6 cities such as Hangzhou will be the first to experience this month 4G
Starting this month, 6 cities such as Hangzhou first experience 4G in the domestic network, but business should go, and so on; moving company said 4G fee certainly does not more expensive than 3G. April, the B1 in Hangzhou BRT line will open free 4G, Hangzhou became the first open city 4G network. However, at present, Hangzhou 4G network is still in the stage of experience, there is no real business. So did 4G really coming? 4G how far away from us?
Speeds two or three seconds a film on buffering
Reporter recently boarded B1 rapid buses, began a 4G tour. According to reports, China Mobile in front of B1 on the car and the bus station, with a wireless router, can be 4G into a WIFI signal. Car tips for mobile workers, journalists open WIFI, and connect to “CMCC-4G” on your wireless network, then the phone’s SaFaRi browser opens a Web page, mobile phone immediately jumped out “China Mobile communication 4G experience” page, click on the “experience”, you can connect to the Internet.
4G network is there any legend has it that fast? Reporter on PPTV video player, random opening film of the perfume of the city, three two-seconds buffer to complete. And the speed in 3G under the network environment it is difficult to achieve. Then, reporters download 4M songs of the not so simple, just points out the “Download” button, you hear “Ding” sound downloads.
It is understood that in the case of network signals good, 4G download 7M high quality songs just 1 second; a 700M CD only 2 minutes to download; downloads one of the 2.8G of the Encyclopedia Britannica, 8 minutes to complete downloading a 40G capacity of Blu-ray 3D film, family 4M broadband in General take a day to complete, but move 4G only two and a half hours.
However, journalists in the B1 when downloaded HD movies in the bus speed is not ideal, the average rate at around 450KB/S. Staff explained that at present on the B1 bus, 4G test speeds of up to 70M, generally stable at around 40M. As more people watch or download HD video at the same time, occurs too much pressure.
Spreading Hangzhou 6 cities continue to experience
According to the plan, in 10 4G a day in Hangzhou China Mobile speed construction of base stations, base station will be built by the end of the year 2000, is expected to cover downtown Hangzhou and Xiaoshan and Yuhang city, initially achieved nation-wide wireless high speed Internet access. At present, in addition to opening 4G in the B1 bus network, Bauhinia Hangzhou home communities as a pilot area first to enjoy a 4G network.
As a leading development of next-generation broadband mobile communication technology in China, TD-LTE in October 2010 by the International Telecommunications Union standards set for 4G technology. It is understood that apart from Hangzhou, Shanghai, Nanjing, Guangzhou, Shenzhen, Xiamen 5 cities 4G Web experience.
It is worth mentioning that, Zhejiang branch of China Mobile and Huawei jointly developed 3G to the smooth evolution of the 4G network, 4G network construction costs fell by 90%, also allows a single base station construction time was reduced from about 2 months to 3 days.
“Construction as the original independent network, and to increase the antenna and other equipment. Now this way, antenna and network devices can share, as long as the replacement circuit board, circuit boards and antennas placed between a small amount of fiber, can make the network upgrade. “China Mobile General Manager of Zhejiang Zhong Tianhua said.
Tariff not more expensive than 3G
4G subscription problem for Internet users are more concerned about, moving companies, as current Hangzhou 4G network still in the stage of experience, so 4G charge policy has not developed, but certainly not more expensive than 3G.
It is understood that 4G on the current international standards have both TD-LTE and FDD-LTE. FDD-LTE standard was formally commercial early last year in Europe and the United States. As of October 2011, 248 carriers around the world determined to deploy LTE commercial network planning, in which 35 network has been in business, there are 150 companies of commercial networks are deployed.
Although TD-LTE has been internationally recognized, but in our business processes were far behind Japan, and India and other countries. “The current international landscape, FDD technology business for nearly a year, access to TD technology and control equipment manufacturing enterprises are mainly Chinese companies, but these companies are busy taking on foreign orders. “Global network CEO Fang xingdong said,” 4G network of domestic horses need authorities ‘ whistle blowing ‘, otherwise the market will not start. ”
Experts suggest that given the 3G upgrade to 4G of the existing network of China Mobile costs can be substantially reduced, and China Unicom’s WCDMA network and Telecom CDMA2000 network, you can at very little cost to the smooth evolution 4G, 4 g, time is ripe for large-scale commercial applications. “We should seize the opportunity to promote 4G business as soon as possible, to seize the commanding point of global mobile Internet competition. “Fang xingdong said.
