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 outcome 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.
Chapter 2
Site Preparation
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 wireless system is able to operate efficiently and provide connectivity without
signal degradation.
RADWIN 1000/2000 offers a wide operating frequency range. A free frequency channel must be determined within the operating range, for optimum performance.
Recommended Equipment
Stage 1: Preliminary Survey
• Topological map of the area
RADWIN 1000/2000 User Manual Version 2.12 2-1
Stage 1: Preliminary Survey Chapter 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 facility 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.
¾ To 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 specified 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 physical 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, relative to north.
6. If there are obstructions between the two sites, calculate the Fresnel
Zone (see appendix D for details).
RADWIN 1000/2000 User Manual Version 2.12 2-2
Stage 2: Physical Survey Chapter 2
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.
It is advisable to go on a clear day, so you can more easily see any
obstructions between the two sites.
Note
¾ To perform a physical survey:
Note
1. From the compass readings taken in the preliminary survey, find the azimuth (horizontal position) that the ODU should face towards the second
ODU.
2. Using binoculars, locate any obstructions such as tall trees, high buildings, 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, considering 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.
The IDU - ODU cable length limit is 100m, in accordance with IEEE 10/
100BaseT standards.
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.

Additional Outdoor Site Requirements Chapter 2
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.
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

Safety Practices
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.
Chapter 3
Preventing overexposure to RF energy
To protect against overexposure to RF energy, install the ODUs so as to provide 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 equipment 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
RADWIN 1000/2000 User Manual Version 2.12 3-1
Protection against Lightning Chapter 3
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 telecommunication 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.

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.
¾ To align ODUs with integrated antennas or external bipolar antennas:
1. For external bipolar antennas: Using a coax cable with N-Type connectors, 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 connectors, 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 beeping 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.
When aligning the antennas, do not stand in front of a live antenna.

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.
During the installation procedure, the definition of all parameters is
automatically applied to both sides of the link.
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 situations 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 visually quite similar and will be described in detail below.
RADWIN 1000/2000 User Manual Version 2.12 4-8
Default Settings Chapter 4
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.
An installed and configured link can be returned to installation mode for reinstallation and configuration from last settings or from factory settings.
Note
• 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
.
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.
RADWIN 1000/2000 User Manual Version 2.12 4-20
Single Antennas at Both Sites Chapter 4
For example with a dual antenna RADWIN 1000/2000 can transmit at modulation of 64QAM and FEC of 0.83 and get an air rate of 130 Mbps, compared 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 automatically 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
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

These parameters are controlled as follows:
¾ To 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:

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.
To see the relationship between Tx Power (radio) and TX Power (system),

• The Max EIRP level will be automatically set according to the selected
band and regulation.
Note
• The EIRP level is the sum of the System Tx power and the Antenna
Gain minus the Cable Loss.
If inequality (*) above is violated, then the following warning window is
displayed:
