Meet Jeff. He is a contractor that repairs air conditioners, waterproofing, elevators and other equipment on building roofs. He is also a rigger and able to climb towers to install and maintain antennas. Jeff is one of the new features in IXUS 3.5. He is a person annotation and he was added in IXUS to give users a better understanding of the scale of their installations. The purpose of compliance simulations is to establish whether there is an accessible exclusion zone and Jeff is the perfect annotation to demonstrate this right there in the 3D view. If Jeff is able to access an exclusion zone, there is a good chance that access to that area needs to be controlled and signs need to be put up on the access route to warn Jeff that the RF levels might exceed the standards.
Jeff – Annotation
Jeff also requires compliance documentation on site and a good idea is to provide Jeff with a copy of the compliance assessment document. IXUS Manager quickly generates these documents in a few clicks through the report wizard. We have made a number of improvements in version 3.5 in the report wizard including a step to add photos that were uploaded in the IXUS Manager. We have also added a few more content controls to make more information from the database available to be used in reports.
We have been very busy in keeping up with advances in antenna designs and EMF compliance techniques and are very proud to announce the release of IXUS 3.4. Proper support for various antenna types, full 3D rendering of compliance zones and one click document generation makes IXUS the most advanced EMF compliance tool available. Here are a few of the things you will notice in this release.
We reworked our internal representation of antenna models to support multi-port antennas as well as multi frequency band configurations on our custom antennas models. IXUS 3.4 also supports much higher power levels on antennas, accommodating levels typically used for radio and television broadcasting. These changes led to the optimisation and refinement of the IXUS calculator, now updated to Version 12.2.
We’ve added a point to point method to create environmental slices, similar to the way the polygon and building shapes are created. This makes adding an environmental slice on oddly shaped objects and roofs much easier. We have also made big improvements to the interaction speed of the IXUS Modeller with regards to rendering of environmental slices. The detail levels are adjusted dynamically which makes it possible to add multiple environmental slices without slowing the application down.
We’ve extracted the safety standards into an isolated level. This allows users to update or add new safety standards without having to update the IXUS Modeller software. Users can perform calculations at the proposed (in some cases more conservative) levels even before they are published, future proofing simulations and reducing the number of re-assessments required.
Supported standards still include the ICNIRP limits endorsed by the World Health Organisation, ‘FCC (OET65)’ standards used in the USA, ‘BRV B11’ used in Germany, and the Industry Canada (IC) ‘Safety code 6’ standards. This update allows us to be much more flexible in the build-up and roll out of proposed changes.
Have a look below at the change log and keep an eye out for the update.
In keeping up with the fast pace of technology IXUS now supports all the latest LTE wireless communication standards at the various frequency bands in use. A highly requested feature was added to allow users to calculate an exclusion zone at a user specified level of the selected standard. This allows assessors to simulate an exclusion zone at variable levels for example at 25% of the specified standard.
We also improved the integration between IXUS and the Online Antenna Portal making it easy to get the antennas that are not available on your database.
After marketing and investing internationally we have successfully entered the North American markets by supporting the compliance standards published by the FCC and Industry Canada Safety Code 6. We will continue to update and improve the IXUS calculator and we hope that this is the start of many new good relationships.
It has been a busy year for the IXUS team and we are very proud to announce the launch of IXUS 3.0. The product has evolved over time into a more complete, comprehensive EMF compliance solution that we are all very proud of. It’s been simplified into pluggable modules giving users the option to select only the functionality required, be it EMF simulation, RF measurement, or just data management and reporting.
It’s been extended to contain various internationally accepted EMF standards like ‘FCC (OET65)’ used in the USA, ‘BRV B11’ used in Germany, and the Canadian ‘Safety code 6’. An uncertainty model in line with IEC 62232 was developed making it possible to adjust the confidence interval for the simulation results. IXUS 3.0 has a new fresh look and feel that we hope breathes a bit of new life into the repetitive nature of the job. Improvements in reporting allows both custom template reports to be added and existing report templates to be edited using Microsoft Word, making reports fully customisable.
Various standards are being used globally for evaluating compliance for human exposure to radio-frequency electromagnetic fields. In the United States, the Federal Communications Commission (FCC) has adopted and used recognised safety guidelines since 1985. The FCC guidelines were derived from recommendations of the National Council on Radiation Protection and Measurements (NCRP) and the Institute of Electrical and Electronics Engineers (IEEE). The exposure limits used by the FCC are expressed in terms of electric and magnetic field strength and power density for transmitters operating at frequencies from 300kHz to 100GHz.
The actual values used in IXUS software when selecting the FCC standard have been published by the FCC and can be found in either of two informational bulletins on the FCC Web site at OET Bulletin 56 or OET Bulletin 65.
These FCC guidelines were set up in consultation with, and from research supported by various federal health and safety agencies such as the US Environmental Protection Agency (EPA) US Food and Drug Administration (FDA), Occupational Safety and Health Administration (OSHA) and National Institute for Occupational Safety and Health (NIOSH). Countries in Europe, Africa and Asia have adopted exposure guidelines developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The ICNIRP safety limits are generally similar to those of the NCRP and IEEE, with a few exceptions.
The NCRP, IEEE and ICNIRP exposure guidelines identify similar threshold levels at which harmful biological effects may occur. The level of exposure recommended by ICNIRP is somewhat different in the lower and upper frequency ranges and for localised exposure. In addition, the NCRP, IEEE and ICNIRP guidelines for maximum permissible exposure are different for different transmitting frequencies.
The World Health Organisation (WHO) EMF Project is working towards providing a framework for harmonisation of these different international of RF safety standards. IXUS Software now allows the user to select the required exposure levels from a selection of different internationally accepted standards.
IXUS now has a built-in, user customisable uncertainty model. The newly published IEC 62232 Standard requires an uncertainty model for the ray tracing assessment method used in IXUS Modeller software.
Users can choose to include or exclude feed system loss and scattering and reflection uncertainties in the model and have the option to run simulations at the following confidence intervals:
Upper two-sided 95%
Upper two-sided 80%
Lower two-sided 80%
Lower two-sided 95%
An upper 2-sided 95% confidence interval means that there is a 97.5% certainty that the simulated fields are conservative over the actual fields. This will typically be used by operators who want to ensure that the calculations they do with IXUS and the resulting control boundaries around antennas are conservative. A lower 2-sided 95% confidence interval means that there is a 97.5% certainty that the simulated fields are lower than the actual fields. This might be used by regulators who investigate RF compliance at sites and who want to be confident about non-compliance findings. ‘Best estimate’ refers to the statistically most likely value. This is where the simulated value is most likely to equal the actual field value.
In the past performing a compliance assessment that included uncertainty estimations was a laborious process. This feature simplifies the process and reduces the effort required. See the attached example for more information on base station compliance assessments and uncertainty.
Full uncertainty analyses were performed for the ray tracing assessment method, as required by the IEC 62232 standard. A 95% Confidence Interval (CI) is used in the results and related control boundaries presented, ensuring conservative results for 97.5% of all cases.
IXUS was recently represented at the 33rd annual meeting of the Bioelectromagnetics Society in Halifax, Canada where we presented the innovative techniques used for optimisation of ray-tracing algorithms for EMF safety assessments of base stations.
We would like to thank all those who attended the meeting, for many fruitful discussions on IXUS Software and EMF safety in general. We look forward to meeting again, if not sooner then at the next BEMS meeting. View the abstract or have a look at our presentation if you want to know more.
This video shows the basic functionality of the IXUS Measurement Module. Base stations are assigned to specific surveyors and measured using the Narda SRM 3006. The Narda SRM measures GPS coordinates and records a voice message with each measurement. Afterwards it is connected to a PC and measurements are associated and uploaded to the IXUS Manager server. On the IXUS Manager you can download a .GPX file that opens in Google Earth. Create aerial pictures and upload them in the Manager along with photos of the base station. Automatically generate a report using all the base station information, measurements, aerial pictures and photos.
