How do radio frequency radiation and electromagnetic fields affect human beings?
All living organisms are sensitive to radio frequency radiation (RFR) and electromagnetic fields (EMFs). Life depends on this sensitivity at the correct intensity. For example, radiation from the sun helps humans make vitamin D, but too much causes cancer. Scientific evidence shows that some people can sense changes in atmospheric electricity like thunderstorms, while 3.6% are sensitive to man-made RFR/EMFs. To protect these people and others from man-made RFR/EMFs, governments must adopt guidelines that include non-thermal effects.

What are Radio Waves and Microwaves?
#industrialsafety #industrialsafetycourse
Radio waves and microwaves are both forms of electromagnetic radiation, which are waves of energy that travel through space at the speed of light.
Radio waves are a type of electromagnetic radiation with longer wavelengths and lower frequencies than microwaves. They are typically used for communication, including radio and television broadcasting, as well as wireless networking and mobile phone communication.
Microwaves, on the other hand, have shorter wavelengths and higher frequencies than radio waves. They are used in a variety of applications, including cooking food in a microwave oven, radar and satellite communication, and wireless communication technologies such as Wi-Fi and Bluetooth.

NSDI '19 - Towards Programming the Radio Environment with Large Arrays of Inexpensive Antennas
Yaxiong Xie, Princeton University
Conventional thinking treats the wireless channel as a given constraint. Therefore, wireless network designs to date center on the problem of the endpoint optimization that best utilizes the channel, for example, via rate and power control at the transmitter or sophisticated decoding mechanisms at the receiver. We instead explore whether it is possible to reconfigure the environment itself to facilitate wireless communication. In this work, we instrument the environment with a large array of inexpensive antennas (LAIA) and design algorithms to configure them in real time. Our system achieves this level of programmability through rapid adjustments of an on-board phase shifter in each LAIA device. We design a channel decomposition algorithm to quickly estim...

Both radio waves and microwaves are part of the electromagnetic spectrum, which includes a range of frequencies and wavelengths that also includes visible light, infrared radiation, ultraviolet radiation, X-rays, and gamma rays. These different types of electromagnetic radiation have different properties and applications, and can have different effects on living organisms depending on their frequency and intensity of exposure.

Yaxiong Xie, Princeton University
Conventional thinking treats the wireless channel as a given constraint. Therefore, wireless network designs to date center on the problem of the endpoint optimization that best utilizes the channel, for example, via rate and power control at the transmitter or sophisticated decoding mechanisms at the receiver. We instead explore whether it is possible to reconfigure the environment itself to facilitate wireless communication. In this work, we instrument the environment with a large array of inexpensive antennas (LAIA) and design algorithms to configure them in real time. Our system achieves this level of programmability through rapid adjustments of an on-board phase shifter in each LAIA device. We design a channel decomposition algorithm to quickly estimate the wireless channel due to the environment alone, which leads us to a process to align the phases of the array elements. Variations of our core algorithm can then optimize wireless channels on the fly for single- and multi-antenna links, as well as nearby networks operating on adjacent frequency bands. We design and deploy a 36-element passive array in a real indoor home environment. Experiments with this prototype show that, by reconfiguring the wireless environment, we can achieve a 24% TCP throughput improvement on average and a median improvement of 51.4% in Shannon capacity over the baseline single-antenna links. Over the baseline multi-antenna links, LAIA achieves an improvement of 12.23% to 18.95% in Shannon capacity.
