802.11（WiFi）是一种成熟的网络通信协议，在民用基础设施中具有广泛的适用性。本文介绍了研究，探讨了802.11网络的设计增强，以支持在灾难环境中的数据通信。这些努力的重点是建立网络基础设施，以支持都市医疗反应系统单位和联邦赞助的区域小组的行动，这些单位和小组应对使用化学、生物、核或放射性武器的恐怖袭击或危险材料泄漏造成的大规模伤亡事件。在本文中，我们描述了一种先进的基于WiFi的网络架构，旨在满足MMRS业务的需求。该架构将用于接入点之间的对等多跳连接的无线分发系统与用于到互联网的稳健连接的对多个蜂窝回程的灵活和共享接入相结合。该架构提供了一个高带宽的数据通信基础设施，可以渗透到建筑物和结构，同时也支持商业现成的最终用户设备，如PDA。它是自我配置的，并且在基础设施的一部分丢失的情况下自我修复。原型装置的测试正在进行中。
802.11 (WiFi) is a well established network communications protocol that has wide applicability in civil infrastructure. This paper describes research that explores the design of 802.11 networks enhanced to support data communications in disaster environments. The focus of these efforts is to create network infrastructure to support operations by Metropolitan Medical Response System (MMRS) units and Federally-sponsored regional teams that respond to mass casualty events caused by a terrorist attack with chemical, biological, nuclear or radiological weapons or by a hazardous materials spill. In this paper, we describe an advanced WiFi-based network architecture designed to meet the needs of MMRS operations. This architecture combines a Wireless Distribution Systems for peer-to-peer multihop connectivity between access points with flexible and shared access to multiple cellular backhauls for robust connectivity to the Internet. The architecture offers a high bandwidth data communications infrastructure that can penetrate into buildings and structures while also supporting commercial off-the-shelf end-user equipment such as PDAs. It is self-configuring and is self-healing in the event of a loss of a portion of the infrastructure. Testing of prototype units is ongoing.
