a. 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 Part 15 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.

Frequency spectrum to be investigated

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.

Operating the host product

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 placed into a normal ‘paired’ mode with another WIFI device, as per the normal

intended use of the product (for example, transferring data).
