摘要

现行射频规范限制470～510 MHz频段无线抄表系统不能适应电力网络新的通信速率和覆盖范围需求。如何调整相关射频规范，在保障邻频先用通信业务不受干扰的前提下，有效提升无线抄表系统的通信能力成为目前亟待解决的问题之一。针对该问题，首先分析国内450～566 MHz频段频谱划分情况。随后根据国家电网3种无线抄表系统的射频参数，通过确定性计算和射线追踪仿真的方法，研究所述无线抄表系统和邻频广播电视系统、CDMA450系统、铁路列调系统、FDD LTE系统之间的干扰共存情况。最后给出相关射频规范的修改建议。

Abstract

Current RF specification restrains the wireless meter reading system (WMRS) working in 470～510 MHz band.It is incapable of meeting new communication speed and coverage requirements of power network.Under the premise of ensuring that prior used communication systems in adjacent band work without interference

how to modify the related RF specification to improve communication ability of WMRS is one of the problems to be solved at present.Firstly

the domestic frequency spectrum allocation in 450～566 MHz band was analyzed.Then

based on RF parameters of 3 kinds of WMRS from State Grid and deterministic computation and ray tracing simulation method

the interference coexistence between the WMRS and adjacent communication systems

which including broadcast television system

CDMA450 system

railway train dispatching system and FDD-LTE system was studied.At last

some suggestions for revision of relevant RF specifications were obtained.
