Measuring Electrosmog Pollution through 5G radiation with measurement technology by Gigahertz-Solutions
Does the 5G spectrum really go up to 100 GHz?
The consortium responsible for this has plans up to around 80 GHz so far. However, the highest frequency bands are only suitable for transmission in direct proximity, for example from computer to screen. In this respect, this highest frequency range is not so relevant for electrosensitive people, because it is up to them whether they want to use such applications or not (if 5G is then commercially available in this frequency spectrum in a few years).
Planning for 5G in the frequency range around 28 GHz is much more concrete, where it is mainly a matter of (temporary) coverage of, for example, soccer stadiums, shopping centers and the like, and wireless Internet on rail lines and in public transport. Here, too, the range is very limited and, in order to minimize power consumption, providers will try to concentrate the radiation as narrowly 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 has led to considerable reductions in the transmission rate and even to disconnections.
What frequencies does 5G transmit at?
5G used multiple frequency bands:
- around 700 MHz
- around 2 GHz
- between 3 and 4 GHz (also worldwide in any case below 6 GHz, „Sub 6 GHz Band“)
- around 28/30 GHz
- to about 80 GHz (in planning für the very close proximity)
Aufällig is the große gap between 4 GHz and 28 GHz. At building biologically relevant radio services can be found in this range only the „5 GHz WLAN“ (between 5 and 6 GHz) and vielfältige radar frequencies between 8.5 and 9.5 GHz.
Are 5G frequencies üabove 30 GHz particularly harmful?
This is what the experts are arguing about, as well as üabout the topic of the harmfulness of electrosmog as a whole. One thinks only of the decades-long discussion around the Schädlichkeit of asbestos! A precautionary minimization of personal exposure to 5G radiation seems to make sense. Reassuring is the following, physically undoubted connection: The higher the frequency, the lower the radiation propagation or expressed differently: The higher the frequency, the higher the attenuation of the 5G radiation (any RF radiation!) by the air alone or the even more by common building materials such as stone, wood or glass. In this respect, indoor spaces, i.e. apartments or houses, already offer quite good protection against the higher 5G frequencies.
Why are the 5G frequencies below 6 GHz particularly relevant?
From a building biology point of view, it is especially important to keep electrosmog exposure in sleeping areas low, because the organism should be free of äeren stresses 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 longer transmission range and better penetration of common building materials for the same amount of energy. For the mobile network provider, this means: 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 communications countries compared to the upper ones, for example in mobile communications (900 MHz versus 1800 MHz for GSM, as well as 800 MHz versus 1800 MHz versus 2700 MHz for LTE) or 2.4 GHz WLAN versus 5 GHz WLAN.
While the 700 MHz are thus particularly recommended for rural areas and smaller towns, the newly auctioned frequency bands between 3 and 4 GHz will be used increasingly in inner-city locations in favor of higher data rates. Even if this means that more transmitters will have to be installed at closer intervals. After all, this is precisely one of the main points of criticism from opponents of 5G expansion.
Why is the rollout of 5G starting with the lower frequencies?
Physical laws also apply to 5G, and hardware vendors are responding predictably: First, there is the greater attenuation of high-frequency radiation through the air. From the provider's point of view, „greater damping“ is synonymous with „more energy consumption and higher costs“ – the commercial consequence: the lowest possible frequency band is always preferred (as was already the case with GSM, LTE and WLAN). The upper 5G Bänder up über 50 GHz remain thus in the long term very short distances with direct line of sight – positive side effect für the population: The own four Wände offer comparatively good protection.
The sarcastic saying „money rules the world“ is thus here for once and rather incidentally benefiting the general population … a small consolation in view of the with 5G again increased overall RF exposure.
Can you measure 5G yourself?
Yes. The physical and commercial laws ensure that the measurement of 5G frequencies (and cellular frequencies in general) below 6 GHz will remain most relevant to the general population. In this area, Gigahertz Solutions' RF developments have established themselves worldwide and for many years as leading in the field of building biology and among interested laymen. With the introduction of 5G, we have introduced several new instrument sets, for example, the HF38B-W (sophisticated technology for private users) and for professional building biologists the HFEW59BD plus, established as a standard in building biology worldwide. Both sets fully cover the entire "sub-6 GHz" spectrum of 5G, with the latter even going well beyond it.
5G potentiates the problem:
The radiation of a 5G antenna is bundled onto the respective cell phones in use. So if you are in the vicinity of a 5G cell phone in use or somewhere between it and the 5G antenna - even unintentionally, if necessary - the exposure multiplies abruptly. This is why it is important to repeat the measurement of 5G regularly.
What are Gigahertz Solutions' plans for frequencies above 10 GHz?
Currently, for the top two projected 5G bands „ around 30 GHz“ and „ around 70 GHz“ no commercial end devices are available, let alone RF devices in the even remotely affordable range. At the same time, these devices are less relevant in building biology practice for the reasons explained above. Of course, we will keep an eye on further developments. Until the situation changes, however, we will continue to focus on the maintenance of our existing product range.
Laboratory measurement technology (for thousands of euros) for the higher GHz ranges is of course already available. Renowned manufacturers in this field are, for example, Rohde & Schwarz, Anritsu and Narda-STS.
