    Follow these guidelines to decide where to mount your two Lighthouse base stations:
 
    - They should be centered above and facing the area that will be occupied by the lighthouse receivers.

      has a 120° field of view. However, position measurements are noisier when receivers are at the boundary 
      of the transmitters' range, so leave a safe margin. A receiver must be in range of both transmitters 
      in order to measure position.
