Components of a RADWIN 5000 SCB Jet Link or Sector Introduction
2.2 Components of a RADWIN 5000 SCB Jet
Link or Sector
2.2.1 Major Components of a PtMP Sector
A RADWIN 5000 SCB Jet Point-to-MultiPpoint sector consists of an HBS communicating with
up to 4 HSUs located within the beam of its antenna.
Figure 2-1: Sector Schematic: Main Components
Both the HBS and the HSUs communicate respectively, with the service provider and users
through PoE devices. The communication protocol for both the service provider and the
users is Ethernet.
Extended radial coverage can be achieved by setting up adjacent sectors using co-located
HBSs.
HBSs connected through a switch satisfying the following requirements
may be co-located at one site:
• L2 Managed Switch
• Must support GbE
• Does not support EEE (Energy Efficient Ethernet), or
• If it does supports EEE, it should be according to the IEEE 802.3az
standard

RADWIN 5000 SCB Jet User Manual Release 4.2 2-4
Major Components of a PtP Link Introduction
2.2.2 Major Components of a PtP Link
A RADWIN 5000 SCB Jet point-to-point link consists of a pair of outdoor radio transceivers
units (ODUs) using a MIMO 2x2/3x3, OFDM smart beam-forming integrated antenna. The
ODU itself is connected to a PoE device providing an Ethernet LAN connection to user
equipment.
2.2.3 Accessories
To build a SCB Jet link or sector you will require some of the following accessories:
•PoE devices
•Suitable L2 Switch for a co-located hub site (if using HSS Over Ethernet (HSSoE))
•ODU mounting kits
•Lightning protectors
•Ethernet repeaters
•CAT 5e cables of various lengths
•Grounding cables
2.2.4 Management Tools
RADWIN Manager
The RADWIN Manager is an SNMP-based management application which manages a
complete sector over a single IP address. It can also manage HSUs separately.
Other third party Element Managers may also be supported.
RADWIN Web Interface for Management
The Web Interface enables you to carry out basic link and sector management functions
using a Web browser.
It may be used to -
•Establish a link or sector on a minimal basis
•Check link parameters and make basic changes
•View the ODU Inventory
•Inspect the Recent Events logs
Full details are supplied in PtP: Using the Web Interface and PtMP: Using the Web Interface.
The release of the RADWIN Manager supplied with the SCB Jet series
cannot be used with earlier RADWIN radio products.

Chapter 3: Site Survey
3.1 Planning the Sector or Link Sites
3.1.1 Overview
This chapter relates primarily to planning Sector sites. For practical purposes, a Link Site
Survey may be treated as a Sector Site survey for one HSU. Obviously the numbers will be
different reflecting different throughputs for the two cases, however the Surveys will follow
the same procedure.
Sector site planning consists of a set of surveys, which must be carried out before any
equipment is deployed. If for some reason, the outcome of any of these surveys is negative,
HBS or HSU re-location will need to be considered.
A Site Survey consists of three stages:
1. Preliminary survey - The proposed sector is analyzed in the office using a topographic
map. You should use additional tools such as the RADWIN Radio Planner.
2. Physical survey - The locations of the indoor and outdoor equipment are determined on-
site.
3. Radio Frequency (RF) survey - It is recommended that the installation area be scanned
with a spectrum analyzer, to identify RF interference so as to determine a clear channel
for radio installation (on-site).
3.2 The Site Survey
3.2.1 Introduction
RADWIN wireless links must be planned before installation. The designated installation sites
must be appraised to determine that the wireless system is able to operate efficiently and
provide connectivity without signal degradation.
RADWIN 5000 SCB Jet offers a wide operating frequency range. A free frequency channel
must be determined within the operating range, for optimum performance.

•Communication devices (for example, cellular phones, or a set of walkie-talkies)
3.3 Stage 1: Preliminary Survey
A preliminary survey is necessary before visiting potential installation sites. As much detail as
possible should be obtained about the designated ODU installation sites and the area
between them.
To perform a preliminary survey:
1. Mark the 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 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
a sector.
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 sector sites may dou-
ble the required antenna height.

Stage 2: Physical Survey Site Survey
5. Determine and record the compass bearings between HBS and the HSUs, relative to
north.
6. If there are obstructions between the two sites, calculate the Fresnel Zone
7. If the sites chosen do not meet requirements, consider alternative sites.
8. You may require a RADWIN Site Survey Kit to complete the task. Contact Customer
Support for further information.
3.4 Stage 2: Physical Survey
The physical site survey reviews the environment of the proposed installation location, to
ensure that the sector sites are suitable for the wireless network. The results of the physical
site survey should be recorded.
In what follows, ODU may be an HBS or an HSU:
To perform a physical survey:
1. From the compass readings taken in the preliminary survey, find the azimuth (hori-
zontal position) that each HSU should face towards the HBS.
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 ODUs (having regard for existing rooftop
installations and tower space). They should be above any obstructions, considering
the Fresnel zone.
4. If you need to install any type of ODU on a tower, make sure that the tower is far
enough from overhead electric power lines.
5. Determine a location for the indoor equipment; it should be as close as possible to
the ODU. At an existing site, there is probably an equipment room with cable-
routing channels.
6. Measure and record the path length of the cable from each ODU position to the
indoor equipment room.
It is advisable to go on a clear day, so you can more easily see any
obstructions between the two sites.

Additional Outdoor Site Requirements Site Survey
7. Determine the ground and lightning connection points of the installation. The ODU
and PoE 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
3.4.1 Additional Outdoor Site Requirements
The ambient outdoor operating temperature should be -35 to 60C (-31 to 140F).
3.4.2 Additional Indoor Site Requirements
The ambient operating temperature should be 0 to 50°C (32 to 122 °F) at a humidity of up to
90%, non condensing
3.5 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 each of the proposed sector 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.
3.6 RF Planning for Dense Installations and Co-
located Sites
Interference may arise from
•Self-interference from co-located RADWIN radios
•Other co-located radio devices installed on the same site.
To avoid or minimize interference, follow these recommendations:
•For co-located RADWIN units, use Hub Site Synchronization to synchronize between
them.

Additional Tools and Facilities Site Survey
•If one or more co-located units are not RADWIN units, ensure that there is a physical
separation of at least three meters between a RADWIN unit and any other co-located
radio on the site.
•Use the largest possible frequency gap between these units
•Choose the best frequency channel (as clear as possible from interference). You may be
able to change the band used for the sector - depending on HBS model and regulations.
•Decreasing the Tx Power of a sector will reduce collocation interference

3.7.1 RADWIN Site Survey Kit for Small Cell Backhaul
The process in Stage 2: Physical Survey can be carried out more easily using the RADWIN Site
Survey Kit. This kit includes an HSU ready for use in the field. The radio is mounted on a high
precision tripod. The radio, based on the technology described in this Manual, has an
integrated antenna, a rechargeable battery pack and a WiFi port to communicate with a
tablet also mounted on the tripod. The Tablet is pre-loaded with the RADWIN Manager, as
well as the WINTouch application, which enables you to perform alignment and to conduct a
series of RF and performance tests. It is intended for use in a high-interference urban
environment under nLOS or NLOS conditions.
