Specifications

(enclosure). This investigation is especially important when integrating multiple modular
transmitters where the certification is based on testing each of them in a stand-alone
configuration. It is important to note that host product manufacturers should not assume that
because the modular transmitter is certified that they do not have any responsibility for final
product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is obligated
to mitigate the issue. Host products using a modular transmitter are subject to all the applicable
individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15,
and 15.29 to notcause interference. The operator of the host product will be obligated to stop
operating the device until the interference have been corrected .
Additional testing, Part 15 Subpart B disclaimer
The final host / module combination need to be evaluated against the FCC Part 15B criteria for
unintentional radiators in order to be properly authorized for operation as a Part15 digital device.
The host integrator installing this module into their product must ensure that the final composite
product complies with the FCC requirements by a technical assessment or evaluation to the FCC
rules, including the transmitter operation and should refer to guidance in KDB 996369. For host
products with certified modular transmitter, the frequency range of investigation of the
composite system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the range
applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher
frequency range of investigation. When testing the host product, all the transmitters must be
operating. The transmitters can be enabled by using publicly- available drivers and turned on, so
the transmitters are active. In certain conditions it might be appropriate to use a
technology-specific call box (test set) where accessory devices or drivers are not
available. When testing for emissions from the unintentional radiator, the transmitter shall be
placed in the receive mode or idle mode, if possible. If receive mode only is not possible then,
the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to
enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional
radiator circuitry is enabled.
Testing laboratories may need to add attenuation or filters depending on the signal strength of
any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and
ANSI C63.26 for further general testing details. The product under test is set into a
link/association with a partnering WLAN device, as per the normal intended use of the product.
To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending
a file or streaming some media content.
FCC statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
