 4.4.2  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.

Refer to 

Rajant Troubleshooting Range User Guide

 for more information.

(b) Note any LOS obstructions, and plan BreadCrumb placement to work around them.

 2. Identify the PC on which BC|Commander will be run.

(a) This PC should have a wireless NIC, as you will need to carry it with you as you deploy 

the BCWN.
 i. Alternatively, the BC|Commander PC can be stationary with one person monitoring 

BC|Commander while another deploys the BreadCrumbs.  This method requires some 
form of communication (radio, cell phone, etc.) between the two persons.

 3. Determine the location for the first BreadCrumb.
 4. Power ON the device.
 5. Wait approximately 90 seconds for the device to boot.
 6. Power ON the BC|Commander PC.
 7. Start BC|Commander.
 8. The BC|Commander console should display the first BreadCrumb.
 9. Determine the approximate location for the next BreadCrumb.
 10.Proceed to the location for this BreadCrumb, observing the network in BC|Commander as 

you progress.
(a) If the BreadCrumb loses network connectivity before you reach its destination, backtrack 

until network connectivity is restored.  The point at which network connectivity for this 
BreadCrumb is restored is most likely the farthest point in this direction at which you will 
be able to place this BreadCrumb.

(b) If you reach the destination without losing connectivity you can place it there.

 i. At this point, you may choose to proceed farther in an attempt to make optimal use of 

the available BreadCrumbs.

 ii. If so, proceed until network connectivity is lost and then backtrack until network 

connectivity is restored for this BreadCrumb.  The point at which network 
connectivity is restored for this BreadCrumb is most likely the farthest point in this 
direction at which you will be able to place this BreadCrumb.

 11.Repeat steps 9 and 10 for any remaining BreadCrumbs.
