Measuring Electrosmog Pollution through 5G radiation with measurement technology by Gigahertz-Solutions

Does the 5G frequency spectrum really reach 100 GHz?

The consortium responsible for this has plans up to about 80 GHz so far. However, the uppermost frequency bands are only suitable for transmission in the immediate vicinity, for example from computer to screen. In this respect, this uppermost frequency range is not so relevant for electro-sensitive people, because it is up to you whether you want to use such applications or not (if 5G in this frequency spectrum should be commercially available in a few years).

The planning for 5G in the frequency range around 28 GHz is much more concrete, where the main focus is on (temporary) coverage of, for example, football stadiums, shopping centres and the like, and on wireless Internet on railway lines and in public transport. Here, too, the range is very limited and in order to minimize power consumption, the suppliers will try to concentrate the radiation as closely as possible to the absolutely necessary range. However, the demonstrations so far have revealed major technical difficulties, because even a tree blocking the direct line of sight to the transmitter led to considerable reductions in the transmission rate, even to broken connections.

At which frequencies does 5G transmit?

The frequency bands currently projected are:

  • Around 700 MHz
  • around 2 GHz
  • around 3 to 4 GHz ("Sub 6 GHz Band")
  • around 28/30 GHz
  • up to about 80 GHz

The large gap between 6 GHz and 28 GHz is striking. The only radio services relevant to building biology in this area are the "5 GHz Wi-Fi" (between 5 and 6 GHz) and various radar frequencies between 8.5 and 9.5 GHz.

Are 5G frequencies above 30 GHz particularly harmful?

This is what the experts are arguing about, just as they are arguing about the harmfulness of electrosmog in general. Just think of the decades of discussion about the harmfulness of asbestos! Therefore, a precautionary minimization of personal exposure to 5G radiation seems to make sense. The following, physically unquestionable relation is reassuring: The higher the frequency, the less the radiation propagation, or in other words: The higher the frequency, the higher the attenuation of the 5G radiation (of any HF radiation!) alone through the air or the more through common building materials such as stone, wood or glass. In this respect, interiors, i.e. apartments or houses, already offer quite good protection with regard to the higher 5G frequencies.

Why are the 5G frequencies below 6 GHz particularly critical?

From a building biology point of view, it is particularly important to keep the electrosmog load in sleeping areas low, because the organism should be free of external stress during sleep in order to regenerate.

For technical and commercial reasons, however, it is precisely these lower 5G mobile radio frequencies that will lead to increased exposure to 5G radiation in sleeping areas. This is because lower frequencies have a higher transmission range and better penetration of common building materials for the same energy expenditure. This means for the mobile phone provider: With largely the same infrastructure costs, more customers can be covered, i.e. higher profits can be achieved. The same phenomenon is known from the significantly better area coverage of the lower mobile radio bands compared to the upper ones, for example in mobile radio (900 MHz compared to 1800 MHz for GSM, as well as 800 MHz compared to 1800 MHz compared to 2700 MHz for LTE/4G) or 2.4 GHz Wi-Fi compared to 5 GHz Wi-Fi.

While the 700 MHz are thus particularly recommended for rural areas and smaller towns, the newly auctioned frequency bands around 3 to 4 GHz will be increasingly used, especially in downtown locations, in favor of higher data rates. Even if this requires more transmitting equipment to be set up at closer distances. This is one of the main criticisms of opponents of the 5G expansion.

Why does the market launch of 5G start with the lower frequencies?

Physical laws also apply to 5G, and hardware vendors react to this in a predictable manner: First, there's the greater attenuation of high frequency radiation through the air. From a provider's perspective, "greater attenuation" is synonymous with "more energy input and higher costs" - the commercial consequence: the lowest possible frequency band is always preferred (as is already the case with GSM, LTE and Wi-Fi). The upper 5G bands up to over 50 GHz will therefore remain reserved for very short distances with direct line-of-sight connections in the long term - a positive side effect for the population: their own four walls offer comparatively good protection.

The sarcastic phrase "Money makes the world go round" is of benefit to the general population as an exception and rather incidentally ... a small consolation in view of the even higher total RF exposure with 5G.

Can you measure 5G yourself?

Yes, the physical and commercial laws ensure that the measurement of 5G frequencies (and mobile radio frequencies in general) below 6 GHz will remain most relevant for the general population. In this area, the RF developments of Gigahertz Solutions have established themselves worldwide and for many years now as leaders in building biology as well as among interested laypeople. With the introduction of 5G, we have introduced several new measurement instrument sets that cover the entire "Sub-6-GHz-5G".

Can conventional electrosmog measurement technology measure the 5G modulation correctly?

5G does not place higher demands on measurement technology than 4G (LTE). Actually, higher and higher crest factors would be expected, which are difficult to process in terms of measurement technology. However, chip manufacturers are outdoing themselves in presenting new methods that limit the crest factors to a maximum of 10 dB, because every decibel more drives up the costs of the base stations and thus the costs of the mobile phone providers. Again one of the rare consoling positive side effects of the sarcastic saying "money makes the world go round".

What does Gigahertz Solutions plan for frequencies above 10 GHz?

Currently, no commercial devices are available for the two upper projected 5G bands " around 30 GHz" and " around 70 GHz", let alone RF components in the even rudimentary affordable range. At the same time, these bands are less relevant in building biology practice for the reasons explained above. Of course we will keep an eye on further developments. However, until the situation changes, we will continue to focus on maintaining our existing product range.

Laboratory measurement technology (for tens of thousands of Euros/Dollars) for the higher GHz ranges is of course already available. Renowned manufacturers in this field include Rohde & Schwarz, Anritsu and Narda-STS.
