5G, Trees and Line of Sight

Digital Survivor contributor L O’Connor explains the concept of Line of Sight and why 5G means trees disappearing from our view.

As many of Glasgow’s trees are being hacked, chopped and pruned back to the point of no return, I wanted to be able to establish the links between our trees and the rollout of 5G.

From researching the locations of mobile phone masts from transmitter to receiver, I learned about the Line of Sight.

This is simply being able to see point A to point B or one mast to another. Telecommunications companies call this an “optical wireless connection”.

Some Lines of Sight can be 25 miles long; hard to imagine but not when you picture a bunch of antennas on the roof of a multi-storey block of flats and a 25 metre mast on top of a large hill.

In between this Line of Sight is the “Fresnel Zone” (more terminology from the telecommunications industry).

A Fresnel Zone is not a straight line. In fact its shape is similar to a fat cigar or thin oval shape.

This zone needs to be at least 60% free of any obstructions, including trees with growth penetrating into it.

Through www.mastdata.com I was able to establish a couple of Fresnel Zones in the west of Glasgow and immediately noticed the unfortunate trees within this zone.

Digital Survivor cares about trees being felled in order to make way for environmentally unfriendly 5G.

These trees have been left well alone for decades and I know this because I live not far from them.

It’s documented and generally accepted that 5G is rather poor at traveling any great distance, due to being easily blocked, so the Fresnel Zone for 5G will be even greater in size [but see “addendum” below]. This is a huge concern for anything or anyone within it as much higher and more concentrated levels of electromagnetic fields have been recorded within these zones.

In Glasgow there are many regeneration projects where new trees are being planted in city and urban areas. But one notices how they tend to be of the smaller deciduous variety growing no more that 10 to 12 feet.

In other parts of the UK companies like FLI Structures are “planting” life-like trees that are really masts; they even have one that resembles a “dead tree stump” – how ironic.

In a sad way, our poor trees are alerting us to these danger zones. And as the rollout of 5G intensifies many more will suffer.

We need to make people aware of this and take a leaf (no pun intended) from the people of Sheffield who fought hard to spread the word over recent years.

Protest and protect our beloved trees!

Millimeter waves will travel to infinity, just as light does, as long as they are not blocked by something – such as trees, walls of buildings and even rain.

Commentators elsewhere have claimed that the real reason for planting this line about MMWs travelling only short distances is so that phased array antennas can be installed outside every second house or so because the real purpose is mapping our homes and controlling our movements.

5G is battlefield technology.
