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.

 3.4  Deployment Guidelines and Methodology

This section addresses the actual on-site deployment of the BCWN.  While by no means an 
exhaustive treatise, it is intended as a good source of guidelines and methodology for the successful 
deployment of the BCWN in the field.

 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.
