Appendix D. Maximum Permissible Exposure
This section has been prepared on behalf of CSL CS101-2 RFID Handheld Reader Device to
show compliance with the RF exposure requirements as defined in FCC Section 47 §1.1307.
Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These
categories are fixed installation, mobile, and portable and are defined as follows:
•
Fixed Installations:
fixed location means that the device, including its antenna, is
physically secured at a permanent location and is not able to be easily moved to another
location. Additionally, distance to humans from the antenna is maintained to at least 2
meters.
•
Mobile Devices:
a mobile device is defined as a transmitting device designed to be
used in other than fixed locations and to be generally used in such a way that a
separation distance of at least 20 centimeters is normally maintained between the
transmitter's radiating structures and the body of the user or nearby persons.
Transmitters designed to be used by consumers or workers that can be easily re-located,
such as a wireless modem operating in a laptop computer, are considered mobile
devices if they meet the 20 centimeter separation requirement. The FCC rules for
evaluating mobile devices for RF compliance are found in 47 CFR §2.1091.
•
Portable Devices:
a portable device is defined as a transmitting device designed to be
used so that the radiating structure(s) of the device is/are within 20 centimeters of the
body of the user. Portable device requirements are found in Section 2.1093 of the FCC's
Rules (47 CFR§2.1093).
The CS101-2 RFID reader is considered as a mobile device as it is used for the purpose of
reading tags.
The FCC also categorizes the use of the device as based upon the user’s awareness and ability
to exercise control over his or her exposure. The two categories defined are Occupational/
Controlled Exposure and General Population/Uncontrolled Exposure. These two categories are
defined as follows:
•
Occupational/Controlled Exposure:
In general, occupational/controlled exposure
limits are applicable to situations in which persons are exposed as a consequence of
