Unsupported Setups
You cannot install the following colocated systems in the 5 GHz band in Europe:
„
A point-to-point repeater with a point-to-point link. In this setup, two masters do not
see each other, S3100 2 and S1100-R 2, while the two receivers do.
„
Multiple point-to-point repeaters. The S3100 2 and S3100 3 masters do not see each
other, while the two receivers do.
RF Planning
Successful operation of a wireless link depends on proper RF path planning and antenna
installation. You have to install the devices in such a way that there is a clear RF line of
sight between the two antennas.
Location Evaluation
The path between the two antennas must be free of obstacles that could disturb
propagation. For very short link distances—less than 500 feet (152 meters)—you may be
able to establish a working link despite partial path obstruction. However, radio waves will
be in part absorbed and in part diffracted by the obstacles, therefore affecting link
reliability. Because the reliability of such an installation is highly unpredictable, Verint does
not recommend it. A path free of any obstacle is called an RF line-of-sight path.
To establish an RF line-of-sight path, you must take into account the beam width of the
radio signal transmitted between the two antennas. This beam width is an elliptical area
immediately surrounding the visual line of sight. It varies in thickness depending on the
length of the line of sight; the longer the length, the thicker the beam width becomes.
