Accessible communications are becoming an important part of most peoples everyday life. Both business and private users increasingly expect to be able to contact people and get information from any location, not just while at the office or workplace. The incredible success of the mobile phone has further increased the expectations of users in this area. To cater for this demand, a new generation of connectivity possibilities based on wireless local area networks (LAN's) named Wi-Fi is being established.Wi-Fi, or Wireless Fidelity allows you to connect to the Internet from your chair at home, a bed in a hotel room or a conference room at work without wires. Wi-Fi is a wireless technology like a cell phone. Wi-Fi enabled computers send and receive data indoors and out; anywhere within the range of a base station. It's several times faster than the fastest cable modem connection and is rapidly being installed in many locations, such as corporate facilities, in airports, hotels, coffee shops and other public areas equipped with Wi-Fi access.Wi-Fi is based upon an Industry standard technology known as the IEEE 802. This is relatively easy and inexpensive to implement and is being widely deployed in many public areas and commercial settings. It has been estimated that over 30 million Wi-Fi cards would ship in 2004 illustrating the impressive rate of growth of this technology. Wi-Fi transmissions can thus be viewed as a future, widely available local area signal. Apart from the communications aspect, these signals have the potential to be used for other purposes. Particularly of interest is the possibility of detecting objects and people using the principles of Radar. In conventional Radar pulses are transmitted and received by the same equipment. In its simplest form this allows the user to detect whether a target is present and how far away from the radar it is by the time delay before the pulse is returned. IF the transmitter and receiver are separated then the processing is slightly more complex but the basic principles still apply.Using Wi-Fi transmissions for this purpose could lead to the development of a surveillance capability from a ubiquitous and accessible source. All the transmissions would already be available and a relatively simple receiver systems could be designed to carry out this task. Such a system could have be used for many purposes including improving internal and external security and identification and tracking of goods and people.There are, of course, many problems to be overcome in applying these realtively simple principles in a real world situation. This short study is inended to demonstrate the feasibility of the basic principle and investigate also investigate the newer 802.15 and 802.16 technologies. This research will aim to demonstrate that a surveillance system based on wireless LAN's is a viable technogy and outline a plan for full scale research and development.

无线通信正成为大多数人日常生活的重要组成部分。企业和私人用户都越来越希望能够从任何位置联系人并获取信息，而不仅仅是在办公室或工作场所。移动的手机取得的令人难以置信的成功进一步提高了用户在这一领域的期望。为了满足这一需求，基于无线局域网（LAN's）的新一代连接可能性正在建立，称为Wi-Fi。Wi-Fi或无线保真（Wireless Fidelity）允许您从家中的椅子、酒店房间的床或工作会议室连接到互联网，而无需电线。Wi-Fi是一种类似手机的无线技术。启用Wi-Fi的计算机可在室内和室外发送和接收数据;在基站范围内的任何地方。它的速度比最快的电缆调制解调器连接快几倍，并迅速安装在许多地方，如公司设施，机场，酒店，咖啡店和其他公共场所配备Wi-Fi接入。Wi-Fi是基于一个行业标准技术，称为IEEE 802.这是相对容易和廉价的实施，并广泛部署在许多公共领域和商业环境。据估计，2004年将有3000多万张Wi-Fi卡发货，这说明这项技术的增长速度令人印象深刻。因此，Wi-Fi传输可以被视为未来广泛可用的局域信号。除了通信方面，这些信号还有可能用于其他目的。特别令人感兴趣的是利用雷达原理探测物体和人的可能性。在常规雷达中，脉冲由同一设备发射和接收。在其最简单的形式中，这允许用户通过脉冲返回之前的时间延迟来检测目标是否存在以及它离雷达有多远。如果发射器和接收器是分开的，那么处理过程会稍微复杂一些，但基本原理仍然适用。为此目的使用Wi-Fi传输可能会导致从无处不在和可访问的源开发监视能力。所有的传输都已经可用，可以设计一个相对简单的接收器系统来执行这项任务。这种系统本可用于许多目的，包括改善内部和外部安全以及货物和人员的识别和跟踪。当然，在真实的世界局势中应用这些相对简单的原则时，有许多问题需要克服。本文旨在论证基本原理的可行性，并对802.15和802.16新技术进行研究。本研究的目的是证明基于无线局域网的监控系统是一种可行的技术，并概述了全面的研究和开发计划。
