1. OVERVIEW

This ICNIRP (International Commission on Non-ionizing Radiation Protection) certification of base station

installations in the Vodacom SA network is subcontracted to EMSS Consulting.

The ICNIRP guidelines specify two levels for safe exposure, namely the Public and the Occupational

levels. The (higher) Occupational levels are applicable to RF trained personnel for the duration of their

workday, while the Public levels are applicable to the general public.

EMSS has expertise in the field of human exposure assessment to radio-frequency fields. Work performed

includes site surveys, numerical predictions (computer simulations) and the interpretation and

establishment of guidelines for limiting exposure. EMSS has more than a decade experience in the

assessment of human exposure to cellphone technologies. These include measurements and numerical

predictions of exposure to cellphones and base-station antennas. EMSS publishes its research results in

international, peer-reviewed literature and has written numerous technical reports on base-station site

surveys performed on request from cellular operators.

EMSS has developed the software package, IXUS, to assist with the documentation and management of

ICNIRP compliance certification of the large number of sites in a typical cellular network. A customized

version of IXUS (VodIxus) is used for the ICNIRP certification project for the Vodacom network.

This document describes the three different groups of sites in section 2 and the different compliancecategories for each site group in the sections 4, 5 and 6.

2.2 Masts

The Masts group of sites are sites with

- PowerLevel set as High

- InstallationType in the list below

o Lattice mast

o Sectional pole

o Camouflaged tree

o Telecom Tower

The assessment of compliance with the ICNIRP guidelines for Mast sites is typically much simpler than for

building sites. These sites generally have good access control in place, preventing public access to the

exclusion zones around the antennas. The compliance classification of mast sites is outlined in section 5.

2.3 Low Powers

The Low Power site group consists of all sites with the PowerLevel field set as Low. The InstallationType is

irrelevant for this site grouping.

Low PowerLevel sites are sites where typically less power is available at each antenna than at a High

Powerlevel site. The following sites are classified as Low Power sites:

- Sites with internal antennas only

- Mini sites

- Micro sites

- Distributed antenna systems (DAS) sites. Note that for DAS installations, the assumption is made

that the power is distributed evenly to all the antennas.

3. COMPLIANCE MEASUREMENTS

Compliance measurements are also used as a tool in the ICNIRP compliance certification of sites. Some of

the cases where measurements are a useful tool are listed below:

Generic rules and worst case simulations are mostly used for ICNIRP compliance assessment of

sites. When these assumptions yield a Non-compliant result and it is believed that the

assumptions are over-conservative, a measurement survey can be used to determine the

presence of exclusion zones on site, if any, and then certify the site accordingly. The procedure

used for these Compliance measurements are given in Section 3.1.

Some sites have high power transmitters, such as TV/radio services, co-located with the Vodacom

antennas. Due to the typical complexity of such a site, an accurate exclusion zone simulation is

unfeasible. Therefore measurements are used for compliance assessment at such sites. In these

cases measurements are used to check if other services: 1) result in significant increase of

exposure levels around Vodacom antennas; 2) result in Occupational Exclusion zones in areas

that Vodacom workers need to access. The procedure used at these High Power Transmitter sites

are given below in Section 3.2.

When technical information on some co-located transmitters is not available, or these systems are

not supported by VodIxus, compliance measurements can be used in the compliance certification

of these sites. Again, in these cases measurements are used to check if other services: 1) result

in significant increase of exposure levels around Vodacom antennas; 2) result in Occupational

Exclusion zones in areas that Vodacom workers need to access. The procedure used for these

sites with unknown radiators are also given in Section 3.2 below.

3.1 Measurement Procedure at sites for Compliance purposes

To determine the presence of exclusion zones on a BTS site, measurements are performed with both the

NARDA SRM-3000 selective radiation meter and the NARDA NBM-550 broadband meter. The ED5091

three axis E-field probe used for the total exposure measurements with the latter meter measures the total

exposure in the frequency range from 300 kHz to 50 GHz, but cannot discriminate between exposures

from different sources or frequencies. These measurements are not only used to identify the maximum

exposure in the pre-identified areas on site, but also in determining any contributions to the exposure at

each measurement position from frequencies outside the frequency range of the SRM-3000.

The SRM-3000 selective radiation meter is used with the 3AX 75M-3G Three-Axis E-Field Probe. The

latter has been designed and manufactured specifically for exposure evaluation close to base station


8/53

CONFIDENTIAL


facilities with a frequency range from 75 MHz to 3 GHz. The SRM-3000 is used to perform a broadband

measurement at the position of maximum exposure as determined with the NBM-550, along with spectrum

measurements for the GSM900, GSM1800 and UMTS frequency bands. A safety evaluation

measurement is also performed and, depending whether the Total exposure is more than 1 % of the

ICNIRP general public guidelines, an extrapolated worst case exposure including the contribution from all

the cellular operators on site is determined through post-processing of the spectral data.

This measurement procedure is based on internationally established procedures for radio-frequency

exposure assessment together with policies and procedures for ICNIRP [1] compliance assessment of

base station sites and according to protocols specified by CENELEC, [3].

3.2 Measurement Procedure at sites containing high power and/or unknown radiators

For sites where high power transmitters feed radiators, or where unknown radiators are present close to

Vodacom equipment, measurements are performed with the NARDA NBM-550 broadband meter. The

SRM-3000 meter are however used to only scan for presence of activity in its entire frequency band,

mainly to determine whether the known or unknown radiators are transmitting at the time of the

measurement survey. A broadband and safety evaluation measurement are usually the only

measurements that gets logged for this. This activity scan is performed on the ground level around co-

located masts, or in a generally central area on rooftops.

The NBM-550 is then used to determine the exposure as a percentage of the ICNIRP occupational

guideline at all areas on site around Vodacoms equipment, as well as around other equipment on access

paths to and from Vodacoms equipment that will be used by Vodacom personnel and sub-contractors.

The measurement procedure followed is based on internationally established procedures for radio-

frequency exposure assessment together with policies and procedures for ICNIRP compliance assessment

of base station sites and according to protocols specified by CENELEC, [3]

On access paths on masts (usually on the ladder of the mast structure, but also scanning each platform enroute), measurements are performed at the level of all antennas en route to the Vodacom equipment,

including the level of the Vodacom antennas and 2 (two) meter above the highest Vodacom antenna (or on

a platform in close proximity above the equipment). On building rooftops measurements are taken at the

most common access routes to/between the Vodacom equipment. All other areas on the access paths

(e.g. travelling in the shaft escalator and floor landings of a telecommunications tower, or between different

sets of antennas on the ladder of a mast) are scanned by means of a NARDA Radman RF monitor worn

on the body of the surveyor. If no alarm signals are activated on this monitor during the survey, the range


9/53

CONFIDENTIAL


in which the highest percentage of exposure were logged can be seen displayed on the monitor post

survey.

At each identified measurement position a complete scan of the immediate environment is f irst performed

before the reported measurement is taken at the position where the maximum measurement value was

found during the scan. The tip of the probe is kept away at least 0.5 meter from any conducting surfaces,

walls and the body of the surveyor. The Radman can be used to scan in areas as close as 0.2 meter from

structures.

No areas on masts or on rooftop sites where Vodacom personnel do not need access are surveyed.

An uncertainty assessment for the in-situ measurements performed with the NARDA NBM-550 broadband

meter has been performed by EMSS, for a confidence interval of 95%. An RF hazard drawing, visually

summarizing the exclusion zones for occupational workers on site, include this uncertainty assessment in

the results and are drawn for every site containing high power and/or unknown radiators.

4. COMPLIANCE CLASSIFICATION OF BUILDING SITES

The Buildings site group is used for sites where the cellular antennas are installed on buildings. This

includes sites where antennas are installed on rooftops (typically on poles/masts), wall mounted antennas,

silos and water towers. Additional details on this group are given in section 2.1.

Building sites are classified into Compliant, Provisionally Compliant or Non-Compliant. The criteria for

these different compliance statuses are given in Sections 4.1 to 4.3 below, while the approval checklist for

building sites is given in Appendix A.

Section 3 gives details of compliance measurements which are used in the certification of some sites.

4.1 Compliant

A building site is classified as compliant when:

There are no Public or Occupational Exclusion Zones in areas where the general public might

have access.

OR

Signage (including painted lines) and access control are present on the site to the extent that

exposure above the Public or Occupational guidelines is unlikely because it can reasonably be

expected that members of the public would pay sufficient attention to the control measures.


10/53

CONFIDENTIAL


AND

The Occupational Exclusion Zones at the site are clearly marked (through signage or painted

lines) for the benefit of RF workers

OR

The antenna installations are such that Occupational Exclusion Zones are not easily accessible

and RF workers would, through RF training, have gained the knowledge on how these zones

should be avoided.

In line with the above mentioned definitions sites may be classified as compliant when, for example, only

warning stickers are still required on the top and bottom of inaccessible wall mounted and roof mounted

antennas where there is a very small chance of the public entering into the Exclusion Zones of the

antennas and RF workers would know not to work right in front of the antennas.

For mast structures (not poles) on top of buildings the following criteria are used: Where Access control,

under control of cellular operators or Telkom, is in place around the mast structure, use mast site

certification criteria. Site installation type roof is still set to roof and a numerical model is required. If such

access control is not present on site, assess like any other building site 1.

4.2 Provisionally Compliant

When a building site has Public Exclusions Zones in areas where the public might have access, but it isnt

likely or there are sufficient access restrictions to prevent regular public access, a site is classified as

provisionally compliant. This also includes sites where barriers and signage must still be installed outside

the Public Exclusion Zones, but there are no obvious reasons why the public or any general maintenance

worker needs to gain access to these areas.

Typically a provisionally compliant building site would later be classified as compliant, after installation of

additional signage or access control.

4.3 Non-Compliant

A building site is classified as Non-Compliant when there are Public and/or Occupational Exclusion Zones

to which the public has regular free access. If there is any obvious reason for the public to gain access to

or pass through one of these exclusion zones and there arent adequate access restrictions and/or signage

the site has to be marked as non-compliant. A site will also be classified as non-compliant if general

1See site Malvern, BS number 2953, as an example.


11/53

CONFIDENTIAL


maintenance work has to be done in these exclusion zones and appropriate signage and/or access control

is not in place.

Sites in this category must be escalated to the Non-compliant list immediately.


12/53

CONFIDENTIAL


5. COMPLIANCE CLASSIFICATION OF MAST SITES

Based on the inaccessibility of exclusion zones and the access control and RF warning signage installed

on the site, a mast site is classified as Compliant, Public Compliant, Provisionally Compliant or Non-

Compliant. Appendix B gives further details on the abovementioned criteria while details of the compliance

classifications are given in sections 5.1 to 5.4 below. The certification checklist for mast sites is given in

Appendix C.


5.1 Compliant

A mast site can be classified as compliant if ALL of the criteria below are met

o The ICNIRP General Public exclusion zones are not easily accessible, as detailed in Appendix B.1

o Sufficient access control is present at the site, as described in Appendix B.2.

o Adequate RF signage is present at the site access points, as detailed in Appendix B.3.

o A Vodacom Caution sign (HAZ30) or a MTN Radio Worker Warning Sign is present at themost likely access route to the antennas, before entering the Public exclusion zone on routeto the Occupational exclusion zones. The same physical sign on site can be used for thiscriteria and the Adequate RF signage criterion.

5.2 Public Compliant

A mast site can be classified as Public Compliant if ALL of the criteria below are met

o The ICNIRP General Public exclusion zones are not easily accessible, as detailed in Appendix B.1.


o Adequate RF signage is present at the site access points, as detailed in Appendix B.3.


13/53

CONFIDENTIAL



A mast site can be classified as Provisional compliant if ALL of the criteria below are met

o The ICNIRP General Public exclusion zones are not easily accessible, as detailed in Appendix B.1.


This classification is used for sites where the Adequate RF Signage criterion, detailed in Appendix B.3, is

not met.

This classification is also used for sites where both the BS number AND site name are not indicated on the

site OR where both the BS number AND site name indicated on the site are incorrect. These sites are only

classified as Provisionally complaint since occupational workers need to confirm access to the correct site

for NMC power down and other actions.

Standard sentences for the Compliance Certificate comments used in these cases, are given in

Appendix F.3.2.

5.4 Non-Compliant

Sites which cannot be classified as at least provisionally compliant are classified as Non-Compliant.



14/53

CONFIDENTIAL


6. COMPLIANCE CLASSIFICATION OF LOW POWER SITES

Compliance of Low Power sites is based on information obtained from Vodacom and information obtainedthrough site visits by EMSS personnel. The factors considered for the assessment are:

o Public accessibility of the Generic Public exclusion zones (including when someone might beperforming general maintenance in the vicinity of the antennas),

o Sufficient access control is in place for all access routes to the antennas on site (typically notrequired), and

o Adequate RF signage installed at the antennas on site (typically not required).

Conservative generic exclusion zones were calculated for typical antennas and these zones are used in

the assessment of Low Power sites2. Note that for DAS installations, it is assumed that the power is

distributed evenly to all the antennas.

Based on the criteria above, Low Power sites are classified as Compliant, Provisionally Compliant, or

Non-Compliant. More details on these classifications are given below in sections 6.1 to 6.3, while the

compliance assessment procedure for Low Power sites is given in Appendix D.


6.1 Compliant

A Low Power antenna is classified as compliant if no lights, smoke detectors, security cameras or other

antennas (or other systems that could require maintenance) are located inside the Public Exclusion Zone

(and no part of a persons body is likely to remain inside the exclusion zone for a continuous 6 minute

period of time while performing required maintenance) AND the Public exclusion zone is not entered when

walking around in the immediate public areas surrounding the antenna.


If there are lights, smoke detectors, security cameras or other antennas (or other systems that could

require maintenance) located INSIDE the Public Exclusion Zone but outside the Occupational exclusion

zone (and no part of a persons body is likely to remain inside the exclusion zone for a continuous 6 minute

period of time while performing required maintenance) AND the Public exclusion zone is not entered when

walking around in the immediate public areas surrounding the antenna, a Low Power antenna is classified

Provisionally Compliant. Standard compliance Certificate text is given in Appendix F.4.1.

2See Appendix E: ANTENNA TYPES & FIELD EXCLUSION ZONE FIGURES


15/53

CONFIDENTIAL


At Low Power sites where one or more of the antennas are hidden (behind behind ceilings or wall panels,

or casted within concrete slabs or walls), the antenna is classified as Provisionally Compliant and standard

compliance Certificate text for this case is given in Appendix F.4.1.

6.3 Non-Compliant

If there are lights, smoke detectors, security cameras or other antennas (or other systems that could

require maintenance) located INSIDE the Occupational Exclusion Zone (or a certain part of a persons

body is likely to remain inside the exclusion zone for a continuous 6 minute period of time while performing

required maintenance) AND/OR the Public exclusion zone IS entered when walking around in the

immediate public areas surrounding the antenna, repeat the assessment with SAR exclusion zone figures.

If the antenna is still Non-Compliant, classify the antenna as NON-Compliant.

APPENDIX B. DEFINITIONS FOR MAST SITE CERTIFICATION

The common criteria used in the compliance classification of a mast site are detailed below. The

certification checklist for mast sites is given in Appendix C.

B.1 INACCESSIBILITY OF EXCLUSION ZONES

For a site to be classified as Compliant, Public Compliant or Provisionally Compliant the ICNIRP general

public exclusion zones must not be easily accessible, as detailed below. The ICNIRP general public

guidelines must be adhered to in all locations where the public has access, also taking other structures

(e.g. buildings, other masts, terrain slope) in close proximity to the mast into account. Compliance to this

criterion can be investigated using the (quick) generic exclusion zones detailed below or through a detailed

VodIxus 3D analysis of the exclusion zones at the specific site.

Also note the exclusion of structures not deemed easily accessible, at the end of section B.1.

Generic exclusion zones

The public exclusion zone for panel antennas is conservatively given as a cylinder with a specified radius.

Three scenarios are catered for, as detailed in Table 1 below. The parameters given in this table are

indicated in Figure 1, with Hb including a 2m distance below the bottom of the public exclusion zone. This

generic exclusion zone was calculated using the worst case single antenna conditions for equipment

currently used in the Vodacom network [2], and extrapolating these results for shared sites.

zone was calculated using the worst case single antenna conditions for equipment currently used in the

Vodacom network [2], and extrapolating these results for shared sites.

Detailed Ixus exclusion zones

In cases where the conservative, generic exclusion zone detailed above is accessible by the public, a more

detailed numerical analysis of the exclusion zones at the specific site is required. Antenna parameters as

well as geometrical details of the site are required for such an analysis with VodIxus. An example of such

an analysis is shown in Figure 2 below.

Figure 2. Detailed assessment of a mast site.

Exclusion

Structures such as electricity pylons, light poles and floodlights which dont have ladders or platforms and

for which access equipment (such as a cherry picker) are required, are allowed into the general public

exclusion zones depicted in Figure 1, but not into the occupational exclusion zone depicted in Figure

3. These structures are not deemed easily accessible to the general public. Similarly, telecommunication

masts with access control are allowed into the general public exclusion zone, but not into the

occupational exclusion zone depicted in Figure 3.

The occupational exclusion zone for panel (or omni) antennas is conservatively given as a cylinder with

radius 136m, starting 2m below the lowest cellular antenna and extending to 2m above the highest cellular

antenna. This generic exclusion zone was calculated using the worst case single antenna conditions for

equipment currently used in the Vodacom network [2] and extrapolated for shared sites.

B.2 ADEQUATE ACCESS CONTROL

The following criterion is used when assessing the access control to the site. The site must have access

control, under the control of a cellular operator (Vodacom/MTN/CellC) or Telkom, Sentech or Eskom. Both

locked gates or guarded entrances are accepted. This access control can be at the perimeter of the site

(e.g. on gate in fence surrounding the site) or at the access to the mast structure (e.g. door at the bottom of

the sectional pole)

If an extra ladder (or other means) is required to access the antennas, this can also be deemed as

sufficient access control. See for example Figure 4 and Figure 5 below.

A site can be deemed to have sufficient access control, if there seems to be sufficient access control

present on site, but a photograph of the lock on a gate is not available. In these cases, certify the site as if

the lock is present and add a pending action for the site that EMSS must photograph the lock.

B.3 ADEQUATE RF SIGNAGE

A RF sign must be present at an access control point, for the criterion of adequate RF Signage to be

satisfied. This RF Sign can be a Vodacom Notice sign (HAZ29), a Vodacom Caution sign (HAZ30), an

MTN accepted sign, a CellC site information board, a Telkom Notice, Caution or RF guideline sign or any

of the other RF signs shown in Figure 6 below.
