Abstract: This paper does a research in the technology of handover and routing. It analyzes the problems of losing packets in rapid handover and inaccurate routing. It also proposes dual-channel asynchronous switching scheme and Optimized Link State Routing(OLSR) scheme based on bandwidth. It does some field test for the feasibility of the proposal. Results show that the wireless communication system using above-mentioned scheme has a very good performance in some aspect such as bandwidth and packet loss rate, and it sets a good example for the next project implementation.
