This paper introduces a wireless presentation system that allows PCs to be connected to multiple projectors using an IEEE 802.11b wireless LAN in order to transfer PC screen images to the projectors in real time. Compared with the current method which requires cable connections, this system allows the screen images of PCs located anywhere in the meeting room to be projected using multiple projectors, making it easy to change speakers. In addition, direct communication using the data link layer permits connections between PCs and projectors to be established with ease.
