Doing my research on FCC certifications, I chanced upon the Particle modules, specifically the Electron 2G (SARA-G350) variety. It looks to be a flexible product and easily integrated into other devices. However, it is unclear to me how the module and antenna certification have been derived.
On the Particle certification page (link here), three links are given. One contains an unintentional radiator test for the Electron module plus antenna and battery. Another contains a Declaration of Conformity, which appears to be based upon the former rapport. Finally, there is a link to several FCC documents, which all seem to refer to the Photon and not the Electron module.
However, it is noted on the certification page that the modules should be listed under a certain FCC number for the intentional radiator/FCC part of the certification. Looking at these FCC numbers, it is clear they are the original U-blox certifications. That makes sense, since these are ‘single-modular transmitter’ certifications and therefore can, and are intended to, be reused. Anyone selling these modules or using them in a product can use the module intentional radiator certification.
However, this is where the part I am unsure of starts. These modules can be used only as long as no changes to the antenna were made. Since these modules do not contain an antenna, I think the rules permit a change to the antenna, as long as it is of a similar type and with equal or lesser gain. I am not sure about that, though, and am not too certain how they apply to a module without antenna either. What I am also unsure of, is how the FCC approved Taoglas antenna came to be. The certification does not seem to list the antenna type used. The gain does appear to be mentioned. Another complication is that the PCB carries the antenna signal, making it part of the antenna structure. Even if the antenna is FCC approved, this causes some concern whether the full product can be considered certified.
In short, my questions are:
- Is the Electron intentional emitter certification based solely upon the U-blox certification?
- How was the Taoglas antenna Particle sells derived from the U-blox FCC Certification?
- Does the Taoglas antenna have separate FCC certification?
- How is the PCB factored in?
The product seems to fit my needs pretty well, so I am curious to learn the answer to these questions. Thank you!
