You can mount the Bridge on a flat surface, such as a desk or table, or on a vertical surface, 
such as a wall. It can also be mounted on the ceiling. If you mount the Bridge vertically, use the 
supplied mounting cradle previously described. 
 
Choosing a good location for the Bridge is important because it affects the reliability of the 
wireless link. The most important considerations are distance from the Access Point and 
clearance from obstacles.  
 
When considering a location for installing the Bridge, ensure that it: 
 

ƒ

  Provides sufficient ventilation around the Bridge. 

ƒ

  Allows easy access to disconnect the Bridge from the AC wall outlet if necessary. 

ƒ

  Does not expose the Bridge to excessive heat, humidity, vibration, or dust.  

ƒ

  Conforms to local regulations. 

 
Because radio waves travel in a straight line, the location where you will install the Bridge must 
provide a clear path to the Access Point that is free of major obstacles. The effects of obstacles, 
both along and near the path, have a significant bearing on the travel of radio signals and can 
cause both interference and signal cancellation. Consider the effects of the following common 
obstacles: 
 

ƒ

  Trees and large plants 

A tree or large plant directly in the path can totally block the signal. With clearance 
above the trees, there are usually no blocking effects. 

ƒ

  Man-made obstacles 

Square or rectangular objects, in or near the path, have rectangular surfaces that can 
block and interfere with signals over and around them. 

ƒ

  Floor 

A floor can interfere with signals if the Bridge is mounted too low. Mount the Bridge so 
the antenna is high enough to allow adequate clearance from the floor.
