Radio Management Settings
The following table contains the minimum set of parameters required to configure the
wireless interface. Note that these settings are made independently of the Serial
Gateway settings using the

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.
