Figure 19. Deployment Configuration - Reach Area
RCHPT01 in could be the command post at an incident, placed a safe distance from the threat. Each of the
remaining BCWL components would provide continuity of the wireless network into the threat area.
It should also be noted that this deployment configuration does not have to stretch out in a perfectly straight line.
The BCWL component placement can be altered (following the guidelines and methodology in Section 3.4) to ‘go
around’ obstructions (such as buildings, terrain, etc.).
4.6 DEPLOYMENT GUIDELINES AND METHODOLOGY
This section addresses the actual onsite deployment of the BCWL. While no means an exhaustive treatise, it is
intended as a good source of guidelines and methodology for the successful deployment of the BCWL in the field.
4.6.1 DEPLOYMENT GUIDELINES
Referring back to Section 3.2 (Deployment Considerations):
1. Placement of BCWL components
a. Elevate the BCWL components whenever possible.
i. Directly on the ground, the maximum distance between any two BCWL components is
approximately 300 ft. Also, the maximum distance between a wireless client and the
nearest BCWL component is approximately 300 ft.
ii. Rajant recommends elevating each BCWL component a minimum of 6 ft. above the
surrounding terrain for maximum range. Elevating the BCWL 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 BCWL components, they can only be approximately 300 ft. apart. Also,
any wireless clients can be no farther than approximately 300 ft. from a BCWL component.
3. Line of sight
a. Obstructions to line of sight block/absorb/deflect the wireless LAN’s radio waves, resulting in
poor network performance or total loss of network connectivity.
b. When placing the BCWL components, scan the area for LOS obstructions. Envision the BCWL’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 BCWL’s radio waves.
4. Weather
a. Light precipitation will reduce the range and performance of the BCWL components and wireless
clients.
