【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]:Combined with the communication requirements of smart grid distribution and power applications, the LTE 230 system, which is custom-developed based on LTE core technology, uses 230 MHz band. Compared with the high frequency band, the signal propagation distance is long, the diffraction ability is strong, and the coverage ability of the system is greatly improved.The coverage of the system in dense urban areas can reach more than 4 km.Based on Okumuram-Hata model, the theoretical coverage ability of LTE 230 system is given by using accurate link budget.At the same time, according to the test results of LTE 230 test network constructed by Shenzhen Power supply Bureau in Shenzhen Futian District, it is verified that the actual coverage capacity of LTE 230 system in dense urban area is in accordance with the theoretical value.
