Just wondering what to expect with the G20 Summit coming to town in a few weeks (Brisbane, Australia). I’ll have a multitude of live crosses to do, and expect that I’ll need to hardwire mics and IFB. Assuming the USSS jamming technology improves from year to year, I would expect that wireless microphones, IFB & cellphones may be jammed while the POTUS / Secret Service motorcade passes by. What experiences have any of you had in recent years, and other than cellphones, what other frequency bands are jammed.
