Alot of confusion has arisen about which frequencies are currently being used to support 5G and other networks in the UK. Anything from 700MHz to 90GHz has been alleged, with many people alarmed that the frequencies used are also deployed in Directed Energy Weapons. Let's explore that.
I looked at several websites where information is given on frequencies used by the existing UK companies, and collated the following information.
Frequencies Currently Used by Major UK Networks
EE O2 Vodafone Three
800MHz (4G) 800MHz (4G) 800MHz (4G) 800MHz (4G)
1800MHz (2G & 4G) 900MHz (2G & 3G) 900MHz (2G & 3G) 1800MHz (4G)
2100MHz (3G) 1800MHz (2G) 1800MHz (2G) 2100MHz (3G)
2600MHz (4G) 2100MHz (3G) 2100MHz (3G) 3.4GHz (5G)
3.4GHz (5G) 3.4GHz (5G) 2600MHz (4G) 3.6-4GHz (5G)
3.6GHz (5G) 3.6GHz (5G) 3.4GHz (5G) 700MHz (5G)
700MHz (5G) 700MHz (5G) 3.6GHz (5G)
As you can see 5G isn't yet using the mmWave frequencies some believe. See spectrum graph below:
Higher frequencies are being discussed; Ofcom is engaged in freeing up the 8GHz and 26GHz spectrums. A lower frequency is also on the table: 1492-1517MHz, which is due to be available in December 2022.
If they can get away with it Ofcom then want to open up 32GHz, 37-43.5GHz, and 66-71GHz to mobile companies. But tech boffins maintain that "higher frequencies aren’t universally better."
As far as health and safety testing is concerned we read in a January 2022 research paper that a search for studies published revealed there are "no human experimental studies by 5G nor at the RF EMF frequencies higher than 2500 MHz"
However studies do exist; a Cambridge study discusses therapeutic effects at mmWave frequencies. Researchers found that directing 61GHz at a power density of about 13mW/cm2 at humans caused "hypoalgesic effects", particularly when "exposed at the acupuncture points."
Hypoalgesia is a decreased sensitivity to pain, a chemical free alternative for suffers of chronic pain. That is a better future, to untangle the spectrum and work only within those fields that pose no threat. But this technology, unregulated, uninsured, rolled out wild-west style, and used without regard to real-time risk assessment is potentially devastating to humanity. What if it fell into the wrong hands? Immunity from prosecution guaranteed by legislation? Hardly an indication that it hasn’t.
The Cambridge Study found ocular lesions forming in the eyes after intense exposure to 60GHz, but at lower levels "no discernable effects."
Meanwhile the MOD has sunk £billions (of tax payer's money) into research and development of Directed Energy Weapons (DEWs) which use frequencies from as low as 16KHz to as high as 100GHz. That covers the whole wifi/radio frequency spectrum and then some. So that's ok then. Nothing to worry about there.
What about wifi frequencies? These are not part of the mobile network but the other network of home wifi routers and hotspots. Wifi companies have started using 5GHz (confusingly calling it “5G” internet) and some are now offering up to 6GHz, which they call Wifi 6 and Wifi 6E; those frequencies range between 5.93 and 6.43 GHz.
According to a feverishly excited Digital Wireless Magazine: domestic wifi users "will not only be able to use the 2.4GHz and 5GHz but now 6GHz as well."
I recently spoke to a woman whose neighbour installed wifi 6, and since then she has been experiencing very strange symptoms while at home. She describes it as a relentless "pulsing sensation in my body." Synergistic effects have not been studied, i.e. what happens when several frequency signals intersect making a "hot spot". Previously the idea of electrosensitivity was unknown to her and she would have scoffed at "tinfoil hat" theories. Now she and her child are both struggling to sleep and asking for help.
Much higher frequencies are used in Point to Point (PtP) wifi systems. These use private relay towers and are purely directional, from point A to point B, not the 360° spread which a RF tower emits. That’s ok until a biological organism (think bird) intercepts the beam.
PtP uses antennae that can use "almost any frequency." These frequencies "include, but are not limited to 2.4GHz, 5GHz, 24GHz, 60GHz, 80GHz."
The PtP buying guide goes on to tell us, "if you have a link over 1km or so that is crucial to your business, then 60GHz and microwave technology will be best suited for your needs."
You can get indoor versions of PtP, called smart repeaters, used in larger buildings and indoor spaces. "Cost-effective,” quips a Businesswire press release, “single-box dual-band mmWave smart repeaters with integrated phased array antennas manufactured by WNC and powered by Movandi BeamXR dual-band 28GHz and 39GHz ... for private networks and other indoor applications including office buildings, schools, campuses, convention centers and sports arenas."
I hope that cleared up the understandable confusion over signal frequencies used by both mobile telephony and wifi. The two wireless systems are deployed across our long-suffering planet in a sickening array of crisscrossing frequencies, that are in dire need of careful scrutiny.
