摘要：

结合智能电网配用电应用的通信需求，基于LTE核心技术定制开发的LTE 230系统使用230 MHz频段，与高频段相比，信号传播距离远、绕射能力强，大幅提升了系统的覆盖能力。该系统在密集城区的覆盖能力可达4 km以上。基于Okumuram-Hata模型，采用精确的链路预算，给出了LTE 230系统的理论覆盖能力。同时，根据深圳供电局在深圳福田区建设的LTE 230试验网的测试结果，验证了LTE 230系统在密集城区环境的实际覆盖能力与理论值相符。

Abstract:

Combination with the smart grid communication needs, LTE 230 system is customized development based on the LTE core technology and uses 230 MHz frequency band. Compared with the high frequency, the signal of 230 MHz frequency spread far and has strong diffraction capability. It greatly improves the covering capacity of system. The covering capacity of the system can reach more than 4 km in the dense urban area. Based on the Okumuram-Hata model and the precise link budget, the theory covering capacity of LTE 230 system was given. At the same time, according to the testing results of the LTE 230 experimental network which Shenzhen Power Supply Bureau has built in Shenzhen Futian district, the LTE 230 system is verified that the actual coverage ability correspond with the theoretical value in dense urban environment.

Key words: smart grid, wireless private network, LTE 230 system, wide coverage
