definition of mobile and fixed devices is:.
Mobile device:
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.
Portable device:
For purposes of this section, 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.

GOODOCOM Technologies Confidential
demonstrated to regulations for other transmitter components within the host product; to requirements for
unintentional radiators (Part 15B). To ensure compliance with all non-transmitter functions the host manufacturer
is responsible for ensuring compliance with the module(s) installed and fully operational. If a host was previously
authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter
certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module
is installed and operational the host continues to be compliant with the Part 15B unintentional radiator
requirements. Since this may depend on the details of how the module is integrated with the host, we suggest the
host device to recertify part 15B to ensure complete compliance with FCC requirement: Part 2 Subpart J
