摘 要
无线局域网（Wireless Local Area Network，即WLAN）是指以无线信道作为传输媒介的计算机局域网。它是有线网方式的重要补充和延伸。通过无线网络的移动性结合现代信息技术，无线局域网还可以实现无线Check-in（登记）功能，移动点餐功能，无线VoIP（IP电话）等功能。无线局域网采用射频技术，取代旧式的双绞线所构成的局域网络，将计算机设备互联起来。客户可通过笔记本电脑、PDA（Personal Digital Assistant，即掌上电脑）等终端以WLAN随时随地接入互联网和企业网，获取信息、娱乐或进行办公。
本文主要介绍某宾馆WLAN室内信号覆盖系统工程设计。文中第一部分对WLAN的演进发展与应用前景进行了介绍。第二部分是对WLAN的基础知识进行了介绍，包括WLAN的基本原理、硬件设备要求等内容。第三部分介绍了WLAN的规划方法。第四部分着重对宾馆WLAN的覆盖方式、频点规划、网络结构、等做了详细阐述，尤其对整个流程的优化以及覆盖、容量、信道三种优化做了解释。在论文最后对本文所做的研究进行了总结。

WLAN indoor coverage systems engineering design of a hotel
ABSTRACT
Wireless LAN (Wireless Local Area Network, or WLAN) is a kind of computer network which refers to the wireless channel as a transmission medium. It is an important complement and extension of the cable network. Combining modern information technology with the mobility of the wireless network, wireless LAN can realize Wireless Check-in function, mobile ordering functions, Wireless VoIP functionality. Wireless local area network uses radio frequency technology to connect computer equipment for replacing the old twisted pair local area network. Customers access to the Internet and corporate networks, access to information, entertainment or office through the terminal of notebook computers, PDAs and other WLAN anytime, anywhere.
This article introduces a hotel WLAN indoor coverage systems engineering. The first part introduces the WLAN evolution of the development and application prospects. The second part describes the basics of WLAN, including the basic principle and the WLAN hardware requirements. The third section describes the planning of WLAN. Part four focuses on coverage of the hotel WLAN frequency planning, network architecture, particularly explaining the optimization of entire process and the coverage、capacity、channel. Finally, there is a summary of the research done in this article.
