Abstract: In some examples an electronic device includes a first wireless transceiver, a second wireless transceiver, and a processor. The processor is to transmit data via the first wireless transceiver, detect an indicator of a secure activity, and, in response to a detection of the indicator, stop transmission of the data via the first wireless transceiver and begin transmission of data of the secure activity via the second wireless transceiver.

Abstract: An example radio frequency (RF) front-end module is described, which may include a printed circuit board (PCB) including a ground plane, an RF integrated circuit (RFIC) including RF components mounted on the PCB, and an antenna array on the PCB. The antenna array may operate at a first resonant frequency in a wireless communication network. Further, the RF front-end module may include a slot defined in the ground plane to provide a second resonant frequency in the wireless communication network. The second resonant frequency is lower than the first resonant frequency.
