2.4.2 Mounting the Unit
This section describes how to mount the NEXUS and position the antenna. It contains the
following sections:
•
Choosing a Mounting Location and Site Survey
•
Assembling the Mounting Hardware
•
Mounting the NEXUS
Choosing a Mounting Location and Site Survey
Every RF application is a unique installation. Before installing, you should perform a site
survey to determine the optimum use of wireless networking components and to
maximize range, coverage, and network performance.
Choosing a good mounting location for the NEXUS is important because it affects the
reliability of the wireless link and maximum data rates it can support. The most important
considerations are link length and clearance from obstacles.
The following operating and environmental conditions should be taken into account when
performing a site survey:
•
Data rates—Sensitivity and range are inversely proportional to data bit rates. The
maximum radio range is achieved at the lowest workable data rate. A decrease in
receiver sensitivity occurs as the radio data increases.
FCC ID PWG NEXUS 1

Installation Manual
•
Antenna type and placement—Proper antenna configuration is a critical factor in
maximizing radio range. As a general rule, antenna height helps to reach longer
distances to avoid obstruction. However, do not place the antenna higher than
necessary, because the extra height also increases potential interference from
other unlicensed radio systems. Do not install the airHaul Nexus on a TV or
Radio receiving mast or within proximity of the same.
•
Physical environment—Clear or open areas provide better radio range than closed
or filled areas.
•
Obstructions—Physical obstructions such as buildings, trees, or hills can hinder
performance of wireless devices. Avoid locating the devices in a location where
there is an obstruction between the sending and receiving antennas.
Link Distance
In an environment without obstacles in the signal path, the maximum link distance
depends primarily on the type of antennas and the free space path loss. Make sure your
proposed mounting site is within range of the remote antenna. The NEXUS units have a
built-in Link Analysis Calculator to help you estimate the range for your specific
installation.
Antenna Polarization
The antennas radiate and receive polarized radio signals. Polarization helps reduce
interference because the antenna tends to reject cross-polarized signals from other
sources. Therefore, you can solve some interference problems by changing the antenna
polarization. For the link to operate correctly, two antennas at each end of the link must
always be set for the same polarization, either vertical or horizontal. The NEXUS
mounting hardware accommodates either vertical or horizontal antenna polarization.
Signal Path Clearance (Fresnel Zone)
A radio beam travels from one antenna to another in a straight line. Therefore, the path
between the antennas must be free of major obstacles. The effects of obstacles and
terrain, both along and near the path, have a significant bearing on the propagation of
radio signals and can cause both interference and signal cancellation.
When choosing a site, consider the effects of the following common obstacles:
•
Trees and large plants - A tree directly in the path can totally block the signal.
With clearance above the trees there are usually no secondary effects, but you
should allow for future tree growth.
•
Man-made obstacles - A large round container such as a gas storage reservoir or
water tower that is partially in the path causes some blocking. These obstacles
may also reflect some energy, which can interfere with other receivers. Square or
rectangular objects in or near the path have rectangular surfaces that can block
and diffract signals over and around them.
•
Earth surface - The earth surface also interferes with signals if the antenna is
mounted too low. Mount the antenna just high enough to allow adequate
clearance from the ground. Placing the antennas too high makes it susceptible to
interference from other systems.
FCC ID PWG NEXUS 1

Installation Manual
For tower installations, you may need to climb the tower to verify a clear path to the other
site. If trees are in the line of signal propagation, leave extra clearance above them for
future growth into the signal path.
Table 5-1 (below) can be used as a guide to determine the clearance to leave around the
signal path. Install the bridge or external antenna where obstacles along the propagation
path, including the ground, are no closer than these values.
