China Unicom opens 3G new round of expansion

Author: Huanghai "The continuous construction of 3G Boutique network, improve the breadth of 2G network coverage, and increase maintenance and optimization efforts to significantly improve the quality of the network."　　Yimin, general manager of China Unicom, said in his work report in mid-July that wireless network construction is one of the key tasks of China Unicom in the second half of the year. At present, China Unicom has made great achievements in wireless network, which has strongly supported the rapid development of new business of China Unicom and the continuous improvement of user experience under the whole business background. As you can see, in the 3G evolution, China Unicom has successfully implemented HSPA (high-speed packet access evolution) upgrade in Guangdong, laying the technical foundation for the rest of the urban WCDMA network upgrade. In the area of wireless network coverage, it is reported that China Unicom is currently carrying out a new round of 3G network expansion, the plan will cover all traffic routes and key tourist attractions, and cover all townships in developed areas.　　In addition, China Unicom is also carrying out WLAN collection, which will vigorously promote the construction of wireless cities.　　HSPA, WLAN, Femto full bloom in the 3G evolution, such as wireless network development, Unicom in the forefront. August 6, China unicom Guangdong Branch (hereinafter referred to as "Guangdong Unicom") in Guangzhou and Zhuhai show the domestic most advanced 3G network technology--hspa+. Based on the HSPA of Guangzhou Wcdma/hspa Current network, this paper realizes 40mbit/s, which is very close to the theoretical downward rate. This rate is more than twice times the current net speed of Guangzhou Wcdma/hspa, in the global also belong to the leading level.　　Earlier, Yimin also said that China Unicom in Beijing, Shanghai and other sites are also conducting HSPA pilot. According to some manufacturers, China Unicom has recently launched a nationwide wireless city bidding, is expected to carry out large-scale equipment bidding around October. "At present, China Unicom's wireless city bidding has been initiated by the group to formulate a unified bid for the distribution of documents, according to technical standards and business standards of the comprehensive factors."　　The manufacturer points out that China Unicom's bidding equipment is expected to be about 200,000 units, of which AP accounted for Two-thirds, while AC accounted for One-third. For Femtocell (hereinafter referred to as FEMTO), China Unicom is the earliest to introduce femto operators, has been in Hebei and other 10 provinces and cities to launch trial commercial service stations. "China Unicom in two stages to promote FEMTO: The first phase of the 2010, the main content is to use femto equipment to solve the early 3G construction of indoor coverage, family data business preferences; The second stage, after 2011, with the maturity of femto related technologies and standards, Unicom will use Femto to achieve the integration of FMC business, to obtain value-added benefits.　　Yang Xiaochun, director of China Unicom Market integration operations, said in the 2010 China Femto Summit Forum. The second half of the 3G network continued to expand China Unicom Network Ministry of Construction Wangchangling told reporters that China Unicom is carrying out a new round of WCDMA network expansion, plans to cover more towns and highways, railways and other transport lines, some provinces and cities have first proposed to create a boutique 3G network.　　This expansion does not take the system equipment tendering method. By the end of 2009, China Unicom WCDMA Network built 97,000 base stations, wireless network coverage of the country's 335 urban areas and 54% of the county, and now covers all county.　　The expansion will further expand the network coverage and improve the quality of the network. In the construction requirements, China Unicom proposed that in the WCDMA coverage area, the requirements of cs64kbit/s business can be continuously covered, the full network synchronization into the HSDPA/HSUPA,WCDMA and GPRS network complementary, mutual support, which,　　The High speed data service and voice service are carried by WCDMA network, and the GPRS network carries low speed data service and voice service. At present, Unicom has developed expansion plans in various regions. For example, Beijing Unicom to the WCDMA core network expansion, wireless network 1482 new base station, expansion of the dual-carrier base station 400, expansion of three carrier base station 200.　　962 sets of new indoor distribution system and related supporting, installation indoor cover 3G source 1048 sets, independent Rru 690, to 2010 years of Four seasons, will be completed. Solution Huawei: The Singleran@broad solution is an upgraded version of Huawei's Singleran solution, a solution that enhances mobile broadband performance, which will drive the global mobile industry's transition from voice to data generation, achieving more than 500 times times of mobile broadband traffic growth over 10 years, and 95% The above cost per bit drops, and enhance the user experience, to ensure that operators calmly respond to the rapid development of mobile broadband business opportunities.　　Huawei's first Singleran solution in the industry has also been widely favored by operators and has been deployed on a network of more than 40 operators worldwide. Ericsson: Ericsson's RBS 6000, the main driver behind a large number of fast deliveries, is a multi-format energy-efficient base station that supports Gsm/edge, WCDMA/HSPA and LTE in a single cabinet. The RBS 6000 products include indoor, outdoor and master remote series. Compact design makes it less space to occupy, only 25% of the previous generation, while capacity increased 10 times times, the RBS 6000 series power consumption has decreased by 20% to 65% compared to previous Ericsson wireless base stations, and is by far the most energy efficient and very well performing base station in the industry.
