Other Parts Discussed in Thread: CC1190
Hi,
We build devices based on CC1310 and recently obtained FCC certification for the same. I have a question regarding the two different methods that FCC allows under Section 15.247.
In the document "GUIDANCE FOR COMPLIANCE MEASUREMENTS ON DIGITAL TRANSMISSION SYSTEM, FREQUENCY HOPPING SPREAD SPECTRUM SYSTEM, AND HYBRID SYSTEM DEVICES OPERATING UNDER SECTION 15.247 OF THE FCC RULES" we find the following statement "Equipment certified under Section 15.247 can operate as either a Digital Transmission System (DTS), Frequency Hopping Spread Spectrum (FHSS) system or a Hybrid system, as long as the appropriate requirements for each classification are met. For instance, for a device using digital modulation and frequency hopping, compliance demonstration for both the FHSS requirements and the DTS requirements is not needed. Instead, such a device could be certified by complying with either all the FHSS requirements, or all of the DTS requirements, or all of the hybrid system requirements."
The current FCC certification that we have obtained for our devices is to operate as a digital transmission system. I wanted to check if it would violate the regulations if we use a firmware based on frequency hopping. The certification lab is suggesting that and charging us more to test the devices also for the FHSS operation. However, based on the above document, it seems that we do not have to show compliance with both requirements.
It would be great if someone can help us with this so that we don't get charged two times. Also, what is a hybrid system? I have attached the document.GetAttachment.html.pdf
Thanks in advance,
