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.
Conventions Used in this Manual Chapter 1 Conventions Used in this Manual Notifications Notifications consist of Notes, Cautions and Warnings.
Windows Terminology Chapter 1 Figure 1-15: Menu navigation in the RADWIN Manager Similarly, mouse click items will be referred to like this: “Click Next to continue.” (A mouse click always uses the left mouse button unless stated otherwise.) Windows Terminology Look at Figure 1-1 above. The main application display which you see consists of a framewindow with a menu bar, system icons and content. It will be referred to as a window, the main window or the Manager window depending on context.
Viewing and Printing Chapter 1 Figure 1-16: Site Configuration window with open Management panel Viewing and Printing This manual is optimized for viewing online as a PDF file. To this end it uses an 11 point Tahoma typeface for main text. Tables for most part, use 7 or 8 point fonts. Here are a few pointers for hard-copy printing: • The text and table typefaces used are large enough to print the manual at two pages per sheet • For good legibility, use a commercial grade laser printer.
Chapter 2 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.
Stage 1: Preliminary Survey Chapter 2 • 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 Surve
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.
Stage 3: RF Survey Chapter 2 • For IDU-C units, allow at least 90 cm (36 “) of front clearance for operating and maintenance accessibility.
RF Planning for Dense Installations and Collocated Sites • Chapter 2 Decreasing the Tx Power of a link will reduce collocation interference (Site Configuration | Air Interface).

Secure the site A antenna to the pole/wall. 9. Repeat steps 4 to 8 for site B.
Chapter 4 Getting Started with the RADWIN Manager Installing the RADWIN Manager Application Minimum System Requirements The RADWIN Manager application is distributed on a CD.
Getting Started with the RADWIN Manager Chapter 4 ? 2. Choose Install RADWIN Manager and follow the on-screen instructions of the installation wizard to complete the setup of the RADWIN Manager application. If the installation program fails to start, browse to your CD/DVD drive, chose the setup.exe program and run it. Getting Started with the RADWIN Manager If your links are within easy reach, you can configure them using the procedure described below.
Getting Started with the RADWIN Manager Chapter 4 Figure 4-1: LAN ports on the front panel of the IDU-C For IDU-E users: The LAN ports are located on the rear panel on the unit. Note If you are not using a direct connection as above, ensure that you have IDU to managing computer connectivity (e.g. through a LAN). 2. Check that you have connectivity to the ODU. You can do this by opening up a command line session (Start|Run and then type, cmd). At the command prompt, type ping 10.0.0.
The RADWIN Manager log-on Concept Chapter 4 Figure 4-3: First time log-on window The RADWIN Manager log-on Concept The RADWIN Manager provides three levels of access in one of two entry modes. To see them, click Options at any time in the Log on window (Figure 4-3 above). You are offered an extended log-on window: Figure 4-4: Extended log-on window Note Connection through the RMNS Sever will be available in a future release.
The RADWIN Manager log-on Concept Chapter 4 Figure 4-5: Log on window exposing the user types. There are three user types: • An Observer has read-only access to the link. An Observer can monitor the link, generate reports, but may not change any link parameters. • An Operator can install and configure the link. • An Installer can, in addition to functioning as an Operator, also change the operating band. The latter function has legal ramifications, requiring familiarity with local regulations.
Log-on Errors and Cautions Chapter 4 • If you log on using Local Connection, but your physical connection is not local (i.e. anything other than a direct connection between the managing computer and the IDU), then any configuration you carry out may affect other links in the network. Do not do this! • • Network log on (IP address to the ODU) is recommended. If you log on via an over-the-air IP address, you will receive a warning.
Incorrect IP Address Chapter 4 Figure 4-6: Unsupported device message Incorrect IP Address If the IP address chosen is invalid or the link is unreachable, the following error message will be displayed: Figure 4-7: Unreachable device message In both of the above situations, if you click No, you will see a warning graphic the IP Address field. alongside Incorrect Password If you type an incorrect password in the Login window, you will see a warning graphic alongside the password field.
Continuing without an IP Address Chapter 4 Figure 4-9: Logging on to an over-the-air site Continuing without an IP Address The RADWIN Manager provides limited “offline” functionality when there is no accessible IDU/ODU. It is primarily for setting managing computer related parameters, running the Link Budget Calculator or viewing online Help. The offline functionality is shown in Table 4-3 below. The table does not show menu items grayed out.
First steps Chapter 4 2. Enter the current password, and the new password. Note A valid log-on password must contain at least five characters excluding SPACE, TAB, and any of “>#@|*?;.” 3. Click OK to confirm. First steps For what follows, it is assumed that you have set the IP addresses of both ODUs. For the purposes of illustration, we will use the following IP 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.
First steps Chapter 4 The Dynamic Tx Ratio bar only appears for model RADWIN 2000 C 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.

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.
Installation Chapter 5 The air rates used in this mode are same as when using single antennas in both sites.

RADWIN 2000 Broadband Wireless Transmission System USER MANUAL RELEASE 2.5.40 Part 2: Site Synchronization UM 2000-2540/02.
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.
What is Hub Site Synchronization? Chapter 10 Figure 10-1: Interference caused by collocated units 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.
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.
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.
Using More than One HSS Unit Chapter 10 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.
HSS Error Notification Chapter 10 Figure 10-8: Cascading three HSS units 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.

RFP: General Radio Frame Pattern Chapter 10 Figure 10-10: Radio Frame Pattern Five RFP types (A to E) are available. Under HSS the RFP must be configured by the user depending on the type of the radio products, services and channel bandwidth in accordance 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.
RFP: RADWIN 2000 Considerations Chapter 10 • 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.

Chapter 11 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.
Multiple Distributed Sites with Communication pendent dis Chapter 11 tributed sites 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.
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).
GSU Kit Contents Chapter 11 Figure 11-4: Make the GSUs the first two collocated units Redundancy switching is completely transparent to the GSU-managed links. GSU Kit Contents The GSU package includes: • 1 x GSU • 1 x Mounting Kit • 1 x GPS Antenna • 1 x GPS Antenna Mounting Kit • 1 x RF Cable, 1.5m • CD GSU Installation Overview The GSU uses the same container and cabling as a WinLink 1000 unit. RADWIN 2000 User Manual Release 2.5.
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.
Configuring the GSU Chapter 11 Figure 11-6: GSU Main widow at startup The top five items in the GSU Monitor panel are taken from a satellite. The transmission Phase may be Normal as shown or Shifted. It purpose, together with the Tx Ratio bar, will be explained below. The Status Box Under normal operating conditions, it will be green as shown, indicating that it is synchronized with a satellite.
