BreadCrumb® LX4

Portable Wireless Mesh Network Node
APPLICATIONS
►MINING

For open pit and underground mines, BreadCrumb devices form a resilient network for
mine monitoring and control. Typical applications include Miner Tracking, Emergency Rescue, Voice communications (VoIP), Dispatch,
Routing, Health Monitoring and Video.

►MILITARY

With battery power, rugged enclosures, singleswitch operation and robust security, BreadCrumb devices are perfect for military applications such as Perimeter Security, Sensor Data
Collection, Video Surveillance, Convoy Security, RFID Tracking and more. Depending on
BreadCrumb model, security options range
from WEP, WPA2, SecNet 54® to FIPS 140-2.

►FIRST RESPONDERS

BreadCrumb devices form an instant secure
network for emergency response, disaster relief, RFID tagging, voice communications
(VoIP), PDAs, laptops, video and sensor applications. The included Ethernet port can provide Internet access through satellite or microwave links.

InstaMesh®
InstaMesh ® is an advanced protocol developed
by Rajant that allows for continuous and instantaneous routing of wireless and wired connections. It enables complete network mobility,
robust fault tolerance, high throughput and low
latency, with zero maintenance and administration. The BreadCrumbs combine InstaMesh ®
with support for standards in wireless access,
security, network monitoring, QoS and much
more

Rajant BreadCrumb® LX4
The Rajant BreadCrumb LX4 is a
rugged, multi-radio, wireless
transceiver that forms a mesh
network when used in conjunction
with other BreadCrumb devices.
This portable, wireless mesh
network node contains between
two and four radios, and supports open-standard IEEE 802.11a/b/g
protocols to enable data, voice, and video applications. This full
featured device can operate in extreme conditions and has several
mounting options.

Mesh-to-mesh authentication provides secure networking.
Multiple simultaneous bridge-mode links to the same Ethernet
network through Automatic Protocol Tunneling (APT) feature.

BC|Commander® Management Tool

In this diagram, the Rajant mesh network
adapts to the changes caused by the movement of Node E. New links are established in
real-time keeping the network available, intact
and secure.
Because Rajant uses primarily Layer-2 and does
not use a root node or LAN Controller, mobility and
bandwidth are maximized. Multiple gateways and
secure mesh-to-mesh authentication are also supported.

BC|Commander and BC|Commander Enterprise
software tools are used to configure, manage, and
monitor your Rajant network.
