C114 News, August 6 morning news (Zhang YueHong) with the domestic TD-LTE expand the depth of the work of the large-scale trial network, as one of the Ministry of Industry to determine the first six TD-LTE pilot cities, Guangzhou TD- LTE network construction is carried out in an orderly manner as scheduled. In response to the Ministry of Industry has proposed “to speed up the expansion of the pace of scale test, extended test to participate in the city and its network size” guidelines to better meet the needs of users to enjoy data services, Guangzhou Mobile intends on the basis of the original plans to build scale to further expand the scale of construction of the TD-LTE test network.

scale trial network size

learned from the current 13 cities reported, Guangzhou TD-LTE network, the latest reported scale of about 3100 sites to 3700 sites from the initial planning, total construction in 2012 in 13 cities 18.5% of the 20000 scale site plan to be completed by the end of 2012 the network construction.

Guangdong Mobile (microblogging) launched in March this year, the TD-LTE trial network construction, network contractor for the ZTE, the test network using the frequency bands in accordance with China Mobile (microblogging) on ​​TD-LTE unified planning, basic network coverage smooth upgrade of the F band, speed up the progress of the network construction. C114 It is understood that the end of July, ZTE has completed nearly 1,300 site equipment installation within the coverage area, accounting for 35% of the scale of construction.

construction and optimization at the same time speed

C114 previous reports, ZTE To this end, Guangzhou Mobile’s TD-LTE network introduction of its C-RAN solution, the overall network architecture using a combination of macro and micro-based three-dimensional networking solutions to the Small Cell, for the future implementation of CoMP the collaborative program and eICIC of anti-jamming programs do a good job to prepare the network structure, can maximize the interference avoidance algorithm performance, improve the average user throughput and edge throughput, ensuring that users get a good 4G business experience.

from 3G to 4G and the smooth evolution for the base station of the existing network based on a unified platform technology, ZTE through a simple software configuration, while meeting to support the TD-SCDMA, TD-LTE singlemode and TD-SCDMA/TD-LTE of common-mode requirements in order to achieve the smooth evolution of TD-SCDMA to TD-LTE.

based on the SDR platform, BBU, the upgrade process, the only increase in the TD-LTE baseband board, software upgrades can be to meet TD-SCDMA/TD-LTE common-mode applications. RRU equipment of the FA band TD-SCDMA network TD-SCDMA/TD-LTE dual-mode system, so only a software upgrade hardware without any changes. This mode of building a network, to ensure that the network construction progress, saving the cost of network construction and construction period.

rapid deployment in the network at the same time, the TD-LTE network to enhance the quality work put on the agenda. University City area to complete the entire network coverage, ZTE investigation by site failure, the relationship between optimal allocation of adjacent areas, pilot pollution optimization, cross-district interference control, the back lobe interference of the antenna sidelobe control, pinhole coverage optimization, switching parameter optimization, power control optimization, the PDCCH parameter optimization, optimization means to raise the overall network indicators of Guangzhou University City, SINR <0dB probability of only 3.11 percent, the district average throughput of the entire network to 28Mbps, the follow-up on this basis to further optimize reach 30M .

terminal mature with large-scale application conditions

Guangzhou Mobile launched TD-LTE user experience, this year’s 5.17 Telecommunication Day to provide users with experience in two ways: the data card and CPE terminal. From Guangzhou field pilot work, ZTE to provide a single ZIFI products to meet more than 20 STA terminal access TD-LTE network, the average single-user access speed to reach 20M has been initially with the scale of application conditions. Guangzhou Mobile plans such end-use applications to be gradually extended to the bus, subway, high-speed rail transport sector.

the ZIFI

ZTE to provide terminal, while support of TD-SCDMA, TD-LTE, which is equivalent to CPE + WiFi hotspots, volume ratio of the base station is small, slightly larger than the CPE. It is reported that Guangdong Mobile, government and enterprise department in the government-enterprise project into the ZIFI application, consider the CBD, commercial outlets, residential areas, government buildings, high-end residential, professional market scenario by deployment ZIFI terminal to achieve the rapid introduction of mobile “global eye “business.

commercial LTE products including card, CPE, The MiFi, ZiFi, flat, such as mobile phones, ZTE recently announced the end of this year launched TD-LTE smartphone.

According to the latest planning, the Guangzhou TD-LTE network will become the largest pilot cities in the country’s TD-LTE network. Guangzhou City, focused almost entirely on a cloth net in all regions of the scene, there are a large number of villages and other existing skyscrapers, Guangzhou, there are still PHS users, China Mobile to expand TD-LTE network construction scale, Guangzhou, can more scene, a deep understanding of a wider scope, such as TD-LTE coverage, capacity, interference with core issues such as better validation of the commercial capacity of this network.
