摘　　要：根据我国现行的频谱规划,在行业专网中可用于无线宽带专网建设的唯一授权可以使用的连续频段为1 785~1 805 MHz。由于多数行业专网承载业务和安全生产直接相关,有必要对该频段运行的无线运行环境进行分析。根据3GPP规划,该频段与Band3 FDD-LTE使用频段相邻,需要分析Band3频段对1.8 GHz TDD-LTE专网是否形成干扰。基于目前国家已经颁布的相关频率政策和型号核准要求对基站间干扰情况进行分析,并对相关型号核准文件提出建议。According to current spectrum regulation, band 1 785-1 805 MHz is the only authorized wireless broad- band spectrum. For most industry private network bearer business is directly related to safety production, it is neces- sary to analyze the running environment of the wireless spectrum operation. According to the planning of the 3GPP band and Band3 FDD-LTE band adjacent, it is necessary to analyze whether the Band3 frequency band interferes with the 1.8 GHz TDD-LTE private network. Based on the relevant frequency policies and model approval issued by the current state, the interference between the base stations was analyzed and suggestions for the relevant model ap- proval documents were made.
