1 INTRODUCTION

The following document describes the required actions that must beperformed before installing the WALKair V3.1 system.

• Mechanical Requirements

• Environmental conditions

• Electrical Requirements

This information, as well as a site survey, must be obtained prior toinstallation of the BS and the TS. It is recommended that personnel familiarwith the site, for example, the building superintendent, accompany the sitesurveyor. Where multiple BS-BUs are to be installed, copy the relevantsections of this document for the specifications required.


Elevated voltages are present at specific points in this electrical equipment.Some of the parts can also have elevated operating temperatures. Non-observance of these conditions and safety instructions can result in personalinjury or in property damage.



• EN 50081-1

• EN 55022

• IEC 100-4-as2, 3, 4, 5, 6, 8, 11

• ETSI 300339


Page 1-2 P/N 110502-01 REV 1.1

To avoid injury and prevent equipment damage, observe the following safetyprecautions:

• Do not move or ship equipment unless it is properly packed in its originalwrapping and shipping containers.

• When connecting equipment to the AC and DC voltage supplies, ensurecorrect polarity.

• Equipment service and maintenance should be undertaken only byWALKair V3.1 trained personnel.

• Ground the system units to prevent damage by lightning.

• Do not permit unqualified personnel to operate workstations used tocommunicate with the system.

1.2 Components Sensitive to ElectrostaticDischarge

All units that carry the Electrostatic Discharge sign (ESD), containcomponents sensitive to ESD and must comply with the necessaryregulations (see Figure 1-1).

FIGURE 1-1: ESD GRAPHIC SYMBOL

For units carrying the EGB symbol that are packed, unpacked, handled,extracted, or inserted, grounding brackets must always be worn. This ensuresthat the units are not damaged (see Figure 1-2).

WALKair V3.1 IMN Site Survey Guide

P/N 110502-01 REV 1.1 Page 1-3

FIGURE 1-2: EGB GRAPHIC SYMBOL

ESD

• An appropriately labeled grounding socket for the grounding-bracket plugis provided on the right-hand side-securing flange on every subtrack.

• Every PC board has a grounding edge around the outside that isconnected to the “ground” of the plug-in unit by which the board can behandled.

• Contact with the component terminals, the contacts of the SIEDECONconnecting strip and the conductor tracks must be avoided.

• Units located in shielded, closed housings are protected in all cases.European standard EN50082-1 provides information on the properhandling of components that are subject to electrostatic discharge.

1.3 Additional Safety Requirements• When fitting and removing units as part of installation and maintenance

work, the attached insertion and extraction aids must be used.

• DC cable shield must be connected to ground on both sides. Provide asecure connection to the BU case via the D-Type connector.

• Powering off the indoor units is performed by disconnecting the DCpower supply cable.

• When disconnecting the DC power supply cable from the MainDistribution Power, disconnect first the +/- 48V supply and onlyafterwards disconnect the shield.

• E1 output cables should be installed within the same building as theBase Station's BU.

3 FREQUENCY SURVEY

The Frequency Survey provides a radio data base needed for properoperation of the system.

3.1 Equipment for Radio Survey• Spectrum analyzer

• RF amplifier with power supply

• 60º BS antenna

• RF cable suitable for the frequency band

• Plotter

3.2 Frequency and Interference Mapping

Frequency RangeSelected FrequencyBand

3.5 GHz ! 10.5 GHz ! 26 GHz !

3.3 Spectrum Images

• The polarization of the antenna should be obtained for the verticalposition

• Use the MAX HOLD feature to provide full coverage

• At the BS, a cover area of 360 degrees is required.First capture the proposed operating area of the antenna, and then rotatethe antenna through the required 360 degrees.

• At the TS, a cover area cover of 180 degrees is required.

• Two images are required for every angle. One with a maximum RBW(Resolution Bandwidth) of 2 MHz., and the other with a minimum RBW of1 kHz. The sweep time should be no greater than 50 ms. The VBWshould be in the same position as the RBW.

• The observation span at the BS site will be the uplink band and thedownlink band will be at the TS.

Chapter 3. Frequency Survey

Page 3-2 P/N 110502-01 REV 1.1

• Check for additional interference by changing the polarization of theantenna and the RBW.

• Repeat the above steps with the antenna in the horizontal position.

3.3.1 RF Chain

The RF Chain enables accurate detection of radio frequency interference andis a recommended tool for the Radio Survey. Due to the poor sensitivity of thespectrum, a spectrum analyzer cannot be connected directly to the antenna.To improve the sensitivity of the spectrum, place the following componentsbetween the antenna and the spectrum analyzer (see Figure 3-1):

• Low-Noise Band-Pass Filter

• RF Amplifier

• RF Amplifier Power Supply and Cable

Figure 3-1 illustrates the RF Chain components, Table 3-1 lists the RF Chaincomponents and their settings.

2 SITE PREPARATION

This section presents a description of the site preparation requirements,prior to installation of the WALKair V3.1 system.

TS site preparation should proceed in the following order:

1. Installation of the antenna mast (by installer)

2. Grounding the Mast

3. Install IF cable

2.1 Housings, Mountings, Dimensions andClearance

TS-BU units can be installed in the following:

• Standard 19" or ETSI racks

• Wall mounted

• Desk mounted

Width = 44 cm (19”)

Height = 1U (4.4 cm)

Depth = 23 cm

Weight 3 kg.


Page 2-2 P/N 110502-03 Rev 1.1

2.2 IF Cabling

A single coaxial cable (type LMR400 recommended), connects the outdoorequipment to the indoor TS-BU with an attenuation not greater than 20 dB.

Prepare all cabling prior to installation. Cable length and attenuation permeter should be determined prior to cable connection. Cable length is thedistance between antenna mast and TS-BU.


• Type of Cable

• Cable Length

• Attenuation per meter vs. frequency of the cable

2.3 Powering and Earthing

To prevent damage to the equipment, ensure that grounding cables areconnected to the Antenna/RFU.

Power is supplied to the TS-BU only, from an external power supply. Useeither a 110/220V AC or -48V DC power source.

Ensure that a separate grounding line is provided for the installedequipment and grounded to a central grounding point.

P/N 110502-03 Rev 1.1 Page 3-1

3 INSTALLATION

3.1 TS Installation Overview

The installation of the TS includes four main steps:

• Mounting the outdoor equipment

• RFU/Antenna alignment

• Installing the indoor equipment

• IF cable connector assembly and performing cable DC testing

• Supplying power to the TS-BU and verifying that the LEDs are lit

• Sealing ODU RF connectors for water resistance

3.2 General Tips For RFU-TS Installation• Never install the RFU near power lines.

• Assemble the RFU, bands and mounting adapter in a safe locationbefore climbing up to the mounting location. Use caution whenclimbing, and when working at the mounting location.

• Make sure you have determined the best location for the RFU polebefore mounting the pole. Make sure that you can route the IF cablefrom the location into the building.

• Before drilling any hole at the site building, make sure there are noelectrical wires in the area of the holes.

• All installations should conform to the local building and electricalcodes. If you are not sure, contact a licensed building inspector orelectrician in your area to assist you. Be aware that communityconventions, if any, may have additional requirements. Also, checkyour homeowner’s insurance policy for any restriction or expectationsthat may apply.

• Choose a location that is easily accessible in most weather conditionsfor proper maintenance.

• Consider seasonal changes. The location may appear clear in thewinter, but spring and summer foliage could dramatically attenuate thesignal.

• Do not install the RFU at the top of the pole; always leave at least40 cm space between the top of the pole and the RFU for betterlightning protection.

• Do not install the RFU where it can be blocked by people.

• The RFU and antenna must have a clear line-of-sight to the BaseStation. The RFU must be mounted so that the line-of-sight is clear ofneighboring buildings, trees, power lines and other obstructions. If you

Chapter 3. Installation

Page 3-2 P/N 110502-03 Rev 1.1

are mounting it on the middle of the roof, we recommend to install theRFU-TS at least 2 m above the lowest roof line (for example, the lineof the railing can be taken as a reference line), make sure that thereare no walls or blocks in front the RFU on the roof. If you need tomount the RFU on the wall of a building you must ensure that theRFU-TS will be at least ½ m away from the wall and no less than 15 mhigh from the ground.

• We recommend installing the RFU-TS at the corner of the roof 1mabove the railing and no less than 15 m high from the ground. Ifconditions exist that do not match the rules of a specific area theninstall it according to the above paragraph description(see Figure 3-1).

radius required from the center of the beam and the obstacle versusdistance between the Terminal and the Base at 3.5 GHz systems.Figure 3-2 illustrates a schematic graph of the clear line of sight zone asdescribe above.

NOTE

Some time it may be difficult to determine line-of-sight because of yourvantagepoint.

In this case you can estimate if the obstacle is in the radius or not byestimation scales and references obstacle dimensions or by measuring itaccording to the maps

Possible interference:Generally, large reflecting surfaces in parallel or partly in the beam willcause reflections of the radio signal. For example, a metal/glass building,moist earth, water, and above ground metals like poles and telephonelines. If you have a clear line-of-sight as defined above the effect of thisinterference's will be minor.

The customer is responsible for ensuring that the preparations arecomplete and in accordance with national, state, and local codes.

Antenna alignment:In the 3.5 GHz systems, the AZIMUTH alignment of the antenna can bedone effectively using a compass and maps. Before you align the antennawith a compass you should be aware of deviation and declination errorscaused by magnetic objects and shifting of the real north magnetic filedrespectively. The deviation error can be avoided by ensuring that magneticobjects are located a safe distance away from the compass. Objects thatcause magnetic deviation include those containing steel, iron, or electricalcables with strong current. The declination problem can be avoided byusing a compass with declination adjustment and local maps with precisevalue of declination. According to this problem the compass calibrationmust be preformed before initial use to be accurate.

3.3 Mounting the 3.5 GHz or 10.5 GHz TS Antenna

3.3.1 3.5 GHz or 10.5 GHz RFU/Antenna

The 3.5 or 10.5 RFU/Antenna is mounted on a mast with adjustablemounting grip and bands. The front panel of the TS RFU (i.e., the side notattached to the mounting adapter) is designed to prevent accumulation ofrainwater, which would cause damage to the unit. The mounting adaptercan be oriented in any direction relative to the pole (i.e., 90o, 180o, 270o,and 360o). Before attaching the RFU to the mounting adapter, make surethat the connector is pointing downward.

3.5 IF Cable Connections

The indoor mounted TS-BU has front panel connection points for easyaccess to all interfaces. A single coaxial cable connects the indoor TS-BUto the outdoor unit. See Table 3-5 and Figure 3-18 for details about theTS-BU interfaces.

It is recommended that the cable length be prepared prior to installation. Inaddition, cable length and attenuation per meter should be determined,prior to cable connection.

WARNING!

A short test must be performed on IF cable connectors prior to IF Cableconnection to the equipment. Failure to do so can result in damage to theTS-BU. See Figure 3-12 for testing.

FIGURE 3-12: CONNECTOR SHORT TESTING

IF Cable

NOTE

1. If a short is present in the cable, the cable must be repaired orreplaced.

2. Upon entering a building, leave a drip loop so that water will not followthe cable inside. If the cable lays on a roof or the ground, protect itwith a conduit to guard against crushing. An electrical test should beperformed. After the test, waterproof all outdoor fittings, the groundconnections, and the cable entry points into the building.


Page 3-16 P/N 110502-03 Rev 1.1


• Cable length

• Attenuation per meter of the cable Vs frequency (600 MHz – 1.8 GHz).This can be determined by using a cable data sheet.

3.5.1 RFU/Antenna Cable Connections

The TS RFU/Antenna is connected to the TS-BU by a single coaxial cableas described in Table 3-4. Table 3-4 details the point-to-point cableconnection.

TABLE 3-4: RF CABLE INTER-CONNECTION

CABLE FROM TO NOTE

COAX LMR400(Recommended cable)

Ant/RFU TS-BU Maximum 150 m

• For cable lengths greater than 150 m, use a higher quality cable thanthe LMR400. Total cable attenuation must not exceed 20 dB,regardless of cable length.

NOTE

• The IF cable connector must be a certified outdoor connector.

• The outdoor connectors should be tightened using sleeves.

• After installation, all outdoor cable connections must be sealed withwaterproof materials

NOTE

When routing the coaxial cable, leave a service loop at the antenna sothere will sufficient length of cable to replace a faulty connector, whennecessary. Secure the coax so that there is no mechanical stress at theantenna connection. Follow the super structure with the cable to its baseto the building. If the cable requires suspension from the base to thebuilding, use a stranded wire to support the cable weight. (The support willprevent a migration of the cable's inner conductor to the shield).
