Rajant Corporation BreadCrumb ® LX/LX3 User Guide 03-100101-001 Version: 2.91 Deploying the BreadCrumb Wireless Network There are many factors which need to be taken into account when deploying the BreadCrumb Wireless Network (BCWN). Section 3.1 describes the addressing scheme of the BCWN. Section 3.2 discusses channel assignments.
BreadCrumb ® LX/LX3 User Guide Rajant Corporation Version: 2.91 03-100101-001 In some cases, however, it is necessary to manually set the radios to specific channels as described below. 3.2.1 Channel Assignment for Single-Radio BreadCrumb Devices Single-radio BreadCrumb devices such as the ME2 present a challenge for deployments in which those BreadCrumb devices are needed to provide critical links within a mesh.

BreadCrumb ® LX/LX3 User Guide Rajant Corporation Version: 2.91 03-100101-001 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 recommends elevating the components a minimum of 6 ft. above the surrounding surface.
Rajant Corporation BreadCrumb ® LX/LX3 User Guide 03-100101-001 Version: 2.91 3.4.2 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.
