a. Light precipitation will reduce the range and performance of a BreadCrumb and wireless
clients.
b. Heavy precipitation or fog will most likely result in extremely reduced range and frequent or to-
tal loss of network connectivity.
4.4.2 Deployment Methodology
The deployment process for the mesh consists of deploying each BreadCrumb. The deployment process
for a BreadCrumb consists of installing the BreadCrumb hardware, powering up the BreadCrumb and
waiting for the BreadCrumb to boot. BC|Commander can then discover the BreadCrumb in the network.
To successfully deploy BreadCrumbs in the mesh, adhere to the following steps:
1. Scan the terrain where the mesh 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.
c. Plan the placement of each BreadCrumb to work around any LOS obstructions.
2. Identify the BC|Commander host(s) to be used for deployment.
a. A user who deploys BreadCrumbs must carry a portable BC|Commander host, such as a laptop
with a wireless Network Interface Card (NIC), to each BreadCrumb location.
b. A user who monitors the deployment of BreadCrumbs will need a stationary BC|Commander
host, such as a personal computer.
c. The users for the BC|Commander host(s) require a means of interpersonnal communication (ra-
dio, cell phone, etc.).
3. Determine the location for the first BreadCrumb.
4. Power ON the BreadCrumb.
5. Wait approximately 90 seconds for the BreadCrumb to boot.
6. Power ON the BC|Commander host(s).
7. Start BC|Commander on the BC|Commander host(s).
8. Ensure that BC|Commander displays the BreadCrumb in the BreadCrumb Table or Topology View.
9. Determine the approximate location for the next BreadCrumb.
10. Proceed to the location for the next BreadCrumb while monitoring the BreadCrumb connectivity in
BC|Commander. Do one of the following:
a. If the BreadCrumb loses network connectivity before reaching the target location, backtrack un-
til network connectivity is restored. The location where network connectivity is restored is most
likely the farthest point in this direction where this BreadCrumb can be placed.
b. If the target location is reached without losing connectivity, do one of the following:
Place the BreadCrumb in that location.
In an attempt to make optimal use of available BreadCrumbs, proceed until the
BreadCrumb loses network connectivity and then backtrack until network connectivity is
restored. The location where network connectivity is restored is most likely the farthest
point in this direction where this BreadCrumb can be placed.
11. For each remaining BreadCrumb, repeat Step 9 and Step 10.
