Pr eface Purpose and Scope This manual provides information and guidance to all personnel who are in volved with and use Rajant Corporation’ s BreadCrumb® Wireless Netw ork devices ("BreadCrumb® de vices") in tactical situations. This manual begins with an introduction to the BreadCrumb W ireless Network and a brief overvie w of the v[...]

Chapter 1. Intr oduction Rajant Corporation’ s (http://www .rajant.com) BreadCrumb W ireless Networks are portable, mobile, battery-powered, automati cally-meshing, self-healing, full-duplex, secure, 802.11b access points. Their focus is on flexibility , adaptability , and simplicity . The BCWN (BreadCrumb W ireless Network) is intended for rapi[...]

Chapter 1. Intr oduction Mobility thr ough Meshing The key component to a Brea dCrumb Wireless Netw ork is a technique known as Meshing . While this is generally handled automatically by BreadCrumb de vices, complex deployment scenarios require a basic understanding of how BreadC rumb devices establish and maintain a mesh. Mesh - A Definition A me[...]

Chapter 1. Intr oduction Figure 1-1. Meshing Example 1 - Full Connecti vity Example 2 Now suppose that you change the ESSID of BreadCrumb device C to "lonely". The netw ork will adjust to this change, resulting in the follo wing configuration: Note that BreadCrumb devi ce C can no longer communicate with A or B, and vice versa. Figure 1-[...]

Chapter 2. Upgrading to V ersion 8.4 This section is only necessary for BreadCrumb de vice/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 F eatur es • Fortress T echnologies’ AES-256 encryption is enabled, allowing F ortress encryption to be used on [...]

Chapter 2. Upgrading to V ersion 8.4 • Selection of a unique ESSID (network name) for the BreadCrumb network is recommended. A BreadCrumb device equipped w ith 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 JR[...]

Chapter 4. Deployment Considerations Addr essing When routing to another network or when using its o wn embedded DHCP servers, the BreadCrumb W ireless Network requires that wireless de vices use IPv4 addresses in the Class A network 10.0.0.0/8 (that is, any address that be gins with "10."). If you are not connected to another network, or[...]

Chapter 4. Deployment Considerations In some cases, howe ver , it is necessary to manually set the radios to specific channels as described below .

Chapter 4. Deployment Considerations Unobstructed LOS is not necessary from e very BreadCrumb device and wireless client to e very other BreadCrumb device and wir eless client. Howe ver , each device must ha ve unobstructed LOS to the previous and subsequent de vice. Distance Many factors determine ac ceptable distances between BreadCrumb devices w[...]
