Wi-Fi 인터넷서비스 확장을 위한 HFC기반의 유무선 통합시스템 연구

Abstract

In this dissertation, we propose the implementation of an integrated wire and wireless systems based on HFC (Hybrid Fiber and Coaxial) networks for extending Wi-Fi(Wireless-Fidelity) Internet services. And the performance evaluation of the suggested integrated systems is also given. In order to implement the proposed systems, the function of the Smart-AP (Access Point) which is composed of the cable modem combined with local wireless AP is developed, and then we design the network configuration of the proposed integrated wire and wirvieless networks based on HFC networks for providing Wi-Fi Internet services in the environments of 2.4GHz (IEEE 802.11b/g/n) and 5.8GHz ( IEEE802.11a/n). Experimental results show the efficiency of the proposed scheme in the aspects of service speed performance and service area extension. Eventually we expect that the suggested sytem would contribute to satisfy user needs for various Wi-Fi Internet services
