2-4 Hardware Installation
The Orion-900, 900MHz ISM band radio is a radio device, so it is susceptible to common causes of
interference that can reduce throughput and range. Follow these basic guidelines to ensure the best
possible performance:
If there is any other 900MHz RF device deployed in the area, try to set the channel to one
that does not overlap the interferer. If you are not able to determine what channel the
interferer is on, randomly select a channel until the channel with the best signal strength is
locked in.
A clear line-of-sight path can guarantee the best performance. Ensure proper antenna height
and no obstructions. Although the Orion-900 can be forgiving under certain circumstances,
it is always recommend that. clear line of sight is achieved.

Chapter 3 Antenna and RF Tutorial
Selecting Antenna Type
There are a vast number of antenna types designed for various general and special purposes, but
despite the huge variety, all designs essentially address two concerns, directionality and gain. These
selection criteria are discussed in the following paragraphs, along with a third criterion, polarization.
Directionality
An antenna may be designed to receive and transmit in all directions. Such antennas are
omni-directional. An example of an omni-directional receiving antenna would be a television antenna
in a metropolitan area where each television station transmits its signal from a different location
relative to the receiver. Similarly, a centrally located television transmitter would use an
omni-directional transmitting antenna.
The sensitivity and power of an omni-directional antenna are unfocused; that is, they are spread
through a wide volume of space, so the advantage of being able to communicate in all directions is
traded off for limited sensitivity and power.
If it is determined that all signals of interest are coming from a definable direction, the
omni-directional antenna can be replaced by a directional or sectoral antenna, which increases
sensitivity and power by focusing the beam in the desired direction.
In practice, even omni-directional antennas take advantage of directionality by focusing their
sensitivity and power in the horizontal plane. Rather than waste performance by sending signals into
space or into the ground, the horizontal omni-directional antenna redirects its power and sensitivity
from these directions, increasing performance in the horizontal plane.
In point-to-point applications, where the direction of communication is known and fixed, a highly
focused directional antenna can be used to provide maximum sensitivity and power. In addition,
because of its decreased sensitivity in all directions but the desired one, the directional antenna
improves performance by rejecting signals not coming from the desired direction. This provides an
effective increase in signal-to-noise performance.
A sector antenna has a wider “spread” than a directional (generally between 60 to 120 degrees) which
makes it a cross between an onmidirectional and a directional. This is useful in a point to multipoint
configuration where multiple sites are grouped in the same general area. The installer can then
make use of the higher sensitivity and power but also take advantage of the wider beam pattern and
improved front to back ratio.

12
Gain
“Gain” specifies the receive and transmit performance of any antenna compared to a standard
omni-directional antenna (“spherical radiator”). The objective of a directional antenna design is to
achieve gain, improving sensitivity and effective radiating power to increase range or data rate.
Gain is measured and stated in decibels, abbreviated dB. The decibel is a unit used to indicate the
relative difference in power between two signals. For example, a signal 3 dB greater than another
signal has twice as much power. The decibel is a logarithmic unit so each doubling of decibels
represents a fourfold increase in power. Since 3 dB represents a doubling of power, 6 dB represents a
fourfold power increase, 12 dB represents a 16-fold increase, etc. For antenna performance, the unit
used is dBi, “i” standing for “isotropic,” which describes the standard spherical radiation pattern.
One type of directional antenna available from Wireless Interactive is called a “semi parabolic”. This
antenna has a gain of 24 dBi, representing power and sensitivity levels 256 times greater than those
of a standard omni-directional antenna.
Polarization
Another important concept for antenna performance is polarization. An antenna radiates radio waves
that vibrate in a specific plane, normally horizontal or vertical. Polarization refers to the restriction of
wave vibration to a single plane.
Do not confuse polarization with directionality. The plane of wave vibration has nothing to
do with the direction of wave propagation. For example, an antenna that focuses its energy
in the horizontal plane may be vertically or horizontally polarized.
Designs such as the semi parabolic offer a choice of polarization. Mounting a semi parabolic antenna
with the elements horizontal provides horizontal polarization, while mounting the antenna with the
elements vertical provides vertical polarization. Similarly, the orientation of the radiating element of
the parabolic antenna determines polarization.
In setting up the Wireless Interactive system, either vertical or horizontal polarization can be used, as
long as polarization is the same at both ends of each link. For any given pair of line-of-sight antennas,
it is essential that they both have the same polarization. Differences in polarization among antennas –
called “cross-polarization” – can reduce signal considerably.
Site Selection
At the high operating frequencies of a Wireless Interactive system, radio waves travel in a nearly
straight line-of-sight path. This is in contrast to the lower-frequency radio waves used for AM
broadcasting. These waves bounce between the ionosphere and the earth’s surface to travel long
distances and operate over and around obstructions. Higher-frequency radio waves do not behave in
this manner and are greatly weakened by substantial obstructions or the absence of a direct path.
Simply put, all antennas communicating with each other in the radio network must be able to
physically “see” each other.

13
For this reason, a proper antenna site must meet the following criteria:
1. For optimum performance at maximum range, there must be a clear line-of-sight path among all
antennas that communicate directly with each other. At shorter ranges, some degree of
obstruction may be tolerated, but performance in the presence of obstruction is difficult to
predict.
2. Elevating one or more of the antennas in the system increases maximum line-of-sight range,
called the radio horizon. If antennas are located at a greater range than the ground-level radio
horizon, a means must be available for elevating the antennas.
3. All antennas must be properly oriented, and a directional antenna must be carefully aimed at its
target antenna to ensure communication at maximum range.
4. All antenna RF cables attenuate (reduce) signal strength in proportion to their length. Therefore,
the distance between the antenna and the radio is limited to a cable length that does not exceed
the maximum attenuation tolerated by the system. Since various cable types offer different
attenuation levels, maximum length depends on cable type. Generally speaking, because most
Wireless Interactive systems are outdoor units with the output port connected directly to the
antenna, cable losses are negligible and the radio will compensate, but there are limits to this
compensation. See table 4-2 for sample cables and their respective attenuation values.
Line-of-Sight Path
Because high-frequency radio waves are attenuated by obstructions, a clear line-of-sight path between
antennas is required for optimum performance at maximum range. For shorter ranges, a degree of
obstruction may be acceptable. For example, at less than maximum ranges the radio has some ability
to “penetrate” trees and other foliage. On the other hand, geographical features (hills) and large
buildings are likely to interfere with communications, and antennas must be elevated to “see” each
other above such objects.
Because of the uncertainties of radio communication, it is difficult to predict the results in
conditions where obstructions exist. The only valid advice is to try the proposed configuration and
be prepared to move or elevate the antennas.
Radio Horizon (Maximum Line-of-Sight Range)
In visual terms, the horizon is the point in the distance where an object drops out of sight because it
is blocked by the earth’s curvature. If the observer or object is elevated, the visual horizon is
extended, that is, the object can be seen at a greater distance before it drops out of view.
The same concept applies to radio signals: The radio horizon is the point in the distance where the
path between two antennas is blocked by the curvature of the earth. Like the visual horizon, the
radio horizon can be extended by elevating the transmitting antenna, receiving antenna, or both to
extend communication range.
The radio horizon can also be extended or shortened by certain phenomena such as refraction due to
atmospheric density and temperature inversions. Fog and rain, which reduce signal strength, can also
shorten the radio horizon although in the ISM band, this loss is negligible.

14
A reasonable approximation of the radio horizon based on antenna height can be obtained from the
graph below. (Note that this graph does not take atmospheric effects into account.) To use the graph,
set a straight edge so that it crosses the height of one of the antennas in the column on the left and
the height of the other antenna in the column on the right. The radio horizon in miles/km is shown
where the straight edge crosses the center column.
Antenna Height and Radio Horizon Graph
If the radio horizon is well within maximum communication range of the system, this graph
provides a reasonable guide for antenna height. However, as maximum range of the system is
approached, results are less reliable because of atmospheric effects and other unpredictable
phenomena. In such cases, the more thorough point-to-point path analysis described in the next
section should provide more reliable results.

15
Point-to-Point Path Analysis
A full point to point analysis should consist of at a minimum, a background noise evaluation of all
locations where radios are to be installed, a determination of the minimum antenna height required
to obtain a “line-of-sight”, and a calculation of the expected RSS level to be received at each of the
locations. The background noise measurement is critical as it gives the operator a preview of the
potential performance variations and the feasibility of utilizing a particular radio at a location. For
example, if the background noise is found to be at the same level as the radio sensitivity (when set to
maximum speed), a tradeoff analysis can be conducted before installation to determine if lowering
the data rate will allow the radio sufficient link margin to operate. A line-of-sight is required to insure
the best performance from the radio. This information, when coupled with the background noise
measurement, will tell the operator if a link can be established and give a reasonable “a priori”
estimate of the performance of the system. In addition to this, the RSS level allows the operator to
do a quick check on the integrity of the system installation by verifying that the received RSS level is
close to the calculated value. Analysis can be provided by an approved radio technician.
Antenna Orientation
Antennas at each end of a communications link must be mounted similarly in terms of polarity, and
directional antennas must be carefully oriented towards each other. The choice of polarization –
horizontal vs. vertical – is in many cases arbitrary. However, interfering signals from such devices as
cellular phones and pagers are generally polarized vertically, and an excellent means of reducing their
effect is to mount system antennas for horizontal polarization. While omni-directional antennas use
only vertical polarization, horizontally polarized omni-directional antennas are available.
Orientation of directional antennas is critical because their sensitivity is greatly reduced outside a
fairly narrow angle. Performance of the system can be seriously degraded by mis-aligned directional
antennas.
Cable Loss (Attenuation)
Using short cables to connect the radio to the antenna reduces signal losses. The below table shows
loss per 100 feet (30 meters) at 2.4 GHz for typical antenna cable types.
Loss at 900 MHz for LMR Equivalent Coaxial Cable Types
Cable Type Loss per 100 ft. (30 m)@ 900 MHz
LMR 195 11.1 dB
LMR 400 3.9 dB
To determine total cable loss for your installation, perform the following calculation:
For US units, multiply length in feet by the loss figure and divide by 100.
For metric units, multiply length in meters by the loss figure and divide by 30.
For example, for a 75-foot length of LMR 400 cable, the loss is: 2.92 dB

16
Connector Loss
Loss is introduced with each pair of cable connectors. Attenuation losses of some standard cable
types are shown in the following table:
Connector type Loss per connector
Most RF Connectors 0.25 dB
The loss of each pair of connectors on all cables must be included to determine the total signal loss
(attenuation) between the antenna and ODU.
Other Considerations – Antenna Grounding
WARNING: VERY IMPORTANT INFORMATION
As an elevated metal object with a wire connection below, an antenna is an excellent lightning
attractor, and an effective ground must be provided to deflect lightning strikes to ground. An
additional advantage of effective system grounding is the minimizing of electrical noise and
interference, which can significantly degrade system performance.
Grounding involves providing a good, very low resistance connection from the antenna and radio to
earth ground to provide a better path for lightning and electrical noise than that through the
equipment. The following points should be taken into account in setting up system grounding:
•The antenna should be mounted on a mast or tower that is well grounded to earth.
•All antenna lead connectors should be correctly installed to provide a good, solid connection to
the cable shield.
•Threaded couplings mating antenna lead connectors should be clean and tight; bayonet type
connectors should not be used.
•Weatherproof connectors must be used for outdoor connections to prevent corrosion, which
will interfere with grounding.
•All power and antenna grounds should be made common at a single point such as an equipment
rack, cabinet enclosure chassis, or antenna tower. This single-point ground should have a solid
ground connection to earth.
•A surge arrestor or lightning protector should be installed at the point where the antenna cable
enters the building or cabinet. The lightning protector should be properly grounded at the
single-point chassis ground. Carefully follow the installation instructions provided by the
manufacturer of the protection device. An appropriate lightning protector is available from
Wireless Interactive.
