Millimeter wave technology. Extremely high frequency ehf is the international telecommunication union itu designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz ghz. Millimeter wave technology assume the position the airport security body scanning position that is. Several countries employ the scanners for security. Radio waves in this band have wavelengths from ten to one millimetre so it is also.
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. Millimeter wave technology has had its fair share of doubters in the past few years with questions arising about its suitability over long distances how well it can go through walls and even if. It lies between the super high frequency band and the far infrared band the lower part of which is the terahertz band. Today s millimeter wave technology is mature enough to handle this requirement.
Millimeter waves are electromagnetic radio waves typically defined to lie within the frequency range of 30 300 ghz. Millimeter wave mm wave. Researchers are testing 5g wireless broadband technology on millimeter wave spectrum. Lag times will all but vanish.
Millimeter wave components are usually realized by frequency scaling the microwave components. However an engineer has to deal with several design challenges in terms of higher loss high signal to noise ratio signal distortions etc. One of the most promising potential 5g technologies under consideration is the use of high frequency signals in the millimeter wave frequency band that could allocate more bandwidth to deliver. Counterterrorist detection techniques of explosives 2007.
The millimeter wave region of the electromagnetic spectrum is usually considered to be the range of wavelengths from 10 millimeters 0 4 inches to 1 millimeter 0 04 inches. While implementing a. The microwave band is just below the millimeter wave band and is typically defined to cover the 3 30 ghz range. Millimeter wave technology will allow a 5g network in which all applications even ones that have not been created will get industry leading speed and reliability.
