3.6 Safety distance requirements (complianceboundaries)

This section describes compliance with reference levels (based on basicrestrictions) for general public and occupational exposure to radio frequencyelectromagnetic fields

Installing base stations to ensure public safety

This equipment generates radio frequency energy, which has a thermal effectwhen absorbed by the human body. For this reason compliance boundariesspecific to this equipment have been established. The thermal effects of radiofrequency energy can exceed safety levels when a person is inside the established




compliance boundaries. Observe the compliance boundary, and make sure thegeneral public has no access to areas inside the established boundaries. Theinformation shown in Warnings and cautions provided section below is takenfrom the relevant section of Nokias user manual containing warnings andcautions specific to the equipment.

Installing base stations to ensure installer safety

Installation engineers need to be aware of the potential risk of the thermal effectsof radio frequency energy and how to protect him/herself against undue risk. Theinformation shown in Warnings and cautions provided section is taken from therelevant section of Nokias user manual containing warnings and cautionsspecific to the equipment.

Warnings and cautions provided

Reference safety distances

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

Warning

Do not go any closer to a live antenna than the compliance boundary. Theradio frequency energy generated by the antenna poses a serious health risk.

Warning

If performing installation or maintenance procedures on a BTS, make surethat all transmitters in the area are switched off.

When assessing the applicable boundaries, the European standards EN 50383,EN 50384, EN 50385 and Council Recommendation 1999/519/EC foroccupational and general public electromagnetic exposure limits - see Annex A -have been applied.

The statements shown below are taken from the Nokias user manual containingwarning and cautions specific to the equipment.



Assessment applying SAR measurements

European standards EN 50383, EN 50384 and EN 50385 do not includespecifications for whole body SAR measurements. Whole body SARmeasurements are not required for transmitters that have maximum output powerlevels too low to result in exposure levels that can reach the whole body SARcompliance limits under any conditions. Whole body SAR exclusion powerlevels have been based on the worst case assumptions. For details, see the tablebelow.

Table 6. Whole body SAR exclusion power levels

Exposure category Maximum output power (rms)

General public Max power [W] = general public wholebody SAR limit [W/kg] * 12.5 kg: 4-year-old child body mass = 1 W

Occupational Max power [W] = occupational wholebody SAR limit [W/kg] * 42 kg: 16-year-old worker body mass = 16.8 W

Localised SAR measurements can only be used when:

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

2. The surface area of the energy generating element is less than 60 cm (23.6in.) 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 Nokia FlexiWCDMA Base Station.

Assessment of compliance boundary

The compliance boundary is defined as the area around the antenna shown in theArea around the antenna figure below. The antenna is located at the origo.Distances from the antenna are shown. The top and side views are shown in theAntenna side and top view figure below, in Picture 1 and Picture 2.

When using different configurations

IMPORTANT:

. In tables 'Dimensions of compliance boundary in meters for generalpublic (GP)' and 'Dimensions of compliance boundary in meters(Occupational)' the compliance boundaries are given for differentpower levels, including the typical and worst case levels. If an exposurelimit, antenna, and/or configuration is used which does not correspondto the levels given in tables 'Dimensions of compliance boundary inmeters for general public (GP)' and 'Dimensions of complianceboundary in meters (Occupational)', the compliance boundary mustbe 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 Blater in this section. This model is applicable for calculating thecompliance boundary for the far-field region and over estimates thecompliance boundary for the radiating near-field region, but is notapplicable for calculating the compliance boundary for the reactivenear-field region where the distance from the antenna is less than orequal to / 4.

ANNEX B: Far-field calculation method

This model is applicable for calculating the compliance boundary for the far-fieldregion and over estimates the compliance boundary for the radiating near-fieldregion, but is not applicable for calculating the compliance boundary for thereactive near-field region where the distance from the antenna is less than orequal to /4, which is 3.75 cm at 2000 MHz. Therefore, all calculations are validwhen the compliance boundary is greater or equal to the antenna dimensions plus /4.

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

Figure 5. Formula for safety distances

The 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/m)

Note

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 thecompliance boundary, the far-field data, antenna size and reactive field criteriahave to be taken into account.

3.7 Compliance with EMC, RF and safety

In Europe this means compliance with Directive 1999/5/EC of the EuropeanParliament and of the Council of 9 March 1999 on radio equipment andtelecommunications terminal equipment and the mutual recognition of theirconformity.

In other market areas additional compliance is fulfilled according to relevantauthority requirements.

5 Power requirements5.1 Grounding requirements

Grounding is required to ensure personnel safety and to avoid electrostaticdischarge which can damage the equipment.

To protect the BTS from damaging overvoltages through antenna equipment,communication cables, or power supply lines, grounding cabling must be plannedand installed before the installation of the base station. To avoid interference, it isrecommended that large grounding systems are designed case-specifically.

A power plug with a protective ground connection is not sufficient for NokiaFlexi WCDMA BTS. Grounding must have a fixed, non-removable connection.

Note

Follow local requirements for earthing (grounding). The principles andrequirements vary in different countries.

Observe the following recommendations when planning the BTS grounding:

. The grounding cable is connected with screws to the BTS grounding point.

. The minimum cross-section of the copper (Cu) grounding conductor isfollowing:. Grounding cable cross-section has to be more than any of AC or DC

power feeding cable cross-section.. When 220-240 VAC is used, power cables shall be 1.5 - 2.5 mm2

(15...13 AWG) and grounding cable 2.5 mm2 (13 AWG).. When 100-110 VAC is used, power cables shall be 1.5 - 2.5 mm2

(15...13 AWG) and grounding cable 4 mm2 (11 AWG).. When 48 VDC is used, power cables shall be 6 - 10 mm2 (9...7

AWG) and grounding cable 6 mm2 (9 AWG).



Power requirements

. The earthing (grounding) resistance target of the BTS site is =10 . If it isnot possible to reach this target due to difficult conditions, for instance inareas such as solid rocks or dry desert, the earthing (grounding) resistancecan be max. 150 .

. The ground cable must be connected to a main grounding busbar.

. Route the ground cables as directly as possible from the equipment to thegrounding point. Avoid unnecessary loops and sharp bending of thegrounding cable. The ground cables should not be run parallel with powercables.

. The external antenna feeders must also be grounded according to the locallegislation if the antennas are exposed to lightning.

5.2 Mains power requirements

Warning

Danger of lethal voltages! Make sure that the mains power breaker is off,and that the cabinet is properly earthed (grounded), before removing anyconnections from the cabinet.

Ensure that the site has a main switch for disconnecting the site power. Thedisconnecting device shall disconnect both input supply poles simultaneously.

The cross-sectional area of the Main Earthing Conductor (PE) shall not be lessthan live and neutral conductors nor less than 6 mm2. The impedance of the earthconnection shall be as low as possible.

7 3rd party cabinet requirementsBasic requirements for a 3rd party cabinet

The basic requirements for a 3rd party cabinet are the following:

. 19-inch rack with site trays

. Minimum depth 600 mm (23.6 in.)

. Rear air intake

. Front exhaust

. Proper cable routing

. DC power to the BTS

. The operating temperature in the cabinet must be -33...+55C (-27F...+131F)

Requirements for Flexi BTS module level cooling in a 3rd party cabinet

A Flexi BTS module shall be installed in the cabinet without the rear side andfront side plastic covers. The air volume flow requirement for one Flexi BTSmodule is 140 m3/h. The pressure drop caused by the rear side wall and front door(wall) for one module fan can at the maximum be 25 Pa (including the combinedpressure drop for both walls) with an air volume flow of 140 m3/h. Flexi BTSmodules cooling fans minimum distance to any obstacle in the rear side of thecabinet is 40 mm (1.6 in.). The BTS power consumption must be taken intoconsideration when planning site cooling.



3rd party cabinet requirements

Figure 16. Module level cooling in a 3rd party cabinet

The entire cabinet volume flow is dependent on the number of modules used (forexample, if three modules are used, the entire cabinet volume flow is 420 m3/h(3*140 m3/h) and the pressure drop caused by the front and rear door maximum25 Pa). All modules must receive cool ambient air, and the circulation from thefront of the module to the rear side of the module must be prevented. There mustbe a long enough distance to the wall (or any other obstacle) in the rear side of thecabinet, so that the required airflow rate (140 m3/h) is reached in all modulesused.

It is recommended that the module cables be routed so that they do not preventthe air outflow from the BTS.
