What are safe levels of RF radiation?
The SAR is a value that corresponds to the relative amount of RF energy absorbed in the head of a user of a wireless handset. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
What type of standard body is IEEE?
IEEE SA develops standards that are consensus-based and has two types of standards development participation models. These are individual and entity. IEEE SA is not a body formally authorized by any government, but rather a community. ISO, IEC and ITU are recognized international standards organizations.
Has the FCC created guidelines for RF environmental exposure?
FCC Exposure Limits The Federal Communications Commission (FCC) has established safety guidelines relating to RF transmitter sites. The FCC developed limits for human exposure, known as Maximum Permissible Exposure (MPE) limits, in consultation with numerous other federal agencies.
How much frequency is harmful for humans?
300 MHz to 3 GHz
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
What Hz frequencies are harmful to humans?
In addition to decibel levels, harmful sound frequencies can also be damaging to human hearing. Low frequencies (under 20 Hz) and high frequencies (above 20,000 Hz) that humans cannot perceive can also affect the ear and have adverse effects on our health.
What are IEEE standards used for?
Essentially, the IEEE 802 standards help make sure internet services and technologies follow a set of recommended practices so network devices can all work together smoothly. IEEE 802 is divided into 22 parts that cover the physical and data-link aspects of networking.
What are the main IEEE standards?
The most widely used standards are for Ethernet, Bridging and Virtual Bridged LANs, Wireless LAN, Wireless PAN, Wireless MAN, Wireless Coexistence, Media Independent Handover Services, and Wireless RAN. An individual Working Group provides the focus for each area.
Is RF radiation harmful?
The WHO/International Agency for Research on Cancer (IARC) has classified radiofrequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer, associated with wireless phone use.
What is RF compliance?
What is RF Compliance Testing? The “RF” in RF compliance testing stands for Radiofrequency. This testing assures that any wireless devices you’ve produced comply with international regulatory requirements, and it is mandatory for any electronic product that is able to oscillate above 9kHz.
How do you block RF radiation?
Steps to Reduce Radio Frequency (RF) Exposure
- Reduce the amount of time spent using your cell phone.
- Use speaker mode, head phones, or ear buds to place more distance between your head and the cell phone.
- Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power.
How much RF does a cell phone emit?
Cell phones emit radiation in the radiofrequency region of the electromagnetic spectrum. Second-, third-, and fourth-generation cell phones (2G, 3G, 4G) emit radiofrequency in the frequency range of 0.7–2.7 GHz. Fifth-generation (5G) cell phones are anticipated to use the frequency spectrum up to 80 GHz.
