摘　　要：针对无线终端中LTE Band40模块与WLAN2.4 GHz模块相互干扰的情况,给出了干扰分析模型。分析了WLAN2.4 GHz模块发射信号干扰LTE Band40模块接收特性和LTE Band40模块发射信号干扰WLAN2.4 GHz模块接收特性,给出了WLAN2.4 GHz模块与LTE Band40模块同时工作时相互干扰的结果,提出了LTE Band40模块发射信号干扰WLAN2.4 GHz模块接收明显大于WLAN2.4 GHz模块发射信号干扰LTE Band40模块接收的特性。在一个无线终端中不推荐同时使用LTE Band40的高频段和WLAN2.4 GHz的低频段。This paper analyzes the cause of the mutual interference between LTE Band40 radio module and WLAN radio module in wireless equipment. The analysis model of the mutual interference is given, as well as the analytic result and the experiment result of the mutual interference. This paper also presents that the receiving performance of LTE Band40 module becomes bad when WLAN 2.4 GHz module is transmitting maximum power signal,and the receiving performance of WLAN 2.4 GHz module becomes worse when LTE Band40 module is transmitting maximum power signal. Therefore the high frequency of LTE Band40 and the low frequency of WLAN 2.4 GHz are not recommended to use at the same time.
