Network optimization is the abbreviation for "wireless network planning and optimization", which refers to various optimizations (including software, hardware, configuration, etc.) carried out on the basis of the completion of the communication network. By conducting traffic data analysis, on-site testing data collection, parameter analysis, hardware inspection, and other methods on the currently operating network, the reasons affecting network quality are identified. Through parameter modification, network structure adjustment, equipment configuration adjustment, and the adoption of certain technical measures (such as MRP planning methods), the high-quality operation of the system is ensured, and the existing network resources are optimized to achieve maximum benefits with the most economical investment.
In recent years, with the rapid growth of mobile users, their requirements for network communication quality have become increasingly high. Mobile operators have also carried out large-scale network optimization work with the goal of improving user perception, and proposed assessment standards for various key indicators. In 2003, with the expansion and construction of CDMA networks, China Unicom's construction concept for GSM had shifted from large-scale network construction to focusing on network optimization and potential tapping as the main goals to meet the rapid growth of users across the entire network. For GSM networks with extremely limited bandwidth, this actually puts forward stricter requirements for network optimization.
Bafang Telecom has been engaged in wireless network optimization evaluation business since February 2004. In March, it obtained the qualification of Huawei's after-sales service supplier, in June, it obtained the qualification of ZTE's after-sales service supplier, and in July, it obtained the certification of Huawei's and ZTE's wireless network optimization engineer. Its growth rate can be said to be very rapid. With the support of the company's diversified industries, Bafang has provided extensive resources, funds, and other powerful platform support for the engineering branch's network optimization products. At present, there are more than 150 engineers in the Bafang Engineering Branch, all of whom have a college degree or above, with half of them being intermediate and senior engineers. Their expertise covers wireless networks such as GSM (GPRS/EDGE), CDMA (1X/EV-DO), WCDMA, TD-SCDMA, etc. They have mastered the most cutting-edge technologies and have been committed to updating and developing them. At the same time, the company has equipped itself with excellent resources and adopted a project management system specifically designed for network optimization, implementing modular and virtualized management. It has a strict certification level evaluation and performance evaluation system to ensure customer service from both software and hardware aspects.
In June 2005, Bafang Engineering Branch took the lead in participating in Huawei's WCDMA trial network project at Zhejiang Mobile; In March 2006, led the completion of Samsung's CDMA experimental network project at the former Zhejiang Unicom; The first network relocation optimization project was completed in June 2007; In 2008, we undertook the Inner Mongolia Mobile Special Optimization Project, taking the first step towards nationwide expansion; In February 2009, undertook the first WCDMA new construction project for network planning and optimization; In July 2009, we undertook the first TD-SCDMA new construction project for network planning and optimization. It can be said that the product is gradually enriching and developing. After more than seven years of effort, Bafang Engineering Branch can now provide delivery of products including wireless, transmission, data communication, core network, broadband, switching access, etc. It can deliver all types of optimization services such as engineering network planning and optimization, third-party daily network optimization, centralized network optimization, testing and evaluation, which can basically cover the current types of wireless network optimization products and services.
The Bafang Engineering Branch will apply the mentorship system to project management, and all optimization personnel will be product engineering selection personnel, so that the advantages of technology can be continuously inherited, better serving our customers, maximizing the optimization of customer network resources, and helping customers obtain maximum benefits.
