WL1837MOD FCC co-location certification

Other Parts Discussed in Thread: WL1837MOD, WL1837

I was asked for a WL1837MOD FCC/co-location certification.

In the document "UL_WP_Draft_FCC-Approval-of-Host-Devices-with-Integrated-Wireless-Modules" http://library.ul.com/wp-content/uploads/sites/40/2015/02/UL_WP_Draft_FCC-Approval-of-Host-Devices-with-Integrated-Wireless-Modules_v6.pdf  I found the remark: "Co-location: If other wireless technologies are operational at the same time, additional certification testing is likely to be required"

Is such a certification available?

Regards,
Bernd

    Hi Bernd,

    No, we do not have any such certification. Our WiLink products have BT and WIFI capability, but internal to the device the FW manages the transmission of both and thus only one is operational at a given time. Thus no co-location testing is required.

    If operating with another radio, co-location testing falls on the customer.

    Thanks

    Hi Riz

    I cannot completely agree to your statement "only one is operational at a given time" but does this WL1837 datasheet statement make the "FCC/co-location certification" unnecessary? :

    6.2 Bluetooth Features

    The device supports the following Bluetooth features:

    • .........

    • Concurrent operation and built-in coexisting and prioritization handling of Bluetooth and Bluetooth LE wireless technology, audio processing, and WLAN.

    Hi Bernd,

    The WL18xx is concurrent operation, but it will not transmit both BT and WLAN at the same time. That is you can be connected to BT and WLAN, but at any instance in time you are only transmitting one or the other. WL18xx will determine priority so to the end user, both are operational, but from the RF perspective, only one is active at a given time. Thus co-location testing is not required. This is how all certification for WL18xx has been done as only BT or WLAN is "operational" at a given time.

    Does that make sense?

    Thanks,
    Riz

    Hi Riz,

    absolutely this makes sense.
    Thank you for clarification what I have expected.
