THE SIGNIFICANCE OF 5G HIGH FREQUENCY EMISSIONS

You have probably heard that the intention of the telcos it to buy bandwidth up to 1 Terahertz in order to make sure everyone gets their digital 5G signals. This may have no significance to the majority of the population. “Just another waveband”; one might say with a shrug.  But the behaviour of telcos is all carefully calculated to make more money. They are not doing this for the good of your health or for your download speed;  but for the benefit of their bank balances. They expect to make trillions out of it. It is carefully calculated. They have set it up so they can’t be blamed for illness and death.

Any wavelength or frequency has specific effects on molecules. Microwaves boil water. That’s not good news for the water in our bodies. 60GHz breaks up the oxygen molecule so that it is useless for breathing.  I have heard a rumour that 60GHz is a frequency they have tried for 5G in Wuhan. In fact the oxygen in the atmosphere attenuates the signal severely and reduces its coverage. A section of the EME spectrum transmission is blocked by water, as we know from the effect of fog on vision. This latter is a problem for telcos too as they want us to be exposed 24/7, rain or shine. They know that the frequency band which can best pierce the rain and fog is up to 300GHz and then over 30 THz into the FIR band.

On the diagram above, the vertical coordinate is the dB/km scale of attenuation or signal loss. It shows where oxygen interferes with the signal and vice cerca at 60GHz.
Over 300GHz fog and rain become opaque to the signal. Eg. Rain can weaken a signal by 10 dB/km. That is a loss of 9/10 of the original. But into the Far Infra Red (FIR) range, the rain cloud becomes transparent, so the signal will get through. This problem limits the expansion into the millimetre wave territory.

For the time being 5G in NZ is using frequencies in the 3.4 – 3.8 GHz band as well as old TV bands on the 700 MHz range. Several networks say that they will eventually switch to 28 GHz.
