错误：

子模块收音机：没有名为“Ieee80211ScalarRadioMedium”的模块类型发现实现了模块接口 inet.physicallayer.contract.packetlevel.IRadio（不在加载的NED中文件？），在 /Users/ashish/omnetpp-5.3/samples/inet/src/inet/linklayer/ieee80211/Ieee80211Nic.ned:77 -- 在模块 (omnetpp::cModule) clientserverWLAN.host1.wlan[0] (id=42) 中，在网络设置期间

请帮助建立无线主机到 AP 和服务器之间的通信

尝试运行 UDP 应用程序

【解决方案1】：

您应该通过替换来指定无线电频道的类型

radioMedium: <mediumType> like IRadioMedium

与

radioMedium: Ieee80211ScalarRadioMedium
