(I assume he’s a “principal” technologist — though it’s always good to be principled ;-))
I could likely attend the Council meeting.
My name is Thomas Anderson and I reside at 485 Fairview St in Ashland, OR. I am currently a Principle Technologist with ATIS (
https://www.atis.org/) – a non-for-profit North American Standards organization that writes standards for the telecommunications industry. ATIS provides the technical standards for 5G (as well as 4G and 3G) as well as other standards that (for example) provide a framework to limit robo calls.
As a technical standards expert on 5G, I can assure that the 5G is the safest mobile standard technology to date. I have taught an OLLI course on the technical aspects of 5G and would be glad to share this information with the council.
As a summary, it is important to understand that:
- 5G is an optimization of 4G using the same over-the-air coding scheme (OFDMA) but is roughly 15-30% more efficient than LTE/4G (other things being equal). As such, 5G radiates less than 4G for a given amount of data transmitted and therefore ... IF YOU REALLY WERE CONCERNED ABOUT EMF ... you would advocate for 5G deployment.
- In addition, in the OLLI class I show (mathematically) that once you are 25 feet or so from a cell tower antenna (at the top of the tower), the amount of radiation you might get from that cell tower IS LESS THAN the maximum radiation from a cell phone itself. And since these towers are typically 50 - 150 feet high and there are no human habitable structures typically within 25 of feet of the antennas on the tower - clearly the tower is never the problem (FCC has power emission rules to make sure this is true). So ... IF YOU REALLY WERE CONCERNED ABOUT EMF ... you would not really care about cell towers.
- We also learned in the 5G class that cell phones only transmit at a minimum level required to make sure the cell tower can "hear" the cell phone. This minimizes interference and maximizes battery life – both critical concerns enabling higher / faster data speeds. This technology was first introduced in 3G so is nothing new. Power levels of cell phones are then typically 100s-1000s of times less than the allowed maximum (the advertised SAR levels for phones are based on the worst case transmit power of the phone). As such, if you have a strong signal path (say 4-5 bars) the phone is transmitting at 100's – 1000's times LESS than the SAR value). Minimum cell phone power occurs when you are "close" (say 5 bars on your phone) to a tower. IF YOU REALLY WERE CONCERNED ABOUT EMF ... you would then want more cell towers and/or many small cells in the community so that you could get 5 bars on your phone everywhere and thus the cell phone would be transmitting at very low levels of EMF compared to the legal maximum.
- Additionally, the FCC notes that there are "no established negative health effects from radio waves emitted from mobile phones and base stations complying with international limits". If you look closely at the research that EMF advocates point to regarding EMF harm … the actual research does not support the claim of EMF harm. This is of course reflected in the FCC statement above.
I understand that there is some discussion in Ashland relative to a proposed 5G cell tower. I would like to emphasize that the deployment of any cell tower will lower EMF levels for cell phone users and as such, if EMF is of concern, it would be prudent to encourage more deployment of cell towers.
I am happy to discuss the science, technology and mathematics (already outlined in the OLLI material) as needed.
