On the afternoon of June 27th, China Unicom finally looked forward to the experimental license of hybrid networking. The Ministry of Industry and Information Technology approved China Unicom to build LTE networks in Shanghai, Guangzhou, Shenzhen, Chongqing, Zhengzhou, Wuhan, Chengdu, Xi 'an, Changsha, Jinan, Hangzhou, Shenyang, Harbin, Fuzhou, Nanjing, Shijiazhuang and other cities 16, and to carry out TD-LTE/LTE FDD hybrid networking experiments. Although it is not a formal commercial license for FDD-LTE, it also marks the official start of commercial trial of FDD-LTE network.

As of August 28th, China Unicom was approved to expand the experimental scope of TD-LTE/LTE FDD hybrid networking, adding 24 cities, namely: Beijing, Tianjin, Suzhou, Qingdao, Dongguan, Dalian, Ningbo, Changchun, Haikou, Taiyuan, Nanning, Yantai, Xiamen, Kunming, Hefei, Guiyang, Luoyang, Tangshan, Hohhot, Yulin and Lanzhou. So far, the number of cities where China Unicom can carry out LTE FDD standard 4G services has increased to 40. At present, the construction of Unicom's 4G city is as follows:

Shanghai Unicom 4G Covers High Speed Rail

On June 27th, China Unicom obtained the experimental license of hybrid networking, and Shanghai Unicom completed the FDD upgrade of the whole network. According to Deng Xuan, deputy general manager of Shanghai Unicom, it has been publicly disclosed recently that Shanghai Unicom has built more than 4,000 FDD-LTE 4G base stations, and the 4G signals in Shanghai's outer ring and suburban key towns are good. It is planned to reach 6,000 base stations by the end of the year, basically completing 80% of Shanghai's regional coverage. At the same time, the network speed is measured within the coverage of city Unicom's 4G, and the download speed reaches 60-80Mbps, and the upload speed exceeds 10Mbps.

Through the three-way comparison test, Shanghai's 4G network coverage, voice quality, data rate and other indicators are leading. In addition, in May this year, Shanghai Unicom partially withdrew from the 2G network and took out 10 MHz resources to merge into the FDD network to expand the FDD bandwidth. Add the original 10 MHz of FDD, and expand the original 10 MHz bandwidth of FDD to 20MHz.

Recently, the reporter measured the speed of Shanghai Unicom's 4G network on the high-speed railway with a speed of 300KM/h, and found that the download speed can still reach about 10Mbps, which means that the actual download speed can exceed 1M/s, which can meet the needs of business people to quickly collect all kinds of daily mail documents. When it dropped to about 250KM/h at that time, the download speed quickly increased to nearly 20Mbps, or prompted more Beijing-Shanghai business people to choose high-speed rail in the future.

Nanjing rapidly promotes 2G network withdrawal and expands bandwidth resources for FDD.

Nanjing Unicom launched a 4G upgrade experience, and the highest peak rate of 4G network can reach 150Mbps. As of July 1, 53 1 LTE stations have been opened, realizing contiguous coverage of key areas such as the main city (within the Ming city wall), Xianlin University Town, Jiangning University Town and Airport Expressway. At the same time, Nanjing Unicom is actively optimizing the network, and has completed the verification test of all 53 1 LTE sites and the cluster optimization adjustment of 10 area. At the same time, it is found that the speed of Nanjing high-speed railway is 302KM/h, the download speed is still 9.48Mbps, and the upload speed is 5.5 1Mbps.

According to Nanjing Unicom, as early as 20 13, Nanjing Unicom has started the planning and preparation of LTE. At the same time, in order to make up for the shortage of LTE FDD spectrum resources, Nanjing Unicom completed the frequency down and over-frequency of the whole network DCS 1800M network in less than 10 days. In the actual network speed measurement, the peak download rate of LTE FDD is greater than 142Mbps.

In addition, Jiangsu Unicom's Internet Office introduced a prepaid 180 yuan phone bill 150:50 card purchase fee+100 yuan number selection fee, and 150 yuan was returned as a one-time phone bill. Buy a free combination package and give 30 yuan electronic recharge card. If you only open the 8 yuan traffic package, the phone bill of 180 yuan can be used for 2 years.

The coverage of 4G networks in Guangzhou and Shenzhen is equivalent to that of 3G.

On July 16, Guangdong Unicom upgraded its 4G network. By the end of July, Guangdong Unicom's personnel in charge of network construction revealed that "the number of Unicom's 4G base stations in Guangzhou and Shenzhen has been equivalent to that of 3G, which means that 4G coverage has reached the 3G level". At present, the number of 3G base stations in Guangzhou and Shenzhen Unicom has exceeded 1 10,000, with a coverage rate of 99%. According to a person in charge of network construction of Guangdong Unicom, "Now there are more than 3,000 people in charge of 4G construction in the province, all of whom are working overtime, even faster than when building 3G".

It is understood that users who used to access Unicom's 4G/3G integrated package and users who freely combined packages can already use 4G mobile phones to search Unicom's LTE signals. After Guangdong Unicom fully upgraded 4G on July 16, users can purchase 4G cards and mobile phones in various business halls (including social cooperative stores) and online business halls of Guangdong Unicom, and then they can experience the highest 150Mbps 4G network. Unicom's 4G package only needs 56 yuan, including 400 MB 3G/4G integrated traffic and 200 minutes of calls.

In addition, Guangdong Unicom currently sells more than 40 4G terminals, and more than 30 will be listed in August, covering mainstream brands at home and abroad, including iPhone, Samsung, Huawei and Lenovo.

In the field test, indoor fixed-point tests in Guangzhou, Shenzhen airport, railway station, shopping center, five-star hotel and high-end office building are close to 100M, while the speed measurement in Tianhe City and China Plaza reaches 130Mbps and 140Mbps. At the same time, the road test coverage rate in Guangzhou and Shenzhen has reached 95%.

Zhengzhou Unicom held a 4G tasting meeting.

On August 1 1, Zhengzhou Unicom held a 4G tasting meeting, and announced that as the first pilot city, it had completed the upgrade of dual 4G networks, and the network speed increased to 150Mbps. Li Zhanwei, general manager of Zhengzhou Unicom, delivered a speech on the spot, introducing the core network speed of China Unicom's 4G "fast, wide, multi-service, excellent and good".

It is reported that the average download speed of China Unicom's 4G is 1 10Mbps in recent fixed-point tests in urban areas and counties. The test was carried out on a high-speed vehicle with an average download speed of 60Mbps. At present, Zhengzhou county and above have achieved full coverage, and it is expected that the full coverage of township areas will be completed this year.

In addition to expanding the coverage of the 4G network, Zhengzhou Unicom is also stepping up the construction and optimization of the 4G network, making every effort to build a 4G boutique network, further strengthening the deep coverage of some public areas such as commercial buildings, subways, airports and scenic spots, and making the 4G network "into the ground".

Wuhan's lowest 4G tariff dropped to 8 yuan.

On July 28th, Wuhan Unicom's 4G was fully upgraded. From now on, users can officially use Unicom's 4G with peak rate 150Mbps. Old users can upgrade smoothly without changing their cards and numbers, and the original package needs to be upgraded to a 4G/3G integrated package. In addition, Unicom's free combination packages such as traffic and voice can be customized as required, and 8 yuan can enjoy the domestic traffic of 100MB per month at the minimum, which is also the 4G package with the lowest threshold at present.

At present, China Unicom has listed a number of 4G mobile phones, which support four network modes: TDD, FDD, WCDMA and GSM, and all of them have opened FDD networks. This year, China Unicom will launch more than 150 4G terminals.

Mobile phones cover Nokia, Samsung, Sony, Huawei, Coolpad, Tianyu and other brands, including Samsung S5, Note3, HTC One Huawei P7, Glory 3C LTE and other star models.

"I am a traveler" Hangzhou Unicom 4G boosts Hangzhou's "smart tourism"

On September 1 day, Zhejiang Unicom and Hangzhou Tourism Commission held a three-month theme activity in Hangzhou to promote "smart tourism". During these three months, participants were encouraged to visit the beautiful scenery of Hangzhou through smart tourism through the three themes of "eating Jianghu things", "romantic encounter" and "slow life in Hangzhou", and the micro-video of the food and beautiful scenery that best represents Hangzhou's personality was shot with mobile phones and shared with you, showing the beautiful Hangzhou and letting millions of netizens feel the street culture and unique romantic leisure atmosphere of Hangzhou.

All of this will rely on Unicom's 4G ultra-fast network to meet a series of needs such as "eating, living, traveling, shopping, entertainment and showing" in the travel itinerary through various APP applications.

In terms of traffic, the double-capping rule of traffic and reassuring function are introduced. That is, after the out-of-package traffic is charged to 600 yuan, the domestic (excluding Taiwan, Hong Kong and Macao) traffic is no longer charged, and the data network 15GB is automatically closed and opened the next month. After the user actively applies, the data network can be opened in the month, and the subsequent traffic will continue to use the rest assured function. When the total data traffic (including various charges, free and directional traffic inside and outside the package, including international and roaming traffic in Taiwan, Hong Kong and Macao) reaches 40GB, the system will automatically shut down the data network, which will not be opened in the current month and will be automatically opened next month.

Shijiazhuang, Baoding, Tangshan and Qinhuangdao have opened more than 2,000 4G base stations.

Hebei Unicom's 4G network was fully opened in the whole province 1 1 city, which marked that the construction of Hebei Unicom's 4G network has crossed a milestone after completing the data migration of 24 million mobile phone users from HLR to HSS in the whole province.

According to statistics, up to now, Hebei Unicom has opened more than 2,600 4G base stations, of which the total number of 4G base stations opened in 56 key cities in China, Shijiazhuang, Baoding, Tangshan and Qinhuangdao, has exceeded 2,000, basically achieving full coverage of the central city and hot experience areas. The province-wide network road test and bill verification show that the voice fallback function of 4G users from LTE network to WCDMA network is normal and the interworking between U/L networks is smooth under the overlapping coverage area of WCDMA/LTE networks. Under the current light load environment of 4G network, the average download rate of 4G terminals can easily reach about 90Mbps, and the download of 3GB HD movies can be completed in 5~ 10 minutes, and the network speed is beyond imagination.

Fujian Unicom's "Great Joy"

In terms of network coverage, Fujian Unicom has built an ultra-wide coverage wireless network. According to the feedback from Fujian Unicom users, when riding Unicom EMU, you can surf the Internet smoothly even through tunnels and complex and remote terrain, which is infinitely close to the whole country without dead ends.

In terms of network speed, take the test of downloading email 10M attachment as an example, and download it 5 times with 163, QQ and Sina email respectively, and all of 15 times are downloaded within 1 minute, and the shortest time is only 30 seconds. Fujian Unicom has also carried out a number of interactive activities. Taking "Perfect 4G Beauty Shooting 10 second blockbuster" as an example, it attracted nearly 40 million netizens' attention within 30 days, and more than 30,000 people participated in the discussion of # Quick Select Wo4G # topic. After experiencing the peak speed of 150Mbps, the netizens in Fuzhou even made a remark on the Internet that "Unicom's 4G is coming, and it's exciting".

In addition, Fujian Unicom can enjoy the 4G network in most areas as long as it upgrades its software and expands its base stations. And launched a free combination package as low as 8 yuan. In the integrated package of 4G/3G, 76 yuan = 1GB+500 minutes, which lowered the threshold of 4G. At the same time, Fujian Unicom won the title of "20 13 Customer Satisfaction Enterprise in Communication Industry" last year. This year, Fujian Unicom launched the "quick service". Users can solve most problems immediately through 100 10 customer service, and all problems can be answered within two hours. At the same time, it also launched a handheld business hall with 24-hour service.

In addition to the above cities, seven cities including Xi, Changsha, Hangzhou, Chongqing, Shenyang, Harbin, Fuzhou and Shijiazhuang have also started FDD-LTE construction in an all-round way. After the successful commercial trial in the above-mentioned 16 cities, I believe that China Unicom is not far from the domestic official commercial FDD-LTE4G network.
