In this paper, we present an implementation schemes of the IEEE 802.11n standard on wireless mesh network using multi-channel multi-interface technology and study for experimental results in an outdoor mesh testbed. We analyze the features of the IEEE 802.11n such as channel bonding, MIMO, and its behavior in multi-hop environment. In addition, we define the considerations for optimized design of mesh routers using IEEE 802.11n, and propose implementation schemes that can satisfy design requirements. As a result, we show the design techniques of high-performance wireless backbone network. Furthermore, we have implemented the real mesh router on an embedded board, and performed several experiments in an outdoor testbed. From experimental results, we evaluate the performance of the IEEE 802.11n over wireless mesh network with multi-channel multi-interface technique.
