require-An air filter must be used together with the BTS cabinet when standard based tional environmental conditions presented in Environmental specifications and require-ments for a stand-alone BTS are exceeded Typically, a cabinet with an optional air filter

opera-is needed:

• in places where dust is a concern,

• next to a dusty road with heavy traffic,

• in sandy terrain with the possibility of wind-blown sand in the air,

• next to an industrial plant with significant emissions of dust or other particles, such

as cement factory, sawmill, and so on,

• nearby a cornfield with heavy straw dust during harvesting,

• in places where salt fog or acid rain caused by air pollution is a concern,

• in site locations where surrounding metal structures show signs of corrosion due to extreme conditions (salt in air),

• in locations with especially heavy rainfall and high humidity combined with air tion

• near sea shore:

• with dense salt fog due to breaking waves,

• with dense salt fog and line of sight to the sea (not behind a large building),

• where wind-driven salt fog from sea can be identified

See the below map for a generic model for sea salt distribution Typically, the further away from the sea the BTS is located the less salt is accumulated However, due to local environmental variables a general rule for determining the distance cannot be stated Always check the local environmental conditions before installing a BTS in the proximity

of the sea

3.8 Safety distance requirements (compliance boundaries)

This section describes compliance with reference levels (based on basic restrictions) for general public and occupational exposure to radio frequency electromagnetic fields

Ensuring public safety

This equipment generates radio frequency energy, which has a thermal effect when absorbed by the human body For this reason compliance boundaries specific to this equipment have been established The thermal effects of radio frequency energy can exceed safety levels when a person is inside the established compliance boundaries Observe the compliance boundary, and make sure the general public has no access to

areas inside the established boundaries The information shown in the Warnings and

cautions provided section below is taken from the relevant section of Nokia Siemens

Networks product documentation containing warnings and cautions specific to the equipment

Installing base stations to ensure installer safety

Installation engineers need to be aware of the potential risk of the thermal effects of radio frequency energy and how to protect themselves against undue risk The informa-

tion shown in the Warnings and cautions provided section is taken from the relevant

Warnings and cautions provided Reference safety distances

When working close to transmitter antennas, the proper safety distances must be observed The minimum safe distance from an antenna is measured in metres

When assessing the applicable boundaries, the European standards EN 50383, EN

50384, EN 50385 and Council Recommendation 1999/519/EC for occupational and

general public electromagnetic exposure limits - see Annex A - have been applied.

The statements shown below are taken from the Nokia Siemens Networks product umentation containing warning and cautions specific to the equipment

doc-Assessment applying Specific Absorption Rate (SAR) measurements

European standards EN 50383, EN 50384 and EN 50385 do not include specifications for whole body SAR measurements Whole body SAR measurements are not required for transmitters that have maximum output power levels too low to result in exposure levels that can reach the whole body SAR compliance limits under any conditions

Trang 27

mainte-tions For details, see the table below.

Localised SAR measurements can only be used when:

1 The separation between the phantom and the outer surface of the energy generating element is 40 cm (15.6 in.) or less

2 The surface area of the energy generating element is less than 60 cm (23.6 in.) by

30 cm (11.8 in.)

3 The frequency is in the range of 800 to 3000 MHz

For the reasons above, SAR measurements are not applicable to Flexi Multiradio Base

Station.

Assessment of compliance boundary

The compliance boundary is defined as the area around the antenna shown in the

fol-lowing Area around the antenna figure The antenna is located at the origo Distances from the antenna are shown The top and side views are shown in the following Antenna

The component specifications for 900 MHz and 1800 MHz also apply to 850 MHz and

1900 MHz products, respectively, and can be used to demonstrate compliance with FCC guidelines for human exposure to radio frequency electromagnetic fields contained

The worst-case power level configuration is when the power at antenna input is 60 W with 2100 MHz frequency variant and 40 W with others.

When using different configurations IMPORTANT:

• In tables 'Dimensions of compliance boundary in meters for general public

(GP)' and 'Dimensions of compliance boundary in meters (Occupational)' the compliance boundaries are given for worst case power levels If an exposure limit, antenna, and/or configuration is used which does not correspond to the levels given in tables 'Dimensions of compliance boundary in meters for general public (GP)' and 'Dimensions of compliance boundary in meters (Occupational)', the compliance boundary must be re-calculated according to EN50383.

• The formula for calculating the compliance boundary using the far-field

model, which is referenced in EN50383, is given in ANNEX B later in this section This model is applicable for calculating the compliance boundary for the far-field region and over estimates the compliance boundary for the radiating near-field region, but is not applicable for calculating the compliance boundary for the reactive near-field region where the distance from the antenna is less than or equal to λ / 4.

public electromagnetic exposure limits

Note that all SAR values are to be averaged over any period of 6 minutes Localised SAR averaging mass is any 10 g of contiguous tissue: the maximum SAR so obtained should be the value used for the estimation of exposure

Basic restrictions between 10 GHz and 300 GHz are given in power densities For pational exposure, it is 50 Wm-2 and for general public exposure 10 Wm-2

ANNEX B: Far-field calculation method

This model is applicable for calculating the compliance boundary for the far-field region and over estimates the compliance boundary for the radiating near-field region, but is not applicable for calculating the compliance boundary for the reactive near-field region where the distance from the antenna is less than or equal to λ /4, which is 3.75 cm at

2000 MHz Therefore, all calculations are valid when the compliance boundary is greater or equal to the antenna dimensions plus λ /4

The minimum safety distance (compliance boundary) in metres, or 'rmin', is calculated according to the following equation:

Figure 6 Formula for safety distancesThe meaning of each formula component is as follows:

• N is the number of transmitter units per one antenna

• G is the antenna gain (in dB)

• L is the minimum cable losses (in dB)

• Pout is the maximum power of one transmitter unit (in W)

• S is the maximum power density limit (in W/m²)Note that in the far-field, the field calculation does not take into account the antenna size, which is assumed to be a point source Therefore, when calculating the compliance boundary, the far-field data, antenna size and reactive field criteria have to be taken into account

In Europe, this means compliance with Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity.

In other market areas additional compliance is fulfilled according to relevant authority requirements

If the distance is > 200 m, the standard multi-mode optical transceivers (SFP), which are delivered with the RF Module, must be replaced with single-mode optical transceivers (for example, Single Mode Optical Transceiver FOSA).

To preserve the IP55 protection (where modules are located outdoors), install the Nokia Siemens Networks manufactured short length single-mode optical cable with IP55 seal

at the Flexi modules (for example, Single Mode Optical Cable (LC-SC) 2 m or 5 m) and connect it to your optical cable

DC cable lengths of the Feederless Site Concept

The DC cable length varies depending on the type of the cable used The following tables show the characteristics of the different cases

These values are valid with the following conditions:

• The System Module provides a power supply (48V) to the RF Module in normal operation

• The type of the used cables is: MCMK/MCCMK (max operational temperature +70°C (+158°F))

• The distances above are valid for the DC cable temperature range -33°C - +70°C 27.4°F - +158°F)

voltage of the RF Module must be 36V at the DC input connector with full operating power.

General issues to be considered when installing the DC cables of the feederless site:

• In case of a power break, the BTS functions with batteries The output voltage of the batteries starts to decrease in time

• The batteries should be installed in the proximity of the System Module to minimize additional voltage drop before the RF Module

• If the cables are under a protective cover, the temperature of the cables can increase This increases the resistance of the cables and the voltage drop is greater between the System Module and RF Module

• The power dissipation of the DC cable adds to the power consumption of the site Examples:

• Power dissipation with a Dual RF Module (with max load of 2x40W) of the 100m

DC cable is ~50 W when 16 mm2 is used and ~130 W when 6 mm2 is used

• Power dissipation with a 3-sector RF module (with max load of 3x60W) of the 100m DC cable is ~100 W when 25 mm2 is used and ~160 W when 16mm2 is used

These values are valid with the following conditions:

• The input of the BTS DC voltage is 40.5V

• The type of the used cables is: MCMK/MCCMK (max operational temperature +70°C (+158°F))

• The distances above are valid for the cable temperature range -33°C - +70°C 27.4°F - +158°F)

(-The other DC cable lengths and sizes can be used In all cases the minimum input voltage of the RF Module must be 36V at the DC input connector with full operating power

DC cabling principles and shielding

The Nokia Siemens Networks recommended DC feeder cable type is MCCMK or MCMK shielded cable An equivalent locally supplied DC cable may be used Nokia Siemens Networks Flexi outdoor 2 m DC cable must be used to provide necessary IP55 protec-tion at both ends of the connection to Flexi RF or System Module

DC cable extension:

• There is an additional Nokia IP55 2m DC cable in the FSEC sales package By cutting both cables in one end and using IP55 protection to both the RF and System Module they can be used for extending the DC cable distance

• A long DC cable needs to be shielded and grounded

• Connection of the long DC cable and Nokia Siemens Networks IP55 cable is mended to be done in an IP55 outdoor weather protected space, e.g in Flexi External OVP box (FSEC)

• The FSEC clamping range is from 19 to 28 mm DC cable diameters

☞ If the diameter of the cable is smaller than 19 mm (0.75 in), use either self-fusing tape or heat-shrinkable tube to increase the cable diameter to 20-21 mm (0.79-0.83 in) to fulfil the IP67 requirement The distance between the expansion and the stripped part of the cable must be at least 10 cm (4 in)

g In feederless and distributed site installations, Ohm's law cannot be applied alone because inductance must also be taken into account

The Single RF Module may be supplied directly from a 100/240V AC supply by installing the Flexi Power AC/DC sub-module (FPAB) in the free place of the unused filter The requirements for the FPAB are described in table Flexi Power AC/DC sub-module for Single RF Module (FPAB)
