FCC compliance / EMC testing

Hi, hoping someone out there in the community has experience with this and wants to share.

For FCC compliance, do we need to perform host verification testing for wifi? We are getting conflicting information from EMC test labs and are not sure if we need to do any additional testing.

Some are saying we need to perform our own tests, and other labs are saying that it is already FCC certified and so no testing is needed (We agree with the 2nd statement).

We are also curious what other North American users have had to do to meet requirements. Or what they have done to avoid testing an already certified product.

Here is a note from one of the labs we are speaking with:

"XMR201807EG06A (Cell Radio):

Output power is ERP for Part 22 and 27(Below 1 GHz) )and EIRP for Part 24 and 27(Above 1GHz). This grant is valid only when the module is sold to OEM integrators and must be installed by the OEM or OEM integrators. The antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users may not be provided with the module installation instructions. OEM integrators and end-users must be provided with transmitter operating conditions for satisfying RF exposure compliance.

The maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed: 9 dBi in WCDMA/LTE Band 2, 6 dBi in WCDMA/LTE Band 4, 7.42 dBi in WCDMA/LTE Band 5, and 9 dBi in LTE Band 7, 6.7 dBi in LTE Band 12, 7.16 dBi in LTE Band 13, 9 dBi in LTE Band 25, 7.36 dBi in LTE Band 26, 0 dBi in LTE Band 30 and 6 dBi in LTE Band 66.

            2AET4RUTX11 (WiFi Radio):

The listed output power is conducted. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20cm from all persons and not ne co-located with any other transmitters except in accordance with FCC multi-transmitter product procedures in this filing. End-users and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance. This device supports 20MHz and 40MHz bandwidth modes.

This device contains FCC ID: XMR201807EG06A

            The WiFi radio considers the Cell radio, so you are good with respect to RF Exposure. So long as you meet the other requirements you are good with no additional wireless testing. Also note that the WiFi MPE report states that the radios cannot transmit simultaneously, so you can ignore the collocation aspects (antenna separation distance from each other)."

If anybody can help with this we would greatly appreciate it.

Thanks!

Hello,

Usually, some tests can be approved using information from previous tests. For more details, please contact us directly through the “Contact Us” form on our website at Teltonika Networks. Explain your situation, the devices you are planning to use or sell, and the purpose of the information you need. We will do our best to assist you.

Best regards,

Thank you for your prompt reply, Marijus.

We are engaged with Teltonika support directly. Was just curious if the community had any additional information.
