1 Introduction
Rajant Corporation's (http://www.rajant.com) BreadCrumb LX/LX3 utilizes the IEEE 802.11a and
802.11g wireless networking standards to form a wireless mesh network. The network is mobile,
self-integrating, self-meshing, self-healing, full-duplex and secure. The focus is on flexibility,
adaptability, and simplicity.
The BreadCrumb Wireless Network (BCWN) is intended for rapid deployment of a broadband
wireless network into a situation or “hot zone.” The network can be deployed as a stand-alone
wireless network, or bridged to another network (such as the Internet) utilizing available reach-back
communication links (such as a DSL, cable, or satellite modem).
BreadCrumb LX/LX3 provides high bandwidth applications to stream video, audio as well as data
over large distances. The network traffic can be secured by using different security features offered
by the BCWN. This makes the network optimal for tactical deployments as well as emergency
response situations since it offers robustness, stability and ease of setup in mission critical activities.

1.1 What is a BreadCrumb?
A BreadCrumb is an IEEE 802.11 (Wi-Fi) and Ethernet compatible networking equipment which has
the capacity to connect to other BreadCrumbs or networking devices to form a BreadCrumb
network. A BreadCrumb is specifically designed for the following scenarios:
Temporary Wireless Networks
Networks that must be established quickly and with minimal effort for short-term use (e.g., a
network established to provide First Responder support at the site of a disaster).
Mobile Wireless Networks
Networks in which the network infrastructure itself is mobile, in addition to client devices (e.g., a
convoy viewing a video stream from a UAV).
Wireless Network Extension
Networks in which a wireless network must be quickly extended around or through obstacles that
block wireless communications (e.g., urban canyon networks, tunnels/caves, etc.)
Wired Network Extension
Networks in which two or more wired LANs at different locations must be connected wirelessly
(e.g., to securely connect combat service support computers with logistics bases)
Any Combination of the Above
