3. Device Category and RF Exposure Limit

Per user manual, this device is a wireless remote controller. Based on 47CFR 2.1091, this device
belongs to mobile device category with General Population/Uncontrolled exposure.
Mobile Devices:
47CFR 2.1091(b)
For purposes of this section, a mobile device is defined as a transmitting device designed to be used
in other than fixed locations and to generally be used in such a way that a separation distance of at
least 20 centimeters is normally maintained between the transmitter's radiating structure(s) and the
body of the user or nearby persons. In this context, the term “fixed location” means that the device
is physically secured at one location and is not able to be easily moved to another location.
Transmitting devices designed to be used by consumers or workers that can be easily re-located, such
as wireless devices associated with a personal computer, are considered to be mobile devices if they
meet the 20 centimeter separation requirement.

GENERAL POPULATION / UNCONTROLLED EXPOSURE
The general population/uncontrolled exposure limits are applicable to situations in which the general
public may be exposed or in which persons who are exposed as a consequence of their employment
may not be made fully aware of the potential for exposure or cannot exercise control over their
exposure. Members of the general public would come under this category when exposure is not
employment-related; for example, in the case of a wireless transmitter that exposes persons in its
vicinity. Warning labels placed on low-power consumer devices such as cellular telephones are not
considered sufficient to allow the device to be considered under the occupational/controlled category,
and the general population/uncontrolled exposure limits apply to these devices.

Note:
Per 47CFR 2.1091(c)
Mobile device are subject to routine environmental evaluation for RF exposure prior to equipment
authorization or use if they operate at frequencies of 1.5 GHz or below and their effective radiated
power (ERP) is 1.5 watts or more, or if they operate at frequencies above 1.5 GHz and their ERP is 3
watts or more.
So standalone MPE evaluation is not required for 5.8GHz antenna.
EIRP=P*G, ERP=EIRP-2.15dB

Simultaneous transmission MPE evaluation

There are only one 5.8GHz transmitter incorporated in this remote controller, so simultaneous
transmission is not required.
