部高清电影《Lifeline》，长度约 32 分钟，在千兆级LTE网络下，仅需15秒就能下载完成。这不是什么未来的商业技术，科技巨头正在把它变成现实。

在中国香港举行的高通4G/5G峰会上，高通发布了多项在千兆网络下的技术进展，比如最新5G原型测试手机就是运行在千兆网络上的，又比如高通正在联合运营商伙伴开发推动更多的新空口毫米波技术试验。高通执行副总裁兼QCT总裁克里斯蒂安诺·阿蒙表示，高通正在致力于提高全球消费者的移动宽带速度。

随着5G大门的打开，“速度”正在成为各家科技企业争夺的焦点，在争夺“速度”话语权的问题上，欧美巨头动作频频，中国厂商也不甘示弱。

据工信部披露，中国5G第三阶段测试将于2017年底启动，2018年相关运营商将进行预商用。机构数据显示，国内运营商在2018~2025年期间，5G宏基站投资规模总额约1.13万亿元，相比4G投入增长超过60%，小基站的总投资规模也有望超过2000亿元。

华为一位不愿透露姓名的内部人士对第一财经记者表示，随着千兆级的LTE走入人们的生活，如何真正打破网络容量限制、释放压抑的消费需求、探索新盈利增长点，成为通信行业厂商需要解决和努力的方向。

千兆网络即将到来

12年前，移动网络速率达到1.8Mbps，大家能用手机打开简易网页，但扩展功能非常有限。7年前，移动网络最高速率达到100Mbps，看图成为可能，TalkBox、微信等应用开始出现。今天，4G网络正不断进化，1秒打开图片和视频早已不在话下，还能用来导航和直播。

随着5G标准的即将落地，千兆级的网络也在临近。

一部时长为半小时的微电影“Lifeline”，分辨率为720P，大小约为140MB，用千兆级LTE网络不到15秒就下载完毕。按照这个速度，下完一整季美剧也就几分钟的事情。如果用4K的分辨率显示120帧每秒的360度全景VR视频，数据吞吐量是103Mbps，千兆级LTE的均速(114 Mbps)，完全可以实现视频VR直播。

高通认为，千兆级LTE标志着4G演进的下一阶段，它能带来更丰富的内容、全新的连接体验、App应用与使用模式。同时，作为与早期5G网络共存和相互配合的高速覆盖网络，千兆级LTE将是5G移动体验的一个重要支柱。而通过支持千兆级LTE网络的移动终端，用户的连接体验将得到显著提升，特别是在虚拟现实（VR）内容串流、云存储，以及高保真视频或音乐缓存等方面具有领先优势。

17日，高通在香港宣布，和Inseego子公司Novatel Wireless，展开基于5G新空口（5G NR）Release 15规范的5G新空口毫米波技术以及OTA外场试验。

高通发言人对记者表示，目前3GPP正在制定这一全球5G标准，三方计划联合推动移动产业生态系统实现5G新空口毫米波技术更快速地大规模验证和商用，从而支持在2020年前实现全面的商用网络部署。

而中国对于千兆级网络的重视程度也空前高涨。目前按照工信部的部署，三大运营商和相关通信公司早已积极开展了5G的研究和部署。

竞合中的较量

在推进5G标准的较量中，中美企业中最受关注的就是高通和华为。

不久前在捷克布拉格举行的3GPP RAN1 90会议上，举行了RAN1主席投票选举。经过两轮的不记名投票后，最终美国高通公司的Wanshi Chen（陈万士）当选为新一届RAN1主席。

当时争夺上述职位除了Wanshi Chen，还有来自华为的Brian Classon。有意思的是，Wanshi Chen是一名中国人，而华为的Brian Classon是一名外国人。

所以在通信圈子里流行着这么一句话，“本次3GPP RAN1主席选举，候选人分别是国外公司的中国人、中国公司的外国人，这意味着在5G技术基础研究和标准制定领域，中国人、中国公司已经成为第一流的贡献者。”

值得注意的是，去年11月17日，在3GPP RAN187次会议的5G短码方案讨论中，华为公司的Polar Code（极化码）方案成为5G控制信道eMBB场景编码最终方案，也是中国公司在5G标准制定阶段的一次胜利。

从追赶者到领先者，5G给了中国在移动通信领域赶超的历史机遇。

移动通信自20世纪80年代诞生以来，大概每十年会进行一代技术革新——从1G到4G，经历了从模拟到数字、语音到数据的演进，网络速率万倍增长。

对于中国而言，此前一直都是追赶者的角色，3G比海外商用晚八年左右，4G晚三年左右。随着2020年5G即将如期而至，移动通信网络变革大幕开启，中国主角时代或将来临。

中国5G推进组副主席、中国移动技术部总经理王晓云此前在一场技术峰会上表示，截至目前，我国已在怀柔建设了全球最大的5G试验网，其中有六家设备商（华为、中兴、大唐、爱立信、诺基亚、三星）参与，共有30个外场（5G）基站。而国内设备厂商测试的5G峰值速率达到10到20G，在高频可以达到21G，空口时延小于1毫秒，每平方公里连接可以达到150万。

按照目前中国5G技术的推进步伐，中国的技术研发推进会和国际5G标准的制定同步进行，2019年上半年完成5G技术研发试验阶段，进入产品研发试验阶段。而牌照的发放会在产品研发试验基本成形的阶段，5G的投资组网和商用会在2020年初左右，2020年对于中国厂商来说将会是5G元年，在那之前，一刻都不能放松。

The HD movie "Lifeline" is about 32 minutes in length and can be downloaded in only 15 seconds under the Gigabit LTE network. This is not the future commercial technology. Technology giants are turning it into reality.

At the high pass 4G/5G summit in Hongkong, China, Qualcomm has released a number of technological advances under the Gigabit network, such as the latest 5G prototype testing mobile phones that run on Gigabit networks, as well as Qualcomm is developing more new empty millimeter wave technology tests by joint operators partners. Cristiano Amon, executive vice president and chief executive officer of QCT, said that Qualcomm is working to improve the speed of mobile broadband for global consumers.

With the opening of the 5G gate, "speed" is becoming the focus of competition for all technology enterprises. On the issue of the "speed" discourse power, the European and American giants have been acting frequently, and Chinese manufacturers are not willing to be weak.

According to the Ministry of industry and information disclosure, the third phase of China's 5G test will start at the end of 2017, and the relevant carriers will be pre commercial in 2018. The organization data shows that the total investment scale of the 5G macro base station is about 1 trillion and 130 billion yuan during the 2018~2025 period, and the total investment scale of the small base station is also expected to exceed 200 billion yuan, compared with the increase of more than 60% of the 4G investment.

HUAWEI, an unnamed insider, told first financial reporters that as the Gigabit LTE entered people's life, how to truly break the network capacity limit, release the repressed consumption demand and explore new profit growth points, has become the direction for the telecommunications industry manufacturers to solve and work hard.

The Gigabit network is coming

12 years ago, the mobile network rate reached 1.8Mbps. We could use mobile phones to open simple web pages, but the expansion function was very limited. 7 years ago, the mobile network reached the highest rate of 100Mbps, and it was possible to see the picture. TalkBox, WeChat and other applications began to appear.  Today, the 4G network is evolving. It has been a long time to open pictures and videos in one second, and it can also be used for navigation and live broadcasting.

With the coming of the 5G standard, the Gigabit level network is also approaching.

A half hour movie called "Lifeline", with a resolution of 720P and a size of 140MB, will be downloaded in less than 15 seconds with a Gigabit LTE network. At this rate, a few minutes of the whole season will be finished. If the resolution of 120 frames per second 360 degree panoramic VR video is displayed with the resolution of 4K, the data throughput is 103Mbps, and the average speed of the Gigabit LTE (114 Mbps) can fully realize the video VR live broadcast.

Qualcomm believes that Gigabit LTE marks the next stage of 4G evolution. It can bring richer content, new connection experience, App application and usage mode. At the same time, as a high-speed overlay network coexisting and cooperating with the early 5G network, Gigabit LTE will be an important pillar of 5G mobile experience. By supporting the mobile terminals of Gigabit LTE networks, the user's connection experience will be significantly improved, especially in the VR content stream, cloud storage, and high fidelity video or music caching.

On the 17 day, Qualcomm announced in Hongkong, and Inseego subsidiary Novatel Wireless, to launch the new 5G empty millimeter wave technology based on the 5G NR Release 15 specification and the OTA outfield test.

High pass spokesman told reporters that the 3GPP is currently working on this global 5G standard, and the three party program jointly promotes the mobile industrial ecosystem to realize 5G new empty millimeter wave technology more quickly and large-scale verification and business, so as to support the implementation of a comprehensive commercial network deployment by 2020.

China's attention to Gigabit networks is also unprecedented. At present, according to the deployment of the Ministry of industry and information technology, the three operators and related communication companies have already actively carried out the research and deployment of 5G.

Competition in competition

In the contest to promote the 5G standard, China and the US are most concerned about Qualcomm and HUAWEI.

Shortly after the 3GPP RAN1 90 conference held in Prague, Czech, the presidential election of RAN1 was held. After two rounds of secret ballot, the US Qualcomm Corp's Wanshi Chen (Chen Wanshi) was finally elected as the new RAN1 chairman.

At that time, competition for the above positions included Wanshi Chen and Brian Classon from HUAWEI. What is interesting is that Wanshi Chen is a Chinese, while HUAWEI's Brian Classon is a foreigner.

So in the circle of communication, "3GPP RAN1 chairman election, the candidates are foreign companies of Chinese, Chinese companies, foreigners, which means that in the field of 5G technology basic research and standard setting, Chinese and Chinese companies have become a first class contributor."

It is noteworthy that in November 17th last year, HUAWEI's Polar Code (polarization code) scheme became the final solution to the 5G control channel eMBB scene coding in the 5G short code scheme discussion at the 3GPP RAN187 conference, and also a victory for the Chinese company in the 5G standard setting phase.

From the pursuer to the leader, 5G has given China a historical opportunity to catch up with the mobile communications industry.

Since the birth of mobile communications in 1980s, about every ten years, a generation of technological innovations - from 1G to 4G - has experienced an evolution from analog to digital, voice to data, and the network rate has grown tens of thousands of times.

For China, it has always been the pursuer's role. 3G is eight years late than overseas business, and 4G is about three years late. With the coming of 5G in 2020 and the opening of mobile communication network, the Chinese protagonist era will come.

Wang Xiaoyun, vice president of China 5G propulsion group and general manager of China Mobile Technology Department, said at a technical summit that as of now, China has already built in Huairou.
