BreadCrumb® ME4

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, single-switch
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.

►F I R S T R E S P O N D E R S
BreadCrumb devices form an instant secure network
for emergency response, disaster relief, RFID tagging, voice communications (VoIP), smartphones,
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® ME4
The Rajant BreadCrumb ME4 is a rugged,
wireless transceiver that forms a mesh network
when used in conjunction with other
BreadCrumb devices. This portable, wireless
mesh network node contains two radios, and
supports open-standard IEEE 802.11a/b/g/n
protocols to enable data, voice, and video
applications. This full featured device can
operate in extreme conditions and has several
mounting options.

Multiple radio configurations support
comprehensive applications and deployment environments—
900 MHz, 2.4 GHz, 4.9 GHz, 5 GHz and others…
Supports NSA Suite B cryptography algorithms for data and
MAC address encryption and per-hop, per-packet authentication
Lightweight and portable.
Rugged and environmentally sealed.
Offers high-bandwidth for data, voice, and video applications.
Ability to scale to hundreds of mobile, high-bandwidth nodes.
Runs InstaMesh®, so the network quickly adapts to moving
network elements.
Open-system IEEE 802.11a/b/g/n standards for compatibility
with millions of commercial off-the-shelf (COTS) client devices
such as laptops, smartphones, IP cameras, sensors, VoIP
phones and other IP devices.
Self-configuring operation for fast and easy deployments.
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 per-hop, per-packet authentication are also
supported.

The BC|Commander software tool is used to
configure, manage, and monitor your Rajant network.
