Abstract: An unmanned vehicle receives a message from another unmanned vehicle. The recipient unmanned vehicle uses information included with the message to determine whether a quorum of other unmanned vehicles have vetted information in the message. If a quorum of unmanned vehicles have vetted the message, the unmanned vehicle uses the information in the message to determine how to perform one or more operations.

Abstract: Radio frequency (RF) front-end circuitry and methods of operating the same are described. One apparatus includes multiple antennas and a RF front-end circuitry. The RF front-end circuitry includes: a selection switch coupled to a second antenna, a first RF transceiver coupled to a first antenna and selectively coupled to the second antenna via the selection switch; a second RF receiver coupled to the first antenna; and a third RF transceiver selectively coupled to the second antenna via the selection switch. The first antenna receives signals for the first RF transceiver and the second RF receiver. The selection switch selectively couples the second antenna to the first RF transceiver in a first mode of the RF front-end circuitry and selectively couples the second antenna to the third RF transceiver in a second mode of the RF front-end circuitry.
