Regulatory Compliance
General Note
This system has achieved Type Approval in various countries around the world. This means
that the system has been tested against various local technical regulations and found to
comply. The frequency bands in which the system operates may be “unlicensed” and in these
bands, the system can be used provided it does not cause interference.
FCC - Compliance
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications to this equipment not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.

Caution
It is the responsibility of the installer to ensure that when using the outdoor
antenna kits in the United States (or where FCC rules apply), only those
antennas certified with the product are used. The use of any antenna other
than those certified with the product is expressly forbidden by FCC rules 47
CFR part 15.204.
It is the responsibility of the installer to ensure that when configuring the
radio in the United States (or where FCC rules apply), the Tx power is set
according to the values for which the product is certified. The use of Tx
power values other than those, for which the product is certified, is
expressly forbidden by FCC rules 47 CFR part 15.204.
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 void the product
warranty and may expose the end user or the service provider to legal and
financial liabilities. Resellers or distributors of this equipment are not liable
for injury, damage or violation of regulations associated with the installation
of outdoor units or antennas. The installer should configure the output
power level of antennas according to country regulations and antenna type.

Mobility Applications
RADWIN 2000 radios have been successfully deployed in a variety of Mobility Applications:
Border Control
RADWIN 2000 may be used in both towers and patrol vehicles to provide live video surveillance. Handoff from tower to tower as the patrol vehicles moves along the patrol road is
seamless. The towers may be sited several kilometers apart (depending on topography) and
are themselves synchronized using RADWIN GSU.
Installation Security
Securing an installation like a factory or an airport is broadly similar to Border Control, however the distance are smaller and the towers may be connected to a control room using
cables.
Railway solutions
This is a relatively new application and includes for example,

Key Features of RADWIN 2000
Chapter 1
Built on advanced MIMO and OFDM technologies, the RADWIN 2000 system provides
a high-capacity link at channel bandwidths of 5, 10 and 20MHz. These channel
bandwidths supports high robustness of the air interface under interference and harsh
conditions.
»
Multi-band Products
Every RADWIN 2000 Multi-band radio supports multiple frequency bands. For example
the RW-2050-0250 connectorized radio supports the bands: 5.9 GHz, 5.8 GHz, 5.4
GHz, 5.3 GHz, 4.9 GHz, 2.4 GHz and 3.4-3.7 GHz. The RADWIN 2000 Multi-band products support the regulations of FCC, IC Canada, ETSI and WPC India. DFS is supported where required by regulation.
»
Advanced Air Interface
The RADWIN 2000 system provides an advanced air-interface based on MIMO,
antenna diversity and OFDM technologies, resulting in an exceptionally robust air
interface and high frequency band granularity.
Using the following technologies, the RADWIN 2000 air interface is designed to ensure
nonstop, high quality transmission, even under interference and harsh conditions:
»
•
Automatic Adaptive Rate (AAR) is a mechanism that dynamically adapts the air
interface rate by changing both the signal modulation and coding.
•
Automatic Channel Selection (ACS) chooses the best channel by monitoring the
available radio channels and dynamically selecting a channel which is best suited
for transmission at any given time.
•
Automatic Repeat Request (ARQ) is a mechanism for error control during data
transmission. When the receiver detects an error in the received information, it
automatically requests the transmitter to resend the information. This process is
repeated until the transmission is error free or the error continues beyond a predetermined number of maximum transmissions. RADWIN 2000's ARQ mechanism
is optimized for time-critical traffic.
•
Forward Error Correction (FEC) with very low overhead and algorithms specifically designed for the varying conditions of license-exempt frequency bands,
ensuring fast, robust and error-free communications.
High transmission (Tx) power
The RADWIN 2000 system supports high Tx power, compliant with radio regulations.
High Tx power increases the system's availability and range, and enables the high
performance with smaller antennas, thus reducing the total cost of the solution (lower
CAPEX), installation and tower rent costs (lower OPEX).
The 5 GHz bands support a maximum Tx power of 25dBm whereas the 2.4 GHz band
supports a maximum Tx power of 26dBm.
»
Superior range performance
The RADWIN 2000 system supports high capacity at superior ranges. The Link Budget
Calculator (Chapter 21) is used to determine the capacity and range according to the
choice of product, antenna, type of service and environmental conditions.
»
HSS Interoperability between RADWIN 2000 and WinLink 1000
Site Synchronization is supported with any mix of RADWIN 2000 and WinLink 1000
links. RADWIN 2000 can be used to backhaul WinLink 1000 collocated links without
mutual interference

Chapter 1
Monitored Hot Standby (1+1):
The RADWIN Monitored Hot Standby (MHS) protects up to sixteen E1/T1 services with
RADWIN 2000 and up to four E1/T1 services with WinLink 1000. It is designed to
provide high reliability high-capacity Point-to-Point Links. The RADWIN MHS is •
Designed to provide redundancy and high reliability for carrier class operators
•
Optimized for high capacity links operating in license-free bands
•
A comprehensive solution providing protection against both equipment failure
and loss of air interface, by simple connectivity between a primary link and a secondary link
•
Able to use a different band for maximum protection to the air interface
The main features of the RADWIN MHS are –
•
Cut-over from the primary to the secondary link completely automatic
•
Cut-over time no more than 50 ms
•
Automatic restore to primary link as soon as it becomes available
•
WinLink 1000 can backup a RADWIN 2000 link
A major benefit of RADWIN MHS is that is can underpin an affordable Service Level
Agreement structure by protecting part of the RADWIN 2000 trunks with WinLink
1000.
MHS supports TDM services; Ethernet services are carried by both links independently.
»

Components of a RADWIN 2000 Link
Chapter 1
CCM/AES uses a symmetric 128-bit encryption key (EK), and a nonce, and provides both message encryption and authenticating signature. The nonce mechanism enables the receiver to remember already received genuine messages and
reject all replayed messages.

•
Initial encryption and authentication is based on a user-defined master key (Link
Password). While standard Wireless LAN encrypts only the Ethernet Payload, the
AES encrypts both the source and destination MAC addresses.
•
In addition to normal log on access, Read or Write Community access is available
at log on
•
Link Lock is a part of the RADWIN 2000 security concept. It is designed to discourage physical theft of units and “piggybacking” using an otherwise identical
ODU to steal bandwidth or information. It locks a pair of synchronized ODUs for
mutually exclusive communication.
SFP support in the IDU-C
Standard SFP modules are used, enabling any type of Ethernet physical connectivity
including various fiber connections. E3/T3 or E1/T1 over Ethernet SFPs can be used as

A Little Terminology
Chapter 1
A Little Terminology
In the field, a link typically has a local or headquarters site as for example in Figure 1-1
above. Here the service provider is the local or headquarters site. The service recipient is the
remote site.
Where the link is completely internal to a corporation, the choice of the local and remote is
just a matter of convenience.
A link then, consists of two sites.
In Broadband Wireless terminology, the local and remote sites are sometimes referred to as
“near” and “far”, “HQ” and “remote” and so on.
The site which is closer to the network core (often the local site) will be referred to as site A,
and the opposite side of the link, usually closer to the end user, as site B.
This choice is application-neutral and will be used throughout the manual both to describe the
sites and their names as in the examples.
The link is configured and managed using a PC, the managing computer connected to site
A. (The precise requirements for the managing computer are set out on page 4-1).
We will occasionally need to distinguish between the site to which the managing computer is
connected, and the second site, when they are not necessarily A or B. The former will be
called the managing site and the latter, the over-the-air site. Which is which, is always
determined by the location of the managing computer.
RADWIN 2000 supports three connection methods for the managing computer:
•
Local - a direct peer to peer connection between the Ethernet ports on the managing
computer and the IDU or PoE device. Local connection is always read-write.
•
Network - the managing computer and the site A IDU or PoE device belong to a LAN
and communicate through a router or switch
•
Over-the-air - the managing computer connects to site B via the air interface
•
The managing computer may be connected to the link through an IDU or a PoE
device. In what follows, where ever we refer to an IDU it includes PoE devices unless
stated otherwise. Typically, if we need to refer to an IDU as such, we will use a model
name such as IDU-C.
The terms uplink and downlink, originate from the field of Satellite communications. In a
backhaul or ISP context, uplink is from the user to the network and downlink is from the
network to the user.

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 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 indoor and outdoor equipment are determined onsite.
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
radio installation (on-site).
The Site Survey
Introduction
RADWIN 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 2000 offers a wide operating frequency range. A free frequency channel must be
determined within the operating range, for optimum performance.

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.
 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 equipment.
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
Chapter 21 for details).
7. If the site chosen does not meet requirements, consider alternative sites.
8. Use the Link Budget Calculator (on the CD supplied with the equipment or using the
RADWIN Manager) to determine the expected performance.

Stage 2: Physical Survey
Chapter 2
Stage 2: Physical Survey
The physical site survey reviews the environment of the proposed installation location, to
ensure that the link sites are suitable for the wireless network. The results of the physical site
survey should be recorded.
Note
It is advisable to go on a clear day, so you can more easily see any
obstructions between the two sites.
 To perform a physical survey:
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 Chapter 21).
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.
Note
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 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.
9. Review the results of the physical site survey. Decide if the site is suitable for the
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).

•
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 installation site, to determine
whether there are available channels within the radio 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 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 marker in the Quality bar on the Channel
Setting window (see Figure 5-6) moving into the green area.
RF Planning for Dense Installations and Collocated Sites
Interference may arise from
•
Self interference from collocated RADWIN radios
•
Other collocated radio devices installed on the same site.
To avoid or minimize interference, follow these recommendations:
•
For collocated RADWIN units, use an HSS unit to synchronize between them. Select a
different operating channels for each collocated RADWIN unit.
•
If one or more collocated units are not RADWIN units, ensure that there is a physical
separation of at least three meters between a RADWIN unit and any other collocated
radio on the site.
•
Use the largest possible frequency gap between these units.
•
Choose the best frequency channel (as clear as possible form interference). You may
change band with “Combo” WinLink 1000 products and all RADWIN 2000 products).
•
To select a frequency channel, move the link to Installation Mode (using Site configuration) and start the Installation wizard. In the Channel Settings window, use
the quality bar at the bottom to help you choose a better channel (clearer of interference).
•
If you are using WinLink 1000 radios, install the collocated links with different antenna
polarizations.
•
If you are using the RADWIN 2000 radios, use the Spectrum View tool to find the
best working channel (Tools | Spectrum View).

Warning
Note
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.
The material in this chapter is generic to all RADWIN radio link products
unless stated otherwise.
Safety Practices
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 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

Chapter 3
outdoor unit, mast, lead-in wire and discharge unit. It also lays down the size of
grounding conductors and connection requirements for grounding electrodes.
The RADWIN 2000 ODU must be grounded to a Protective Earth as described in
Chapter 18 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 Chapter 18.
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 Chapter 18 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 2000 always use the AC power adapter
supplied by RADWIN.

Outdoor installation
Preparing the ODU before Deployment
Each ODU must be pre-loaded with an IP address. This may be done prior to deployment in
the field, or on-site using a Laptop computer. The process is quite straight-forward and
described in Chapter 19.
Mounting the ODU
The ODU can be mounted on a pole or a wall. In both installations, the supplied mounting kit
is used to secure the ODU.
A mast-sited ODU typically uses a pole attached to the mast.
Note
A RADWIN 2000 link operates in pairs of two ODUs with the same configuration. Both ODUs
must be installed, and the antennas aligned for maximum throughput.
Prior to connecting cables to the ODU, the protective earth terminal (screw)
of the ODU must be connected to an external protective ground conductor
or to a grounded pole.
Warning
•
•
Only a qualified person using the proper safety equipment should
climb the antenna mast
Only qualified professional personnel should install or dismantle
ODUs and masts
 To mount the ODU on a pole or a wall:
1. Ensure that the ODU is properly grounded.
2. Mount the ODU onto the pole or wall. Ensure that the unit is oriented so that the
cable connectors are at the bottom. (If they are on top, water may penetrate
into the unit causing damage.) It is possible to mount an ODU horizontally. See
Chapter 17 for details.
3. Refer also to Chapter 17 for detailed ODU mounting kit contents and schematics.
•
Note
•
Do not tighten the ODU to its mounting brackets until the alignment
process of the antenna is complete.
Ensure that there are no direct obstructions in front of the ODU or
interference from man-made obstacles.
Mounting external antennas
If you are using ODU with an integrated antenna, skip to Mounting the Lightning Protection Devices below.

then mount the antenna onto the pole. Refer to Chapter 17 for detailed antenna
mounting instructions.
2. Follow the mounting instructions supplied with the antenna.
Mounting the Lightning Protection Devices
The use of lightning protection is dependent on regulatory and end user requirements. The
RADWIN 2000 ODU is 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.
Refer to Chapter 18 for detailed installation instructions of lightning protection devices.
Outdoor Connections
 To complete the outdoor connections:
1. Connect the ground cable to the ODU chassis as marked on the ODU.
2. Connect the antenna cable(s) to the ODU.
3. Connect the lightning protection device to the ODU (see Chapter 18).
4. Attach the ODU-IDU cable to the ODU RJ-45 connector (see Appendix B for the

Connecting the ODU to the IDU
Chapter 3
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 (328ft) 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 3-10 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.
 To 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 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
 To connect user equipment to an IDU:
1. Connect user switch/router or any other compatible device to the IDU panel RJ-45
ports designated LAN. (For an IDU-C, see item C in Figure 3-10 above.)
2. Connect user E1/T1 traffic to the IDU panel RJ-45 ports designated TRUNKS. (For an
IDU-C, see labeled item L in Figure 3-10 above.)
3. IDU-C only: To use the SFP Port (labeled item D in Figure 3-10 above), insert an
SFP plug-in module into the port and connect the user switch/router or any other
compatible device to the SFP plug-in module.
Refer to Appendix B for connector pinouts.
Do not connect two LAN ports to the same network, or flooding may occur.
Note
 To connect user equipment to a 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 for connector pinouts.

Connecting and Aligning ODUs / Antennas
Chapter 3
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 2000 system should be performed
by two teams simultaneously, at site A and at site B.
 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.
Warning
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, listening to the
tone until the best signal is reached. See the following figure for audible signal variations.

8. Secure the site A antenna to the pole/wall.
9. Repeat steps 4 to 8 for site B.
 To align two external monopolar antennas:
The ODU buzzer only works on the radio connected to the ANT 1 connector
marked
Note
. 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.
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 follow 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.

Getting Started with the RADWIN Manager
If your links are within easy reach, you can configure them using the procedure described
below. If however, your links are to be geographically scattered, it may be convenient to preload each ODU with its network address prior to physical installation. The procedure is quite
straight forward, and set out in Chapter 19.
Note
Each ODU requires a static IP address, since part of the link definition is the
IP address pair of both ODUs. Network Managers should ensure that these
addresses are outside of the automatic allocation ranges used by their
network DHCP server.
 To start the RADWIN Manager:
1. Connect the managing computer to one of the two LAN ports as shown in Figure 41 below:

addresses:
Note
Our managing computer has its NIC set to IP address 192.168.1.100. The
log-on ODU is set to IP address 192.168.1.101 and the over-the-air ODU is
set to 192.168.1.102. The Subnet Mask for both sites is 255.255.255.0 and
the Default Gateway is left unset. We will maintain this arrangement
throughout the remainder of this manual.

Note
A detailed field by field description of the contents of the RADWIN Manager main window
may be found in Chapter 6.
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 parameters. It uses a fixed
channel at the lowest possible modulation, BPSK at 6.5Mbps and will work under the harsh
interference condition.
Note
During the installation procedure, the definition of all parameters is
automatically applied to both sides of the link.
•
Caution
•
The ODUs as supplied by RADWIN are set up with a factory default
band. If for some reason the default band needs to be changed, it
should be done before link Installation. The procedure is set out in
Chapter 20.
Use of an incorrect band may be in violation of local regulations.
2. Link Configuration - described in Chapter 7.
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.
3. Site Configuration - described in Chapter 8.
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 individually 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

Installing the Link
Overview
The installation is carried out using the Installation wizard. Its operation is detailed in the following pages in a tutorial style.
For the purpose of explanation, we will set up a laboratory link with the following characteristics:
•
Channel selection: Automatic
•
Antennas: Dual at both sites
•
Services: Ethernet + 7xE1 on ports 1, 2, 3, 8, 10, 11, 14. It is unlikely that you would
use a non-contiguous set of ports - but this shows that if required, it can be done.
The Installation wizard has steps as shown in Table 5-1 below.

Step 4, Tx Power and Antenna Settings
The Tx Power and Antenna Parameters dialog appears.
Figure 5-9: Transmission Power and Antenna Parameters
The choice of Tx Power, antenna gain and cable loss (between the radio and the antenna)
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:
About Single and Dual Antennas
Each RADWIN 2000 ODU is made of two radio transceivers (radios). The radios make use of
algorithms that utilize both MIMO and 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
When using dual antennas at both sites (single bipolar antenna or two mo-unipolar antennas)
you can choose between MIMO Mode and Diversity Mode.
RADWIN 2000 User Manual
Release 2.5.40
5-9
Installation
Chapter 5
MIMO Mode
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.
For example with a dual antenna RADWIN 2000 can transmit at modulation of 64QAM and
FEC of 5/6 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 2000 automatically selects MIMO mode and
doubles the air rates.
RADWIN Manager indicates a case of unbalanced RSS between the two antennas.
Diversity Mode
Diversity Mode uses two antennas to improve the quality and reliability of the link. Often,
there is not a clear line-of-sight (LOS) between transmitter and receiver. Instead the signal is
reflected along multiple paths before if-ally being received.
Each such “bounce” can introduce phase shifts, time delays, attenuations, and even distortions that can destructively interfere with one another at the aperture of the receiving
antenna. Antenna diversity is especially effective at mitigating these multi-path situations.
This is because multiple antennas afford a receiver several recordings of the same signal.
Each antenna will be exposed to a different interference envy-remnant. Thus, if one antenna
is undergoing a deep fade, it is likely that another has a sufficient signal. Collectively such a
system can provide a or-bust link.
Antenna diversity requires antenna separation which is possible by using a dual-polarization
antenna or by two spatially separated antennas.
Use Diversity instead of MIMO in the following situations:
•
When the system cannot operate in MIMO Mode
•
When one of the receivers has high interference compared to the second receiver (i.e.
the system is “unbalanced”)
•
When you achieve higher capacity in Diversity Mode than in MIMO Mode
•
When high robustness is of importance and the capacity of Diversity Mode is sufficient
(up to 25 Mbps full duplex)
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 at One Site, Dual Antennas at the Other
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 (depending on the
polarization of installed antennas).

Considerations for Changing Antenna Parameters
Let:
max Available Tx Power denote the maximum Tx Power practically available from an
ODU. It appears as Tx Power per Radio in Figure 5-10
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 5-10 as Max EIRP.
maxRegTxPower denote the maximum regulatory Tx Power for the equipment, also
having regard the above three points.
Then, the following relationship must be satisfied:
maxAvailableTxPower  min(maxRegEIRP
– AntennaGain + CableLoss maxRegTxPower)
... (*)
These parameters are controlled as follows:
 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. You will receive the following warning:
Figure 5-11: Antenna type change warning
3. Repeat the process for the second site.
4. At the same time you can set the Antenna Gain and Cable Loss.
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),
note that dBm = 10  log 10milliWatt so that if you double the power in
Note
milliWatts (for two radios) then dBm will increase by 10  log 102  3 .
If you choose to set the Antenna Gain and Cable Loss, you will receive the following
warning message:

•
Note
•
The Max EIRP level will be automatically set according to the selected
band and regulation.
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:
Figure 5-13: Tx Power Limits
The precise relationship between the items in inequality (*) and the window of
Figure 5-10 is as follows:
•
Required Tx Power (per radio) will be adjusted down to the lesser of the value
entered and maxAvailableTxPower
•
Tx Power (system) is maxAvailableTxPower + 3 (for 2 radios)
•
Max EIRP is maxRegEIRP.
•
EIRP is maxAvailableTx Power + Antenna Gain - Cable Loss
The table in Figure 5-13 only shows rates where the maximum Tx Power is the limitation, rather than regulations. When you close the window of Figure 5-13, the
change you requested will not be honored, and you will need to try again.

Since our demonstration link is entirely indoors, we have reduced Tx Power
to 5 dBm to obtain a realistic RSS. Although this is much too low for field
use, the method is general.

Configuring the Link
Overview
This chapter describes the link configuration procedure, which is performed after the installation of both sides of the RADWIN 2000 link, as set out in Chapter 5.
Link configuration uses a Link Configuration wizard to redefine the configuration parameters
and fine-tune an operational link. Both sides of the link are configured simultaneously.
Link configuration allows you to configure link parameters, which do not lead to sync loss or
require a reset. Some may change service performance, in respect of which, warnings are displayed.
For ease of use, the Link Configuration wizard follows the same pattern as Link Installation.
You should therefore be familiar with the content of Chapter 5.
The following parameters are configured using the Link Configuration Wizard:
•
System parameters
•
Channel settings
•
Transmission power and antenna settings
•
Service parameters
The Configuration Wizard has seven steps as shown in Table 7-1 below.

The Channel Bandwidth may also be changed. The available choices are 10, 20 and 40MHz
depending on regulation (see Appendix A).
When you have completed making your choice, click Next to continue.
Step 4, Tx Power and Antenna Settings
The Tx Power and Antenna Settings window is similar to that for Installation:
Figure 7-8: Transmission Power and Antenna Parameters
As in Installation mode, you need to consider three items:
•
Number of antennas at each Link site (1 or 2)
•
Tx Power setting for each one
•
MIMO or Diversity mode
Changing Number of Antennas and Tx Power
TX Power, Antenna Gain and Cable Loss
If you chose to configure either antenna, you are presented with the following window:

(Recall that we are using an unrealistically low Tx power here because our link in a laboratory.)
So far, the procedure duplicates the corresponding Installation process. If you choose a different antenna type and click OK, you will receive the following cautionary message:
In this context, entering Installation mode causes a service break until it is
restored by running the Installation wizard.
Caution
If you are uncertain, do not do this without expert technical assistance.
You may also change the Required Tx Power, Antenna Gain and Cable Loss. The procedure is
the same as that set out in the Installation procedure on page 5-13.
Switching Between Single and Dual Antennas
Single/Dual Antenna mode selection works precisely the same way as shown on page 5-20.
If you use this option you will receive a warning similar to this:

Configuring VLAN Settings
Caution
VLAN IDs are used by RADWIN products in three separate contexts:
Management VLAN, Traffic VLAN and Ethernet Ring. It is recommended that
you use different VLAN IDs for each context.
VLAN Management enables separation of user traffic from management traffic whenever such
separation is required. It is recommended that both sides of the link be configured with different VLAN IDs for management traffic. (This reduces your chances of accidentally locking
yourself out of the link.)
 To enable VLAN management:
1. Click Configuration from the main menu.

2. Choose a site to configure. If you are configuring both sites, choose site B first to
avoid locking yourself out.
3. Choose Management.
4. Open the VLAN tab.
5. Check the Enabled box.
6. Enter a VLAN ID. Its value should be between 1 and 4094.
After entering the VLAN ID, only packets with the specified VLAN ID are processed
for management purposes by the ODU. This includes all the protocols supported by
the ODU (ICMP, SNMP, TELNET and NTP). The VLAN priority is used for the traffic
sent from the ODU to the managing computer. Using VLAN for management traffic
affects all types of management connections (local, network and over the air).
7. Enter a Priority number between 0 and 7.
8. Change the VLAN ID and Priority of the managing computer NIC to be the same as
those of steps 6 and 7 respectively.
Caution
Changing this parameter causes the RADWIN Manager to immediately
disconnect. To avoid inconvenience, you should verify the change by
setting the VLAN only to one ODU, and only after verifying proper
management operation, change the other ODU VLAN setting.
9. Click Apply or OK.

RADWIN Manager Community Strings
The ODU communicates with the RADWIN Manager using SNMPv1 protocol. The protocol
defines three types of communities:
•
Read-Only for retrieving information from the ODU
•
Read-Write to configure and control the ODU
•
Trap used by the ODU to issue traps.
The Community string must be entered at log on. The user must know the password and the
correct Community string to gain access to the system. A user may have read-only privileges.
It is not possible to manage the ODU if the read-write or the read Community values are forgotten. A new Community value may be obtained from RADWIN Customer Support for the
purpose of setting new Community. You must also have available the serial number or the
MAC address of the ODU.
The read-write Community strings and read-only Community strings have a minimum of five
alphanumeric characters. (bru1 and bru4097 are not permitted). Changing the trap Community is optional and is done by clicking the check box.

Link Lock Security Feature
Link Lock is a part of RADWIN’s security concept intended to meet a form of abuse
encountered in the field. It is designed to prevent the situation where a remote ODU
can be stolen and used as a “pirate” link to steal services or information. The Link
Lock feature actually locks the local ODU to be synchronized ONLY to specific remote
ODU. It is a site oriented feature.
The lock can only be set from a live link. It is based on MAC authentication and is site
oriented and activated on a per ODU basis. For example, if you lock the Site B ODU to
the Site A ODU, you must still lock the Site A ODU to the Site B ODU to ensure
complete two way locking.
Link Lock can only be removed when the link is unsynchronized. In such a case, an
alarm is raised by the RADWIN Manager.
 To enable Link Lock:
1. Click Site A on the main tool bar.
2. Choose the Security tab. The following window is displayed:

Note
To revert the Link Lock status to unlocked, power down each ODU
in turn. Use the above procedure to uncheck the Link Lock status
box for the live ODU.
A simple ODU reset at either end will restore the link to its previous
locked or unlocked state.
Setting the Date and Time
The ODU maintains a date and time. The date and time should be synchronized with any Network Time Protocol (NTP) version 3 compatible server.
During power-up the ODU attempts to configure the initial date and time using an NTP Server.
If the server IP address is not configured or is not reachable, a default time is set.
When configuring the NTP Server IP address, you should also configure the offset from the
Universal Coordinated Time (UTC). If there is no server available, you can either set the date
and time, or you can set it to use the date and time from the managing computer. Note that
manual setting is not recommended since it will be overridden by a reset, power up, or synchronization with an NTP Server.
The NTP uses UDP port 123. If a firewall is configured between the ODU
and the NTP Server this port must be opened.
Note
It can take up to 8 minutes for the NTP to synchronize the ODU date and
time.

ODU Mode
RADWIN 2000 C-Series ODU products work in Hub mode only. The bridge
capability is built in to the IDU-C (it is not configurable). If an IDU-C is
connected to an RADWIN 2000 C ODU, then the IDU-C performs the
bridging.
Note
This parameter controls the ODU mode with two optional values:
•
Hub Mode - in Hub mode the ODU transparently forwards all packets over the wireless
link.
•
Bridge Mode - In Bridge mode the ODU performs both learning and aging, forwarding
only relevant packets over the wireless link. The aging time of the ODU is fixed at 300
seconds.
Changing these modes requires system reset.
Note
IDU Aging time
This parameter controls the IDU aging time.
The aging time parameter controls the time after which each MAC address is dropped from
the MAC address learning table.
The default value is 300 seconds.
•
•
Note
Any change to these parameters is effective immediately.
Each side of the link can be configured separately, with different
aging times.

Configuring Ethernet Ports Mode
The ODU Ethernet port is configured to auto-detect by default and may not be changed.
The ODU Ethernet port mode is configurable for line speed (10/100BaseT) and duplex mode
(half or full duplex).
An Auto Detect feature is provided, whereby the line speed and duplex mode are detected
automatically using auto-negotiation. Use manual configuration when attached external
equipment does not support auto-negotiation. The default setting is Auto Detect.
Caution
You should not reconfigure the port that is used for the managing computer
connection, since a wrong configuration can cause a management
disconnection or Ethernet services interruption.
 To configure the Ethernet Mode:
1. From the Configuration menu, choose the site to configure.
The Site Configuration dialog box opens.
2. Click Advanced | Ethernet.
3. In the Ethernet Ports Configuration pane, use the drop-down menu to choose the
configuration.
4. Click Apply to save the changes.
It is possible to close the Ethernet service by disconnecting the Ethernet
port.
If you close the port, you may subsequently be unable to access the
device. If this should occur, a workaround is as follows:
Note
•
•
•
Connect the system from the remote site
Connect via other Ethernet port (of the IDU)
Power down the equipment and connect immediately after power
up (the fastest way is to enter install mode)

Setting the Maximum Information Rate (MIR)
Chapter 8
The details of setting up VLAN tagging require advanced network management skills beyond
the scope of this manual. Further information for the Network Manager is provided in Chapter 14.
Setting the Maximum Information Rate (MIR)
What is the MIR
The maximum Ethernet throughput of the link (MIR) can be limited. The default setting is
Best Effort (see Figure 8-15 above), where the highest information rate available for the link
conditions and settings is used.
What is it for
The MIR setting limits the throughput for Ethernet service. It does not affect the capacity of
TDM services.
If the Link Budget Calculator or air conditions limit the capacity to X Mbps, and suppose that
you use Y (< X) Mbps for TDM services, then you are left with X - Y=Z Mbps for Ethernet.
Suppose for example, that Z = 20 Mbps.
As a Service Provider, you can decide to sell a package based on 10Mbps and charge $P1 for
it, or 15 Mbps for $P2 > $P1.
The MIR setting allows you do this.
The default value is “best effort” which will give Z above.
The minimum value is 256 Mbps.
The maximum value will be the minimum between Z above and -

10 Mbps for RADWIN 2000 PDH

during the interval, then for that threshold, the recommended BBER value should be 0. Since
the system provides a lossless Ethernet service, there is throughput degradation in case of
interference. The degradation is proportional to the BBER.
Ethernet Thresholds - Capacity
This is used as a basis for checking adherence to a Service Level Agreement. It is the number
of seconds count that the link capacity falls bellow the threshold.
Ethernet Thresholds - Traffic
The number of seconds count that received traffic exceeded this threshold. It can be used to
measure traffic peaks.

A “Dying-Gasp” circuit identifies the power failure at a minimum interval of 20 milliseconds
before the ODU or IDU powers off. During that interval a message notifying the power failure
is sent to opposite site. External alarm output number 4 indicates power failure at the opposite site.

UM 2000-2540/02.11
Chapter 10
Hub Site Synchronization
What is Hub Site Synchronization?
When several units are collocated at a common hub site, interference may occur from one
unit to another. RADWIN ODU units support the collocation of more than two units at a central site. Like any other RF deployment, the wireless operation is highly dependent on factors
such as available frequencies, the physical spacing between radios, other interfering radios,
and whether WinLink 1000 or RADWIN 2000 units are installed.
HSS does not eliminate the need for careful RF planning to ensure the
design will work as planned. See Chapter 2 of the User Manual (both
WinLink 1000 and RADWIN 2000) for information on installation site survey.
Note
For WinLink 1000 units, Hub Site Synchronization support depends on the
product model.
The RADWIN Hub Site Synchronization (HSS) method uses a cable connected from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize
their transmission with each other. The pulse synchronization ensures that transmission
occurs at the same time for all collocated units. This also results in all of the hub site units
receiving data at the same time, eliminating the possibility of interference that could result if
some units transmit while other units at the same location receive.
Figure 10-1 illustrates interference caused by non-synchronized collocated units.
RADWIN 2000 User Manual
Release 2.5.40

Adding HSS removes interference as shown in the next two figures:
Figure 10-2: Collocated units using Hub Site Synchronization (1)
Figure 10-3: Collocated units using Hub Site Synchronization (2)
The units are connected to each other with HSS cables and HSS Distribution Units.
One of the radios in the site is defined as HSS Master and generates synchronization pulses.
The other collocated radios in the site - the HSS Clients, are connected to the HSS Master and
synchronize their transmission to the pulses. An HSS Client can be configured to work in one
of two modes:
RADWIN 2000 User Manual
Release 2.5.40
10-2
Hardware Installation
Chapter 10
•
HSS Client-Continue Transmission (HSC-CT): If the unit loses synchronization
with the HSS Master, the link remains active. However, without synchronization pulses,
it is possible that this unit will cause interference.
•
HSS Client-Disable Transmission (HSC-DT): If the unit loses synchronization with
the HSS Master, the link is dropped until the synchronization pulses resume. This setting prevents the unit from causing interference.
The remote ODUs that are not located at the hub site, are called Independent Units.
Note
WinLink 1000 radios used as independent units do not require HSS
hardware.
Hardware Installation
Connecting an HSS Unit
A single HSS unit supports up to ten collocated ODUs. In addition to each unit being connected to its IDU or PoE device, the collocated unit has an additional cable that is connected
to the HSS Unit. The HSS Unit is a compact, weatherproof (IP67) connector box that is
installed on the same mast as the ODUs. All collocated units connect to this box using CAT-5e
cable. Cables in prepared lengths are available for purchase.
The HSS unit is supplied with ten protective covers; any port not in use must be closed with a
protective cover.
Figure 10-4: HSS Interconnection Unit
•
Note
•
For a single HSS unit, ensure that the collocated units are connected
in sequence from SYNC 1. If an ODU is removed from the hub site,
then all remaining ODUs must be reconnected to maintain the connectivity.
You may cascade (daisy-chain) two or more HSS Units with an HSS
cable. The method is described in detail below.
 To connect an ODU to an HSS unit:
1. Unscrew the protective cover from the port marked SYNC 1.
2. Connect the RJ-45 connector from one end of the prepared CAT-5e cable to SYNC 1.
3. Connect the other end of the CAT-5e cable to the ODU connector labeled SYNC.

Using a Single HSS Unit
Chapter 10
4. Tighten the protective seal that is on the prepared cable over the RJ-45 connector.
5. Repeat for all ODUs that are to be collocated at the hub site. The next ODU to be
connected is inserted in SYNC 1, SYNC 2, followed by SYNC 3 and so on.
Using a Single HSS Unit
Figure 10-5: HSS Wiring schematic
The wiring, as shown in Figure 10-5 is self explanatory. The Sync signal path is less self evident. If we set ODU 1 (on SYNC 1) to HSS Master, then the Sync signal path is as shown in
Figure 10-6. The signal travels from ODU 1 to SYNC 1, from SYNC 1 to SYNC 2, from SYNC
2 to ODU 2 and back again. The back and forth paths repeat for the second to fourth ODU,
from left to right. The signal exits the HSS unit at SYNC 5 and terminates in ODU 5.
The choice of the ODU on SYNC 1 as HSS master is not mandatory, but is good practice. If for
example we were to use ODU 3 as HSS master, the Sync signal path would be ODU 3 to SYNC
3, then left and right to SYNC 2 and SYNC 4. It would then propagate to ODUs 2 and 4, terminating at both ODUs 1 and 5.

Using More than One HSS Unit
In a large collocation site, several HSS units may be cascaded (daisy-chained) subject to the
following conditions:
Condition 1: Cabling Sequence
1. Up to nine ODUs may be connected to the first HSS unit using HSS ports SYNC 1, SYNC 2,
SYNC 3,... up to SYNC 9 in order without leaving empty ports.
2. The next available SYNC port of the first HSS unit should be connected to SYNC 10
of the second HSS unit as shown in Figure 10-7. In the illustration, the next
available port on the first HSS unit is SYNC 6.
3. The second HSS unit may be filled out with up to nine more ODUs in reverse
order. That is, connect SYNC 9, SYNC 8, SYNC 7... as shown in Figure 10-7.
Figure 10-7: Cascading two HSS units
4. To add a a further HSS unit: Connect the next available SYNC port from the second
HSS unit in descending order (SYNC 5 in Figure 10-7) to SYNC 1 of the third
HSS unit.
5. ODUs are connected to the third HSS unit from SYNC 2 as shown in Figure 10-8,
in ascending order:

6. If further ODUs are required, observe the convention that additional even
numbered units are populated in descending order from SYNC 9 and odd
numbered HSS units are populated in ascending order from SYNC 2.
Note
If an ODU is disconnected from an HSS unit, then all remaining ODUs must
be moved up or down to maintain the connectivity.
Condition 2: Total HSS Cable Length
The total path of the HSS sync pulse must not exceed 300m. This applies no matter how
many HSS units are used. To illustrate the method for calculating the sync pulse path length
we show three examples. For our purpose, let:
Lmn denote the length of the ODU-HSS unit cable at SYNC n on HSS unit m
Hm be the length of the cable joining HSS unit m to HSS unit m+1

Radio Frame Pattern (RFP)
A Radio Frame Pattern (RFP) is the cycle duration of transmit and receive of the air-frame.
Without HSS
When selecting TDM or Ethernet services, the system automatically and transparently
chooses the optimal RFP. When TDM and Ethernet services are configured, the RFP is optimized for TDM.
RFP and HSS
When HSS is used, the RFP for the collocated radios must be selected manually.
Both WinLink 1000 and RADWIN 2000 use the Time Division Duplex (TDD) mechanism.
Under HSS, TDD enables synchronization of transmission for the collocated units as shown in

with the Table 10-2 and Table 10-3.
The tables describe the efficiency of the air interface according to the RFP type, radio products mix, services and channel bandwidth. The tables may also be viewed in the RADWIN

•
If you mix RADWIN 2000 and WinLink 1000 units in a collocated site, you must use
RFP B or E
•
Selection of the RFP influences the capacity, latency and TDM quality
•
RFP influences capacity and latency. Jitter buffer configuration can be used to set the
TDM quality (see the User Manual, Chapter 5, TDM Services selection)
•
Using the Link Budget Calculator, you can see the affect of the RFP on the Ethernet
throughput.
RFP: RADWIN 2000 Considerations
•
The performance of RADWIN 2000 radios that operate with RFPs B or E can be seen
in the Link Budget Calculator.
•
For RADWIN 2000 C series: If the HSS Master works in asymmetric Tx/Rx ratio, then
all other collocated RADWIN 2000 units must operate in the same Tx/Rx ratio. In this
case the ratio will be fixed and not automatic-adaptive.
•
Installation/Configuration considerations: If you are using RADWIN 2000 C master
and RADWIN 2000 clients, the Services and Rates dialog will look like this:
Figure 10-11: Services and Rates - RADWIN 2000 C master, RADWIN 2000 clients
•
The circled areas should not be used. Using those areas, you may loose the collocated
link with the longest distance between sites. If you do move the slider into a circled
area, you will receive a popup warning:

asymmetric allocation
By restricting one direction into the restricted area, the more distant sites may not
even be able to sustain the link much less send or receive data.
•
Asymmetric Allocation and Collocation: If the link is collocated, the use of Asymmetric
Allocation is limited.
The effective available range for Asymmetric Allocation (between the two circled tick
in Figure 10-11) is primarily determined by three factors:
•
The RFP in use (B or E)
•
Channel Bandwidth
•
Link distance
The first two parameters are entered during Link
Installation/Configuration.
•
Possible scenarios are shown in Table 10-4.Whenever Asymmetric Allocation is available, it is static for all traffic conditions.

RFP: WinLink 1000 Considerations
•
When WinLink 1000 radios are collocated with RADWIN 2000 radios using HSS, all
radios must use RFP B or E.
•
The performance of WinLink 1000 radios that operate with these RFPs can be seen in
the Link Budget Calculator.
•
The choice of the unit to be the HSS master is a matter of convenience. There is no
technical reason to prefer a WinLink 1000 over a RADWIN 2000 as HSS master or vice
versa. It is however, recommended that you use the RADWIN 2000 as master, since it
will enforce the correct RFP on the other collocated units.
The following list summarizes the effect of using RFP B or E on WinLink 1000 radios. These
effects should be taken into consideration when planning new installations:
•
Channel bandwidth 5 MHz is available under RFP E but is only supported for WinLink
Access products
•
For products supporting a maximum throughput of 18.1 Mbps, the maximum Ethernet
throughput is 14.5 Mbps at 20 MHz channel bandwidth and 9.3 Mbps at 10 MHz channel bandwidth
•
For products supporting maximum throughput of 22.5 Mbps, the maximum Ethernet
throughput is 21.4 Mbps at the 20 MHz channel and 9.3 Mbps at 10 MHz channel
bandwidth

Hub Sync Client - Continue Transmission (HSC-CT)
Continue Transmission is intended to work if there is no HSM pulse. If a
wrong HSM pulse is detected, a WinLink 1000 will resync, adapting to the
HSM RFP and continue whereas RADWIN 2000 may stop.

Using the RADWIN GSU
What is it for
The GPS-based synchronization unit (GSU) is designed to handle inter-site interferences
under large-scale deployment scenarios.
The GSU is an outdoor unit consisting of a standard WinLink 1000 enclosure, a GPS antenna
and a PoE device.
The GSU is connected to the HSS Unit using a standard HSS cable. It synchronizes the transmission timing of multiple Hub-Sites to the same clock source thus eliminating mutual interference.
GSU Functionality
The GSU receives a synchronization signal from the GPS once per second. It distributes a
RADWIN proprietary synchronization signal to all other ODU units using the RS422 protocol
and the standard HSS mechanism, where the GSU acts as an HSM unit.
When the GSU doesn’t receive a synchronization signal from the GPS for 30 seconds, it moves
automatically to Self-Generation mode and acts as a regular HSM unit, until the GPS recovers.
Typical GSU Scenarios
Independent Distributed Sites
In the scenario of Figure 11-1, we have multiple independent collocated sites, which may
interfere with each other. To meet this situation, we coordinate all of them using the GSU as
shown.
The GSU functions like “wide area HSS unit”, ensuring that all participating radios at the locations marked GSU each transmit and receive at the same time.

Figure 11-1: GSU Scenario - Independent distributed sites
Multiple Distributed Sites with Communication
What happens if, in Figure 11-1, the GSU towers themselves have radios communicating as
shown in Figure 11-2?
Consider GSU 1 and GSU 2: Both collocated towers transmit and receive simultaneously. However, the radios communicating at GSU 1 and GSU 2 must transmit and receive in turn according to the scheme in marked “Normal Phase” in Figure 11-3. This is an impossible situation,
if all the links must send and receive together. It is further complicated by adding a third and
further sites as shown.

Cascaded Sites using Shifted Phase Transmission
Chapter 11
Cascaded Sites using Shifted Phase Transmission
The solution offered here is not a “universal cure”. The following conditions are necessary, but
in any specific case may not be sufficient:
•
The GSU sites (marked 1, and 3 above) are sufficiently far apart as to ensure that
there is no mutual interference between communicating sites (1-2 and 2-3 above)
•
There should be no interference between non-communicating sites (1 and 3 above).
To see how it works, we use Figure 11-2. The GSU towers are numbered and marked for
cascading, 1-2 and 2-3. There should not be a link between 1 and 3.
The GSU can synchronize the TDD timing of several sites enabling the cascading of consecutive links without mutual interference.
To use cascading, the TDD timing of the even-ordered links (GSU 2 above) must be “shifted”
(Shifted Phase) and odd-ordered links (GSU 1 and GSU 3 above) must be “unshifted” (Normal
Phase). The phase shift is half of the Radio Frame Duration (RFD) from the chosen RFP. The
scheme is shown in Figure 11-3.
Since the GSU is always HSS master (HSM), at each GSU location, the GSU can “force” the
synchronization of its collocated radios. By half RFD shifting, alternate collocated sites can
talk to each other.
Figure 11-3: Phase shifted transmission - phase shift is 1/2 the RFD
Choice of normal or shifted phase is configurable per GSU using the RADWIN Manager.
GSU Redundancy
The GSU is designed to support redundancy, improving the robustness of a GSU based topology.
In redundancy mode, two GSUs are installed at the same HSS site. One of them self-configures to generate HSS sync signals. We will call it the Primary unit. The other one, the Secondary unit remains dormant merely polling the first GSU. If the Primary GSU fails, then the
Secondary GSU becomes active immediately. If the Primary unit becomes active again, it
remains dormant, reversing the original roles. The choice of the Primary GSU is random and
of no significance.
If the Primary GSU fails, and then the Secondary GSU also fails to receive sync signals from
its GPS, then it moves to self-generation HSM mode like an ordinary HSM ODU until its GPS
recovers.

Preparing the GSU for Use
Chapter 11
Figure 11-5: General GSU configuration
In that respect, all of the considerations of Chapter 3, Chapter 17 and Chapter 18 of the
use Manual apply to the GSU.
It may be configured using the regular RADWIN Manager or Telnet.
Preparing the GSU for Use
Use the method of Chapter 19, Preloading an ODU with an IP Address to change the IP
address from the default (10.0.0.120). In the example screen captures below, we use
192.168.222.20 with Subnet Mask 255.255.252.0.
Mounting the GSU
Mount the GSU and antenna. Ensure that its ODU port connected to its PoE device and the
HSS cable is connected to the HSS unit as shown. The external LAN port of the PoE device is
connected to the managing computer. If you are accessing the GSU through a network it is
essential that you use the IP preloading method. The default IP address may be inaccessible
and you may not use the Local Connection method over a network.
Configuring the GSU
Getting Started
To configure the GSU, you log on to it, exactly as in Chapter 4.

The Status Box
Under normal operating conditions, it will be green as shown, indicating that it is synchronized with a satellite.
If satellite synchronization is lost, then the GSU will function as an independent HSM and the
status box will change color:
The Main Menu
The main menu is a subset of the main menu applicable to the WinLink 1000. Notice that
there are no Installation or Configuration wizards. Such configuration as is necessary is carried out using a modified version of Site Configuration for WinLink 1000.

The GSU is automatically configured as HSS Master (HSM).
Ensure that no other collocated ODU is configured as HSM.
Note
If the hub site consists only of WinLink 1000 units, then any suitable RFP may be chosen.
If there are one or more RADWIN 2000 units, you must use RFP B or E.
