2.0 INTRODUCTION
Rajant Corporation's (www.rajant.com) ME BreadCrumb integrates Ethernet and wireless
IEEE 802.11b/g connectivity with mesh networking protocols. The network is mobile, self-
integrating, self-meshing, self-healing, full-duplex and secure. An internal Li Ion
rechargeable standby battery can power the unit when external power is unavailable. The
focus is on flexibility, adaptability, and simplicity.
The BC (BreadCrumb) is intended for rapid deployment of a broadband wireless network
into a situation or ‘hot zone’.
The BreadCrumb wireless network components utilize the IEEE 802.11b/g wireless
networking standard to form a wireless mesh network. 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).
NOTE: This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own
expense.
2.1 WHAT IS A BREADCRUMB?
A Bread Crumb device is an 802.11b (Wi-Fi) Access Point specifically designed for the
following scenarios:
2.1.1 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).
2.1.2 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).
2.1.3 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.).
2.1.4 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).
