An unmanned aerial vehicle (UAV) includes a first communication module, a second communication module, and one or more processors. The first communication module is configured to directly receive control data from a controlling terminal via a first communication link and the control data is used to control operations of the UAV. The second communication module is configured to transmit feedback data to a monitoring terminal via a second communication link. The monitoring terminal is located remotely from the UAV. The one or more processors are, individually or collectively, configured to terminate and reactivate the first wireless communication link based on one or more predetermined criteria.

A electronics control unit is in contemporaneous wireless power communication and wireless data communication with a network of sealed, sensors over a shared bidirectional power antenna. Sensors and sensor networks described below enable the development of networks that are secure and robust, and yet are lighter-weight and lower-cost than, for example, conventional automotive sensor networks.

Methods and systems are provided for preventing interference from simultaneous data transmissions in a remote control system. A controlled terminal is typically configured to receive control data from a controlling terminal and to transmit feedback data to a monitoring terminal. To prevent interference caused by the simultaneous transmissions of control data and feedback data. The controlling terminal can transmit the control data to the monitoring terminal, which then transmits the control data to the controlled terminal. Such transmission of the control data may be carried out in a way that does not interfere with the transmission of the feedback data.
