3.4.1 Deployment Guidelines
Follow these guidelines when deploying the BCWN:
1. Placement of BCWN components
(a) Elevate the BCWN components whenever possible.
i. Directly on the ground, the maximum distance between any two BCWN components
is approximately 300 ft. Also, the maximum distance between a wireless client and
the nearest BCWN component is approximately 300 ft.
ii. Rajant recommends elevating each BCWN component a minimum of 6 ft. above the
surrounding terrain for maximum range. Elevating the BCWN components, as little
as 14 inches, has proven to increase the range out to approximately 600 ft.
2. Distance
(a) If you cannot elevate the BCWN components, they can only be approximately 300 ft.
apart. Also, any wireless clients can be no farther than approximately 300 ft. from a
BCWN component.
3. Line of sight
(a) Obstructions to line of sight block/absorb/deflect the wireless network’s radio waves,
resulting in poor network performance or total loss of network connectivity.
(b) When placing the BCWN components, scan the area for LOS obstructions. Envision the
BCWN’s radio waves as a light beam. Look for obstructions that would result in
shadows in the light beam, they will most likely weaken or block the BCWN’s radio
waves.
4. Weather
(a) Light precipitation will reduce the range and performance of the BCWN components and
wireless clients.
(b) Heavy precipitation or fog will most likely result in extremely reduced range and
frequent or total loss of network connectivity.
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.
Refer to
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
