LS Reserach App Note for FCC Permessive Change (LSR is TI's recommended Partner for any services
related to Regulatory Certification or Permessive changes)
[3]
Host End Products
• An end product, incorporating€WL1835MODGB module, does not require additional testing or authorization for
the WiFi transmitter as long as
• An antenna of the same or similar type and equal or less gain to the antenna used in the€WL1835MODGB
COM8€Board (WL1835MODCOM8B
[4]
)€is used on the product
• Any restrictions found in the grants are followed in the OEM’s end product integrating the TI module.
• Host end products can use the FCC ID of the certified module as the FCC ID of the host end product
• A label displaying the module’s FCC ID must be affixed and visible on the host end product for approval
• FCC IDs are required for host end products with radio transmitters
Customer's Responsibilities
• The manufacturer of the host end products are still responsible for any additional testing covered by the Class of
the product. Device Class A and B.
• Customers still need to take their products through other FCC/IC testing such as unintentional radiators (FCC sub
part 15B) including any other required regionally driven end product certifications including but not limited to EU
directives.
FCC Part 15 Cert. Process/Flow
Step 1 Step 2 Step 3 Step 4
Sub Part A
• General Provisions &
Definitions
Sub Part B
• Unintentional Radiators
• Devices, whose purpose is not to
produce radio waves,
but which do anyway, such as computers.
Sub Part C
• Intentional Radiators
• Devices designed to produce
coherent radio waves,
such as small transmitters
• Customers can reuse TI's
Certifications
Device Class A and B
• Additional testing for
intended use
Additional testing maybe required for Host end product type.
• Class A: Digital Device for use in a commercial, industrial or business environment.
• Class B: Digital Device for use in a residential environment not withstanding use in commercial, business and
industrial environments.
• The FCC allows for self-declaration for Part B so the process should be relatively painless

Frequently Asked Questions
1. Can the customer change the Antenna Gain?
Answer: Customers that copy the TI Reference Layout and modify it to use a lower gain antenna, can
generally€leverage TI FCC ID through a Permissive Class 1 change.
2. Can the customer change the Layout or use diffeerent type of Antenna?
Answer: Customers that modify the antenna or layout in a way that changes the power (higher gain, shorter traces)
are not able to leverage TI FCC ID through a Permissive Class 1 change. Such changes generally require additional
testing and certification approval through a regulatory lab.
3. How can I get additional information on what is and is not permitted?
Answers: Changes to a modular radio or product will result in either a Permissive Change or a new FCC filing and
