A practical 4G sites planning scheme based on 3G multi-dimensional data analysis
When making 4G sites planning scheme, telecom operators prefer to reuse the existing 2G/3G site resources to reduce capital and operating expenditure. However, 4G is a typical co-frequency interference network with characteristics of hard handover and mode 3 interference. Thus, it is of great significance to identify the high-risk original 2G/3G sites which may cause interference problem. Based on the purpose, a novel 4G site reusability scheme considering both site attribute and coverage efficiency is proposed to improve 4G network planning accuracy. And we demonstrate the feasibility of the proposed model by quantitative correlation analysis. The prediction results indicate the proposed scheme can achieve great performance and help to improve 4G network quality effectively.
