Labeling
The FCC labeling of the PEM module is shown below. When integrating the module into a host, the label
must be visible through a window, visible through an access panel that is easily removed, or a second
label must be placed on the outside of the host device that contains the following text: Contains FCC ID:
BV8BBPBM100. Labelling for Canada must include the following text: Contains IC: 3670A-
BBPBM100.

2.2 RF ENERGY EXPOSURE INFORMATION
2.2.1
Maximum Permissible Exposure Limits
Mobile devices are defined by the FCC as transmitters with a separation distance of at least 20
centimeters between radiating structures and the body of the user. At least 20 centimeters of separation
between the antenna and the user’s body must be maintained at all times.
centimeters between radiating structures and the body of the user. At least 20 centimeters of separation
between the antenna and the user’s body must be maintained at all times.
The FCC defines portable devices as transmitters whose radiating structures are designed to be used
within 20 centimeters of the body of the user. These portable devices are to be evaluated with respect to
limits for specific absorption rate (SAR) and require separate approval.
within 20 centimeters of the body of the user. These portable devices are to be evaluated with respect to
limits for specific absorption rate (SAR) and require separate approval.
The Maximum Permissible Exposure (MPE) is based on a mobile device installation and is specified in
FCC rules 47 CFR 2.1091 Radio frequency radiation exposure evaluation: mobile devices. Since this
device operates at frequencies below 1.5 GHz, the effective radiated power (ERP) is limited to 1.5 watts.

MPE Calculation for Mobile Device Installation
Given the limit for Effective Radiated Power (ERP), we can calculate the maximum antenna gain allowed
for use in a mobile installation:
