Hi,
1. We didn't certify SRRC so there isn't a FW that supports this testing technically, but I recommend using the latest FW available for this device. SRRC is very similar to ETSI so its very likely they can pass, there may be certain channels where they may need to back of Tx Power for region specific band restrictions. They can build those power limits into their final FW image using uniflash.

2. Slave device without radar detection.
3. For adaptivity, load based non-frequency hopping.
