Abstract: In a wireless sensor actuator network, a time slot for transmission of a signal to a first device and a second device of the wireless sensor actuator network may be determined. During the time slot, the signal may be transmitted via a first frequency channel and first antenna to the first device and via a second frequency channel and second antenna to the second device in parallel. The first frequency channel may be different from the second frequency channel. Further, the first frequency channel and the second frequency channel may be selected based on a power level to transmit the signal to the first device, a power level to transmit the signal to the second device, an angle to transmit the signal to the first device, and an angle to transmit the signal to the second device.
