3.1 hubei mobile wireless network 4g phase i project

☆ construction unit: china mobile communications group corporation hubei co., ltd

☆ investment amount: 175.4 million yuan

☆ duration: september 2013 -- february 2015

☆ main work content: the project deployed 4g network construction in 4 prefectures and cities of xiangyang, shiyan, suizhou and enshi in hubei province, with a total of 3842 new base stations, including 3552 new acer stations and 290 new sub-source base stations; a total of 11,224 new carrier frequencies were added, including 10,656 new carrier frequencies for acer station and 568 new carrier frequencies for room sub-source.

nurture social benefits: this project formally opened in hubei mobile in the age of 4 g, wireless network bandwidth and rate greatly ascend, can reach several dozen times the td-scdma 3 g era, have made it possible to high-speed internet access, the change in the information industry and other related industries and development, and further affect everyone's life, has a huge social and economic benefits.

☆ highlights in technology and management: 4g td-lte technology is adopted in technology, including a large number of chinese patents, led by china, and has received extensive international support, becoming an international standard. in terms of management, the use of the project management platform has significantly improved the management level and efficiency of the project construction, and created a record of completing the installation of up to 103 wireless base stations in one day in xiangyang. give full play to the project construction management work in the improvement of progress, quality, cost, compliance, safety and other engineering five elements of management.

3.2 in 2017, leshan 800m lte wireless network base station construction project in emei xinlian village, etc

☆ construction unit: leshan branch of china telecom corporation limited

☆ investment amount: 15.517,600 yuan

☆ construction period: march 2017 - may 2017

☆ main work content: 800m lte network construction is carried out in 10 counties and urban areas of leshan city, with a total of 235 stations in scale, including 126 stations in layuan and 109 stations in sinking; bbu plug-in board upgrade 61 points, a total of 101 board cards; new bbu102 units; install rru505; the antenna is 635.

☆ social benefits: after the completion and operation of this project, the rural area has realized leapfrog development from scratch to excellent. 4g network coverage effect is obvious, the experience is better. now, in leshan rural areas can also use the 4g network for network browsing, watching high-definition video and other services, the network speed test is more than 30m. the whole lte 800m network replanting not only solves the 4g network coverage problem for china telecom, but also forms a differentiated advantage with china mobile in 4g network coverage.

being is the window on technology and management: to use the 800 m (equipment technology, the rural side adjustment out 78, 119, 160 and 201, a total of four frequency points, according to the boundary coordination principle, choose at least two spare frequency points in the rural side deployment of lte, 1.4 mhz bandwidth and city side of lte bandwidth and center frequency keeps consistent, avoid the cdma 78, 201 frequency points and rural city 5 mhz bandwidth problem of same frequency interference in a lte, form a smooth transition. using the enterprise project management platform, the project plan, construction preparation, technical disclosure, site construction, process inspection, power-on test, system joint adjustment, completion and inspection, trial operation, completion and acceptance, cutoff into the network, production and maintenance, final accounting audit life cycle closed-loop management is realized.
