The indoor units must be connected directly to the DC Supply System grounding electrode conductor

All indoor equipment in the immediate vicinity must be grounded in the same way, and not be grounded elsewhere

The DC supply system is to be local, i.e. within the same premises as the indoor equipment

There shall be no disconnect device between the grounded circuit conductor of the DC source (return) and the point of connection of the grounding electrode conductor

Ensure that outdoor units, antennas and supporting structures are properly installed to eliminate any physical hazard to either people or property

Verify that the installation of the outdoor unit, antenna and cables is performed in accordance with all relevant national and local building and safety codes

Even where grounding is not mandatory according to applicable regulation and national codes, it is highly recommended to ensure that the outdoor unit and the antenna pole (when using external antenna) are grounded and suitable lightning protection devices are used so as to provide protection against voltage surges and static charges

In any event, Alvarion is not liable for any injury, damage or regulation violations associated with or caused by installation, grounding or lightning protection

The Base Station includes devices that can be damaged by accidental introduction of ground or foreign voltages etc

An electrostatic discharge on a component at a voltage exceeding 600 volt is sufficient to damage the component, even if mounted on a board

WARNINGDue to ESD, Electronic boards must be stored in anti-static envelopes or inside packages, during transportation and storageIt is recommended an anti-static bracelet connected to ground via protective resistance to avoid circuits damage when handling printed circuits

All electronic components are subject to ESD electrostatic discharges

Electrostatic discharges at voltage ratings below 4000 volts are not normally detected or perceived in any other form by the persons causing the actual discharges

For example, the natural movements of a person wearing synthetic clothing may generate electrostatic voltages exceeding 10,000 V!

Components are damaged by an electrical break in the ultra-thin insulating layer in the integrated circuits (measuring typically 0.0001 mm)

The damage may be serious and cause the immediate function failure or remain latent and occur later, only after a certain time span has elapsed, which could also be several years!

The ODU can be either pole/tower or wall mounted

Its location should enable easy access to the unit for installation and testing

Outdoor units with a connection to an external antenna should be installed as close as possible to the antenna

The antenna should be positioned in such a way that the coverage will not be affected by environmental conditions of the roof or house on which it is installed

For instructions on installing the antenna, refer to the manufacturer’s installation instructions provided with the antenna

The higher the placement of the antenna, the better the achievable link quality

The antenna of the Access Unit should be installed so as to provide coverage to all Subscriber Units within its service area

The recommended minimum distance between any two antennas is 0.5 meters

The antenna should be installed to provide a direct, or near line of sight with the coverage area

When the BS antenna is installed outside the boundaries of the roof

The minimum distance between the antenna and the railing or building side is 25 cm

The angle between the antenna and the roof is 22 degrees

When the BS antenna is installed on a pole on top of the railingThe antenna is not blocked by anything on the roof, or on adjacent roofs

It is essential to maintain a minimum distance of 1.5m between the lower part of the antenna and the top of the roof, fence or railing, whichever is closer to the antenna

When the BS antenna is installed on a pole and the pole is installed towards the center of the roofThe antenna may be blocked by objects on the roof or by the railing or fence

It is essential to maintain a minimum distance between the lower part of the antenna and fence or railing, in order to minimize disturbance of the antenna’s lobe

The distance to the roof’s floor and the fence depends on the distance of the antenna from the railing

The farther the horizontal distance of the antenna from the raising, the larger the vertical distance

Use the following formula to calculate the heat dissipation for each Base Station:

[(Module 1 power consumption) + (Module 2 power consumption) + … (Module N power consumption)] x 2.3884 = BTU

For example, for a Base Station with 1 AU and 1 NPU (and no redundancy), the heat dissipation is as follows:

[(PIU = 30 Watt) + (PSU = 200 Watt) + (NPU = 65 Watt) + (AU-IDU = 41 Watt) + (AVU = 24 Watt)] x 2.3884 = 860 BTU

The Outdoor Unit can be mounted on a pole using one of the following options:

Special brackets and open-ended bolts are supplied with each unit.

There are Two pairs of threaded holes on the back of the unit, enabling the special brackets to be mounted on diverse pole widths

The grooves on the topsides of the unit and a protrusion on the bottom (back side) enable the use of metal bands to secure the unit to a pole

Note: The bands should be 9/16" wide and at least 12" long

Installing an outdoor unit on a pole, using the brackets and open-ended bolts

Insert the open ended bolts with the grooves pointing outward, as these grooves enable you to use a screwdriver to fasten the bolts to the unit

A distance of at least 0.5m is required between two neighboring ODU

Identify a reference point on the landscape that is in the direction of the heading of the Base antenna

Depending on whether you are looking from the left or the right side of the antenna, add or subtract 90° to/from the Base Station azimuth

Using the compass, align the outer frame of the antenna to the newly calculated azimuth, so that the flat surface of the antenna faces the reference point. This reference point is 90° to the Base antenna heading

When aligning the antenna on top of a tower, don't align using a compass when you are on top of the tower, due to the fact that the tower interfere with the magnetic field of the compass

True North definitionnavigational term referring to the direction of the North Pole relative to the navigator's position

Magnetic North definitionthe point where the geomagnetic field points vertically downwards, i.e. the dip is 90°, was proposed in 1600 by Sir William Gilbert, a courtier of Queen Elizabeth I

Due to the fact there is a difference between these two points, Variations is defined as the angular difference between thesetwo directions

The compass is always referring to the Magnetic north while a GPS can point either to the True north or to the magnetic north depends on the GPS type and configuration

After aligning the antenna check within 100m from the BS (in the direction of the middle of the antennabeam width) that the direction of theBS from your point is 360º - (BS antenna direction)º
