WLAN optimization ideasWireless Local Area Network is optimizing WLAN network optimization2010-11 Guangdong Telecom Engineering In the network of large-scale application of WLAN, network optimization is an indispensable step. As a professional WLAN engineering service provider, it has comprehensive network optimization technology service capabilities to provide customers with guarantees in WLAN business and operation.Guangdong Telecom Engineering Contents1 2 3 4 5 6OverviewWLAN network optimization processProblems to be solved in WLAN network optimizationCampus network optimization solutionSocial hotspot optimization solutionGuangdong Telecom Engineering Overview▲ Optimization targetWireless signal coverage reaches more than 98% of the design standard, and the signal strength in the coverage area reaches more than -75dbm; The signal-to-noise ratio reaches more than 15; The PORTAL authentication success rate reaches more than 99%, and the billing success rate reaches more than 99%.▲Scene analysisAccording to the AP deployment method, it can be divided into: indoor direct deployment, indoor distributed deployment, and outdoor deployment. According to the deployment location of AC, it can be divided into: AC hotspot local deployment, AC centralized remote deployment. According to the network design method, it can be divided into: two-layer deployment and three-layer deployment. ▲ Optimization principles 1. 2. 3. 4. 5. Make full use of existing WLAN-related equipment. Do not change the physical structure of the existing WLAN network. Coverage is given priority. Reduce co-channel interference by adjusting AP-related parameters or physical location while ensuring coverage. Consider the balance between capacity and interference in places where users are relatively concentrated, such as conference rooms. Guangdong Telecommunications Engineering Contents 1 2 3 4 5 6 Overview WLAN network optimization process WLAN network priority issues to be solved Campus network optimization solution Social hotspot optimization solution Guangdong Telecommunications Engineering Network optimization process I. Organize and analyze system basic data Phase 1. Collect existing network wireless test data (including signal strength, signal-to-noise ratio, delay, packet loss rate, etc.). 2. Environmental testing, focusing on testing areas with unsatisfactory test data, analyzing AP location, antenna coverage, adjacent frequency and co-frequency interference. Preliminary grasp of the main problems in the deteriorated area. 3. Data network analysis, analyze network topology, VLAN division, wired transmission link status, etc.,...
