BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 Preface Purpose and Scope This manual provides information and guidance to all personnel who are involved with and use Rajant Corporation’s BreadCrumb LX/LX3 products. This manual begins with an introduction to the BreadCrumb Wireless Network (BCWN). It then characterizes the features of the BreadCrumb LX/LX3. Finally, it describes common deployment scenarios and provides concise step-by-step instructions for each scenario.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 1 Introduction to BreadCrumbs Rajant Corporation's (http://www.rajant.com) BreadCrumbs utilize the 802.11 wireless networking standards to form a wireless mesh network. The network is mobile, self-integrating, self-meshing, self-healing, and secure. The focus is on flexibility, adaptability, and simplicity.
BreadCrumb® LX/LX3 User Guide Version: 3.00 1.2 Rajant Corporation 03-100101-001 Mobility through Meshing The key component to a BCWN is a technique known as Meshing. While this is generally handled automatically by BreadCrumbs, complex deployment scenarios require a basic understanding of how BreadCrumbs establish and maintain a mesh. 1.2.1 Mesh – A Definition A mesh is a collection of network devices (in our case, BreadCrumbs), each of which is linked to one or more other BreadCrumbs.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 Example 1: Suppose you have three BreadCrumbs, called A, B, and C. Each has two radios. BreadCrumb A’s radios are on channels 1 and 8, B’s are on 8 and 11, and C’s are on 1 and 11. All three BreadCrumbs are using the default ESSID of "breadcrumb54-v10.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 2 Description of a BreadCrumb LX/LX3 The BreadCrumb LX/LX3 is a portable, wireless device deployable in almost any environment. It is light in weight, and offers up to 3 external antennas, and is designed to be completely mobile as worn by an individual. The BreadCrumb LX/LX3 must be powered by an external source. 2.1 Radios BreadCrumb LX offers two radios, while BreadCrumb LX3 offers three radios. 802.

Rajant Corporation 03-100101-001 Tip BreadCrumb® LX/LX3 User Guide Version: 3.00 The process of zeroizing keys and restoring factory defaults can also be performed remotely from within the BC|Commander management software. For details on this alternative method, refer to the BC|Commander User Guide.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 3 Using BC|Commander BC|Commander is Rajant’s software package used for monitoring the status of BreadCrumbs with version 10 firmware on a BreadCrumb Wireless Network (BCWN). BC|Commander is also used for configuring version 10 BreadCrumbs and to graphically portray the network topology. Note BC|Commander includes an option called v10 Transitional Mode.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 4 Deploying the BreadCrumb Wireless Network There are many factors which need to be taken into account when deploying the BreadCrumb Wireless Network (BCWN). Section 4.1 describes the addressing scheme of the BCWN. Section 4.2 discusses channel assignments. Section 4.3 details some of the most commonly occurring environmental factors that will have a major impact on the performance of the BCWN. Finally, section 4.

This can be especially important when using single-radio BreadCrumb devices. Refer to the BC|Commander User Guide for the details of BreadCrumb channel configuration. 4.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 the performance of the system. ● Devices placed too far away or in RF “shadows” may experience total loss of connection. ● RF transmit power and receive sensitivity are important in determining the distances over which the device will be effective. ● When placing a BreadCrumb device, check the connection status to the nearest available device using either the BreadCrumb device’s status LED (described in section 2.
BreadCrumb® LX/LX3 User Guide Version: 3.00 4.3.5 Rajant Corporation 03-100101-001 Placement of BCWN Components The placement of BreadCrumb devices has a major impact on maximum effective range, and therefore network performance. The components must be elevated above the surrounding terrain to allow for adequate wave propagation. A device placed directly on the ground has a significantly reduced effective range. Elevating a device above the ground dramatically increased the maximum effective range.
Rajant Corporation 03-100101-001 4.4.2 BreadCrumb® LX/LX3 User Guide Version: 3.00 Deployment Methodology The steps detailed in this section should assist you in successfully deploying the BCWN. 1. Scan the terrain on which the BCWN will be deployed. (a) Determine the initial distances between BreadCrumb devices. Refer to Rajant Troubleshooting Range User Guide for more information. (b) Note any LOS obstructions, and plan BreadCrumb placement to work around them. 2.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 5 BreadCrumb LX/LX3 Firmware Upgrade Each BreadCrumb relies on low-level software known as firmware for proper execution. For a BreadCrumb to communicate with other BreadCrumb devices or a BC|Commander client, the firmware version of the device must be compatible with the firmware versions of all other devices within the network, and with the version of BC|Commander running on the client computer.
BreadCrumb® LX/LX3 User Guide Version: 3.00 Rajant Corporation 03-100101-001 sequence of long and short blinks in red, indicating the error code. Take note of the error code (see Appendix A for an explanation of error codes). Leaving the USB storage device connected, turn power to the BreadCrumb OFF and then ON again. Observe the Status LED to monitor progress. If, during this second firmware upgrade attempt, another error occurs, take note of the new error code and then apply for technical support. 6.
