PMP 450 Planning Guide Glossary
Human exposure to radio frequency energy
Standards
Relevant standards (USA and EC) applicable when working with RF equipment are:
•
ANSI IEEE C95.1-1991, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
•
Council recommendation of 12 July 1999 on the limitation of exposure of the general public to electromagnetic
fields (0 Hz to 300 GHz) (1999/519/EC) and respective national regulations.
•
Directive 2004/40/EC of the European Parliament and of the Council of 29 April 2004 on the minimum health
and safety requirements regarding the exposure of workers to the risks arising from physical agents
(electromagnetic fields) (18th individual Directive within the meaning of Article 16(1) of Directive
89/391/EEC).
•
US FCC limits for the general population. See the FCC web site at http://www.fcc.gov , and the policies,
guidelines, and requirements in Part 1 of Title 47 of the Code of Federal Regulations, as well as the guidelines
and suggestions for evaluating compliance in FCC OET Bulletin 65.
•
Health Canada limits for the general population. See the Health Canada web site at http://www.hc-
sc.gc.ca/ewh-semt/pubs/radiation/99ehd-dhm237/limits-limites_e.html and Safety Code 6.
•
EN 50383:2002 Basic standard for the calculation and measurement of electromagnetic field strength and SAR
related to human exposure from radio base stations and fixed terminal stations for wireless telecommunication
systems (110 MHz - 40 GHz).
•
BS EN 50385:2002 Product standard to demonstrate the compliances of radio base stations and fixed terminal
stations for wireless telecommunication systems with the basic restrictions or the reference levels related to
human exposure to radio frequency electromagnetic fields (110 MHz – 40 GHz) – general public.
•
ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public.
See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying
Electric, Magnetic, and Electromagnetic Fields.
Power density exposure limit
Install the radios for the PMP 450 family of PMP wireless solutions so as to provide and maintain the minimum
separation distances from all persons.
The applicable power density exposure limit from the standards (see Human exposure to radio frequency energy on
page 3-13 ) is:
•
10 W/m
2
for RF energy in the 2.4, 3.5GHz, 3.6 GHz, 5.4-GHz and 5.8-GHz frequency bands.
