CHEKING THE EQUIPMENT

GENERAL

MICROWAVE WORLD

Today in the hi-tech world we use more & more in wireless.

The microwaves provide us solution to supply information from point to point.

The microwave provides us solution to:

1 .Mountains.

2 .Roads.

3 .Trees.

4 .Sea.

This is jest same of the list but, not all is good in the wireless microwave.

The microwave have disadvantage to example:

1 .Many mechanical faults

2 .Weather.

Why we use in microwave & not in optical fiber?

First because not always we can use with optical fiber.

Second microwave is cheaper.

Background

The nokia flexihopper microwave radio is available to 7, 13,15,18,23,26, 38 and 58 GHz frequency band.The radios indoor and outdoor units are connected together with a flexbus.The flexbus is a signal coaxial cable, which carries all the signals between indoor and outdoor units.It also carries the power to the outdoor unit.The distance between indoor and outdoor unit can be up to 300 meters.To long distance link we use in low band frequency and big antenna.To short distance link we use in high band frequency and small.Nokia flexihopper microwave radio support plesiochronous digital hierarchy (PDH) capacity of2x2, 2x4, 2x8, 2x16Mbps.The plus in nokia equipment is that we have the option to change the capacity without change the material.The change made by the software.

CHECK THE EQUIPMENT

To promise a quality work without errors we will check our self before and after the work.

We need to check before the installation that we have all equipment that we need to execute the work.

We check if the we have the correct antenna support with all the materials.

We check that we have the correct radio like the plane.

We check that we have the correct antenna like the plane.

We check that we have the correct indoor unit (FXCRRI or FIU) like the plane.

We check that we have enough RG223 cable.

We check that we have all the require tools.

We check that we have enough BNC and TNC connector

We check that we have enough reserve parts.

After we made all the checks we prepare to work.

This level calls risk management. From this point we know what expect us and we don’t be surprise in the middle of the work.

Installation

OUTDOOR UNIT:

The installation is one of the important levels if, the installation don’t be good we work more hard.

The first level in the installation is the planning.

The planning step is to bild the all installation in the head step by step. In this way we minimize the errors.

When we start the equipment installation is very important to tie the equipment in two places.

After we finish the antenna support installation we need to verify that the antenna support doesn't move.

Before the installation of the antenna we need to check the polarization and the type (frequency band & size) and if necessary, to change the polarization or the antenna.

The next step is to install the antenna. The antenna needs to be 90 degrees to the antenna support.

It will give us more tied antenna to the antenna support in this way we prevent any movement and we keep on stabile link.

Before the installation of the coupler we need to check the polarization and the type (frequency band) and if necessary, to change the polarization or the coupler.

If the antenna feeder is protected with a cover or tape, remove it before the installing the radio or the coupler.

Radio1 is always behind the antenna (more close to the antenna support) and radio2 is in front ofradio1.

The next step is to mark the flexbus cable in the edge and connect to the outdoor unit.

Connect the ground cable to the radios.

Bring the cables (ground & flexbus) in maximum 45 degrees down to the antenna support and from there tie (but not too much) & esthetic way without loops to the indoor unit.

Tight and sealed the connector in the radios.

Connect the ground cable to the base bar (MGB) in the bottom of the tower.

In antenna 1.2m & more we add azimuth bar to avoid any move from the antenna. The azimuth bar installation made after the alignment.

When we connect the azimuth bar to the antenna we need to connect multimeter & see that the signal don’t change and to check in the computer too.The azimuth bar needs to connect between the antenna & the tower in angle that will be maximum 20 degrees to avoid any movement from the antenna.

-4-INDOOR UNIT :

Indoor unit in nokia equipment is very unique because we have the option to change the capacity without change the unit.

There are number of kinds of indoor units:1 .FC RRI: indoor unit is fully integrated with nokia Ultra Site Bts. It provides a flexbus connection for one

outdoor unit.

2 .FXC RRI: indoor unit is fully integrated with nokia Ultra Site Bts. It provides flexbus connection for two outdoor units and full cross connection, loop protection grooming capability .

3 .FIU 19: compact 19'' indoor unit providing connection for up to four outdoor units depending on the configuration.

Nokia flexihopper microwave radio can be managed locally with:

1 .Nokia hopper manager (with FIU19).

2 .Nokia SiteWizard (with FC RRI and FXC RRI).

It can also be managed remotely from the nokia NMS.

The outdoor and indoor installation need to be esthetic.

Configuration

After we finish the installation we start the configuration. In the configuration we set all the parameters of the link.

The best way to do the configuration is with contact between the two sites and to set all the parameters in the same time.

If need more than one E1 do the same (depend on the plan).

After finish the cross-connection press send .

-19-Rx level indication :

When we start the alignment we have two ways to see what the Rx level is:

1. See the primary window under the antenna automatic refresh minimum each 10seconds.2. Enter to the script to see the Rx level every second. Follow the next steps.

In the main window go to tools → script tools → view → enter.

Go to FXC RRI → Measurements → Outdoor Unit 1→ Enter.

We get this window.

Picture 15

Rx input level see us the signal each press on refresh give us the signal in true time.

Because we don’t want always to press on the refresh we set auto refresh to 1 and click on refresh.

Now the signal will refresh automatically every second .

A lignment

The antenna have main gain and side gain is the alignment we get the main gain in both side of the antennas. If we get the side gain we don’t get the right Rx input level. In the alignment jest one antenna aligned and the

second antenna stand alone. Note never don’t aligned the both antennas in the same time .The fine- alignment of the antenna is performed after the transmit frequency has been set.The outdoor unit at the other end of the hop must be pre alignment to this station and must to send a signal with the correct frequency. After the both ends of the hop have been fine- aligned once, it may be necessary to repeat the alignment to get the best performance.When the antennas have been aligned for the radios at both ends of the radio hop, verify that the Rx input level

determined by the transmission planning is met .

Note: ALCQ must be off during the alignment. When we aligned

Check List

When we finish the alignment we need to check with ber tester the quality of the link.Because we don’t have ber tester we check that the fxc lamp is green.To promise quality link we to the next checks:

OUT DOOR UNIT INSTALLTION GOODNOT GOOD

check if all the require equipment exist      check if the antenna support install well(don't move, require height)      check if the radio in the field is match to the planning      check if the antenna in the field is match to the planning      check the antenna polarization      check that the rg-223 cable without loops      check if the azimuth bar support install in angle less then 20 degrees(in antenna 4fit or more)      check that the radio ground cable go in angle of 45 degrees to the tower(not more)      

check if the radio ground cable connect to the mob      check that the bnc connector is tight and seal      check if the antenna tight strong to the antenna support(after the alignment, see its not effective on the signal level)      check if the rg-223 cable mark(radio1,radio2)      check the agc level: radio1_______ radio2_______      check the Rx signal level: radio1_________ radio ________________      

INDOOR UNIT INSTALLTION GOOD
