Hangzhou has become the first 4 G network experience of open city(转载) - 大卫 - 峰回路转
4月起,杭州B1快速公交线将免费开放4G网络,使杭州成为中国第一个开放4G网络的城市。不过,目前,杭州的4G网络仍处于体验阶段,并没有实现真正商用。那么,4G时代真的将要到来了吗?4G离我们到底有多远?

 4 month, hangzhou B1 express bus lines will open for free 4 G network, make hangzhou China's first 4 G network open city. However, at present, hangzhou's 4 G network is still at the stage of experience, and didn't realize real commercial. So, 4 G era really coming? 4 G away from us exactly how far?

4G有多快?记者公车体验4G之旅

 4 G how fast? Reporter bus tour of the 4 G experience

3月30日下午,记者登上B1快速公交车,开始了4G体验之旅。据介绍,中国移动在B1的车头车尾以及公交站台上,都安装了无线路由,可以将4G网络转化成WIFI信号。据车上移动工作人员的提示,记者打开WIFI,连接到“CMCC-4G”的无线网络上,再用手机自带的SaFaRi浏览器打开网页,手机上马上跳出“中国移动通信4G网络体验”的页面,点击“开始体验”,就能上网了。

 30 March afternoon, the reporter on B1 rapid bus, the beginning of a journey of experiences 4 G. According to introducing, China mobile in the rear and front B1 bus on the platform, which are installed wireless routing, can will have 4 G network into a WIFI signal. According to the mobile workers of the tip, the reporter open WIFI, link to "CMCC-4 G" wireless network, and then to own SaFaRi browser with mobile phone open the page, on the phone immediately jump out of "China mobile communications 4 G network experience" page, click on the "start to experience", it can connect to the Internet.

4G网络到底有没有传说中那么快?记者打开PPTV视频播放器,随机点开一集电影《芳香之城》,三两秒便缓冲完成。而这样的缓冲速度,在3G网络环境下是很难实现的。接着,记者在百度MP3下载了一首4M大的《没那么简单》,刚点完“下载”按钮,就听到叮的一声,下载完成。

 4 G network exactly have legend so fast? Reporter PPTV video player open, random PM on a movie set the fragrant city ", three two seconds and buffer completed. And this kind of buffer speed, on the 3 G network environment is hard to realize. Then, the reporter in baidu MP3 download a 4 M big "not so simple", just point over "download" button, you hear a sound bite, download the complete.

据移动公司的技术人员介绍,在网络信号良好的情况下,4G网络下载一首7M大小的高品质歌曲只需1秒钟;下载一张700M的CD只需2分钟;下载一部2.8G的大英百科全书,8分钟可以完成;下载一部40G容量的蓝光3D影片,一般的家庭4M宽带需要一天完成,但移动4G只需要两个小时的时间。

 According to mobile company technical personnel introduces, in network signal favorable conditions, 4 G network download a 7 M size of high quality songs just 1 second; Download a 700 M CDS for just two minutes; Download a 2.8 G encyclopedia britannica, eight minutes can complete; Download a 40 gb capacity of the blu-ray 3 D movie, the average family 4 M broadband need a days to finish, but 4 G mobile need only two hours.

不过事实上,记者在B1车上下载高清电影时,速度并不理想,平均速率在450KB/S左右。工作人员解释说,目前在B1公交上,4G测试网速最高可以达到70M,一般稳定在40M左右。如车上多人同时在观看或下载高清视频,会出现网络压力过大的情况,在一定程度上影响网速。不过,一般的刷微博,上QQ,看网页等操作,一车人即使同时进行也没有问题。

 But in fact, the reporter in the high-definition movie download B1, speed is not ideal, average rate in 450 KB/S or so. The officials explained that is currently in the B1 bus, 4 G speeds can reach the highest test 70 M, general stability in 40 M or so. If the car at the same time in the people watching or download the hd video, can appear network pressure situation, to some extent speeds. However, the general brush micro bo, on QQ, see page operation, even if one is a car at the same time is no problem.

平滑演进技术加速4G网络城市建设

 Smooth evolution technology to accelerate 4 G network city construction

记者了解到,从去年6月起至今,杭州已经在黄龙、武林商圈以及B1快速公交沿线等人口密集区域建了几百个4G试验基站。根据规划,中国移动在杭州地区将以每天10个4G基站的速度建设,到今年年底将建成2000个基站,预计可以覆盖杭州主城区以及萧山、余杭主城区,初步实现全民无线高速上网。 目前,除了在B1公交车上开通4G网络之外,杭州紫荆家园小区也作为试点区率先享受到了4G网络。

 Smooth evolution technology to accelerate 4 G network urban construction the reporter understands, since last June up to now, hangzhou has been in huanglong, wu3 lin2's business circle and B1 bus rapid transit and along the densely populated areas built hundreds of 4 G test base station. According to the plan, China mobile in hangzhou area will be 10 4 G base station every day of the construction speed, by the end of this year will be 2000 a base station, can be covered hangzhou city and is expected to xiaoshan, yuhang downtown area, realize the preliminary wireless high-speed Internet access. At present, in addition to the 4 G B1 bus open network besides, hangzhou traversing cercis chinensis home village as well as enjoy the 4 G experimentsite area to take the lead in the network

作为我国主导开发的新一代宽带移动通信技术,TD-LTE已于2010年10月被国际电信联盟最终定为4G技术标准。据了解,除了杭州,已经开展TD-LTE规模技术试验的上海、南京、广州、深圳、厦门5个城市也将随后开展4G网络体验。

 As a leading our country development of a new generation of broadband mobile technology, TD-LTE already in October 2010 by the international telecommunication union eventually as 4 G technology standards. According to information, in addition to hangzhou, have launched TD-LTE technology test scale of Shanghai, nanjing and guangzhou, shenzhen, xiamen five cities also will then carry out 4 G network experience.

值得一提的是,中国移动浙江分公司与华为技术有限公司共同研发出的3G向4G网络的平滑演进技术,使4G建网成本下降了90%,也使单个基站的建设时间从2个月左右缩减到了3天。

 Be worth what carry is, China mobile zhejiang branch and huawei technologies Co., LTD. Jointly developed 3 G to 4 G network smooth evolution technology, make arrangement 4 G costs fell 90%, also make a single base station construction time from 2 months to three days or so reduction.

“按照原有的独立建网的建设方式,要增加天线和其它设备,现在这种方式,原来的天线及网络设备均可以共用,只要更换电路板,在电路板和天线之间布放少量的光纤,就能实现网络升级,”中国移动浙江公司总经理钟天华告诉记者,“通过少量的设备更新和软件升级,可以实现在一个基站同时运行3G和4G两套网络。”

 "According to the original independent construction method, the arrangement to increase the antenna and other equipment, now this way, the original antenna and network equipment are can share, should change in circuit board, and between a small amount of optical fiber cloth antenna, we can realize network upgrades," China mobile zhejiang clock our general manager told reporters, "through a small amount of equipment renewal and software upgrade, can achieve in a base station to run 3 G and 4 G two sets of network."

真正的4G时代离我们有多远?

 The real 4 G time away from us how far?

对于网民们比较关心的4G资费问题,移动公司表示,由于目前杭州的4G网络还处于体验阶段,尚未真正商用,所以,目前4G的收费政策还没有制定,但“肯定不会比3G贵”。还有不少网民关心,除了杭州之外,其他城市什么时候才能享受到4G网络,真正的4G时代什么时候能到来?这些问题,目前尚未有明确答案。

 For Internet users are more concerned with 4 G of price problem, mobile company said, because at present hangzhou's 4 G network is still in the stage of experience, has not really commercial, and so, at the moment, 4 G charging policies have not been set, but "won't than 3 G expensive". And many Internet users care, in addition to hangzhou, others besides when city to enjoy the 4 G network, the real 4 G era when can come? These problems, is not yet a clear answer.

据了解,目前国际上的4G通信标准有TD-LTE和FDD-LTE两种。FDD-LTE标准已于去年年初在欧美国家正式商用。截至2011年10月,全球有248家运营商已经确定了部署LTE商用网络的计划,其中,35张网络已正式商用,还有150家公司的商用网络正在部署。

 According to information, the international 4 G standard of communication have TD-LTE and FDD-LTE two kinds. FDD-LTE standard already in the beginning of last year in the European and American countries formally commercial. By October 2011, around 248 operators have confirmed the deployment of the commercial LTE network plan, among them, and a network has been officially commercial, and 150 companies in the commercial network are deployed

虽然TD-LTE已经受到了国际认可,但是在我国的商用进程却远远落后于日本、印度等国家。截止2011年10月底,全球TD-LTE共签署12个商用合同,华为获得其中的8个,在国外承建了包括日本、波兰、沙特、英国、尼日利亚等多个国家的TD-LTE网络。

 Although TD-LTE is under the international recognition, but in our commercial process but far behind Japan, India and other countries. By the end of October 2011, global TD-LTE commercial contract signed with 12, huawei access to one of the eight, in foreign construction of including Japan, Poland, Saudi Arabia, Britain, Nigeria and other countries of TD-LTE network.

“目前国际上的格局是,FDD技术已商用近一年,掌握TD技术和控制装备生产的企业主要是中国企业,但这些企业也忙于承接国外订单,”全球网总裁方兴东说,“国内的4G网络上马需要主管部门‘吹哨子’,这个哨子不吹,这个市场是不会启动的。”

 "The international pattern is FDD technology has commercial, nearly a year, master TD technology and control equipment production enterprise mainly Chinese enterprise, but these enterprises also busy to undertake foreign order," global net President square interest east said, "domestic 4 G network to mount competent departments' blowing his whistle, 'the whistle don't blow, this market is won't start."

有专家建议,鉴于中国移动现有的3G升级到4G网络的费用可以大幅缩减,而联通的WCDMA网络和电信的CDMA2000网络本身就可以以极少的代价向4G平滑演进,我国将4G进行大规模商业化应用的时机已经成熟。“我们应抓住机遇,尽快推进4G商用,抢占全球移动互联网竞争制高点,为移动互联网产业创新乃至整个经济转型奠定基础。”方兴东说。

 Experts suggest, in view of China mobile existing 3 G to upgrade to the cost of the 4 G network may significantly reduced, and the WCDMA network and telecom unicom of CDMA2000 network itself can with very little cost to 4 G smooth evolution, our country will be 4 G for large-scale commercial application of the time is ripe. "We should seize the opportunity, 4 G as soon as possible, and seizes of commercial global mobile Internet competition commanding heights, for mobile Internet industry innovation and the entire economic transformation lay the foundation." Square interest east said.
