9 Simultaneous Transmission with Other
Integrated or Plug-In Radios
The FCC imposes conditions and limitations when additional radio(s) are co-located in the same
host system as the Qualcomm Module with capability to transmit simultaneously.
■ Co-locating other radios, such as an integrated or plug-in wireless WAN/cellular radio with the
Qualcomm wireless LAN module requires additional evaluation and possible submission for
authorization from the FCC
■ The rules are highly dependent on the characteristics of the particular radios that are co-
located and simultaneously transmitting.
□ The OEM integrator should seek guidance from a knowledgeable test lab or consultant to
determine if additional testing and FCC certification is required.
□ In this case, failure to evaluate and follow the required FCC procedures will invalidate the
FCC certification of the Module and end system.
