Site Preparation
Planning the Link Site
Overview
Link site planning consists of a set of surveys, which must be carried out
before any equipment is brought to the site. If for some reason, the out-
come of any of these surveys is negative, site re-location will need to be
considered.
A Site Survey consists of three stages:
1. Preliminary survey - The proposed link is analyzed in the office using a
topographic map.
2. Physical survey - The locations of the RADWIN 1000/2000 indoor and
outdoor equipment are determined on-site.
3. Radio Frequency (RF) survey - It is recommended that the installation
area be scanned with a spectrum analyzer, to identify RF interference so
as to determine a clear channel for RADWIN 1000/2000 installation (on-
site).
The Site Survey
Introduction
RADWIN 1000/2000 wireless links must be planned before installation. The
designated installation site must be appraised to determine that the wire-
less system is able to operate efficiently and provide connectivity without
signal degradation.
RADWIN 1000/2000 offers a wide operating frequency range. A free fre-
quency channel must be determined within the operating range, for opti-
mum performance.
Recommended Equipment
Stage 1: Preliminary Survey
• Topological map of the area
Stage 1: Preliminary Survey Chapter 2
RADWIN 1000/2000 User Manual Version 2.12 2-2
• Urban map of the area
•Compass
Stage 2: Physical Survey
• 100 meter tape measure
• Ohmmeter, to check ground connection
•Binoculars
•Map
• Digital camera
• Paper, pencil, and a clipboard
• GPS device (optional)
• Compass (optional)
Stage 3: RF Survey
• Spectrum Analyzer with Max Hold function and screen capture facil-
ity that can store multiple images, for documentation purposes
• RF accessories (connectors and cables)
• Communication devices (for example, cellular phones, or a set of
walkie-talkies)
Stage 1: Preliminary Survey
A preliminary survey is necessary before visiting potential installation sites.
As much detail as possible should be obtained about the two designated
ODU installation sites and the area between them.
¾To perform a preliminary survey:
1. Mark the two designated installation sites on a topographic map of the
area.
2. Measure the distance between the sites; check that it is within the speci-
fied range of the RADWIN 1000/2000.
3. On the urban map, check for developed areas situated between the two
installation sites. Pay attention to these areas when performing the phys-
ical site survey; there may be tall buildings, RF towers, or transmitters,
which could cause interference to the link.
4. Check the area between the two sites for obstructions such as:
• High ground - hills or mountains
• Lakes or large bodies of water. Water has a reflection effect on RF
signals like a building. This type of reflection causes the received
amplitude to be reduced. As a rule of thumb, the presence of a large
body of water between the link sites may double the required
antenna height.
5. Determine and record the compass bearings between both ODUs, rela-
tive to north.
6. If there are obstructions between the two sites, calculate the Fresnel
Zone (see appendix D for details).
Stage 2: Physical Survey Chapter 2
RADWIN 1000/2000 User Manual Version 2.12 2-3
7. If the site chosen does not meet requirements, consider alternative sites.
8. Use the Link Budget Calculator (on the CD supplied with the RADWIN
1000/2000 or using the RADWIN Manager) to determine the expected
performance.
Stage 2: Physical Survey
The physical site survey reviews the environment of the proposed RADWIN
1000/2000 installation location, to ensure that the link sites are suitable for
the wireless network. The results of the physical site survey should be
recorded.
¾To perform a physical survey:
1. From the compass readings taken in the preliminary survey, find the azi-
muth (horizontal position) that the ODU should face towards the second
ODU.
2. Using binoculars, locate any obstructions such as tall trees, high build-
ings, hills or mountains. Look for other RF towers between the two sites.
Mark the locations of the obstructions on the map.
3. Determine the location for the ODU (having regard for existing rooftop
installations and tower space). It should be above any obstructions, con-
sidering the Fresnel zone (see appendix D).
4. If you need to install the ODU on a tower, make sure that the tower is far
away from overhead electric power lines.
5. Determine a location for the indoor equipment; it should be as close as
possible to the ODU. At an existing site, there is probably an equipment
room with cable-routing channels.
6. Measure and record the path length of the cable from the ODU position
to the indoor equipment room.
7. Determine the ground and lightning connection points of the installation.
The RADWIN 1000/2000 ODU and IDU must both be grounded.
8. Using the Ohmmeter, measure and record the resistance of the required
installation to the grounding point. The resistance must be less than 1O
ohm.
Note
It is advisable to go on a clear day, so you can more easily see any
obstructions between the two sites.
Note
The IDU - ODU cable length limit is 100m, in accordance with IEEE 10/
100BaseT standards.
Additional Outdoor Site Requirements Chapter 2
RADWIN 1000/2000 User Manual Version 2.12 2-4
9. Review the results of the physical site survey. Decide if the site is suitable
for the RADWIN 1000/2000 wireless network installation.
• If the site is suitable, continue with stage 3, the RF survey
• If the site is not suitable, survey another site
Additional Outdoor Site Requirements
The ambient outdoor operating temperature should be -35 to 60°C (-31 to
140°F).
Additional Indoor Site Requirements
The following requirements guarantee proper operation of the system:
• For IDU-C units, allow at least 90 cm (36 “) of front clearance for
operating and maintenance accessibility. Allow at least 10 cm (4 “)
clearance at the rear of the unit for signal lines and interface cables
• The ambient operating temperature should be 0 to 50°C (32 to 122
°F) at a humidity of up to 90%, non condensing
Stage 3: RF Survey
The RF survey examines the wireless environment of the RADWIN 1000/
2000 installation site, to determine whether there are available channels
within the RADWIN 1000/2000 operating frequency band. An RF survey is
performed using a spectrum analyzer.
It is advisable to familiarize yourself with the spectrum analyzer before
going out on site, specifically the Max Hold and Marker functions.
You should perform the RF survey at both proposed link sites.
The survey should be carried out during a busy time of day, to best judge
the worst-case radio interference. Allow 2-4 hours duration for a good RF
survey.
Note
It is possible to install the RADWIN 1000/2000 link and use the RADWIN
Manager to find a clear channel. Each frequency channel can be evaluated
in turn. Achievement of a clear channel is indicated by the Quality bar on
the Channel Setting window (see figure 4-13) becoming green.

Chapter 3
Hardware Installation
This chapter sets out the requirements and procedures for the hardware
installation and alignment of a RADWIN 1000/2000 link in accordance with
the prior planning as set out in chapter 2. It is intended to guide qualified
field technicians.
Safety Practices
Preventing overexposure to RF energy
To protect against overexposure to RF energy, install the ODUs so as to pro-
vide and maintain minimal separation distances from all persons.
When the system is operational, avoid standing directly in front of the
antenna. Strong RF fields are present when the transmitter is on. The ODU
must not be deployed in a location where it is possible for people to stand
or walk inadvertently in front of the antenna.
Grounding
All RADWIN products should be grounded during operation. In addition:
•The ODU should be earthed by a wire with diameter of at least
12AWG.
The RADWIN 1000/2000 ODU must be properly grounded to protect
against lightning. It is the user's responsibility to install the equip-
ment in accordance with Section 810 of the National Electric Code,
ANSI/NFPA No.70-1984 or Section 54 of the Canadian Electrical
Code. These codes describe correct installation procedures for
grounding the outdoor unit, mast, lead-in wire and discharge unit. It
Warning
Outdoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate
government regulatory authorities. Failure to do so may expose the end
user or the service provider to legal and financial liabilities. RADWIN and its
resellers or distributors are not liable for injury, damage or violation of
regulations associated with the installation of outdoor units or antennas.
Protection against Lightning Chapter 3
RADWIN 1000/2000 User Manual Version 2.12 3-2
also lays down the size of grounding conductors and connection
requirements for grounding electrodes.
The RADWIN 1000/2000 ODU must be grounded to a Protective
Earth as described in appendix E and in accordance with the Local
Electrical Regulations.
• The earth lug on the IDU-C should be connected to the protective
earth at all times, by a wire with a diameter of 18 AWG or wider.
Rack-mounted equipment should be mounted only in earthed racks
and cabinets.
Further, you should -
• Always make the ground connection first and disconnect it last
• Never connect telecommunication cables to ungrounded equipment
• Ensure that all other cables are disconnected before disconnecting
the ground
More detailed guidelines are supplied in appendix E.
Protection against Lightning
The use of lightning protection is dependent on regulatory and end user
requirements. All of RADWIN outdoor units are designed with surge limiting
circuits to minimize the risk of damage due to lightning strikes. RADWIN
recommends the use of additional surge arrestor devices to protect the
equipment from nearby lightning strikes.
See appendix E for detailed installation instructions of lightning protection
devices.
General
• It is recommended that installation of the outdoor unit be contracted
to a professional installer.
• Before working on equipment connected to power lines or telecom-
munication lines, you should remove jewelry or any other metallic
object that may come into contact with energized parts.
• Use extreme care when installing antennas near power lines.
• Use extreme care when working at heights.
• When using an AC power source for RADWIN 1000/2000 always use
the AC power adapter supplied by RADWIN.
• Use the right tools. In addition to standard tools required for any

Connecting power to the IDU Chapter 3
RADWIN 1000/2000 User Manual Version 2.12 3-11
Connecting power to the IDU
The IDU-C has redundant power connection circuits (items G and H in
figure 3-7 above). An enlarged schematic of the power connectors is
shown in below:
Figure 3-10: DU-C ower connectors
The connectors are 3 pin in line female, with polarities (left to right) minus,
ground, plus. To avoid damage to the IDU, always use an AC/DC adapter
supplied by RADWIN.
Ensure that the IDUs at both sites are powered up.
Connecting the ODU to the IDU
The ODU-IDU cable conducts all the user traffic between the IDU and the
ODU, and also provides power to the ODU. The maximum length of the
ODU-IDU cable is 100m (328 ') in accordance with 10/100BaseT standards.
The ODU-IDU cable is supplied pre-assembled with RJ-45 connectors, at the
length specified when ordering, or as a cable drum with spare connectors. If
the ODU-IDU cable was not ordered, use an outdoor class, CAT-5e 24AWG
shielded cable. See appendix B for Wiring Specifications.
To connect the ODU to the IDU, route the cable from the ODU to the IDU,
secure the cable along its path and connect the cable to the ODU RJ-45
connector on the IDU (see item B in figure 3-7 above).
Installing a Link using PoE Devices
The PoE device is a very simple unit having a power input connector and
two Ethernet ports. It is AC powered, and has a power LED.
¾To prepare a link using PoE devices:
1. To connect the ODU to the PoE device, route the cable from the ODU to
the PoE device, secure the cable along its path and connect the cable to
the P-LAN-OUT RJ-45 connector on the PoE device.
2. Connect it to AC power.
3. Repeat steps 1 to 2 for the second link.
Connecting User Equipment Chapter 3
RADWIN 1000/2000 User Manual Version 2.12 3-12
Connecting User Equipment
¾To connect user equipment to the IDU:
• Connect user switch/router or any other compatible device to the IDU
panel RJ-45 ports designated LAN (see item C in figure 3-7 above).
Refer to appendix B, Wiring Specifications, for connector pinouts.
¾To connect user equipment to the PoE device:
• Connect a user switch, router or any other compatible device to the PoE
device RJ-45 port designated LAN-IN. Refer to appendix B, Wiring
Specifications, for connector pinouts.
Connecting and Aligning ODUs / Antennas
You perform antenna alignment using the ODU's audible tone.
To speed up the installation time, alignment of a RADWIN 1000/2000 sys-
tem should be performed by two teams simultaneously, at site A and at site
B.
¾To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connec-
tors, connect the vertical polarization connector of the antenna to the
ANT 1 connector of the ODU.
2. For external bipolar antennas: Using a coax cable with N-Type connec-
tors, connect the horizontal polarization connector of the antenna to the
ANT 2 connector of the ODU.
3. Ensure that power is connected to the IDUs at both sites.
4. Ensure normal operation of the IDUs by the LED indications on the front
panel.
Provided that site A detects the signal from site B, the ODU starts beep-
ing 20 seconds after power up, and continues beeping until the ODUs are
aligned, and the installation is complete.
In the following steps, “antenna” refers both to an external antenna and
an integrated antenna.
5. Direct the antenna of site B in the direction of site A. This is simplified if
a previous site survey has been completed and azimuths are known.
Note
Do not connect two LAN ports to the same network, or flooding may occur.
Warning
When aligning the antennas, do not stand in front of a live antenna.
Connecting and Aligning ODUs / Antennas Chapter 3
RADWIN 1000/2000 User Manual Version 2.12 3-13
6. Make a horizontal sweep of 180 degrees with the site A antenna so that
the strongest signal from site B can be detected.
7. Slowly turn the site A antenna back towards the position of site B, listen-
ing to the tone until the best signal is reached. See the following figure
for audible signal variations.
Figure 3-11: Beep Sequence for antenna alignment
8. Secure the site A antenna to the pole/wall.
9. Repeat steps 4 to 8 for site B.
¾To align two external monopolar antennas:
1. Using a coax cable with N-Type connectors, connect one antenna to the
ANT 1 connector of the ODU.
2. Follow the steps 3 to 7 above to align the antenna connected to the ODU
connector ANT 1 on both sides of the link.
3. On both sides of the link, disconnect the antenna connected to the ODU
connector ANT 1. Connect the other antenna to connector ANT 1 and fol-
low the steps 3 to 7 above to align the second antenna.
4. Secure the antennas to the pole/wall.
5. Restore one of the antennas to ANT 2 on both sides of the link.
Note
• Three beeps and a pause is 'best signal so far'
• Two beeps and a pause is 'signal quality increased'
• One beep and pause is 'no change in signal'
• Long beep and short pause is 'signal quality decreased'
• One beep and a long pause is 'no air link'
• Any other signal does not relate to antenna alignment
Note
The ODU buzzer only works on the radio connected to the ANT 1 connector
marked . You will therefore need to use ANT 1 to align both antennas
in turn. Upon completion of the alignment procedure, you may connect the
two antennas to ANT 1 and ANT 2 connectors.

Figure 4-7: Opening RADWIN Manager window prior to installation
A detailed field by field description of the contents of the RADWIN Manager
main window may be found in chapter 5.
The procedure required to make the link functional has three phases:
1. Link Installation - which we will detail below.
Installation actually gets the link operational by setting the link parame-
ters. It uses a fixed channel at the lowest possible modulation, BPSK at
6.5Mbps and will work under the harsh interference condition.
2. Link Configuration - described in chapter 5.
Configuration provides much the same functionality as Installation, but
for a running link. A fallback to Installation mode is provided for situa-
tions which cannot be handled without resetting the link, such as
antenna realignment and IDU or ODU replacement.
The Link Installation and Configuration phases are both carried out with
Wizards, which “walk you through” the processes. The Wizards are visu-
ally quite similar and will be described in detail below.
Note
During the installation procedure, the definition of all parameters is
automatically applied to both sides of the link.
Default Settings Chapter 4
RADWIN 1000/2000 User Manual Version 2.12 4-9
3. Site Configuration - described in chapter 6.
Site specific configuration for each side of the link is available at any time
- under a running link or under the restricted Installation mode.
Site Configuration consists of a set of panels, which may be invoked indi-
vidually in any order, as needed.
Default Settings
The default settings of the RADWIN 1000/2000 configuration parameters
are listed in table 4-3 below:
Front Panel LEDs on the IDU-C
The front panel LEDs on the IDU provide basic information about link sta-
tus.
Note
An installed and configured link can be returned to installation mode for re-
installation and configuration from last settings or from factory settings.
• Reversion to installation mode requires a complete break in the link
service
• Configuration mode may vary the service throughput and quality, but
without a service break

General Chapter 4
RADWIN 1000/2000 User Manual Version 2.12 4-20
.
Figure 4-15: Transmission Power and Antenna Parameters
The choice of Tx power, antenna gain and cable loss determines the EIRP
and is affected by such considerations as radio limitations and regulatory
restrictions.
Before proceeding to antenna installation details, the following background
information should be considered:
General
Each RADWIN 1000/2000 ODU is made of two radio transceivers (radios).
The radios make use of algorithms that utilize both polarization and space
diversity resulting in enhanced capacity, range and link availability. The
number of antennas (i.e. radios) used is determined by user configuration
and by automatic system decisions, explained below.
Dual Antennas at Both Sites
Using dual antennas at both sites (single bipolar antenna or two monopolar
antennas) enables the use of MIMO technology. With MIMO the system
doubles the link capacity. At the same time, it keeps the same rate and
modulation per radio as was used with single antenna, thus increasing
capacity, range and availability.
Single Antennas at Both Sites Chapter 4
RADWIN 1000/2000 User Manual Version 2.12 4-21
For example with a dual antenna RADWIN 1000/2000 can transmit at mod-
ulation of 64QAM and FEC of 0.83 and get an air rate of 130 Mbps, com-
pared to 65 Mbps with single antenna.
To work in this mode, each antenna port must be connected to an antenna,
the RSS level in both receivers should be balanced and a minimal separation
between the antennas must be maintained. (For example, by using dual
polarization antennas a cross polarization separation is attained).
Upon selecting Antenna Type as Dual, RADWIN 1000/2000 automatically
doubles the air rates.
RADWIN Manager indicates a case of unbalanced RSS between the two
antennas.
Single Antennas at Both Sites
By selecting a single antenna at both sites the ODUs operate with a single
radio that is connected to the ANT 1 connector. The second radio is auto-
matically shut down.
Single and Dual Antennas
In this mode one of the sites uses the ODU with a single antenna while the
other site uses the ODU with a dual antenna.
The advantages in this mode in comparison to using a single antenna in
both sites are doubled total Tx power and additional polarization and/or
space diversity.
RADWIN 1000/2000 automatically switches to this mode if one of the ODUs
is connected to a dual antenna or if the RSS at one of the ODU receivers is
below minimal level.
The air rates used in this mode are same as when using single antennas in
both sites.
Considerations for Changing Antenna Parameters Chapter 4
RADWIN 1000/2000 User Manual Version 2.12 4-22
The rates used by RADWIN 1000/2000 are shown in Table 4-5 below:
Considerations for Changing Antenna Parameters
Let:
maxAllowedTx Power denote the maximum Tx Power practically avail-
able from an ODU. It appears as Tx Power per Radio in
figure 4-16 below.
maxRegEIRP denote the maximum EIRP available by regulation. It will be
determined by three factors:
• per band/regulation
• per channel bandwidth
•antenna gain
It appears in figure 4-16 as Max EIRP.
maxRegTxPower denote the maximum regulatory Tx Power for the
equipment, also having regard the above three points

maxODUTxPower denote the maximum Tx Power of the ODU, itself
depending on the air rate used.
Then, the following relationship must be satisfied:
... (*)
These parameters are controlled as follows:
¾To set Tx power and configure antennas:
1. Click the Configure buttons in turn to configure the antennas on both
sides of the link. Each one offers a dialog like this:
Figure 4-16: Antenna configuration dialog with opened type selection
2. Choose the antenna type and required transmission (Tx) power for the
first site and click OK. Repeat the process for the second site.
The Tx power (per radio) indicates the power of each radio inside the
ODU and is used for Link Budget Calculations. The Tx power (System)
shows the total transmission power of the ODU and is used to calculate
the EIRP according to regulations.
Note
To see the relationship between Tx Power (radio) and TX Power (system),
