He talks about 5.8ghz configuration depending of the area configuration.I know that P3S only use 2.4g wifi(not 5.8g wifi) frequency for video. RC 5.8 ghz don't use wifi module chip. There is another chip for modulation of RC 5.8ghz. RC 5.8 didn't depend on wifi module.
Many people don't understand that Papatita mod change 5.8ghz configuration too ... to -> BO: DFS-JP , the result "seems" not as good as US: DFS-FCC (but better than "CE" 5.8ghz configuration ^^)
Why do you talk about wifi chip ???
