Path Profile

The path profile should include the following information:
Site Location
Antenna Height
Antenna Azimuth
Antenna Elevation
Expected RSSI
The site survey should identify the optimum location for mounting the wireless terminal.
For maximum performance, there should be a direct line of sight between all
communicating wireless systems. A clear line-of-sight (LOS) path requires clearance
above natural and man-made objects by at least 60% of the First Fresnel zone. Each
antenna should be positioned to provide maximum clearance in the first Fresnel zone of
the direct signal path.
The wireless terminal also functions under optical line-of-sight (OLOS) conditions; where
a clear straight line path exists between the two end points, but the first Fresnel zone is
not clear of obstacles. If the optical path is completely blocked, it may be possible to
establish a non line-of-sight (NLOS) path using RF signal reflections, such as a common
reflective structure (e.g., large building) that is LOS for the antennas of communicating
units.
For best results:
Mount the antenna in a location that provides an unobstructed view of the horizon.
-
Avoid mounting the antenna close to metal objects that may block/reflect the signal.
-
To minimize susceptibility to radio interference, the antenna should generally be
-
located at least 1 m (~3.25 ft) away from any another high frequency system
antennas (e.g., microwave, GSM, CDMA, 3G) and should not be mounted within the
main beamwidth of any active (radiating) antenna system.
