随着802.11 a/B/g在市场上的巨大成功，WiMAX、UWB等新的无线连接技术也开始进入人们的生活。射频收发器（无线电）的成本越来越低，使我们可以考虑在同一设备中使用两个或更多无线电。无线Mesh网络扩展了无线网络的覆盖范围，通过多跳重传在传输对之间转发数据包，使无线服务无处不在。鉴于此，我们认为，无线系统使用异构多个无线电在一个协作的方式显着提高系统的性能和功能，在传统的单无线电无线网状系统。设计了异构多射频无线Mesh网络的系统模型，提出了异构多射频无线Mesh网络的新的研究课题和挑战，包括异构多射频Mesh网络客户端的切换模型，异构多射频Mesh网络的信息获取、共享和基于分布的管理与控制。我们还提出了设计无线电度量和应用需求为基础的路由算法的指导方针。新的观点支持异构多无线电平台为我们未来的无线系统提供了显着的好处。
As 802.11a/b/g achieves great success in market, WiMAX, UWB and other new wireless connection techniques are moving into our daily life. The lower and lower cost of RF transceivers (radios) allows us to consider using two or more radios in the same device. Wireless mesh network extends the coverage of wireless network, which forwards packets between transmission pair by multiple hop retransmissions to make wireless service everywhere. Given this, we argue the wireless systems using heterogeneous multiple radios in a collaborative manner dramatically to improve the system performance and functionality over the traditional single radio wireless mesh systems. We design the system model of wireless mesh network with heterogeneous multiple radios, and outline new research topics as well as some challenges under it including handoff model for mesh client with heterogeneous multiple radios, information grasping, sharing and distribution based management and control for heterogeneous multiple radio mesh network. We also present the guidelines for designing radios metric and application requirement based routing algorithms. The new views supports that a heterogeneous multiple radio platform offers significant benefits for our future wireless systems.
