1.2.2Electrostatic Discharge

The static electricity generated by human bodies may damage the electrostatic-sensitive

components on boards, for example, the large-scale integrated (LSI) circuits.

Human body movement, friction between human bodies and clothes, friction between shoes

and floors, or handling of plastic articles causes static electromagnetic fields on human bodies.

These static electromagnetic fields cannot be eliminated until the static is discharged.

To prevent electrostatic-sensitive components from being damaged by the static on human

bodies, you must wear a well-grounded ESD wrist strap when touching the device or handling

boards or application-specific integrated circuits (ASICs).

Figure 1-2 shows how to wear an ESD wrist strap.

leaned.

When installing or removing a board, note the following:

 Insert the board along the guide rails.

 Prevent the surface of a board from contacting the surface of another board. This is to

prevent the boards from being short-circuited or scratched.

 To prevent electrostatic-sensitive devices from being damaged by the ESD, do not touch

the circuits, components, connectors, or connection slots on boards.

1.2.4 Laying Cables

When the temperature is very low, violent strike or vibration may damage the cable sheathing.

To ensure safety, comply with the following requirements:

 Cables can be laid or installed only when the temperature is higher than 0℃.

 Before laying cables which have been stored in a temperature lower than 0℃, move the

cables to an environment of the ambient temperature and store them at the ambient

temperature for at least 24 hours.

 Handle cables with caution, especially at a low temperature. Do not drop the cables

directly from the vehicle.

1.3 Electromagnetic Field Exposure

Introduction

The Base Transceiver Station (BTS) emits Radio Frequency (RF) radiation. Follow the local

safety regulations when installing and operating the BTS to avoid radiation hazard.

Location of Base Station Antennas

Base station antennas, the source of the radiation, are usually mounted:

 On freestanding towers, with a height up to 30 m

 On a tower on the top of buildings

 To the side of buildings, on rare occasions

Generally, the antenna cannot be located in a position lower than 10 m. The energy usually

forms a horizontal main beam and is slightly tilted downwards. The remaining energy forms

into weaker beams on both sides of the main beam. The main beam, however, does not reach

the ground if the antenna is around 50–200 m away from the ground.

The highest level of emission would be expected in close vicinity of the antenna and in line of

sight to the antenna.

Exclusion Zones

The requirements for exclusion zones are as follows:

 The antenna should be properly located to prevent the public from accessing the area

where the RF radiation exceeds the previously mentioned limits.

 If areas with excessive RF radiation are accessible to the operation and maintenance

(O&M) personnel, ensure that they know the source of radiation and can power off or

shut down the transmitters before entering high radiation areas. In addition, such areas

must be confined within a distance of 10 m from the antennas.

 Each exclusion zone should be defined by a physical barrier and by a recognizable sign

warning the public or O&M personnel.

Guidelines on Choosing Antenna Sites

The guidelines on choosing the antenna sites are as follows:

 For roof-mounted antennas, raise the antennas above the height of the personnel who

may have to work on the rooftop.

 For roof-mounted antennas, keep the transmitter antennas away from the areas accessible

to the public, such as roof access points, telephone service points, and HVAC devices.

 For roof-mounted directional antennas, place the antennas near the periphery, and do not

make the antennas face the building.

 Consider the trade-off between large aperture antennas (lower maximum RF) and small

aperture antennas (lower visual impact).

 Keep higher-power antennas away from accessible areas.

 Keep the antennas in a site that is far away from urban areas, though this may contradict

the coverage area requirements.

1 Safety

1-12

Huawei Proprietary and Confidential

Issue (02)

 Exercise extra caution when designing co-location sites, that is, antennas owned by

different companies are located in the same site or are co-sited. This applies particularly

to sites that include high-power broadcast (FM/TV) antennas. Local zone often favors

co-location, but co-location may cause safety problems.

 Take special precautions for antenna sites near hospital and schools.

Location of BTS

The BTS is shielded from RF radiation hazards. The device has been tested to comply with

the radioactive spurious emission requirements of international standards or local regulations.

Therefore, the BTS under normal operating conditions does not cause danger to the public and

O&M engineers. However, the limits for RF radiation might be exceeded due to faulty

antenna cables or for other causes.

 BTS sites shall not be accessible to the public. Only authorized and trained personnel can

access BTS sites or equipment rooms.

 A sign of excessive RF radiation must be present on the doors of the sites or equipment

rooms to warn the personnel inside the site or equipment room of excessive RF radiation.

 BTS sites must be regularly monitored and inspected after installation.

Prediction of the Exposure to Electromagnetic Fields

This section provides a theoretical approach to calculate possible exposure to electromagnetic

radiation around a BTS antenna. Precise statements are possible either with measurements or

complex calculations considering the complexity of the environment, such as soil conditions,

nearby buildings and other obstacles. The complexity may cause reflection, deflection, and

scattering of electromagnetic fields.

The maximum output power (given in EIRP) of a BTS is usually limited by license conditions

of the network operator.

A rough estimation of the expected exposure in power flux density on a given point can be

made with the following equation:

S = (P(W) x Gnumeric)/(4 x r²(m) x π)

Where,

P = Maximum output power at antenna port of the BTS in W

Gnumeric = Numeric gain (see below)

r = Distance between the antenna and the point of exposure in meters

For the calculation of the Gnumeric,

Gnumeric = 10GdB/10

GdB = Gantenna(dB) – Bcable(dB) – Bvertical-attenutation(dB) – Bhorizontal-attenuation(dB)

B = attenuation in dB
