In the paper, a conception of wireless LAN based on the technology of optical diffusion communication is presented. By analyzing the system's structure and each part of the function components, the paper illustrates in detail all kinds of communication theories and protocols that are fundamental for the system's operation. Especially, the paper makes a deep research on some crucial technologies by which a new kind of wireless LAN becomes hopeful, competitive and above all, practical.
    To fulfill the communication industry's ultimate end (5W), it is necessary to transit the communication network from wire-connected to wireless-connected, immobility to mobility and single service function to multi-service functions. With the support of computer communication technologies and wireless communication technologies, Wireless Local Area Network (WLAN) is brought to life and is recommended widely as an important component of Personal Communication System (PCS). Following ATM and 1000M Ethernet network, WLAN is a hit point in the communication research field now, and is thought highly as the future of communication network. By adopting the optical diffusion communication technology and PPM coding theory, the paper presents a new method to build a Wireless LAN that is fit for broad communication with so many advantages, such as high security, huge capacity and freeing from frequency limitation.
    The paper contains all kinds of knowledge related to the system, including Maxwell electromagnetic theory, pattern of optical radiation in space, channel model of atmosphere communication, computer communication protocols, Wireless LAN communication protocols, Medium Access Control protocol, Carrier Sense Multiple Access/Collision
    
    
    
    Detection protocol, Manchester Coding theory, Pulse Position Modulation Coding theory and so on. The main originalities and latest technologies used in the operation of the system are as following: 1.Connecting computers through optical devices in a LAN wirelessly. high speedily and cheaply by using the technology of optical radiation communication. 2.Applying Manchester Coding theory to meet the end of collision detection and codes judgment effectively. 3.Using Pulse Position Modulation (PPM) coding theory that is invented especially for optical communication in the air to ameliorate the system's performance by improving the system's character of PE. 4.Taking good advantages of the fledged LAN communication protocols and technologies to achieve a new method that has a high rate of capability to cost in building a wireless LAN.
    The paper has done some analysis and research on technologies about Wireless LAN and has made some achievement on it. Wireless LAN based on the technology of optical diffusion communication is very practical and will be competitive in market application. It is a useful supplement to the LAN now and will be more and more important in the future in communication network.
