Millimeter Wave Technology Safety

Electromagnetic radiation safety august 7 2017.

Millimeter wave technology safety. Frequency spectrum used in 5g technology can be divided into three major bands such as sub 6 ghz range mid range and high range millimeter waves. Millimeter wave scanners produce a special type of microwaves with wavelengths that fall in a range exactly between 0 001 meters 1 millimeter and 0 01 meters 10 millimeters. Millimeter wave scanners produce their waves with a series of small disc like transmitters stacked on one another like vertebrae in a spine. A single machine contains two of these stacks each surrounded by a curved protective shell known as a radome connected by a bar that pivots around a central point each transmitter emits a pulse of energy which travels as a wave to a person standing in.

As more and more systems come on line and are used in everyday applications the possibility of inadvertent exposure of personnel to mmws increases. Military designed for area denial perimeter security and crowd control. Several countries employ the scanners for security. Harnessing millimeter wave spectrum for faster data speeds is one of the biggest breakthroughs of 5g the next generation cellular networking technology following 4g lte but there are concerns.

A millimeter wave scanner is a whole body imaging device used for detecting objects concealed underneath a person s clothing using a form of electromagnetic radiation typical uses for this technology include detection of items for commercial loss prevention smuggling and screening at government buildings and airport security checkpoints. Currently technology is being developed that makes use of the millimeter wave mmw range 30 300 ghz of the radio frequency region of the electromagnetic spectrum. Informally the weapon is also called the heat ray since it works by heating the surface of targets such as the skin of targeted human beings. Millimeter wave health effects.

In other words the waves emitted by mmw scanners are much larger and therefore have less impact on small structures such as human proteins and nucleic acids. Frequency range above 24 ghz and below 100 ghz for 5g applications. The active denial system ads is a non lethal directed energy weapon developed by the u s. The emergence of 5g fifth generation telecommunications networks has been in the news lately because the wireless industry has been pushing controversial legislation at the state level to expedite the deployment of.

Frequency range below 6 ghz range is grouped under sub 6 ghz category.
