又增加到56个城市。 在支持国家主导的TD-LTE同时,中国电信、中国联通也在积极部署混合组网,FDD/TDD融合组网成为未来趋势已是业界共识。目前,全球范围支持FDD-LTE的运营商超过300家,而支持TD-LTE的只有30家。 对于用户而言,多一种制式的4G网络,就是多一种4G服务,多样化的4G服务带来的竞争会使得资费更趋于平民化,从而推动4G更快速的普及。 按照三大运营商的整体规划,2015年我国4G用户有望达到4.5亿户,占到全国移动用户的三分之一。
