| Summary: | 碩士 === 國立中央大學 === 通訊工程學系 === 101 === As the progress of wireless communications, IEEE 802.11 is no exception. IEEE
（Institute of Electrical and Electronics Engineers）formulates new specification
IEEE802.11AC in the past two years. 2.4GHz（ISM） of IEEE802.11n is almost
saturated，and 802.11AC operates at 5GHz. In contrast, the signal has a smaller
chance having interference. Nowadays, 802.11 AP (Access Point) is one of our
necessary tools. It has three reasons：1.The cost is not expensive and everyone could
afford the AP router. 2. Setting up is not complicated. 3. The throughput is good and
the AP router can supply WLAN to users. Based on the above advantages，most
organizations could deploy lots of AP router for local users. Everyone usually ignores
channel interference problems. Sometimes, AP routers are interfered by other
company’s AP or set up AP by their own selves, which causes weak WLAN signal or
bad throughput. In this thesis，we use the genetic algorithm for solving the coverage
problem in the deployment of AP routers. We calculate SINRs among APs for the
radiation of AP routers. The AP router‘s channels are staggered. The simulation is
conducted to verify the efficacy of the proposed method.
