我正在尝试创建一个具有至少三种不同技术的网络，包括（WiFi、蓝牙、LORA 和/或 5G）。我的问题是：
1-是否可以将它们放在同一个网络中？2-如果可能，如何实现具有两个以上接口（NIC）的节点（无线主机）？
我正在开发 OMNET++ 6 pre 11 作为具有 INET 框架和 SIMU5g、FLORA 的模拟器。
从下面的示例场景中，WiFi 和 LORA 技术叠加在一起，如图所示：
当我运行模拟器时，我收到以下错误消息：
check_and_cast(): 网络初始化期间，无法将 'inet::physicallayer::IListening*' 类型转换为 'constflora::LoRaBandListening *' -- 在模块 (flora::LoRaMedium) My_Net.LoRaMedium (id=9) 中
Net代码和ini代码（配置代码）呈现：
