3.0 Collocated Installation Guidelines
3.1 Collocated transmitters in mobile applications
Collocated transmitters can be operated simultaneously with the E362 module in mobile
configurations, provided the technical parameters listed in KDB pub 447498 section 8 are met.
These procedures apply to antennas in the display screen for laptop devices.
These parameters are:
a) Transmitters and modules certified for mobile or portable exposure conditions and
categorically excluded by § 2.1091(c) can be incorporated in mobile host devices without
further testing or certification when:
i.
The closest separation among all simultaneous (radiating) transmitting antennas
is
≥
20cm, or
ii. The antenna separation distance and MPE compliance boundary requirements
that enable all simultaneous transmitting antennas incorporated within the host to
comply with MPE limits are specified in the application filing of at least one of the
certified transmitters incorporated in the host device. In addition, when
transmitters certified for portable use are incorporated in a mobile host device the
antenna(s) must be
≥
5 cm from all other simultaneous transmitting antennas.
b) All transmitters in the final product must be at least 20cm from users and nearby persons.
For antenna distance instructions please see section 4.0.
3.2 Collocated transmitters in portable applications
When multiple transmitters are being utilized in a portable configuration all possible combinations
of antennas and transmitters needs to be considered with respect to RF Exposure. Detailed
analysis must be considered when evaluating the affects of multiple transmitters in close
proximity to the end user. Any design that provides multiple transmitters in a portable exposure
condition must be evaluated be Novatel Wireless before integrating the E362.
