FCC Output Power Restrictions
The FCC does not require licensing to implement this device. License-free operation in the industrial,
scientific, and medical band is documented in FCC Rules Part 15.247. It is the responsibility of the
individuals designing and implementing the radio system to assure compliance with any pertinent FCC
Rules and Regulations. This device must be professionally installed.
Exposure to Radio Frequency Fields
The TRACER 5045 is designed to operate at 5.8 GHz with 100 mW maximum transmit power.
This level of RF energy is below the Maximum Permissible Exposure (MPE) levels specified in FCC OET
65:97-01. The installation of high gain antenna equipment in the system configuration may create the
opportunity for exposure to levels higher than recommended for the general population at a distance less
than 15 feet (4.6 meter) from the center of the antenna. The following precautions must be taken during
installation of this equipment:
•
•
•
•
•
•
•
The installed antenna must not be located in a manner that allows exposure of the general population to
the direct beam path of the antenna at a distance less than 15 feet (4.6 meters). Installation on towers,
masts, or rooftops not accessible to the general population is recommended; or
Mount the antenna in a manner that prevents any personnel from entering the area within 15 feet (4.6
meter) from the front of the antenna.
It is recommended that the installer place radio frequency hazard warnings signs on the barrier that
prevents access to the antenna.
Prior to installing the antenna to the TRACER 5045 output, make sure the power is adjusted to the
settings specified in section 2 of this manual.
During antenna installation, be sure that power to the TRACER equipment is turned off in order to
prevent any energy presence on the coaxial connector.
During installation and alignment of the antenna, do not stand in front of the antenna assembly.
During installation and alignment of the antenna, do not handle or touch the front of the antenna.
These simple precautions must be taken to prevent general population and installation personnel from
exposure to RF energy in excess of specified MPE levels.

Section 2 Microwave Path Engineering Basics
LINE-OF-SITE
The TRACER 5045 system is designed for operation in the license-free 5.725 GHz to 5.850 GHz
industrial, scientific and medical (ISM) band. Radio wave propagation in this band exhibits microwave
characteristics which are ideally suited for point-to-point, line-of-sight communications. Line-of-Sight
requires that the transmitting antenna and receiving antenna are able to “see” each other, and that the
straight-line path between the two antennas is free of obstructions, such as buildings, trees, mountains, and,
in longer paths, even the curvature of the earth. In addition, for maximum signal strength the area around
the visual line-of-sight where microwave signals reflect (Fresnel zone) must also be free of obstructions.
Fresnel zones are discussed in more detail on page 21.
Terminology
2.
Point-to-Point
Wireless communication from a single site to another individual
site. Contrast with point-to-multipoint.
Line-of-Sight
An unobstructed, direct path exists between the transmitting and
the receiving antennas.
DECIBELS
Understanding the decibel (dB) format is key when discussing microwave path engineering because the
received signal power is often expressed in decibel format. In general, any quantity can be expressed in
decibels. If the quantity x is a power level (in Watts), the decibel equivalent is defined as
(dB)
x dB = 10 ⋅ log 10 ( x )
If the quantity x is referenced to a milliwatt (mW), then the decibel-milliwatt (dBm) is used instead of a
generic decibel.
x dBm = 10 ⋅ log 10  -------------
 1mW
(dBm)
Using the decibel format simplifies power calculations by reducing multiplication and division operations
into addition and subtraction operations.
3.
CALCULATING THE FADE MARGIN
It is imperative to determine if the proposed microwave path is suitable (at a minimum) for
ideal, nondistorted signals before attempting installation.
The fade margin (F ) is a value indicating the amount of extra signal power available to the receiver to
operate at a maximum bit error rate (BER). Fade margin is simply the difference between the available
signal power at the receiver (PR ) and the receiver sensitivity (Psens ).
F = P R – P sens

Section 2 Microwave Path Engineering Basics
TRACER 5045 System Manual
Higher levels of fade margin indicate stronger protection against signal fading and a more reliable link. For
most applications, 20 to 30 dB of fade margin should ensure a reliable link.
The following sections further discuss the necessary power calculations and their components.
4.
RECEIVER POWER
The viability of a particular microwave path is determined by the power of the transmitted microwave
signal, the transmit and receive antenna gain, distance, and accumulated system losses (such as RF coaxial
cable losses and path loss).
The equation relating received signal power to the other microwave parameters is
PT GT GR λ
P R = -----------------------------( 4π )2d2L
(Watts, W)
or (in decibel notation)
PR = PT + GT + GR - L - LP
(decibels referenced to a Watt, dBW)
where the variables in the equation are defined as

transmitted power (100 mW (max) for TRACER 5045 - adjustable)
transmit antenna gain
receive antenna gain
carrier wavelength (meters)
path distance (meters)
other losses (RF coaxial cable, etc.)
path loss (dB)
When using decibel notation, all quantities must be individually converted to decibels
prior to performing addition and subtraction.

power budget analysis.

The following sections further discuss the power budget analysis and its components.
Antenna Gain
Actual transmit and receive antenna gain values depend strictly upon the physical characteristics of the
antennas installed for each link. In other words, the size of the dish determines the antenna gain. Using a
parabolic dish antenna results in the best performance. Antenna gains are specified in terms of decibels of
gain referenced to an isotropic source (dBi). An isotropic source is a hypothetical antenna having equal
radiation in all directions. Typical antenna gains are listed in Table 1; however, dish manufacturers can
provide gains for specific types of antennas.

Transmitted Power (PT)
The FCC specifies the maximum transmitter power used for antennae of a given gain. FCC Rules Part 15,
Subpart 247 allow for a maximum power of 1 Watt (30 dBm) into antennae of a gain less than or equal to
6 dBi. Since the TRACER 5045 maximum transmit power is 100 milliwatts, there is no reduction in
transmitter output power required for antennae gains greater than 6 dBi.

TRACER 5045 System Manual
Carrier Wavelength (λ)
The carrier wavelength is the physical wavelength of the main RF carrier being used for communication,
and is usually approximated at the center frequency of the band (which is 5787.5 MHz for the
TRACER 5045). The carrier wavelength calculations follow:
λ = c / f (meters)
where
c = speed of light (in meters)
f = frequency (in Hz)
resulting in the following carrier wavelength:
λ = 3.00 x 10¯8 / 5787.5 x 10 5
= 0.0518 m or 5.18 cm
Path Distance (d)
The path distance is simply the physical distance between the transmit and receive antennas. For the
TRACER 5045, these distances can range up to 30 miles.
System Losses (L)
System losses are defined by RF coaxial cable loss, connector losses, and losses added from any additional
lightning protection devices for the power budget analysis. Coaxial cable is required to attach the
TRACER 5045 to the antenna. The length of the cable varies from a few feet to several feet, depending
upon your application and the proximity of the TRACER 5045 to the antenna. Various grades of coaxial
cable will work sufficiently well for connecting the TRACER 5045 unit to the antenna. A low-loss coaxial
cable will minimize cable losses.
One end of the coaxial cable requires an N-type male connector (plug) to mate with the TRACER 5045
unit. The other end of the coaxial cable requires a connector compatible with the antenna chosen for the
installation (usually an N-type male connector). Additionally, ADTRAN recommends that the outdoor
connector on the coaxial cable be weatherproofed to prevent corrosion and electrical shorting.
In areas where lightning strikes are frequent, a lightning arrestor should be installed
directly on the antenna coaxial cable. Installing lightning arrestors helps protect the
RF electronics in the downstream path from damaging voltages and currents
(including the TRACER 5045 unit).

Path Loss (LP)
Path loss is the estimated attenuation between the transmit and receive antennas caused by signal
separation and scattering. The path loss is considered basic transmission loss over the microwave link. The
following expression calculates path loss:
4 π df 2
4πd 2
L P =  ---------- =  ------------
 c 
 λ 
(dB)
where
λ
carrier frequency (Hz)
carrier wavelength (c / f) (meters)
path distance (meters)
speed of light, free-space (meters)
or
L P = 96.6 + 20 ⋅ log 10 ( d ) + 20·log
10
(f)
(dB)
where d is expressed in miles and f in GHz
Path loss, as shown here, increases rapidly as either the path length increases or the carrier wavelength
decreases (which happens as the carrier frequency increases). Therefore, longer microwave paths naturally
experience more path loss than shorter paths. Likewise, higher frequency microwave communication
experiences more path loss than lower frequency microwave communication.

RECEIVER SENSITIVITY
Receiver sensitivity is a value expressed in decibels referenced to one milliwatt (dBm) that corresponds to
the minimum amount of signal power needed at the receiver to achieve a given bit error rate (BER).
Receiver sensitivity is usually a negative number of decibels and smaller receiver sensitivity (higher
quantity negative number) is better for a given BER. Several factors affect receiver sensitivity including
the data bandwidth of the wireless link, and the amount of additional signal degradation introduced in the
receiver electronics. The receiver sensitivity of the TRACER 5045 is -90 dBm at 10-6 BER.
Should an interferer be present nearby, three software selectable bandplans are provided
for frequency agility. Changing the TRACER 5045 bandplan does not require additional
components, or opening of the radio. See TRACER System Configuration > RF Bandplan
on page 47 for additional details.

ANTENNA INFORMATION
The overall wireless system is directly affected by the antenna selection and installation. The following
sections discuss several factors concerning antenna selection and installation.
Antenna Alignment
With line-of-sight microwave communications, optimum system performance requires that the
transmitting and receiving antennas are properly aligned. This ensures maximum received signal power at
each receiver. Antenna alignment must be achieved in both azimuth (along a horizontal plane) and
elevation (along a vertical plane). A received signal strength indicator (RSSI) aids the equipment installer
in determining when alignment is maximized by simply ensuring maximum RSSI.

612805045L1-1A
TRACER 5045 System Manual
Section 2 Microwave Path Engineering Basics
TRACER RSSI Test Points
The RSSI indicator for the TRACER 5045 system is provided through the VT100 terminal menus accessed
through the RS-232 interface, and it is presented as a series of bars indicating signal strength. More bars
means more RSSI, which ensures more received signal strength and better link performance.
If the local system has acquired a useful signal from the remote system, then the remote TRACER 5045
RSSI can be viewed from the local TRACER 5045 VT100 terminal menu interface.
An RSSI test point, located on the front panel, represents the voltage (relative to the GND test point) of a
relative signal level of receive strength from the far end. The voltage at this test point can vary from
approximatly 0 to greater than 4 Volts DC, with 0 Volts corresponding to no signal and 4 Volts or better to
full signal strength.
Antenna Beam Patterns
Directly related to the subject of antenna alignment is the topic of antenna beam patterns. Antennas used
with the TRACER 5045 system have a particular beam shape determined in part by the physical
construction and geometry of the antenna. The antenna beam patterns are characterized by a dominant
main lobe, which is the preferred lobe to use for point-to-point communications, and several side lobes, as
shown in Figure 1. When setting up a microwave link, antenna alignment is nothing more than steering the
main lobes of both antennas until the main lobe of one transmitter is centered on the receiving element of
the receiving antenna.
main lobe
side lobes
Figure 2. Typical Antenna Beam Pattern
Antennas are also designed to radiate RF energy efficiently for a specific range of frequencies. Please
consult the data sheet for your particular antenna make and model to ensure that it is specified to operate in
the 5725 MHz to 5850 MHz frequency band for the TRACER 5045 system.
Fresnel Zones, Earth Curvature, & Antenna Heights
Fresnel zones correspond to regions in the microwave path where reflections of the intended signal occur
and combine in both constructive and destructive manners with the main signal, thereby either enhancing
or reducing the net power at the receiver.
In general, the odd numbered Fresnel zones (1, 3, 5, ...) add constructively at the receiver, while the even
numbered Fresnel zones (2, 4, 6, ...) add destructively at the receiver.
612805045L1-1A
© 2003 ADTRAN, Inc.
21
Section 2 Microwave Path Engineering Basics
TRACER 5045 System Manual
The first Fresnel zone corresponds to the main lobe, 60% of which must be free of physical obstructions
for the path calculations to be valid. Since the main lobe contains the vast majority of the microwave
energy, this zone is typically used to determine proper antenna heights when placing antennas on towers or
buildings.
The curvature of the Earth becomes a legitimate obstruction for path lengths of 7 miles or greater, and must
also be accounted for when determining minimum antenna heights.
The aggregate expression for minimum antenna height that incorporates both the 60% first Fresnel zone
and the Earth’s curvature is given by
d- + 0.125d 2
h = 72.1 ---4f
(feet)
where f is in GHz and d is in miles.

OTHER CONSIDERATIONS
Path Availability
The path availability of a wireless link is a metric that expresses the fractional amount of time a link is
available over some fixed amount of time, and depends on several factors. Path availability is expressed as
A = [ 1 – ( 2.5 × 10
–6
– F ⁄ 10
)abfd ( 10
) ] × 100%
(%)
where the parameters are
terrain factor
climate factor
carrier frequency (GHz)
path length (miles)
fade margin (dB)
Terrain Factor (a)
The terrain factor is a quantity that compensates the link availability for different types of terrain.
Generally speaking, the more smooth an area's terrain is, the less availability a wireless link running over
that terrain will have, primarily due to multipath reflections. In contrast, secondary microwave signals will
be randomly dispersed over rough terrain, and will not interfere with the main signal lobe as badly as in the
smooth terrain case. The terrain factor values normally used are listed below:
Terrain
Terrain Factor
Description
Smooth
water, flat desert
Average
moderate roughness
Mountainous
1/4
very rough, mountainous
Climate Factor (b)
The climate factor is a quantity that compensates the link availability for different types of climates
(weather). In general, microwave links operating in areas with high humidity will have less availability
than those in arid areas, primarily because water is a dispersive mechanism to microwave energy, and
causes the main signal lobe to refract and disperse away from the receiver location. The climate factor
values normally used are listed below:

RSSI Monitoring Interface
The RSSI voltage is a function of the signal strength at the receiver and is used to measure the received
signal strength. RSSI varies approximately from 0 to greater than 4 Volts (V), with 0V corresponding to a
weaker received signal and 4V or better corresponding to a stronger received signal.
The voltage level present at the RSSI test point represents only a relative signal level of
receive strength from the far end. No direct correlation can be made between RSSI voltage
levels and actual receive levels in dBm. This test point is provided to assess relative signal
level for alignment of antennas.

RS-232 Connection (Modem Use)
Modem controls, discussed in Section 5, User Interface Guide, enable or disable modem control through
the RS-232 interface. When this option is enabled from a standard terminal connection, all RS-232
communications cease until a modem with a null modem adapter is attached between the TRACER 5045
and the data modem. Configure the data modem for AUTO ANSWER and 9600 BPS. When the user
connects via the modem to the TRACER 5045 unit, communications via the RS-232 port resume. If a user
accidentally enables modem control from a terminal and disrupts the RS-232 communication, pressing
 three times will temporarily disable the modem control option (until the system is reset) and
will access the system configuration to disable modem control.
The TRACER 5045 must be interfaced to a modem via an RS-232 null modem adapter or cable. The null
modem converts Clear To Send (CTS) and Data Set Ready (DSR) into Ready To Send (RTS) and Data
Terminal Ready (DTR), respectively. These signals indicate (to most modems) that a valid DTE terminal
device is present. The null modem interface must route Carrier Detect (CD) on pin 8 directly from the
modem. When using the RS-232 interface for modem control, the modem must source CD only when
actually connected to a carrier.
When MODEM CONNECTION is selected in the menu system, the TRACER 5045 will de-assert DTR and
DSR for a time greater than 20 msec. The null modem consequently drops DTR and RTS at the modem
interface, signaling the modem to hang up the line. If password functionality is enabled in the TRACER

CHANNEL SELECTION
The FCC has allocated 125 MHz of spectrum in the 5.8 GHz band where the TRACER 5045 operates.
Figure 1 illustrates the bandwidth division.
5725 MHz
5747
5827
5850 MHz
Figure 1. 5.8 GHz Bandwidth Division
To designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B.
The letter of each channel plan setting is preset by the factory and refers to the physical configuration of
the diplexer filter inside the environmental housing. The bandplans must be the same for the local and
remote TRACER 5045. For example, the transmitter at one end of the link will transmit in the lower
portion of the spectrum and receive in the upper portion. Consequently, the receiver at the other end should
receive in the lower portion and transmit in the upper portion.
The letter of the channel plan (A or B) must be different on both ends. Shipment of a link will consist of
one Plan A and Plan B unit.

TRACER 5045 System Manual
OVERVIEW
This troubleshooting guide provides recommended actions for various conditions of the TRACER 5045
system. The status LEDs (located on the front panel of the unit) provide information to help determine the
necessary troubleshooting action. Recommended actions for resolving possible status LED indicators are
contained in this guide.
2.
LED INDICATORS
PWR LED
If the PWR LED is not ON and solid green, it is an indicator that the TRACER 5045 is not receiving
adequate DC power.
Recommended Actions:
1. Verify that the power source is delivering between 21 and 60 VDC.
2. Check the polarity of the power connection (referenced to ground) of both the TRACER 5045 unit and
the power source.
3. Check the internal fuse. The fuse is accessed from the rear panel of the unit. If this fuse is open,
replace with a 1 A, 250 V (2-inch) slow-blo fuse.
TST LED
The TST LED will remain ON (solid amber) during power-up to indicate a self-test is in progress. If the
TST LED is blinking or remains ON after 10 seconds, this indicates that the TRACER 5045 unit has failed
the self-test. This is an internal failure, and ADTRAN technical support should be contacted.
RF DOWN LED
If the RF DOWN LED is ON (solid red), it is an indicator that there is a problem with the RF link to the
TRACER 5045.
Recommended Actions:
1. Check the RF coaxial cable connection.
2. Measure the RSSI voltage. If the signal is acceptable (> 2.0 VDC at RSSI test point), go to Step 6.
3. Verify that one end of the link is configured as Plan A and the other end as Plan B.
4. Verify that the antenna polarization is the same at both ends of the RF signal transmit and receive
path.
5. Verify the RF signal path is clear.
6. Check for possible interference at both ends of the link. If necessary, change polarization and/or
bandplans at both ends.
7. Check the integrity of the lightning arrestors.

Section 6 Troubleshooting Guide
RF LOW LED
If the RF LOW LED is ON (solid red), it is an indicator that the received signal is within 10 dB
(approximately) of the minimum operable signal. This condition is typically indicative of a path problem.
Recommended Actions:
1. Verify the far-end transmitter power setting is the value that the link planning budget allows.
2. Check all coaxial cable connectors for solid connections. Check for water and corrosion around any of
the connectors. If water is apparent in the coaxial connectors, replace the coaxial cable and the
connectors, making sure to properly weatherproof the replacements.
3. Verify the RF signal path by verifying the antenna alignment.
4. Check the integrity of the cable plant.
5. Check the integrity of lightning arrestors.
LAN LEDs
If the LAN LED is OFF, it is an indication that the TRACER 5045 does not detect an active ethernet link on
the particular 10/100BaseT/TX interface.
Recommended Actions:
1. Check all ethernet cable connections to verify they are properly plugged in (making sure the tab on the
connector snaps into place).
2. Connect the 10/100BaseT/TX interface to a “known good” ethernet port to verify the TRACER port is
functioning properly.
3. Try another ethernet cable.
3.
RF ERRORS
RF errors can range anywhere from a nonviable microwave path to loose RF connectors.
Nonviable path conditions could be caused by physical obstructions such as buildings, moutainous terrain,
trees, etc., as well as other physical limitations such as excessive path distances and in-band RF interference.
These types of errors are remedied by performing a detailed line-of-site microwave path study to determine
whether a microwave link is feasible for the terrain and environment under consideration.
If after performing a microwave path study the system is still not operational, ensure that the antennas are
properly aligned. Note that alignment must be achieved in both elevation and azimuth for optimal link
performance. The TRACER 5045 can be used to aid in antenna alignment by looking at the RX POWER “fuel
gauge” on the System Status or System Configuration menu pages. Optimal antenna alignment will
correspond to the maximum number of RSSI bars on the TRACER 5045 terminal display.
4.
STEP-BY-STEP TROUBLESHOOTING
The logical troubleshooting flow presented in this section can be used to set up your TRACER 5045 system,
and also to diagnose a previously installed system. Please contact ADTRAN Technical support at any stage
during installation and/or troubleshooting if you require assistance.

INSTALLING/TROUBLESHOOTING THE TRACER HARDWARE
1. Perform a detailed path profile and link budget for each TRACER 5045 microwave link. A
thorough path study can be used to estimate signal power budgets, fade margins at each receiver,
identity potential line-of-site obstacles, properly size antenna dishes, and determine minimum
antenna dish heights above the earth.
ADTRAN provides a wireless link planning tool on our website. This link budget tool is
constructed as an easy to use spreadsheet with dropdown menus so that the user can
quickly change any of the link parameters (antenna size, coaxial cable type and length,
frequency band, link distance, etc) and instantly see how the microwave path availability is
affected. This tool is available at www.adtran.com/wireless and can be used online or
downloaded for standalone use.
2. Setup all of the TRACER hardware on a workbench. ADTRAN recommends that the actual cables
used in the permanent installation be used in the workbench setup. A rigorous workbench
“simulation” of the link will help alleviate and avoid time-consuming errors.
3. Examine the PLAN A and PLAN B LEDs on the front panel of each unit. These LEDs indicate the
frequency plan for each TRACER 5045 unit. The frequency plan (Plan A, Plan B) LED should be
the opposite on the TRACER 5045 units.
4. Attach the RF coaxial cables to be used in the permanent installation to the N-type connectors on
the back of the TRACER 5045 unit. Attach the other end of the coaxial cable(s) to an RF power
meter or spectrum analyzer, if either is available. The power measured by the meter/analyzer will
be the RF power available at the input of the antenna. The TRACER 5045 unit is programmed at
the factory to output approximately 100 mW (20 dBm) of RF power. The actual power level
measured by the meter/analyzer will be less than 100 mW due to RF losses through the coaxial
cable, and is a function of the cable type and length being used. In any event, the power level at the
output of the coaxial cable should be a significant fraction of 100 mW. A power meter/analyzer
reading that is not on the order of at least tens-of-milliwatts could be an indication of any
combination of either unsuitable RF, faulty, or unreasonably long coaxial cable.
5. Resolve all RF coaxial cabling errors before proceeding.
6. Attach the RF coaxial cables to a high-quality attenuator, if possible. If you do not have an
attenuator, attach the coaxial cables to the antennas to be used in the permanent installation. If the
installation antennas are not available, small, inexpensive dipole or patch antennas can be used for
verification purposes. If an adjustable attenuator is being used, dial in the amount of attenuation
that corresponds to the path loss value expected for the microwave link in which the TRACER
hardware will be installed. The path loss value can be calculated from a knowledge of the path
length, or provided by a path study. Remember to subtract both antenna gain values from the
attenuator level if these values have not already be accounted for.
7. After setting up the RF pieces, examine the RF DOWN LED on the front panel of each TRACER
5045 unit. If the RF DOWN LED is illuminated (red), the corresponding TRACER 5045 is not
receiving a suitable RF signal from the other TRACER 5045 unit. In this case, the receiving
TRACER 5045 is either receiving a very weak signal, or no signal at all. If the RF DOWN LED is
not illuminated, then the TRACER 5045 units are receiving a suitable RF signal. Suitable RF
power levels for low error rate communication will range from -30 dBm to -78 dBm measured at
the N-type connector input on the TRACER 5045 unit.
8. Resolve any signal level issues before proceeding.

9. Examine the RF LOW LED on the front panel of each TRACER 5045. If this LED is illuminated,
then the TRACER 5045 is receiving a relatively weak signal; however, if the RF DOWN LED is
not illuminated, then the received signal is being suitably processed by the TRACER 5045 system.
If you are receiving a weak signal (RF LOW is ON), please verify that the weak signal is not being
caused by a faulty cable, an insufficiently tightened cable, or some other installation-related
problem. Also, make sure an unreasonably large attenuation value has not been selected if you are
using an attenuator on a workbench setup.
Use the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the
proper free-space attenuation value (in dB) based on the estimated length of the microwave path.
Remember to subtract both antenna gains (local and remote) from the attenuator setting.
10. Command a link loopback in one TRACER 5045 unit and run a test pattern from the connected T1
equipment. This will verify the data path between the T1 equipment and the TRACER 5045 unit.
External pattern generators are required to test data path integrity. A T1 BERT tester is
suggested.
Installing/Configuring T1 Hardware
1. If possible, attach any or all of the intended T1 hardware to the TRACER 5045 units using the
same workbench setup. This step offers the perfect opportunity to configure your T1 hardware for
proper functioning with the TRACER hardware.
2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining
T1 equipment-to-TRACER 5045 configuration issues before field installation.
