中国移动选定7家供应商参加TD-LTE试验

在宣布计划扩大TD-LTE试验网络两个月之后，中国移动本周表示，将有7家供应商为这种先进网络提供设备，但中国移动未披露将如何分工。 中兴通讯和阿尔卡特-朗讯在一天后急忙宣布，都从中国移动赢得了一项TD-LTE合同。中国移动是全球第二大无线网络运营商。 其它为TD-LTE网络提供设备的中标企业包括：华为，爱立信，诺基亚西门子通信(MSN)，New Postcom Equipment Co.和大唐移动。 据报道，中国移动的这次招标内容包括大约2万个基站和5.2万个载频。中国移动这次采购的TD-LTE设备将用于在13个中国城市扩大TD-LTE试验网络。 中兴透露其将在五个中国城市建设中国移动的TD-LTE网络：北京，天津，广州和沈阳。其中将包括1.3万个以上的载频。 阿尔卡特-朗讯表示赢得一项合同，占TD-LTE试验网络基站的最大份额。根据这项合同，阿尔卡特-朗讯的中国子公司上海贝尔将在2013年初在上海、南京和青岛提供大约3千个基站。 中国移动拥有7亿多个用户，一直在积极扩大TD-LTE试验网络。到2012年底，试验网络将布署2万个基站，覆盖总计人口达1.5亿人的13个城市。 随着智能手机需求激增，中国移动急于推出TD-LTE网络。据市场调研公司Gartner，中国是全球最大的智能手机市场，占全球智能手机出货量的四分之一。 中国在移动数据服务方面也领先于全球市场。阿尔卡特-朗讯表示：“阿尔卡特-朗讯布署的新的TD-LTE网络，将提高中国移动的网络速度、容量和质量。”该供应商亦表示，它也将让中国移动能够缩小设备尺寸和降低功耗。 与中国的TD-SCDMA标准相比，推出TD-LTE是为了提供全IP能力、更快的响应时间和更低的延时，最大数据下载速度高达100 Mbit/s。 中国移动与日本软银都在兴建TD-LTE网络。软银本周以201亿美元收购美国移动运营商Sprint Nextel 70%股份，这是迄今日本企业收购外国公司交易的最大规模。 本文授权编译自EE Times，版权所有，谢绝转载 编译：Luffy Liu 参考英文原文：China Mobile selects 7 suppliers for TD-LTE trial, by Junko Yoshida

{pagination} China Mobile selects 7 suppliers for TD-LTE trial Junko Yoshida Two months after announcing plans for an expanded TD-LTE trial network, China Mobile said this week that seven manufacturers will supply gear for the advanced network, but stopped short of disclosing how the work will be divided. A day later, ZTE and Alcatel-Lucent raced to announce that each had won a TD-LTE contract from the world???s largest cellular network operator. Other winning bidders to help build the TD-LTE network include: Huawei Technologies, Ericsson, Nokia Siemens Networks (NSN), New Postcom Equipment Co. and Datang Mobile Communications Equipment Co. (Datang Mobile). China Mobile???s tender reportedly included contracts for some 20,000 base stations and 52,000 carrier sectors. The TD-LTE devices purchased by China Mobile will be deployed in an expanded TD-LTE trial network in 13 Chinese cities. ZTE revealed that it will construct China Mobile???s TD-LTE networks in five Chinese cities: Beijing, Tianjin, Guangzhou, Shenzhen and Shenyang. They will include more than 13,000 carrier frequencies. Alcatel-Lucent said it won a contract to deliver ??úthe largest share of basestations??ù for TD-LTE trial network. Under the contract, Alcatel-Lucent Shanghai Bell, Alcatel-Lucent???s China subsidiary, will supply about 3,000 basestations in Shanghai, Nanjing and Qingdao in early 2013. With more than 700 million subscribers, China Mobile has been aggressively pursuing an expanded TD-LTE trial network. By the end of 2012, the trial network will deploy 20,000 basestations covering 13 cities with a combined population of 150 million people. China Mobile is in a hurry to roll out TD-LTE networks as smartphone demand soars. China is the world???s largest smartphone market, accounting for one-quarter of global smartphone shipments, according to market researcher Gartner. China also leads the global market for mobile data services. "The new TD-LTE network deployed by Alcatel-Lucent will increase the speeds, capacity and quality of China Mobile's network,??ù Alcatel-Lucent claimed. It will also give China Mobile the ability to operate with a smaller footprint and lower power consumption, the supplier added. Compared to China's TD-SCDMA spec, TD-LTE is designed to offer full IP capability; faster response time and lower latency, with peak downlink data rates of 100 Mbit/s. TD-LTE networks are being built by both China Mobile and Japan's Softbank. Softbank this week reached a deal to buy 70 percent of U.S. mobile carrier Sprint Nextel Corp. for $20.1 billion in the largest ever foreign acquisition by a Japanese company.
