2.4Ghz is only used for the bluetooth communication, not for the power transfer. That happens at 5.7-5.8Ghz. "What are the RF spectrums being used by WattUp?"

"What are the RF spectrums being used by WattUp?" [1]
- 2.4GHz (Unlicensed) for Bluetooth Low Energy communication
- 5.7-5.8 GHz (Unlicensed Industrial, Scientific & Medical, ISM) band for power transfer"

- jrockway 12y agoSame EIRP regulations and RF safety regulations for all ISM bands, as far as I can tell. (900MHz has a slightly difference RF exposure calculation that you have to do compared to 1300MHz and up. But 2.4 and 5 are the same.)
