1. LW LS RESEARCH A WIRELESS PRODUCT DEVELOPMENT The Advantages of FCC Modular Approval and How to Use it Presented by Thomas T Smith Manager EMC Test Services Presentation Overview Modules provide a quick and easy method to take your product wireless or does it The focus of this presentation is to Briefly discuss what is considered a module How to determine if an FCC Modular Certification exists Discuss key items regarding the FCC Modular Certification What if you want to make changes to the certified module LW LS RESEARCH What is a module Types of modular approvals single split and limited Single modular transmitters consist of a completely self contained radiofrequency transmitter device that is typically incorporated into another product host or device Advantages of the Modular approval Potentially No Additional RF testing is required only unintentional emissions with the radio inside of your product Quicker time to market as design and certification process is complete Minimal RF Wireless expertise required if your modular partner is responsive There are 8 key requirements that need to be met in order for a single modular approval to be allowed The 8 key requirements can be found in CFR Title 47 Part 15 212 a 1 LW LS RESEARCH Abbreviated list of the 8 Points The radio elements of the module requires a RF Shield Module is to have buffered modulation data i
