Preface Purpose and Scope This manual provides information and guidance to all personnel who are involved with and use Rajant Corporation’s BreadCrumb® Wireless Network devices ("BreadCrumb® devices") in tactical situations. This manual begins with an introduction to the BreadCrumb Wireless Network and a brief overview of the various BreadCrumb device models available. This is followed by a guide to BCAdmin™, the management application used to configure BreadCrumb devices before or during a deplo

Chapter 1. Introduction Rajant Corporation’s (http://www.rajant.com) BreadCrumb Wireless Networks are portable, mobile, battery-powered, automatically-meshing, self-healing, full-duplex, secure, 802.11b access points. Their focus is on flexibility, adaptability, and simplicity. The BCWN (BreadCrumb Wireless Network) is intended for rapid deployment of a broadband wireless network into a situation or "hot zone." The BreadCrumb Wireless Network components utilize the 802.11b wireless networking sta

Chapter 1. Introduction Mobility through Meshing The key component to a BreadCrumb Wireless Network is a technique known as Meshing. While this is generally handled automatically by BreadCrumb devices, complex deployment scenarios require a basic understanding of how BreadCrumb devices establish and maintain a mesh. Mesh - A Definition A mesh is a collection of network devices (in our case, BreadCrumb devices), each of which is connected to one or more other BreadCrumb devices. Data can move betw

Chapter 1. Introduction Figure 1-1. Meshing Example 1 - Full Connectivity Example 2 Now suppose that you change the ESSID of BreadCrumb device C to "lonely". The network will adjust to this change, resulting in the following configuration: Note that BreadCrumb device C can no longer communicate with A or B, and vice versa. Figure 1-2. Meshing Example 2 - Different ESSIDs Prevent Meshing 3

Chapter 2. Upgrading to Version 8.4 This section is only necessary for BreadCrumb device/BCAdmin users of versions earlier than 8.4. If your entire BCWN is operating at version 8.4 or higher, you may safely skip this chapter. New Features • Fortress Technologies’ AES-256 encryption is enabled, allowing Fortress encryption to be used on existing BreadCrumb devices under Rajant’s new licensing terms with Fortress Technologies (http://www.fortresstech.com). Performance / Process Improvements • Mana

Chapter 2. Upgrading to Version 8.4 • Selection of a unique ESSID (network name) for the BreadCrumb network is recommended. A BreadCrumb device equipped with tri-color LED incorrectly indicates a meshed connection (GREEN) when in the presence of an 802.11b access point with the same ESSID. Installing / Upgrading BCAdmin 1. Install the latest JRE from http://www.java.com 2. Download version 8.4 of BCAdmin for Windows or Linux using the link provided by your Rajant Account Manager. 3.

Download the correct firmware zip archive for the board determined in the previous step, using the link provided by your Rajant Account Manager. 3. Create a new, empty folder and unzip the archive into it. 4. Copy the unzipped files (and only those files) onto an empty (no pre-existing files) ATA Flash Memory Card (of at least 16MB). The flash card may be directly purchased from http://www.magicram.com/flshcrd.htm 5. Proceed with

Chapter 2. Upgrading to Version 8.4 • Allow the BreadCrumb to operate FOR NO LESS THAN 5 MINUTES before rebooting or turning OFF. Important: After a flash update, you should ensure that at least one client device has the new BCAdmin installed, is "permitted" in the device’s ACL list, and is designated as an administrator. Important settings that were lost in the flash may be re-keyed, but do not reboot the BreadCrumb device until it has run for at least five minutes after its initial power-up after

Chapter 3. Models • On UAVs • In portable sensor packages Important: In a BCWN containing single-radio BreadCrumb devices, all BreadCrumb devices to which the single-radio BreadCrumb device communicates must have one radio on the same channel as the single-radio BreadCrumb device.

Its two radios and ethernet interface enable the full suite of BreadCrumb features (with the exception of long range and integrated video encoder), while its size allows it to be easily transported to and placed wherever necessary. BreadCrumb SEs have been rapidly deployed: • On rooftops • In trees or bushes • Hung from balloons

BreadCrumb XL - External Connector BreadCrumb XLV The BreadCrumb XLV is identical to the BreadCrumb XL, with the exception that it also accepts unfiltered vehicle power (6-40VDC) as a power source. This allows long-range communication within and among vehicle convoys and bases, and enables the bridging of widely spread networks by vehicles. BreadCrumb XLVs have been rapidly deployed: • In HMMWVs • In Bradley Fighting Vehicles • In trucks 13
