RF Safety EMF measurement and simulation tools

> RF SafetyEMF measurementand simulation tools

The continuous growth of wireless communication has in the recent past raised public awareness and concern on the potential health hazards due to exposure to “waves” (electromagnetic fi eld). Two non-profi t international bodies have been requested to address this concern: the ICNIRP (International Commission on Non-Ionizing Radiation Protection) and the WHO (World Health Organization).In particular since 1992 WHO has been studying the potential risks associated with so called non-ionizing radiations and in 1998 the ICNIRP has published guidelines that each country should transpose into local laws and regulations. These guidelines are based on the effects that these radiations have on body temperature. Detailed information are available on WHO (www.who.int) and ICNIRP (www.icnirp.org) web sites.

What are reference levels?

To protect people from potential hazards, limits have been fi xed by international organizations. These limits are called Reference Levels and are the maximum allowed E fi eld for a given frequency. These levels are derived from limits on the maximum allowable temperature increase in the body tissues that the fi elds cause. The restrictions refer to the SAR values (Specifi c Absorption Rate) that quantify the rate at which RF (radio frequency) energy is absorbed by the body. SAR values correspond to a temperature increase in a localized area of tissues in the human body. SAR values are complex to measure in real envi-ronment that is why E fi eld reference levels have been set using the following formula:

SAR (W/Kg)=�E(V/m)2/�

Sigma (�) being conductivity of the liquid simulating tissues and rho (�) density of the liquid.

Why do we measure exposure levels?>

Whenever there is electricity (voltage or current) an electromagnetic fi eld (EMF) arises. All types of wireless transmissions (radio/TV broadcasting, voice/data wireless communication) use electromagnetic fi eld. The generated fi eld propagates in waves and is all around us even if we cannot see it or hear it. The electromagnetic fi eld has two components: the Electric (E) Field and Magnetic (H) Field, they are proportional with each other.

and protocols

The basic restrictions and reference levels defi ned by the ICNIRP are guidelines, which have been used as basis by many countries to implement their own recommendations or laws and ensure that these levels are not exceeded. However, some countries or cities have decided to set their own limits indepen-dently from these guidelines.In order to compare the measured exposure levels to the regulatory limits, measurement protocols have been defi ned, such as: ECC/REC/(02)04, EN50383, or IEEE Std.C95.3 for in-situ measurements.

A complete range of radio frequency

safety instruments

SATIMO has developed a range of instruments to measure the level of exposure to the electromagnetic fi eld and to address the following needs:• To monitor actual levels and compare them to the regulatory limits.• To address public concern through appropriate communication.• To provide tools for occupational safety.• To simulate EMF radiation in real environment.

Common sources of electromagnetic fi eld are tele-communication and broadcasting antennas, working on the FM, TV, GSM, UMTS, WiFi… bands and point-to-point or military transmission systems.

5Occupational safety

The EME Guard is a robust device and easily worn on a belt clip, in an outside pocket or in a harness. It is equipped with three independent alarms (vibrator, buzzer and warning light) that alert the wearer as soon as the measured fi eld level exceeds the predetermined exposure threshold.EME Guard comes with software that enables the user to parameterize alarm thresholds to requirement and to save measurement data for monitoring purposes.

A user friendly and fl exible

instrument

The EME Guard Analysis software defi nes two user profi les:

➊ Administrator mode, gives additional rights to confi gure the device to requirements (threshold defi nition).

➋ User mode, enables download and visualization of measurements recorded in the embedded memory of the device.

The Administrator can parameterize the device accor-ding to the thresholds defi ned by his own guidelines. > Only the Administrator is given right of access to device confi guration and parameterization.

STEP 1: Defi ne the reference threshold triggering the visual alarm. The 4 warning lights are activated res-pectively as soon as exposure level attains 25%, 50%, 75% and 100% of the chosen reference threshold.

STEP 2: Defi ne the thresholds triggering the audio and vibrating alarms, be it:Over a 6 minute mean: the alarm is triggered as soon as the mean calculated over the preceding 6 minutes exceeds the predetermined threshold. This 6 minute calculation is the reference duration which conforms to the ICNIRP recommendations. Be it:Instantaneous: as soon as a measurement exceeds the threshold, the alarms are triggered.

STEP 3: Defi ne the recording period.

STEP 4: Start the device (ON/OFF button) and perform measurements.

STEP 5: Import the measurements in the form of secured fi les using a USB cable and display the results.

EME Spy is a light and portable dosimeter which performs on-going measurements of the human exposure level to electromagnetic fi elds on predefi ned frequency bands. It uses patented fi lter technology to identify the contribution of each transmitter (see frequency bands listed next page) and can differentiate uplink (from the phone to the base station- TX) and downlink (from the base station to the phone- RX) for the GSM, DCS and UMTS frequency bands. This solution, unique on the market, enables accurate selective measurements to be made without incurring the costs of an integrated spectrum analyzer.

Thanks to its dedicated software EME Spy Analysis, the dosimeter is easy to program. When the measurement cycle has fi nished, the collected data can be directly transferred to dedicated software with a USB cable. The data can also be exported in Excel, analysed, and compared to the recommended maximum exposure levels (using ICNIRP’s levels as a pre-defi ned reference).

The dosimeter measures exposure

levels autonomously for up

to 20 days

EME Spy Analysis software, enables the dosimeter to be administrated through a USB cable.

STEP 1: Set-up the device.• Defi ne measurement period and duration.• Check the device.• Synchronise the date and time of the dosimeter and the computer.

STEP 2: Start the device (ON button) and perform measurements.

STEP 3: Import measurement data and present results.• Once the dosimeter is connected to the PC, the software can import the measurement data.• Each measurement datum (either the mean for the total fi eld or for each frequency range) is linked to a date and a time.• If the ON button of the EME Spy is pressed at any point in time during the campaign, the measurement will be specifi cally marked in the downloaded fi le.

The collected data can be post

processed and presented

in a clear and simple way

• EME Spy Analysis post-processes the measurement data and presents statistical information in graphical representation. • The software allows the display of both the instantaneous value or the 6 minute mean value.• The data can be exported in Excel and be compiled with other measurement data.

Differentiating up and down link is not only useful to assess the contribution of each transmitter, but also to avoid corruption of the results by a phone emitting close to the dosimeter.

The INSITE Box is an area monitoring device. As opposed to spot measurements (such as measurements made with spectral analysis portable systems), INSITE Box can be positioned in the vicinity of one or several emitting antenna(s) to monitor exposure over a period of time. It includes a GSM/GPRS modem to transfer the data to a FTP site (File Transfer Protocol), allowing direct publication of the data on a dedicated website.

The monitoring station can be operated thanks to INSITE Box Control (installation on site) and INSITE Box Analysis enabling easy management, direct access to the acquired data and results presentation. The measurement cycle follows a 24 hour time frame and is automatically repeated every day. The station will connect itself to the FTP site once every 24 hours to transfer collected data and download new confi guration fi les.

Monitor exposure level

within a geographical area

and web publishing of results

The INSITE Box is connected to a website or a PC through a FTP site. Thus installation requires the user to provide a SIM card for the GSM/GPRS modem.

STEP1: Input FTP details, SIM Card and confi gure cycle parameters. During the installation stage, INSITE Box is connected to a PC (with RS 232), where INSITE Box Control software has been installed.

STEP 2: After the fi rst cycle, use INSITE Box Analy-sis to download the results. The software enables the data to be imported from the FTP site either automa-tically or manually.

STEP 3: If required, use INSITE Box Analysis remote management features to send new confi guration data to the station and modify measurement sequences (for ins-tance if the measurement period needs to be changed).

A tool that gives residents/public

access to information

The data collected on the FTP site can feed a dedi-cated website where measurement information and results are presented. INSITE Box can easily be used to cover more than one specifi c area and be moved from time to time to monitor alternatively other areas. Websites usually display a map, so that residents can easily identify where the stations are, and a calendar where information is presented (with daily, weekly and monthly statistics on exposure levels).

INSITE Free is a compact measurement system for narrow band analysis. The system is composed of a probe connected to a switch/amplifi cation box. The system also requires a spectrum analyzer. These elements can be operated either manually or remotely through INSITE Free software. The SW enables the user to defi ne his measurement scenarios, to analyze measurements, review the results graphically and to generate automatically reports into Excel format. The switch enables successive selections of the three measurement axes to obtain an isotropic result without changing the position of the probe. As it is equipped with an amplifi er, the switch also improves the sensitivity of the system over the 100 KHz to 30 MHz frequency band. Associated with a GPS or with the GPS function of an analyzer and used with ISSBA module, INSITE Free allows the measured levels to be represented on a scanned map or on a Microsoft Map Point format.

Measurement scenarios can be

defi ned by the user to fi t specifi c

requirements

➊ INSITE Free SW is a fl exible tool that can be confi gured by the user to perform measurements and generate reports according to specifi c measurement protocols, in particular those recommended by ECC.➋ In addition, for the French market, INSITE Free/ ANFR SW follows the protocol v2.1 of the French National Agency of Frequencies (ANFR) step by step.

STEP 1: Choose hardware confi guration.In this fi rst phase, the user programs the measure-ment session according to his own hardware confi gu-

ration: spectrum analyzer, GPS, probe, cable, UMTS scanner and switch. For this purpose the probe, cable and switch calibration fi les are selected and loaded.INSITE Free works with all the most frequently used spectrum analyzers.*

STEP 2: Defi ne measurement scenarioOnce the hardware has been confi gured, the user can program the measurement scenarios:• Choose frequency bands to be measured from a list or create user-defi ned bands.• Defi ne the channels or specifi c carriers.• Defi ne channel width.• Choose attenuation mode.• Choose analysis mode (peaks, TDMA or UMTS).• Choose automatic or manual defi nition of RBW/VBW.

STEP 3: Perform measurement analysis.The data collected for each band is presented on the main window of the software. Measurements corres-ponding to each of the three axes can be displayed in order to check the polarisation of the electric fi eld.

Depending on the characteristics of the spectrum analyzer, the user can repeat the following analysis modes:• CW Analysis: selection of peaks according to predefi ned threshold.• TDMA analysis: extrapolation of the level that corresponds to BCCH.• W-CDMA analysis: UMTS decoding (measurement and extrapolation of the CPICH value).The user can re-launch measurements using specifi c detection modes (positive peak, negative peak, sam-ple…) and measurement modes (Max. hold, Min. hold, and average) available with the spectrum analyzer.

STEP 4: Visualize results.The results can be visualized with the following functions:• Full scan or per frequency band.• Zoom in with peak identifi cation threshold.• 3 types of scale for a better high and low band visualization.• Quick view of element’s properties.

Sessions are saved in XML and results can be expor-ted into Excel.The results can be compared to the reference levels given by specifi c guidelines. Two guidelines are availa-ble by default:• ICNIRP• Safety Code 6(Other reference levels can be added upon request).

Perform isotropic measurements without changing the position

of the probe

INSITE Free System performs a measurement for each axis and over all predefi ned bands. The value measured on each axis is then converted into fi eld value.

For each Band

One scan for each axis X Y Z

Conversion in fi eld value [E] (dB V/m) = Pmes (dBm) – 13 + |loss| + AF (dB m-1)

AF : Antenna Factor loss: cable loss, switch loss

Isotropic value calculation [ETOT] (V/m) = ( [Ex]2 (V/m) + [Ey]2 (V/m) + [Ez]2 (V/m) )1/2

EMF Visual>

> Type of tool: • Electromagnetic exposure simulation software

> User profi le: • Broadcast, PMR and mobile phone operators and installers, municipalities, governmental agencies, regulatory and certifi cation bodies

> Function: • EMF Visual is a prediction, analysis and communication tool, which can accurately simulate exposure within a few hundred meters of the antennas whilst taking into account its environment

> Available modules: • BSA Synthesis, cote2emf and EMF2ascii

STEP 1: 3D Scenario construction.The EMF Visual software permits the creation of 3D scenes by importing 3D objects (*.wrl or *.dxf) from the EMF Visual generic database or using the Cote2emf module. This module allows the creation of a 3D scenario from a 2D map or by importing GIS fi les.

Cote2emf module: build & export 3D scenes from 2D map images or GIS fi les. • Defi nition of building and ground fl oor outlines with graphic tools.• Special GIS fi le format for automatic defi nition of the outlines (*.shp fi les from 3 types: Type 5: « polygon » Type 3: « polyline » Type 15: « polygonZ »).• Defi nition of element types: buildings, houses, trees, roads, pavements.• Random generation of buildings for large area.


• Complete range of graphical tools to adjust the 3D object properties.

• Grouping of objects: create, move, copy and paste objects in group; translate or rotate a group.

• Wide choice of 3D objects to represent grounds, buildings, houses, masts, towers, indoor objects.

• Tools for assignment of the electromagnetic properties to materials.

Import of VRML/Open Inventor or DXF 3D objects


• Advanced texture mapping of faces from a bitmap image.

STEP 2: Antenna selection and installation.The EMF Visual software permits the use of antenna models from the EMF Visual generic database or a cus-tom antenna using BSA Synthesis module.

A library of antenna models.• A complete database of generic models of the most current antennas in GSM, DCS and UMTS networks.• A KATHREIN database for GSM, DCS and UMTS networks.• An additional database of FM and Wifi antennas• Possible integration of an ambient electromagnetic fi eld at a specifi ed frequency.

Antenna parameterization tools.• Geometric visualization of the antenna main beam cone in the scene together with graphic tools for adjusting position, tilt, azimuth and power.

BSA Synthesis Module: defi ne antenna characteristics and create customized antennas.

• BSA Synthesis computes magnitude and phase for each unit cell to generate an antenna model that fi ts with far fi eld radiation pattern: - vertical and horizontal -3dB beam width and frequency. - fi rst upper side lobe suppression. - number of cell units or antenna length. - front to back ratio.• Analysis of antenna model from unit cells magnitude and phase data (1D and 2D array antenna).• Polar and Cartesian display of the radiation pattern.• Exportation of the antenna model to the EMF Visual database.


STEP 3: Computation.After defi ning the computation volume around the area of interest, the electromagnetic fi eld level calculation is launched. The calculation is based on optical geometry (ray tracing). It allows simulation to be performed over a wide area in terms of wavelength and the interactions with the environment of the radiating sources to be ta-ken into account.

• Accurate representations of the near fi eld by considering the contribution of each sub-cell of the antenna.

• Defi nition of a computation volume around the area of interest.

• Selection of the active antenna.• Adjustment of the mesh step (number of computation points).• Non uniform grid to improve resolution around the antennas and to speed-up the calculations.

STEP 4: Result display.Once the computation is fi nished, the user can use iso-surface tool or cut plane to display the level of expo-sure in the vicinity of the 3D environment.

Iso-surface

Vertical cut plane

Horizontal cut plane


• Selection of the active antennas and adjustment of the input power of antennas to analyse co-sitting interactions.

• Multiple cut plane and multiple distance measuring possibilities for security perimeter defi nition.• Evaluates the levels of exposure in terms of E-fi eld (V/m), H-fi eld (A/m), Power Density (W/m²), % of the E-fi eld or % of the Power for multi-frequency sources.• Determines the safety distances with respect to standards or recommendations (EU recommendation, ICNIRP, and so on …).• Visual post-processing of the results: choice of colour or transparency.

STEP 5: Result exportation (optional).

EMF2ascii module allows the conversion of the binary result fi les into an ASCII Txt fi le (permits result to be loaded in Excel, Matlab …).• Creates ASCII fi le that contains the E fi eld value (V/m) computed with EMF Visual.• Displays the E fi eld values for each antenna with the corresponding Cartesian coordinates.
