Radiation Warnings
Microwave Radio Radiation Warning
Under normal operating conditions, N2limits for human exposure to radio frequency (RF) fields adopted by the Federal Communications Commission (FCC). All Wireless, Inc. microwave radio equipment is designed so that
under normal working conditions, microwave radiation directly from the radio is negligible when
compared with the permissible limit of continuous daily exposure recommended in the United
States by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure to
Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

Microwave signal levels that give rise to hazardous radiation levels can exist within transmitter

Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation.
Do not disconnect RF coaxial connectors, open microwave units, or break down any
microwave screening while the radio equipment is operating.

N2-X Ethernet Extender Installation and Operation Manual
Microwave Antenna Radiation Warning
Designed for point-to-point operation, an N2-
X Ethernet Extender
microwave radio system will
use directional antennas to transmit and receive microwave signals. These directional antennas are usually circular or rectangular in shape, are generally located outdoors, and are usually
mounted on a tower or mast.
Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal Communication
Commission’s Office of Engineering & Technology, limits for maximum permissible exposure
(MPE) to microwave signals have been adopted by the FCC for both Occupational/Controlled
environments and General Population/Uncontrolled environments. These limits are 5.0 mW/
cm2 and 1.0 mW/cm2, respectively, with averaging times of six-minutes and thirty-minutes,
respectively.
The closer you are to the front center-point of a microwave antenna, the greater the power
density of its transmitted microwave signal. Unless you are very close, however, microwave
exposure levels will fall far below the MPE limits. To determine how close to a microwave
antenna you can be and still remain below the MPE limits noted above, “worst case” predictions
of the field strength and power density levels in the vicinity of an N2-
X Ethernet Extender
TM
microwave antenna can be made from the following calculations. The equation is generally
accurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e.
close to the antenna).
S = PG/4πR
2
where: S = power density (in mW/cm2)
P = power input to the antenna (mW)
G = power gain of the antenna in the direction of interest relative to an isotropic
radiator
R = distance to the center of radiation of the antenna (cm)
Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and must
be converted using the following equation:
G = 10
dB/10
For example, a logarithmic power gain of 24 dB is equal to a numeric gain of 251.19.
Assuming (1) maximum output power from the N2-
(2) no signal loss in the cable connecting the N2-

(+3.5 dBm [2.238 mW]),
to the antenna, and (3)
the use of a 27 dBi gain parabolic antenna, the 5.0 mW/cm2 and 1.0 mW/cm2 MPE power density
limits would be reached at distances of approximately 4.22 cm and 9.44 cm, respectively.
Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnel
maintain appropriate distances from the front of all directional microwave antennas. Should you

1.0 General Overview
1.1 N2-ACCESS Series Product Family
All N2-X Ethernet Extender radios are members of the N2-ACCESS Series radio product family.
The N2- ACCESS Series is designed to provide an economical wireless solution for local
access telecommunication requirements.
The N2-ACCESS Series radio product family consists of several product offerings, to include
both the N2-ACCESS Link. This manual addresses, in detail, the operation of the N2-X Ethernet
Extender. For detailed information on other N2-X Ethernet Extender radios or other members
of the N2-ACCESS Series, please refer to the appropriate Operation Manual(s).
1.2 Introduction to the N2-X Ethernet Extender
The N2-X Ethernet Extender series of radios are designed for operation in two of the Unlicensed
National Infrastructure at frequencies of 5,250 - 5,350 MHz or 5,725 - 5,825 MHz.
Each N2-X Ethernet Extender is comprised of a pole mounted RF/antenna unit. Each link is
powered by means of a AC wall transformer (optional DC powering available) located with the
indoor terminal unit. The system has a data transmission capacity of 16 Mb/s. Refer to the N2X Ethernet Extender data sheets for information relating to product offerings and specifications.

N2-X Ethernet Extender Installation and Operation Manual
1.3 Regulatory Information
In January 1997, the FCC made available 300 MHz of spectrum for Unlicensed National
Information Infrastructure (U-NII) devices. The FCC believes that the creation of the U-NII band
will stimulate the development of new unlicensed digital products which will provide efficient and
less expensive solutions for local access applications.
The U-NII band is divided into three sub bands at 5.15 - 5.25, 5.25 - 5.35 and 5.725 - 5.825 GHz.
The first band is strictly allocated for indoor use and is consistent with the European High
Performance Local Area Network (HIPERLAN). The second and third bands are intended for
high speed digital local access products for “campus” and “short haul” microwave applications.

2.0 N2-X Ethernet Extender Product Profile
2.1 General Overview
The N2-X Ethernet Extender series of microwave radio products provides digital capacities for
16 Mb/s data rates for short-haul applications up to 10 km. The radio terminal operates in the
newly allocated Unlicensed National Information Infrastructure (U-NII) spectrum with a revolutionary Split Modulation system architecture that provides full duplex operation in the 5.3/5.7
GHz U-NII frequency bands.
The N2-X Ethernet Extender series provides the unique advantage of a very robust digital
transmission scheme.
Split Modulation uses two separate 100 MHz bands within the U-NII frequency spectrum. Within
these bands, the N2-X Ethernet Extender series operates in one of many independent channels
providing for frequency reuse and network flexibility, ideal for dense network applications.
Synthesized RF channel selection is field configurable, as are the power output options for the
selection of antenna sizes. Frequency coordination and installation guidelines are provided in
the appendix section of this manual.
Complying with all aspects of FCC Rules Subpart 15.401-15.407, the transmission characteristics of the N2-X Ethernet Extender series are ideally suited to meet the peak power spectral
density requirements of the U-NII 5.250 - 5.350 and 5.725 - 5.825 GHz bands.
Note: From this point on in this Operations Manual, unless specified otherwise, the term N2-
X Ethernet Extender refers to the 5.3/5.7 GHz N2-X Ethernet Extender radio.
The N2-X Ethernet Extender as been designed for complete front access to all interfaces,
controls and displays. Information in this manual will familiarize you with all of these items.

2.6 Theory of Operation
2.6.1 N2-X Ethernet Extender Transmitter
This description should be used in conjunction with the system block diagram Figure 2.4.
The data signal and the AC/DC supply voltage are connected to the ODU by means of a
power/data cable assembly. The supply voltage passes through a bridge rectifier to a DC
to DC converter. The output of this converter is +15V. This +15V supply drives three DC
regulators within the ODU.
One regulator provides -5 VDC, the second 11 VDC and the third being a dual output type
supplies +5 and +5.8 volts.
The FPGA coder interleaves and scrambles the TTL data from the coder. The FPGA is
programmed to output the data at 4 times the input rate (6.176 MHz for the DS1 rate or
8.192 MHz for E1 rates). This provides a data rate which is optimal with respect to the FCC
rules for spectral power densities defined for this frequency allocation.
The data is passed through a 7th order low pass filter to reduce unwanted high frequency
signal images prior to modulation. A double balanced mixer is used to modulate the data
signal on to a CW signal provided by the synthesizer at the desired output frequency. The
output of the mixer contains the BPSK modulated signal at the desired frequency.
A high pass filter eliminates spurious noise, rejects harmonic images and insures that the
proper bandwidth is maintained prior to being amplified.
The RF output section consists of three main components: a RF driver amplifier, a logic
controlled switch attenuator and a RF power amplifier. The driver amplifier provides the first
stage of RF amplification, the switch attenuator serves a dual purpose. The first is to
provide a customer selectable 6 dB attenuator to reduce output power when needed.
Secondly, this circuit acts as an RF impedance matching network between the driver and
power amplifier gain stages. The power amplifier provides the amplification required prior
to being output through a diplexing filter and ultimately to the antenna.

2.6.2 N2-X Ethernet Extender Receiver
The description should be used in conjunction with the system block diagram (Figure 2.4).
At the antenna, the received BPSK modulated signal from the opposite terminal is passed
through a diplexing filter which is used to isolate the incoming signal from the transmitter output
and to bandpass filter the received signal thereby reducing the chance of unwanted signal
products from entering the receiver. A low noise amplifier (LNA) detects and amplifies the signal
bandpass filter on the output of the LNA provides band limiting of the received spectrum to reject
unwanted signal products. The first downconverter combines a CW signal at the receiver
frequency from the synthesizer and the incoming signal by means of a mixer to produce the first
IF product at 474.880 MHz. A 75 MHz bandpass filter limits the possibility of unwanted out of
band products from entering the 2nd IF. The first IF is amplified by a MMIC device and is
downconverted by mixer a 389.76 MHz signal from the synthesizer with the 474.880 MHz 1st
IF signal. The result is a 85.12 MHz 2nd IF product which is bandpass filtered and fed to an RSSI
IF processing DC which derives an RSSI voltage used to determine signal strength.
A BPSK demodulator places the 85.12 MHz 2nd IF and 85.12 MHz varactor diode source out
of phase. The resultant product is a DC level I and Q signal of which only the I signal is input
to the Bit Synchronizer to re-clock the data. The re-clocked data is decoded and output at TTL
level to the DS1/E1 level converter which outputs the data in AMI, B8ZS or HDB3 format as
needed. The data is interconnected to the TU and output on the front panel by means of RJ48C or BNC connector depending on the data format being used.
2.6.3 Synthesizer
The FPGA provides four 22-bit streams in a serial format loaded to the synthesizer. This data
provides all of the possible frequencies at which the system can operate. Depending upon the
dip switch settings selected, the actual frequency being used is selected. When the reset button
is pressed, the FPGA will reload this data to the synthesizer. The PROM contains all of the
possible frequency combinations.

3.5.1 Configuring N2-X Ethernet Extender System Antennas
The antennas used on an N2-X Ethernet Extender radio system are generally configurable for
either vertical or horizontal polarization. It is extremely important to verify that both antennas
are configured for the same polarization, and that the appropriate antenna polarization has
been selected for the specific radio link.

N2-X Ethernet Extender Installation and Operation Manual
3.5.2 Aligning the N2-X Ethernet Extender System Antennas
With the N2-X Ethernet Extender at each site properly configured for operation, antenna
alignment must be performed at both sites. Proper antenna alignment is crucial to the proper
operation of an N2-X Ethernet Extender radio system, and should only be accomplished by
experienced professionals.
The N2-X Ethernet Extender is equipped with a ODU mounted BNC-(f) Link Test connector to
which an analog or digital voltmeter can be connected. The voltage range at the test point,
between the center conductor of the connector and ground, varies from approximately two VDC
to four VDC, serving as a receive signal strength indicator (RSSI). The stronger the receive
signal, the higher the RSSI voltage.
Emanating from a microwave antenna is a main beam (or lobe) of RF energy, surrounded by
RF side lobes. The beamwidth of the main beam varies with the size and type of antenna, as
well as the specific frequency of the RF signal, and is generally defined by the nominal total width
of the main beam at the half-power (-3 dB) points. Side lobes surround the main beam at specific
angle distances, and will be lower in power than the main beam.
When aligning an antenna system, it is extremely important to verify that the antennas are both
aligned on the main beam, not on a side lobe. Referencing Table 3.3, the first side lobe will
generally be located at an angle slightly less than twice the antenna beamwidth.
Following the course alignment of an antenna system, a common practice when performing a
fine alignment is to slowly swing each antenna (one at a time!) in both vertical (elevation) and
horizontal (azimuth) planes to verify that the main beam and first side lobe can be accurately
identified. This insures that accurate alignment of the antenna system on the main beam has
been accomplished.
Each N2-X Ethernet Extender is shipped with an RSSI test sheet, showing the relationship
between the receive signal strength level (in dBm) and the RSSI level (in VDC). These RSSI
test sheets are often referred to as AGC Curves. The RSSI test sheets can be used to verify
that the calculated receive signal levels match up with the actual receive signal levels.
Substantial differences between calculated and actual levels could point to transmission
system problems, side lobe alignment, path obstructions, etc.

4.0 Maintenance and Troubleshooting
The N2-X Ethernet Extender contains static sensitive components, and has no user-serviceable parts.
4.1 N2-X Ethernet Extender Maintenance
The N2-X Ethernet Extender is designed to operate with no scheduled maintenance activities.
From a precautionary perspective, a regular check of power supply input voltages and RSSI
voltages should be planned by the user.
4.1.1 RSSI Voltage
The Wireless Customer Service department recommends a monthly check of the N2-X
Ethernet Extender’s RSSI voltage. Variations in the RSSI voltage could be an indicator of
antenna or antenna feed movement, loose or improper RF cabling or connectorization, path
obstructions or reflections, etc.

N2-X Ethernet Extender Installation and Operation Manual
4.2 Identifying and Resolving Receive Signal Strength Issues
There are a great number of items which can affect the transmission of a microwave signal from
one site to another. Every microwave path is unique, and must be evaluated for performance
before a radio link is installed.
Outside of radio equipment issues, antenna alignment, RF signal blockage, and multipath
fading are among the most common transmission problems experienced in the field.
4.2.1 N2-X Ethernet Extender Equipment Issues
Frequency Selection
1. Verify the transmit/receive frequency selection for each N2-X Ethernet Extender radio is
set appropriately, and that a “matched pair” of radios has been selected for the system.
Each N2-X Ethernet Extender terminal can be set to the frequencies listed in Table 4.1.
2. To reduce the possibility of co -adjacent channel interference, proper frequency coordination and antenna polarization is used to isolate each channel. The concept is to achieve
maximum RF isolation between link channels by means of frequency spacing and antenna
polarization. In a “star” configuration an optimum frequency and antenna polarization plan
is provided to demonstrate an example of maximum isolation between links (See Figure
4.1).

4.3 N2-X Ethernet Extender Digital Board Switch Settings
There are two versions of the N2-X Ethernet Extender Digital Board. Before making switch
changes, verify the version of the Digital Board in use. In a working system, the East Radio might
be equipped with Version one while the West Radio might be equipped with Version two. The
specific version of a N2-X Ethernet Extender’s Digital Board will have no effect on the operation
of a radio system.
In addition to there being two versions of the Digital Board, there are also two types of Digital
Boards: a X Mb/s type and a X Mb/s type. Each type of Digital Board contains different
components.

Unpacking and Preparation
1. Carefully unpack the reflector, mount, shroud (if any), radome (if any) and feed from the
crate. For correct antenna performance, handle all components with care. Set aside the
packaged feed and any shroud or radome. See Figures B.3 through B.6.
Caution: The reflector spinning has been formed to a very close-toleranced parabolic shape.
Careful handling and assembly is required to avoid denting or deforming the reflector,
which would degrade the antenna's performance.
2. Inspect for any damaged parts. See Tables B.2a-B.2d for an inventory of the parts and
hardware shipped with the antenna.
Shroud Attachment
Attach the shroud assembly that is provided with high-performance antennas to the reflector.
The installation procedure is covered by another instruction sheet supplied with the shroud.
Note: Some models have the shroud factory installed.

Mount Assembly and Attachment
1. The reflector should be placed face down, either on the shroud or blocked up on packing
lumber. Locate the Top and Bottom markings stenciled onto the back of the reflector.
2. Loosely attach Top Support Angles to the Horizontal Tube Assembly as shown in Figure
B.7 and B.8.
3. For desired mount configuration (refer to Figure B.2), attach the Vertical Tube Assembly
to the Horizontal Tube Assembly as shown in Figure B.7 and B.8.
4. Verify proper assembly of the elevation rod hardware as shown in Figure B.9. Remove
outer hardware and insert rod through elevation plate.
Important: For elevation angles grater than ±20°, Beveled Washers, shown in Figure B.9,
must be used. However, beveled washers may be used for elevation angles greater than
±10°.
5. Carefully place mount assembly onto antenna backring, taking care not to damage the
reflector. Loosely fasten the Top Support Angles and the Elevation Support Angle to the
antenna backring using 1/2” hardware as shown in Figure B.7.
6. Verify alignment of the Vertical Assembly with the vertical axis of the reflector and secure
the Top Support Angles and the Elevation Support Angle to the ring.

Molded Radomes (normally optional on standard antennas) should be installed following the
instructions provided.
Azimuth Adjustment Clamp/Shear Stop Installation
1. Verify proper assembly of the azimuth clamp/shear stop clamp as shown in Figure B.15
and B.16. Securely attach the shear stop clamp to the mast pipe as shown, orienting it as
nearly as possible to the antenna boresight direction, and square to the mast axis. Note
that the shear stop clamp used on the two foot antennas also provides the azimuth
adjustment.
2. Refer to Figure B.1 for the position of the antenna centerline relative to the shear stop
clamp. The clamp must be mounted to provide support during installation and azimuth
adjustment.

Antenna Hoisting and Installation
1. Attach a hoist strap around the vertical assembly or the horizontal assembly as shown in
Figure B.17. Do not hoist by the elevation rod. Make sure that the vertical assembly is
unobstructed where it will mount against the mast pipe.
2. Attach tag lines and carefully lift the antenna into position, resting the vertical assembly on
the shear stop clamp.
3. Fasten the mount to the mast pipe with 1/2” U-bolts. The antenna must be free to rotate
during azimuth adjustment, so tighten only enough to close the gap between the mast and
vertical channel. Do not leave the antenna loose for any extended period of time, i.e.
overnight.

General Antenna Alignment Procedures
Normally the antenna is aligned by performing azimuth and elevation adjustments and
elevation adjustments as necessary until the peak signal is obtained. It may be helpful to repeak one adjustment before finalizing or locking down the other. See Figure B.18.
Warning: Damage to the antenna can occur if azimuth or elevation adjustments are
attempted without loosening the proper connections as described in the following steps.
Azimuth Adjustment
1. Be sure the mast pipe U-bolts are just loose enough to allow mount rotation while
maintaining complete contact between the mount and the mast pipe.
2. Turn the long stainless steel azimuth screws against the mounting channel. By alternately
turning one azimuth adjustment screw out and the other in, the antenna can be rotated to
the desired azimuth angle. Approximately 1 turn changes the azimuth direction by 1°. Avoid
adjusting the antenna beyond the ±5° provided by the azimuth clamp as this can damage
the adjusting hardware. Fasten the antenna to the mast pipe and reposition the clamp if
needed.
Note: By securing the mount to the mast pipe and realigning the azimuth clamp with the
antenna boresight, more reliable and precise azimuth adjustments can be achieved.
After all adjustments are made, tighten both of the azimuth screws against the channel and
secure with the lock nuts provided.
3. Tighten the mast pipe U-bolts while maintaining the peak signal by alternating from left to
right in 1/4 turn intervals.

B-16
WL035949
Elevation Adjustment
1. Insure that both of the bolts connecting the mount to the Top Support Angles and the
pivoting Elevation Angle (refer to Figures B.7 and B.9) are just loose enough to allow
resisted rotation. See Figure B.18.
2. Back the outer nuts on the elevation rod away from the bottom mount plate to allow some
fine adjustment range.
3. Turn the inside nut (with flat washer) on the elevation rod to adjust the elevation angle.
Approximately 5 turns changes the elevation by 1°. Remember, for elevation greater than
20°, install the two beveled washers as shown in Figure B.9.
4. After all adjustments are made, lock the nut against the bottom mount plate. Tighten the
angle pivot bolt and support bracket bolts.
Important: Be sure to tighten all hardware after final adjustments and insure that split
lockwashers, palnuts, or jam nuts are used where provided.

Inspection and Maintenance
1. Before leaving the installation, check that all hardware on the mount, shroud, radome, and
feed is tight and that nuts are locked in place.
2. Inspection of the antenna should be performed at lease once a year to check its condition
and to insure safe operation and maintenance. Qualified personnel, knowledgeable and
experienced in antenna installations, are required for this inspection.
Supplemental Information
Table B.3 is provided for installers unfamiliar with adequate nut tightening procedures for use
on stainless steel bolts, U-bolts, galvanized bolts or any bolts without the ASTM-”A325” marking
on the head. Disregard these recommendations when specific tightening requirements are
given.
Note: It is not recommended to reuse a palnut that has already been fully tightened or
deformed in any way. It should be replaced by a new palnut.
Weather Proofing the Type N Female Connector on Feeds
Remove the protective cover from the end of the feed and mate the connectors, screwing the
male connector firmly onto the feed.
Important: After connecting the coaxial cable, wrap the Type N connector with the gray butyl
rubber, squeezing it firmly around all joints to make a continuous seal. Finish the
weatherproofing by wrapping the butyl rubber with several layers of black PVC tape (not
supplied).

Attach the antenna to the mount as shown in Figure C.4. For antenna polarization, assemble
the antenna to the mount using four sets of nuts and washers after desired polarization is
selected. In horizontal polarization the arrow sticker should be pointed in a horizontal direction.
Likewise, in vertical polarization the arrow sticker should be pointed in a vertical position.
Important: After cable connection is completed, wrap connection with Butyl or other
waterproof tape, supplied by the customer.
Each panel antenna has four factory sealed drain holes located on the back of the antenna. After
orienting the antenna to its proper polarization, the lower most sealed drain hole(s) must be
punctured with a pointed tool. See Figure C.4.
Caution: Do not allow the tool to protrude into the drain hole more than 1/4” (7mm) or damage
to the antenna may result.
