Part Number: WL1837MOD

I want to use my WL1837MOD based product in an outdoor environment in US market.

What is the EIRP limit of WL1837MOD?
Is it possible to increase it's EIRP within regulatory limit?
Will Wilink support increase in EIRP?
Can increase the RF output power by adding the external power amplifier and high gain antenna?
What is the regulatory limit on EIRP for USA?

Hey Kailas,

The EIRP limit will be around the typical values stated in the datasheet. This should only be a 1 or 2db delta. No, it is not possible to increase the power and we do not support this. If the output power is increased with external components, this will nullify our certification, so I do not recommend this.

Certified antenna types are listed here -> http://processors.wiki.ti.com/index.php/WL18xxMOD_Regulatory_Product_Certification#Certified_antenna_types

Our certification reports for WL18xx can be downloaded here -> http://www.ti.com/tool/WL18XX-CERTIFICATION

Hello Seong,

Thanks for response.

What is maximum Wi-Fi RF power limit for USA as per the regulatory authority? Please share the link where I can find the statement of RF power limit.

What if we plan for Class II permissive change with respect to change in Antenna and output power?

Kailas,

Regulations for using ISM bands can be found in part 15 of the FCC rules here. See 15.247b. You could have actually found this in the certificate reports link I shared in my previous post.

Information on C2PC can also be found in the WL18xxMOD Regulatory Product Certification wiki page that I shared in my previous post as well.

BR,

Seong
