phn-2510_002v000 (Mar 2012) 4-9
Human exposure to radio frequency energy
Relevant standards (USA and EC) applicable when working with RF equipment are:
x
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.
x
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.
x
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).
x
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.
x
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.
x
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).
x
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.
x
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 PTP 250 families of PTP 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 4-9 ) is 10 W/m
2
for RF energy in the 5.4 GHz and
5.8 GHz frequency bands.
