At GCI, the safety of our customers is our highest priority. That’s why we comply with all applicable local, state and federal regulations and rely on research and best practices when introducing new technology including 5G. There is no evidence that exposure below the guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) carries any known health risks. Below is some additional information to address concerns about the safety of 5G.
For more information about the studies of 5G and safety, visit www.gci.com/mobile/5g/responsibility which includes links to more information and research from the WHO and other trusted organizations. If you have any questions or concerns, please call GCI Customer Service at 1-800-800-4800.
In all wireless networks, connected devices communicate using radio frequency electromagnetic fields (EMF), also known as radio waves. People have very good questions about the safety of these networks, and GCI is committed to respond with all available information. Expert groups and public health authorities, including the World Health Organization, have reviewed all EMF studies and concluded that the evidence does not demonstrate any health effects associated with radio wave exposure from radio base stations and equipment as long as companies comply with international limits. And we guarantee that we do comply. Your safety—and the safety of our employees—is of the highest importance.
Since 1996, our contracted project partner, Ericsson, has co-sponsored over 100 independent studies on electromagnetic fields and health, primarily through the Mobile & Wireless Forum (MWF). To ensure scientific independence, firewalls were in place between the industrial sponsors and the researchers. All results were made available by publication in open scientific literature.
The electromagnetic frequencies used for 5G are part of the radio frequency spectrum that has been extensively researched in terms of health impacts. Over 50 years of scientific research has already been conducted into the possible health effects of the radio signals used for mobile phones, base stations, and other wireless services including frequencies planned for 5G.
The data from this research has been analyzed by hundreds of expert review groups throughout the world. Weighing the scientific methodologies, repeat results and the whole body of science, there is no evidence to convince experts—and GCI—that the guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) carry any known health risks, for adults or children.
The EMF-Portal is an open-access extensive database of scientific research into the effects of EMF, including studies on the effects of RF on health. It is managed by the RWTH Aachen University, Germany and linked from the WHO website. EMF-Portal contains more than 25,000 published scientific articles on the biological and health effects of EMF and 2,500 studies on mobile communications.

Yes – the current research is focused on the alignment of the human exposure guidelines at frequencies below and above 6 GHz where the measurement parameter changes from Specific Absorption Rate (SAR) below 6 GHz to Power Density above 6 GHz. For more on SAR see http://www.sartick.com/.
The research is also focused on the dielectric properties of human skin to ensure that the power density levels and averaging area across the skin align with the temperature values that are the basis of the human exposure guidelines.
For example, a mobile device operating at 5 GHz will be assessed for compliance by measuring the SAR. The SAR levels are set to limit the absorbed power so that the temperature rise in the head or body from the device operating at maximum power is below the equivalent relevant limit. If the same device was operating at 6.5 GHz, a power density measurement would be required, so the measurement parameters would need to ensure the same limit in temperature rise is maintained.
Base stations used for 5G will consist of various types of facilities including small cells, towers, masts and dedicated in-building and home systems.
Small cells will be a major feature of 5G networks particularly at the new mmWave frequencies where the connection range is very short. To provide a continuous connection, small cells will be distributed in clusters depending on where users require connection and this will complement the macro network 5G base stations.
5G networks will work in conjunction with 4G networks. In many cases, existing 4G base stations will be used for additional 5G equipment.
The technical standards for the 5G networks and devices are still under development however it is expected that the size of the compliance zone for 5G antennas will be similar to that of other mobile technologies using similar transmitter powers.
Mobile network antennas are typically directional. Compliance zones extend in front of the antenna and a small distance above and below.
Mobile networks are designed to use only the power needed to provide quality services. Too much power would cause interference and affect all users. One of the goals of 5G is a substantial increase in network energy efficiency.
Where 5G is added to an existing site with other mobile technologies, the existing compliance zone may increase due to the addition of the 5G technology however this will depend on the site design and network configuration.
No – Active Denial Systems developed by the military use very high powered mmWave directional signal, sometimes called a ‘heat ray’ in the 90 GHz band designed to heat the surface of targets such as the skin of a human, and through the heat, control or restrict access.
5G and other mmWave radio communications use different frequencies and a fraction of the power. The human exposure limits for mobile communications technology prevent heating occurring.
